Method for preparing a tufting process for tufting a fabric, in particular carpet
The present invention relates to a method of preparing a tufting process for tufting a fabric, for example a carpet.
When tufting fabrics, assuming an artistic representation that can be, for example, a photo or a drawing, the type of pile, the height of the pile and, in some cases, even the color of the pile must be associated with each pile to be tufted. be determined. On the basis of this information, which relates to all poles that must be present in a tufting substance, a tuft machine control file is generated and a tuft machine is operated based on this tuft machine control file.
Sometimes shortcomings that occur when transferring the information present in the artistic representation to the data present in the control file for the tufting machine only become visible after a substance has been tufted. Making changes to the tuft machine control file and the data used to generate the tuft machine control file, respectively, to remedy such shortcomings is often a very time-consuming and complex task, as it requires variations at the level of the pixels of a pixel grid representative of all poles to be tufted.
It is an object of the present invention to provide a method of preparing a tufting process for tufting a fabric, in particular carpet, allowing easy variation of the structure and / or the optical appearance of a tufting fabric is possible.
According to the present invention, this object is achieved by a method of preparing a tufting process for tufting a fabric, especially carpet, comprising the steps of:
BE2017 / 5770
a) providing a pattern representation representative of a tuftable fabric, comprising at least one tuft structure area corresponding to an area of the multi-pile tuftable fabric,
b) providing, in association with at least one tuft structure area, a tuft structure defined by multiple tuft structure parameters, each tuft structure parameter having an effect on the appearance of at least part of the poles to be tufted in association with this tuft structure area and having no effect on the tuft structure parameters. appearance of poles to be tufted in an area not corresponding to this tufted structure area.
According to the method of the present invention, regions corresponding to regions of a tufting fabric having a specific structure and / or optical appearance are defined. In association with these tufting structure regions, tufting structures are respectively defined and provided, these tufting structures being representative of the structure and / or the optical appearance of each of these regions.
A first tufting structure may define a variation of the pile height within a tufting structure area having the associated first tufting structure, and the tufting structure parameters of the first tufting structure may include the direction of variation and the degree of variation. For example, the degree of variation can be defined by a maximum pile height and a minimum pile height.
To increase the options for providing the structure and / or the optical appearance of a specific region of a tufting fabric, the tufting structure parameters of the first tufting structure may further include the type of pile height variation, and / or may further include the number repeats of the pile height variation within the associated tuft structure area. For example, the type of variation can be defined as a linear variation, a parabolic variation, a hyperbolic variation, a sinusoidal variation or a stepped variation. For example, by providing multiple repetitions of the variation, a corrugated surface structure or a sawtooth surface structure can be obtained.
BE2017 / 5770
According to the present invention, a second tufting structure can define the repetition of a predetermined tufting structure element, wherein the predetermined tufting structure element defines a plurality of poles to be tufted adjacent to each other, in a first direction corresponding to a tufting direction and a second direction substantially perpendicular with respect to the first direction, the tuft structure parameters of the second tuft structure comprising the number of poles of the predetermined tuft structure element in the first direction and the number of poles of the predetermined tuft structure element in the second direction.
The tuft structure parameters of the second tuft structure may further include the pile height and / or the pile type of the poles of the predetermined tuft structure element.
It should be noted that several additional tufting structures can be provided and associated with one or more tufting structure area (s) when preparing a tufting process. Of course, one specific tuft structure area may have multiple tuft structures associated therewith. For example, one specific tuft structure area may have the associated second tuft structure for providing a repetition of a specific tuft structure element in the region of a fabric to be tufted in accordance with this tuft structure area. The first tufted structure can be placed on top of this second tufted structure such that the poles of the repeatedly provided tufted structure elements exhibit a variation of the pile height, for example between two end regions of the area of a fabric corresponding to this particular tufted structure area. Alternatively, starting from tufted structure elements of the second tufted structure that provide at least some poles of equal pile height, in accordance with a repeated variation of the pile height resulting from the association of the first tufted structure with this particular tufted structure area, a variation of the pile height are within each of the tufted structure elements represented in a fabric.
To ensure that a tuft structure parameter associated with a specific tuft structure area only has an effect in this specific tuft structure area, in association with the pattern representation, a pixel grid can be defined, comprising multiple pixels that follow each other in a first
BE2017 / 5770 direction corresponding to a tufting direction and a second direction substantially perpendicular to the first direction, each pixel representing a pile of the tufting fabric, whereby, in association with at least one tufting structure area, the pixels of the pixel grids present within this tuft structure area are determined pixels associated with tuft structure area, and the tuft structure associated with this tuft structure area is applied only to the pixels associated with the tuft structure area.
According to a further very advantageous aspect of the present invention, the method may further comprise a step c) in which the tuft structure of at least one tuft structure area is varied by varying at least one tuft structure parameter of this tuft structure. By providing the option of varying a tuft structure parameter and thereby varying a tuft structure that includes this tuft structure parameter, the structure and / or the optical appearance of the entire tuft structure region associated with this tuft structure is varied. Consequently, stepping in the pixels for varying the information associated with each individual pool to be tufted into a specific region of a fabric can be avoided. If varying the tufting structure is not necessary, this step c) does not need to be performed, although the option to perform this step may be provided to allow for such variations if deemed necessary.
It is further an advantageous aspect of the invention that a variation of tuft structure parameters associated with a specific tuft structure area has an effect only in this specific tuft structure area, but does not affect the information associated with all tuftable poles outside this specific tuft structure area. Therefore, when performing variations on specific tuft structure parameters of a specific tuft structure area, there is no need to worry about the areas outside this tuft structure area, since these variations have no effect in these other areas.
To avoid redundant and / or unauthorized variations, in association with at least one tuft structure, the tuft structure parameters may include variable and non-variable tuft structure parameters, with only the variable tuft structure parameters allowed to be varied. However, provision can be made
BE2017 / 5770 that at least one of the tufting structure parameters can be switched between being a variable tufting structure parameter and being a non-variable tufting structure parameter.
The method of the present invention may further include the step of generating a control file for a tufting machine based on the tufting structure associated with at least one tufting structure area.
The invention further relates to a method for tufting a fabric, comprising the steps of:
- generating a tuft machine control file using the tuft preparation process of the present invention,
- forwarding the tufting machine control file to a tufting machine selected to perform the tufting process,
- operating the tufting machine on the basis of the control file for the tufting machine.
Since flaws in the appearance of a tufted fabric often become visible only after at least part of the fabric has been tufted, according to the present invention, in association with at least one tuft structure area, at least one tuft structure parameter can be varied after at least some tuft structure is, and a new tuft machine control file is generated and used in the tuft machine for tufting a new fabric by running the tuft machine based on this new tuft machine control file.
The present invention will now be elucidated with reference to the annexed drawings, in which:
Fig. 1 shows a pattern representation of a tuftable fabric with a triangular tufted structure region;
BE2017 / 5770
Fig. 2 the tuft structure area of FIG. 1 with a first tufting structure associated therewith;
Fig. 3 shows the portion of the pattern representation of FIG. 1 shows corresponding to the tufting structure area and the associated tufting structure viewed in the direction III in FIG. 2;
Fig. 4 shows a pixel grid associated with the pattern representation of FIG. 1 in the area of the triangular tuft structure area;
Fig. 5 shows a tufted structure element of a second tufted structure.
Fig. 1 shows a pattern representation 10 of a tuftable fabric. For example, the pattern representation 10 may be provided on the basis of an artistic representation, which may be, for example, an image or a drawing showing a triangular area in the center portion thereof. A circumference 12 of the pattern representation corresponds to the outer edge of the tufted fabric.
In association with the triangle shown in the artistic representation, the pattern representation has a correspondingly associated triangular tuft structure area 14. In this particular tuft structure area 14, which corresponds to an area of the tuftable fabric based on this pattern representation 10, comprising multiple poles, a specific structure and / or color appearance of the material to be tufted will have to be provided in accordance with the triangle present in the artistic representation. While, as will be explained in the following, a specific structure will be provided in the area of the tufting fabric corresponding to the tufting structure area 14, in the area 16 outside this tufting structure area 14 and the corresponding area of the tufting fabric, respectively, can be provided. be provided with a uniform structure, for example by providing equal poles with an equal pile height in this area.
In the example shown in Figures 1 to 4, a tufting structure will be associated with the tufting structure area 14 representing a variation of the pile height of the tufts to be tufted in the area associated with this tufting structure area 14
BE2017 / 5770 corresponds. The tuft structure representing this pile height variation includes multiple tuft structure parameters. A first of these tufting structure parameters is the direction D in which the height of the poles varies. A second tuft structure parameter is the degree of variation of the pile height, which can be defined, for example, by the minimum pile height and the maximum pile height.
In the example shown in Figures 1 to 4, the direction D of the pile height variation is provided such that at one point region 18 of the triangular tuft structure region 14 corresponding to the left end region of region A shown in FIG. 3 the minimum pile height min is provided, while at another point area 20 of the triangular tuft structure area 14 corresponding to the right end of the area A shown in FIG. 3 the maximum pile height max will have to be anticipated. This means that a further tuft structure parameter can define that within the tuft structure region 14 there must be only one period, i.e. one repetition, of the pile height variation. A further tufting structure parameter indicates that the type of variation which, in the example shown, is in principle a linear variation. Due to the fact that some tufting machines have a limited resolution in the pile height variability, this linear variation of the pile height to be provided in accordance with one of the tufting structure parameters may be recalculated by, or replaced by, a staggered variation of the pile height. pile height shown by a dotted line in Fig. 3, each stage corresponding to the minimum possible increase / decrease in pile height provided by the particular tufting machine.
As a result of this stepped increase in the pile height between the minimum pile height min and the maximum pile height max, there are three partial areas Pi, P2, P3, each of these partial areas Pi, P2, P3 being an area of uniform pile height.
Fig. 4 shows a portion of a pixel grid 22 associated with the pattern representation 10 of FIG. 1. Each pixel 24 of the pixel grid 22 represents one specific tufting pool, i.e. one stitch to be performed by a needle provided on a tufting machine needle bar. In FIG. 4, the lines of pixels 24 represent respective poles made by one and the same yarn, i.e. by stitching
BE2017 / 5770 performed by one and the same needle provided on a needle bar, especially if the needle bar is not slidable in a needle bar length direction thereof. In tufting machines having a needle bar slidable in a needle bar longitudinal direction, one row of poles corresponding to one line in the pixel grid shown in FIG. 4 are made by stitches made by different needles and can therefore be supplied by different yarns.
In FIG. 4, direction Di corresponds to a tufting direction of a tufting machine, while direction D2, which is substantially perpendicular to direction Di, corresponds to the longitudinal direction of a needle bar and therefore corresponds to the direction in which the needles provided on the needle bar follow each other, and therefore, in which poles formed by adjacent needles succeed one another. This direction D2 almost corresponds to the longitudinal direction of the needle bar. It should be noted that each x represents one pile to be tufted by stitching the needle bar with a needle.
The tufting structure associated with the tufting structure area 14 and indicative of the variation of the pile height within this tufting structure area 14 will be applied to those respective tufting stitches and poles which are within the area corresponding to the tufting structure area 14. This means that the tufting structure will only be applied to those pixels 24 which are within the tufting structure area 14. All those pixels 24 and the tufts to be tufted in association with those pixels outside the tuft structure area 14 will not be affected by the tuft structure associated with the tuft structure area 14. For example, as noted above, in all those pixels 24 outside the tuft structure area 14 may be affected. tuft structure area 14 poles with a uniform pile height. For example, the decision whether or not a specific tuftable pile is within the tufted structure area 14 can be made based on the portion of the area of a respite pixel 24 within the tufted texture area 14. If this portion is above 50%, a respite Pixel 24 can be determined as a pixel associated with a tufted structure region associated with this particular tufted structure region 14. Of course, other ways of determining whether a specific pixel 24 is within or outside a specific tufted structure region may be used.
BE2017 / 5770
In FIG. 3, three groups G1, G2, G3 of poles to be tufted are shown in association with the three subregions P1, P2, P3. Each group Gi, G2, G3 can represent a group of poles tufted from the needle bar by three immediately adjacent needles. For example, these groups G1, G2, G3 can be determined based on a color repetition provided by the thread threading associated with the needles of the needle bars. Thus, each of these three groups G1, G2, G3 corresponds to three lines of the pixel grid 22 shown in FIG. 4.
A further tufting structure parameter of the tufting structure associated with tufting structure region 14 can define which of the yarns contained within each of the groups G1, G2, G3 will be used to form a pile with a pile height corresponding to the varying pile height of this particular tufted structure. In the example shown, only one of the three yarns is used to provide such a varying pile height, while, in association with the other two yarns, poles of uniform, non-varying height are to be formed within the area corresponding to the tuft structure area 14 In another example, all of the yarns threaded through the needles of the needle bar can be used to provide such a varying pile height.
By defining a tuft structure by using multiple tuft structure parameters, for example the minimum pile height, the maximum pile height, the type of pile height variation and the direction of variation, and associating such a tuft structure with a specific tuft structure area, the structure of determine the tuftable fabric in the area corresponding to this tufted texture area without the need to separately define each individual tufted pile in association with each specific pixel 24 within such a tufted texture area by separately providing pile height information in association with each individual pixel 24 and each pool to be tufted, respectively. Only a reduced number of parameters is needed to define a clear structure of an entire tufted structure area and thus an entire tufted area corresponding to such a tufted structure area. Of course, even when the information about the respective tufts is to be tufted in accordance with the principles of the present invention
BE2017 / 5770 is provided, corresponding information about the pile height and the pile type are provided in association with each individual pixel 24 of pixel grid 22 and therefore in association with each individual stitch to be performed when tufting a fabric. Therefore, it could be advantageous to provide multiple virtual layers that can be imaged on a monitor, each layer showing pixels containing identical information about the tufts to be tufted, i.e. showing pixels representing identical poles. Providing such separated layers makes shortcomings that arise when converting the image representation into a series of data useful for tufting a substance, and corrections can be made to overcome such shortcomings, for example, by taking out a specific pixel associated with a tufted structure area outside the tufted structure area and associating such a pixel with the area surrounding this tufted structure area, and for example providing another pile height for the tufted poles in this area.
When preparing a method for tufting a fabric and when performing a method for tufting a fabric, providing an artistic representation and transferring the artistic representation to a pattern representation will associate tufted structure areas with the pattern representation and associating tufting structures with the tufting structure areas are normally done by a designer who can be considered a type of artist who has experience with all the options offered by the tufting process and is therefore capable of transferring the information displayed by the image representation to a series of data displayed by outputting a pixel grid, each pixel representing one pole and one outputtable respectively, to provide a specific type of pool with a specific pole height at a specific location. This can be done, for example, by entering associated data into a data processing means, for example, which includes a programmed microprocessor and / or selecting corresponding information displayed on a screen of a data processing means to thus generate the associated set of data. On the basis of such a set of data, a tuft machine control file can be generated, which is entered into the tuft machine control system to perform a tufting machine
BE2017 / 5770 Tufting process based on this data. There may be an operator of the tufting machine who may be less experienced as far as the artistic aspects are concerned, but who may have more experience of working with the tufting machine and the options offered by such a tufting machine when performing a tufting process. Normally, such an operator is capable of locating specific shortcomings in the data set used to generate the tuft machine control file, for example when they are displayed in separate or superimposed layers, as mentioned above. Of course, such an operator may be able to see such shortcomings after s / he tufts a specific fabric.
In accordance with the principles of the present invention, due to the reduced amount of information required to define the tuft structure of an entire tuft structure area, it is easy to make variations for overcoming such shortcomings or for improving the structural and / or optical appearance of a fabric. For example, if the operator considers that in the tip area 20 there is an excessively sharp transition between the maximum pile height max provided in the tufted structure area 14 and the pile height provided in the area surrounding the tufted structure area 14, the operator may, in accordance with with the principles of the present invention, the maximum pile height which is one of the tuft structure parameters varies, for example, by reducing the maximum pile height and thus reducing the difference between the height of the poles provided within the tuft structure area 14 and the height from the poles outside the tuft structure area 14. This can be done, for example, after a first fabric has been tufted and after such a too sharp transition has been discovered. Of course, such a variation can be performed even before the tufting process is started, if it is discovered early enough and if it is clear that there will be such a shortcoming. In this case, such variation can be performed even before the tuft machine control file is generated. If a tufting machine control file has already been generated and has been used for tufting a fabric, a new tufting machine control file may be generated after performing such variation for subsequent tufting of a new fabric.
BE2017 / 5770
Within the principles of the present invention, one can decide which tufting aspect parameters may be varied. For example, it may be that only the magnitude of the variation can be varied, for example by varying the maximum pile height max and / or the minimum pile height min, while a variation of the direction D and / or a variation of the type variation of the pile height should not be changed. There may even be provided the option of switching specific tuft structure parameters between either a tuft structure parameter that may be varied or a tuft structure parameter that may not be varied. For example, the designer who basically prepares the set of data used to generate the tuft machine control file may be the one who decides which tuft structure parameters can be varied by the operator.
Fig. 5 shows another example of a tuft structure that could be associated with tuft structure area 14. The tuft structure shown in FIG. 5 is based on a tufted structure element 26 which defines a plurality of stitches to be made and poles to be formed, respectively. In the tufted structure element 26, the lines shown in FIG. Represent 5 stitches performed by the same needle and therefore poles generated by the same yarn. The columns will extend in the first direction Di corresponding to the tufting direction of a tufting machine. The lines respectively represent rows of stitches and rows of poles formed by immediately adjacent needles of a needle bar and extend in a direction D2 substantially perpendicular to direction Di.
The tufted structure element 26 shown in FIG. 5 contains four different areas represented by different pile heights 2, 5 on the one hand and 3, 8 on the other. Each such number represents a specific pile height that can be expressed, for example, in millimeters. The pile heights provided within such a tufted structure element 26, as well as the number of poles covered by such a tufted structure element 26 in the two directions Di and D2, can be regarded as tufted structure parameters. If several such tufted structure elements 26 are provided for selection, the information indicating a specific element of these tufted structure elements can also be regarded as a tufted structure parameter.
BE2017 / 5770
The tufted structure provided on the basis of such tufted structure elements 26 defines repeatedly providing such tufted structure elements 26 which follow each other in directions Di and D2 within a tufted structure area having such a tufted structure associated therewith. By varying the numbers of poles and pixels covered by such a structure element 26 and / or by varying the pile heights within the respective pixels, respectively, an effect on all the tuftable poles in an area corresponding to such a tufted structure area can be while there will be no influence on the poles to be tufted outside such an area. The variation within such a tufted structure may also include the replacement of one type of tufted structure element with another type of tufted structure element, if this could provide an improved appearance.
It should be noted that, of course, different or additional tuft structures can be provided and associated with different tuft structure areas of a pattern representation. Of course, such a pattern representation can contain several tufted structure areas. For example, the entire area 16 of which in FIG. 1, it is shown that the tuft structure area 14 surrounding is another tuft structure area with an associated tuft structure associated therewith. Furthermore, several tufting structures can be associated with one and the same tufting structure area.
Of course, the decision to vary one or more of the tuft structure parameters of a tuft structure associated with a specific tuft structure region can be provided in an automated manner. For example, after generating a full set of data defining all the poles to be formed when performing a tufting process, it can be checked whether there are specific areas in which too sharp a transition between adjacent poles occurs. A threshold for a maximum height transition between adjacent poles of a tufting fabric can be defined. If it is established that, at a specific location, this threshold is exceeded, one of the tuft structure parameters, for example the maximum pile height, can be varied. Furthermore, the variation of a tuft structure parameter, for example the minimum pile height, can be limited to a predetermined allowable range, which can be defined for example with respect to another
BE2017 / 5770 tuft structure parameter, for example the maximum pile height. For example, the minimum pile height can be varied in a range from 20% to 50% of the maximum pile height.
The new set of data can be checked again and, if the threshold is still exceeded, the corresponding tuft structure parameter can be varied again. If the threshold is not exceeded, the tuft machine control file can be generated from this data set for subsequent tufting of a substance using this tuft machine control file.
Finally, it should be noted that in accordance with the principles of the present invention, the term at least part of the poles is to be understood as referring to at least two poles.
