    Method for preparing a tufting process for tufting a fabric, in particular carpet
    The present invention relates to a method for preparing a tufting process for tufting a fabric, for example a carpet.
    When tufting a fabric, for example a carpet, a three-dimensional surface structure of such fabric can be obtained by providing a variation of the pile height. This can be done, for example, to emphasize the optical appearance of specific areas of such a fabric by providing such areas with poles of increased pile height.
    It is an object of the present invention to provide a method of preparing a tufting process for tufting a fabric, in particular a carpet, which allows the formation of a complex three-dimensional surface structure of a tufting fabric.
    According to the present invention, this object is achieved by a method of preparing a tufting process for tufting a fabric, comprising the steps of:
    a) selecting at least one object to be displayed on a tufted fabric as a drtedtmenstonal tuft structure element,
    b) three-dimensionally scanning the at least one object to provide a series of three-dimensional scan data representing at least a portion of the three-dimensional structure of the at least one object,
    c) providing a series of tufting instruction data based on the three-dimensional scan data, the tufting instruction data, in association with the at least one three-dimensional tufting structure element to be tufted, comprising information relating to at least
    BE2017 / 5769 one tufting aspect of the tufting poles to provide the at least one three-dimensional tufting structure element.
    In accordance with the principle of the present invention, the data containing the information relating to the three-dimensional surface structure of a tufting fabric is generated from a series of data that directly reflects the three-dimensional structure of an object that is on the fabric as a three-dimensional tuft-textured element must be shown. As a result of providing this data reflecting the three-dimensional structure of such an object by performing a three-dimensional scanning process, a time-consuming and complex procedure for manually defining, for example, the pile height of each individual pile to be tufted to form the three-dimensional structural element can be avoided.
    It should be noted that according to the principle of the present invention, an object can be a complete object or constructional element, such as a car, or a part thereof.
    For example, the pile height can be such a tufting aspect of the tufts to be tufted. Naturally, other tufting aspects, for example the pile type of a specific tuftable pile, can be used as an alternative or as a supplement.
    To provide information regarding the entire tufting fabric, it is proposed that the tufting instruction data, in association with each pile of the tufting fabric, contains information pertaining to at least one tufting aspect.
    To provide clear information regarding the tuftable poles, a pattern representation representative of the tuftable fabric may be provided, the pattern representation comprising the at least one three-dimensional tufted structure element. For example, in association with the pattern representation, a pixel grid can be defined, comprising a plurality of pixels following each other in a first direction corresponding to a tufting direction and a second direction substantially perpendicular to the first direction, each pixel being one pole of represents the fabric to be tufted, wherein, at least in association with the at least one three-dimensional
    BE2017 / 5769 tuft structure element, the tuft instruction data, in association with each pixel of the pixel grid, includes information related to the at least one tuft aspect.
    To improve the optical appearance of a fabric to be tufted and to emphasize the three-dimensional texture effect generated by a varying tufting aspect, for example a varying pile height, a color representation representative of the color appearance of the object can be provided, and the Tufting instruction data is provided based on the color representation. Therefore, the pile color can be used as an additional tufting aspect.
    In addition, when the pile color is used as one of the tufting aspects defining a specific pile, at least in association with the at least one three-dimensional tuft structure element, the tuft instruction data, in association with each pixel of the pixel grid, may include information relating to the pile color.
    The method may further include the step of generating a tuft machine control file based on the tufting instruction data.
    In addition, a further aspect, the invention relates to a method for tufting a fabric, comprising the steps of:
    generating a control file for a tufting machine by using the method for preparing a tufting process according to the invention, forwarding the control file for the tufting machine to a tufting machine selected to perform the tufting process, operating the tufting machine based on the control file for the tufting machine.
    The present invention will now be elucidated with reference to the annexed drawings, in which:
    BE2017 / 5769
    Fig. 1 is a drawing showing the step of three-dimensional scanning of an object;
    Fig. 2 shows a pattern representation of a tufting fabric comprising the three-dimensional object shown in FIG. 1 has been scanned as a three-dimensional tufted structure element;
    Fig. 3 is a portion of a pixel grid corresponding to region III of FIG. 2 shows;
    Fig. 4 is a portion of a pixel grid corresponding to area IV of FIG. 2.
    In FIG. 1, an object 110 is shown to be used, in the context of the following explanation of the present invention, as an object to be displayed on the surface of a tufted fabric, for example, a carpet, as a three-dimensional surface textured element. While, in FIG. 1, object 110 is shown as a cube, it is clear that the present invention can be used in combination with any three-dimensional object, for example, a house, a tree, a car, etc., or a part or detail with a specific surface texture thereof. After such an object 110 is selected as an object to be displayed on a tufted fabric as a three-dimensional tufted structure element, a 3D scanning process using a 3D scanning device 111 is performed to provide a series of three-dimensional scan data representing the three-dimensional structure of object 110. This can be done, for example, by moving 3D scanning device 111 to different locations for viewing object 110 from different directions, by moving 3D scanning device 111 around object 110, or by positioning this 3D scanning device 111 at a specific location , allowing the generation of three-dimensional scan data from object 110 representative of the three-dimensional character of object 110 to be displayed on the tufting fabric. For example, if the perspective view of object 110 shown in FIG. 1 if a three-dimensional tufted structure element is to be provided on a tufted fabric, for example carpet, viewing object 110 from this side may be sufficient, while data provided by viewing object 110 from the rear may not be necessary.
    BE2017 / 5769
    Based on the three-dimensional scan data provided by the three-dimensional scanning of object 110, a series of tufting instruction data reflecting the three-dimensional character of object 110 can be provided. This will be explained below with reference to Figures 2 to 4. It should be noted that the data processing of the three-dimensional scan data can be performed by one or more data processing means comprising, for example, a programmed microprocessor, which receives the scan data for generating of tufting instruction data and which finally generate a tuft machine check file to enter into a tuft machine and tuft a substance based on this check file.
    Fig. 2 shows a pattern representation 112 which can be provided as a representation of a tufting fabric, for example a carpet, having a circumference 114 corresponding to a circumference of the tufting fabric. Pattern representation 112 shows a three-dimensional tufted structure element 116 to be provided in a tufted fabric corresponding to object 110, for example, in a center portion thereof. It should be noted that several different objects can of course be provided as one and the same pattern representation 112 as corresponding three-dimensional tufted structure elements.
    In association with pattern representation 112, a pixel grid comprising multiple pixels can be defined, each pixel representing one pool to be tufted. For example, this pixel grid may contain lines of pixels that follow each other in a first direction Di corresponding to a tufting direction, while the pixel grid may contain columns of pixels which follow each other in a second direction D2 which is substantially perpendicular to the first direction Di and which, for example, corresponds to a longitudinal direction of a needle bar of a tufting machine. Several needles are provided on such a needle bar, which follow each other in the second direction D2. A yarn is passed through each needle of the needle bar, so that a row of poles corresponding to a line in the pixel grid is used by each needle and the yarn passed through it, respectively.
    BE2017 / 5769 can be tufted. It should be noted that in a tufting machine with a sliding needle bar, one row of poles can be tufted using different needles, for example, with yarns differently colored therethrough, so that rows of poles successive in the tufting direction corresponding to Di and those different colors have been tufted.
    The tufting instruction data, in association with each such pixel of a pixel grid and each pool to be tufted, respectively, contains information pertaining to at least one tufting aspect. If a fabric showing a three-dimensional surface structure has to be tufted, the pile height can be used as one such tufting aspect. When using a tufting machine with a sliding needle bar, the pile color can be used as an additional tufting aspect.
    Based on the three-dimensional scan data, the tufting instruction data is provided so as to reflect the three-dimensional structure of the object 110 in the three-dimensional tufted structure element 116. For example, the structure of the three-dimensional scan data may be such that the positioning of respective regions of the scanned object within the space and / or relative to each other is indicated. In another example, such relative positioning of certain areas of the scanned object can be determined or calculated based on the scan data.
    When tufting a fabric based on pattern representation 112 shown in FIG. 2, in a region 118 around tuft structure element 116, for example, a predetermined pile height can be set as a default value. For example, if the tufting machine used to perform the tufting process is arranged to provide poles with twenty different pile heights, a number 1 can represent a pole with the minimum pile height, while a number 20 can represent a pole with a maximum pile height. In pattern representation 112 shown in FIG. 2, the minimum pile height 1 may be associated with area 118 surrounding tuft structure member 116.
    Based on the three-dimensional scan data, in association with each pixel of the pixel grid in the area covered by tufted structure element 116, the
    BE2017 / 5769 pile height can be determined. For example, in association with those parts of object 110 and tufted structure element 116, respectively, which represent the most elevated areas, which, when looking at three-dimensional object 110, which are areas closest to a virtual viewer, the maximum pole height 20 can be used , while in association with those portions which, relative to area 118, are the least elevated areas, and thus, when looking at three-dimensional object 110, those areas positioned with the greatest or maximum distance from a virtual viewer, the minimum pile height 1 or a slightly increased pile height can be used. Since, in a perspective view of object 110 to be provided as a three-dimensional tufted structure element in the tufted fabric, a front 120 of object 110 corresponds to the most elevated portion of the three-dimensional tufted structure element 116, pile height 20 can be associated with this front 120 and a corresponding portion 120 'of tufted structure member 116. A side face 122 of object 110 is inclined with respect to front 120 such that a corresponding area 122' of tufted structure member 116 will have a varying pile height decreasing from the maximum pile height 20. The same holds true for an area 124 'corresponding to an upper side 124 of object 110.. It should be noted again that associating a specific pile height representing a tufting aspect for a specific set of tufting instruction data is performed by a data processing means based on the information contained in the scan data showing the relative positioning of parts of a scanned object relative to represents each other and towards a virtual viewer.
    Figures 3 and 4 show parts of a pixel grid 126 associated with pattern representation 112 in which each pixel 128 corresponds to a pool to be tufted. Therefore, in association with each such pixel, the tufting instruction data contains information about at least one tufting aspect, for example the pile height of a pile to be tufted.
    BE2017 / 5769
    Fig. 3 shows the transition from area 118 around tufted structure element 116 to area 120 'representing the most elevated area of tufted structure element 116. Therefore, as indicated above, pole height 20 will be associated with each pixel 128 of the pixel grid 126 located in this region 120 '. Since, in area 118, as in area 120 ', there should be no variation of the pile height, in association with each pixel and therefore in association with each pile to be tufted in these areas, uniform pile heights 1 and 20 will be associated with the tuft aspect pool height is selected and will therefore be reflected in the tuft information data.
    Fig. 4 shows the transition between region 120 'and region 122' of tufted structure element 116. Due to the fact that region 122 'represents side plane 122, which is oblique to front 120 and therefore, in a perspective view, starting from an edge 130 , having an increasing distance to front 120, the pile height in region 122 'decreases, starting from a line 132 indicating the transition between regions 120' and 122 '. In FIG. 4, this decrease in pile height is reflected by the diminishing numbers representing the pile height within each pixel 128 of region 122 '.
    Usually, object 110 will have an extension between the rearmost portion thereof and the frontmost portion thereof, which is significantly greater than the difference between the maximum pile height and the minimum pile height. Therefore, when transforming the three-dimensional scan data into the tuft information data representing the pile height, a mathematical scaling operation can be performed to transform the extension of object 110 between its frontmost part and its most rear part to an extension corresponding to the maximum difference between the maximum pile height and the minimum pile height used to generate the varying pile height of tufted structure element 116.
    In addition to the pile height information, the tuft information data may contain pile color information as an additional tuft aspect. For example, a photo of object 110 can be taken and used as a color representation. In association with each pixel within tufted structure element 116, a specific color corresponding to
    BE2017 / 5769 the predominant color of a corresponding area of this color representation can be used to define a specific pool color. Naturally, the number of available pile colors is limited, even if a tufting machine with a sliding needle bar is used. This information related to the pile color can be added to the information related to the pile height and therefore the three-dimensional texture effect generated by poles of different heights can be emphasized by a color variation that can resemble the color variation of object 110 when viewed from viewed in a specific direction.
    After defining such a set of tuft information data, a tuft machine control file is generated based on this data. This tufting machine control file is entered into the tufting machine and the tufting machine is operated based on this tufting machine control file which converts the information contained in the tufting information into commands for running a tufting machine. The fabric tufted on the basis of such a tuft machine control file will have the appearance depicted in a pattern representation with a three-dimensional tufted structure element in the center showing a raised area 120 'with uniform pile height behind a face is defined by the poles of reduced uniform height present in region 118. In addition, this three-dimensional tufted structure element will have two regions corresponding to regions 122 'and 124' shown in the pattern representation 112 and having poles with decreasing pile height starting from the maximum pile height provided in area 120 '.
    As mentioned above, multiple different tufted texture elements within one and the same tufted fabric can be provided by selecting correspondingly different objects, scanning these objects to provide three-dimensional scan data and, in association with each such object and the corresponding three-dimensional tufted texture element, providing of tuft information data that reflect at least the pile height as one tuft aspect to determine a three-dimensional structure.
    BE2017 / 5769
    Starting from the series of data corresponding to the three-dimensional scan data that can be provided, for example, to represent the entire three-dimensional structure of a scanned object, this data and the scanned object, respectively, can be displayed on a monitor by well-known software. By rotating the object, the viewing angle can be changed, the view corresponding to the view to be displayed on a carpet can be selected, and the tuft information data can be generated from such a specifically selected perspective view of the three-dimensionally scanned object.
