    [0001] The present invention relates to a process and a device for the production of a upholstery product. The present invention also relates to a upholstery product as such. In this case, the upholstery product is produced from a strip of flat paper, elongated with one or more layers.
    [0002] EP 1 539 474 B1 discloses a upholstery product that is kneaded from a two-layer paper hose. From the document mentioned there is also known a device and a process with which the upholstery product developed from an elongated paper hose is kneaded.
    [0003] The present invention has, among others, the task of providing a process for the production of a upholstery product that is especially suitable for the upholstery of objects that are in packaging.
    [0004] This task is solved with a process with the characteristics of claim 1.
    [0005] The process according to the present invention comprises the following steps: - Prepare a strip of flat, elongated paper, of two or more layers, where the various layers of the paper strip, in a central region that extends in longitudinally, they are joined to each other, at least in segments, and where the different layers of the paper strip have edge regions that are not joined to each other. - Open the strip of paper in neighboring border regions to obtain a strip of paper with a cross-section in the shape of a star. - Knead the strip of paper along the central region.
    [0006] According to the process according to the present invention, then a flat, elongated strip of two or more layers is prepared. The various layers of the paper strip are joined to each other, at least in segments, along the central region that extends in the longitudinal direction. It is conceivable that the junction is made with a closure due to the shape or with a closure due to the material. In particular, a bonding of the various layers in the central region is especially preferred. The glued joint, in this case, preferably can occur along a line that goes in the longitudinal direction. In this, the glued joint can exist only in segments, for example, in points. But, the glued joint can also be made along a closed line.
    [0007] The different layers of the paper strip also have regions of edges that are not joined together. In the starting state of the strip of paper which can be flat, especially flat by pressure, the neighboring edge regions preferably abut each other. In the case of a two-layer strip of paper whose central region is joined, there are preferably four edge regions, each time two edge regions touching each other in a flat state. But, three or more layers can also be envisaged. In this case, three or more neighboring border regions are foreseen in a flat state. A strip of paper that especially has two layers can be prepared relatively simply. In this it is imaginable that only in the preparation of the strip of paper the different layers are joined to each other in the central region, or that even before the preparation of the strip of paper, that is, in a previous work step, which can also happen in another First, the different layers are joined in the central region.
    [0008] In accordance with the other process step of the present invention, the neighboring edge regions, especially leaning against each other, are opened to form a strip of paper with the star-shaped cross section. Then, on a strip of two-layer paper, a strip of paper in the form of a star appears, with altogether four protruding "rays", and these remain united as before in the central region. In the three-layer forecast, a "star" with six "rays" then appears especially; when forecasting more layers, a "star" with respectively more "rays".
    [0009] The respectively neighboring rays, in this case, preferably form an angle in the range of 60 ° to 120 °, and preferably in the range of 70 ° to 100 °, and especially preferably in the range of 85 ° to 95 °.
    [00010] In the next step of the process, the paper strip is crumpled, at least along the central region. The kneading, in this case, occurs in the longitudinal direction at least along the central region, in such a way that segments of the central region are moved or pushed towards each other, so that the length of the paper strip in a crumpled state, that is, that is, of the upholstery product, it is shorter than the strip of paper in unwrinkled state. This results in greater replacement elasticity in the longitudinal direction of the crumpled strip of paper compared to the uncrumpled strip of paper.
    [00011] The opening of the neighboring edge regions of the paper strip can preferably occur through one or more opening devices, by means of which the paper strip is moved. The movement of the paper strip by means of the opening devices, in this case, preferably can happen mechanically by means of a drive. In particular, it is conceivable that in the central region of the paper strip they attack control pulleys on the paper strip that move the paper strip.
    [00012] Kneading, according to the present invention, can take place with a first group of control pulleys and a second group of control pulleys in such a way that the second group of control pulleys rotates with an angular speed that is less than the angular speed of the first group of drive pulleys. By means of such control pulleys, the paper strip can not only be moved over opening devices; also kneading along the longitudinal direction in the central region can be provided as well. Depending on the size of the difference in the angular speeds of the two groups of control pulleys, a more or less strong wrinkling of the paper strip may occur.
    [00013] For the respective adjustment of an expected length of the upholstery product, it is advantageous when the upholstery product is divided into two regions by braking or stopping the first group of control pulleys, whereas the second group of pulleys command continues to be triggered. Advantageously the two regions are separated from each other by tearing them apart. In this context it is appropriate when the paper strip presents theoretical break points especially in the form of perforations that extend transversely to the longitudinal direction.
    [00014] The task placed is also solved with a device for the production of a upholstery product, especially for carrying out the process according to the present invention, according to the characteristics of claim 5. Such device comprises an entrance region for a flat, elongated strip of two or more layers. The paper strip as such, in this case, is made in such a way that the various layers of the paper strip, in a central region that extends in the longitudinal direction, are joined, at least in segments, to each other, and the layers individual strips of paper have edge regions that are not joined together. The device also provides an opening device for opening the strip of flat paper along neighboring edge regions to form a strip of paper with a star-shaped cross section. The device further provides a feed mechanism for moving the edge regions over at least one opening device, and a kneading mechanism for crumpling the paper strip along the central region. The input region, the opening device, the feed mechanism and the kneading mechanism are preferably carried out in such a way that the process according to the present invention described above can be carried out with the device.
    [00015] Appropriately, the device provides for at least two opening devices opposite one another that are spaced apart in a transverse direction, so that the central region of the paper strip can be moved between the two opening devices. In this way, the border regions of the layers can be opened, so that a strip of paper in the shape of a star appears. The central region of the paper strip where the different layers are joined together can still be moved between the opening devices.
    [00016] Advantageously the opening devices are made in such a way that in the cross section, that is, in the longitudinal direction to the longitudinal direction, they have cuneiform segments facing each other. In this way, the appearance of a strip of paper in the shape of a star in cross section can be guaranteed.
    [00017] In addition, it is advantageous that the opening devices in longitudinal section, that is, in the longitudinal direction, provide opening segments oriented towards the entrance region. Thanks to these opening segments, an opening of the flat paper strip can occur along neighboring edge regions in such a way that the neighboring edge regions are opened away from each other, so that finally a strip of paper appears with the star-shaped cross section. Therefore, the opening segments serve to make the flat paper strip become a paper strip whose cross section has a star shape.
    [00018] In front of the opening devices, in a longitudinal direction, separation elements can be provided that engage between neighboring edge segments. Consequently, the separating elements serve to engage the neighboring edge segments which are arranged on top of each other, in order to guarantee a safe opening of the edge regions. The separation elements are executed in a thin and flat way and, in addition, in the same way as the opening devices, they are separated from each other in a transversal direction, so that between them can pass the central region of the paper strip, where the various layers are joined together. The separating elements can be made especially as separating discs or plates and can also be produced entirely with the opening devices, especially at the wedge-shaped ends of the opening segments.
    [00019] It is also advantageous that a guide pulley is arranged in the entrance region that goes transversely to the longitudinal direction, through which the flat paper strip is guided. This is advantageous when the strip of paper, for example, is unrolled from a reserve roll or removed from a stockpile.
    [00020] The advance mechanism for the movement of the edge regions through the two opening devices can consist of a first group of control pulleys. This first group of drive pulleys may comprise two pulleys arranged on top of each other which respectively attack on the paper strip above and below the central region of the paper strip in a longitudinal direction before the opening cone. The two pulleys, in this case, can be arranged in such a way that they attack the paper strip in the region between the separation elements.
    [00021] Furthermore, it is advantageous that the kneading mechanism is formed by a second group of control pulleys that cooperate with the first group of control pulleys in such a way that the second group of control pulleys can be rotated with a speed angle that is less than the angular speed with which the first group of control pulleys can be rotated. In this way, the paper strip can be moved through the first group of control pulleys; with the second set of control pulleys, the paper strip can be kneaded.
    [00022] In this, the second group of control pulleys can comprise two pulleys arranged one above the other that attack on the paper strip above and below the central region of the paper strip in longitudinal direction in the region between or after the opening cones. It is therefore advantageous that the first group of control pulleys attacks the strip of paper in the region before the opening cone, and the second group of control pulleys, in the region between or after the opening cones.
    [00023] It is also advantageous that the first group of control pulleys and the second group of control pulleys can be driven in such a way that for the division of the upholstery product in two regions the first group of control pulleys can be braked or stopped, and the second group of control pulleys continues to be driven. With this, in a simple way, a division of the upholstery product can be obtained by means of the two groups of control pulleys that provide the kneading.
    [00024] The task mentioned above is also solved by means of an upholstery product which is produced especially according to a process according to the present invention and / or which is produced especially according to a device according to the present invention . Such upholstery product is produced from an elongated paper strip, of two or more layers, where the several layers are joined in a central region that extends in the longitudinal direction, at least in segments, and where the different layers have edge regions. which are not joined together, the neighboring edge regions are opened in a star shape and the paper strip is crumpled, at least along the central region. Such a strip of paper can be produced in a simple way and yet has positive padding properties.
    [00025] Further advantages and advantageous realizations of the present invention are evident from the following description with the help of which an exemplary embodiment of the present invention is described and explained in more detail.
    [00026] They show:
    [00027] Figure 1 shows in perspective a flat strip of paper for the production of an upholstery product according to the present invention.
    [00028] Figure 2 shows the strip of paper according to Figure 1 in a top view.
    [00029] Figure 3 shows a perspective view of a device according to the present invention for the production of a upholstery product.
    [00030] Figure 4 shows the device according to Figure 3 in a side view.
    [00031] Figure 5 shows the device according to Figures 3 and 4 in section along line V of Figure 4.
    [00032] Figure 6 shows a upholstery product according to the present invention.
    [00033] The strip of paper 10 shown in Figures 1 and 2 has two layers 12 and 14. The two layers 12, 14 are arranged on top of each other and have identical external contours. They have an elongated shape, with the central longitudinal axis bearing the reference 16. The strip of paper 10 can be a strip of "endless" paper that can, for example, be unrolled from a roll or can be removed from a pile .
    [00034] The two layers 12, 14 are joined together in their central region 18 which on the strip of paper shown in Figures 1 and 2 goes along the central longitudinal axis 16. Preferably, the two layers 12, 14 are joined together the other along the central longitudinal axis 16 with closure due to the material, especially by means of gluing.
    [00035] The two layers 12, 14 also have border regions 20, 21 and 22, 23 that are not joined together. Therefore, layer 12 has the two edge regions 20, 21. Layer 14 has the two edge regions 22, 23. The edge region 20 of layer 12 is close to the edge region 22 of layer 14. Also the edge region 21 of layer 12 is neighboring edge region 23 of layer 14. In the flat state shown in Figures 1 and 2 of paper strip 10, edge regions 20 and 22 and edge regions 21 and 23 can touch each other. These edge regions 20, 21, 22, 23 will be opened to form rays 26 as will be described later.
    [00036] As seen especially in Figure 2, the strip of paper 10 has regions of theoretical separation 24 that run transversely to the central longitudinal axis 16 that are performed as perforations provided for in layers 20 and 22. With this, the strip of paper 10 it can be divided into two regions along a theoretical separation point 24 by means of longitudinal slits.
    [00037] Figure 3 shows the strip of paper 10 as it is being transformed into a upholstery product. The device 50 shown in Figure 3 is used for this purpose. The device 50 comprises an input region 52 where a guide pulley 56 is provided which is arranged transversely to the longitudinal direction 54 which runs along the central longitudinal axis 16 of the strip of paper 10. The guide pulley 56 is pivotally arranged about an axis of rotation 58, precisely in such a way that the endless paper strip 10 is guided through the guide pulley 56 during the operation of the device 50.
    [00038] The device 50 further comprises two opening devices 58 for opening the flat strip of paper 10 to form a strip of paper 10 'with a star-shaped cross section. The device 50 also comprises an exit region 60 where the strip of paper 10 'opened in the shape of a star is clearly visible.
    [00039] The device 50 further comprises a feed mechanism 62 for moving the paper strip 10 in the device 50, and a kneading mechanism 64 for crumpling the paper strip 10 or 10 'along the central region 18 .
    [00040] As seen in Figures 3 and 5, the opening devices 58 are mutually opposite, and in a transverse direction, that is, vertically to the longitudinal direction 54, they are distanced from each other by the measure 'a'. The measure 'a', in this case, is selected in such a way that the central region 18 of the paper strip 10, that is, the region where the two layers 12 and 14 are connected to each other, can be moved between the two devices opening 58. Especially from Figure 5 it becomes visible that the two opening devices 58 have cuneiform segments 66 that point towards each other. The two cuneiform segments 66 form an angle of about 75 ° to each other.
    [00041] From Figures 3 and 4 it is also visible that the opening devices 58 provide for opening segments 68 in the form of a cone in longitudinal section towards the entrance region 52. During the operation of the device 50, the paper strip 10 is open in the edge regions 20, 21, 22, 23 along the opening segments 68.
    [00042] In order to guarantee a safe opening of the border regions 20, 21, 22, 23, separation elements 70 are arranged, against the longitudinal direction 54 of the opening segments 68, in front of them, which are especially well visible in Figures 3 and 4. The separating elements 70 are separating plates and in the execution example shown in the Figures they are made entirely with the opening devices 58. In the end regions 72 away from the opening segments 68, the separating elements 70 mesh between the edge regions 20 and 22 or 21 and 23 neighboring the paper strip 10, so that the edge regions 20, 21, 22, 23, during operation of the device, can be safely opened by the opening devices 58. The feed mechanism 62 comprises a first group of drive pulleys 74, 76 which in Figure 3 and 4 are shown clearly. The control pulleys 74, 76 are arranged on top of each other and attack the paper strip 10 respectively above and below the central region 18 of the paper strip 10. In the embodiment according to the Figures, the control pulley 76 is driven by a motor 78 through a trapezoidal belt 80. Pulley 74 is applied against pulley 76 under slight pre-tension, so that it is driven together by pulley 76. As already mentioned, between pulleys 74 and 76 are located if a central region 18 of the paper strip 10, a fact that becomes very visible in Figure 3.
    [00043] To crumple the strip of paper 10 along the central region, a second group of control pulleys 82, 84 is provided, which in longitudinal direction 54 is arranged after the first control pulleys 74, 76. According to the first group of control pulleys 74, 76, in the second group of control pulleys 82, 84 also the lower pulley 84 is driven by another electric motor 78, precisely by means of another V-belt 80. The upper pulley 82 under tension preview is separated against the lower pulley 84, so that it rotates together with the pulley 84.
    [00044] As can be seen especially from Figure 4, the first group of control pulleys 74, 76 in longitudinal direction 54 is located in front of the opening devices 58, and precisely in the region between the two separation elements 70. As well as is visible from Figure 4, the second group of drive pulleys 82, 84 is located in the region between the two opening devices 58. In Figure 5 it is visible that drive pulleys 82, 84 and drive pulleys 74 , 76 have a width 'b' that is slightly less than the distance 'a' between the opening devices 58.
    [00045] The angular speed of the pulleys 82, 84 of the second drive group can be selected such that it is slightly less than the angular speed of the control pulleys 74, 76 of the first group. In this way, a kneading of the paper strip 10 is provided in the central region 18 in a kneading zone 86, with the kneading zone 86 located between the two groups of pulleys 74, 76 and 82, 84. Therefore, the strip of paper 10 leaves the device in the outlet region 60 as a padding product, which, on the one hand, is open in the shape of a star and, on the other hand, is kneaded especially in the central region. It should be noted that in Figures 3 and 4 the pulleys 74, 76 and 82, 84 rotate with the same angular speed, so that the strip of paper 10 'is not crumpled here. The strip of paper 10 'coming out of the device 50 therefore has the central region 18 which is guided between the pulleys 72, 74 and 82, 84. In this central region 18 follow the edge regions 20, 21, 22, 23 which were opened in a star shape by means of the opening devices 58, that is, the four "spokes" 26 of the open paper strip 10 '. In this, the central region 18 has a width that corresponds to the width 'b'. It is conceivable to reduce the width 'b' to a very small measure or even a line. For kneading, as already described, the angular speed of the pulleys 74, 76 is increased, or that of the pulleys 82, 84 is reduced.
    [00046] As described, such upholstery product can be produced in a simple way, and also has good upholstery properties.
    [00047] Although in the Figures a strip of paper 10 showing only two layers is shown, it is conceivable that a strip of paper which has three or more layers is also used. The three or more layers are then connected to each other in the central region 18, or preferably in the region of the central longitudinal axis 16. In place of two opposing opening devices 58, then suitably four or more opening devices that mesh in the intermediate spaces are used appropriately. between the border regions respectively neighboring the respective layers.
    [00048] In order to divide the endless strip of paper 10 into different regions, it is advantageous that the first group of control pulleys 74, 76 is stopped when the second group of control pulleys 82, 84 continues to be actuated, so that a separation occurs along a theoretical separation region shown in Figures 1 and 2.
    [00049] Figure 6 shows a strip of crumpled 10 '' paper, produced with the device 50, i.e., the finished upholstery product 88. The crumpled central region 18 with a width 'b' is clearly visible, which is followed by edge regions 20, 21, 22, 23 or radii 26.
