Background Art

[0002] EP3603401A1 discloses an apparatus and method for splitting a fabric mass. The disclosed apparatus includes a storage chamber for storing the fabric mass and a pair of rotary cutters disposed at the opening of the outlet of the storage chamber.

Summary of the Invention

Problems to be Solved by the Invention

[0003] It is an object of the present invention to provide an improved splitting roller assembly. This object is achieved by a splitting roller assembly having the features of claim 1. Advantageous improvements are provided in the dependent claims.

Means for Solving the Problems

[0004] The present invention discloses a splitting roller assembly arranged to manufacture fabric parts from fabric blocks. The splitting roller assembly includes a first splitting roller having a plurality of separating edges and rotatably mounted about a first rotation axis, and a second splitting roller having a plurality of separating edges and rotatably mounted about a second rotation axis. The first splitting roller and / or the second splitting roller each have a plurality of depressions provided between two separating edges. The splitting roller assembly further includes a scraping device including a scraper and a scraping drive device arranged to move the scraper along the first splitting roller and / or the second splitting roller.

[0005] By moving the scraper along the splitting roller, fabric residues undesirably adhering to the roller can be removed. In particular, the scraper may be movable in a scraping direction along the splitting roller, and the scraping direction may be oriented parallel to the rotation axis of the splitting roller to be scraped. Another advantage may be shown in removing excess release agents, which are not discharged, for example, together with the manufactured fabric parts. In this way, the accumulation of release agents in the splitting roller assembly can be avoided.

[0006] The scraping device may include one scraper or several scrapers. For example, the scraper may be arranged to move along the first split roller and the second split roller, especially for removing fabric residues on the two split rollers. In this case, advantageously, the scraper can be driven by a scraping drive device. In addition, the scraper may be arranged to move only along the first split roller, especially for removing fabric residues on the first split roller, or may be arranged to move only along the second split roller, especially for removing fabric residues on the second split roller. Here, advantageously, the scraping device includes a first scraper arranged to move only along the first split roller and a second scraper arranged to move only along the second split roller. The first scraper and the second scraper may be drivable by one common scraping drive device. Similarly, the drive device may be arranged to drive the first scraper, that is, it may be considered to include a first scraping drive device arranged to move the first scraper along the first split roller. In addition, the drive device may be arranged to drive the second scraper, that is, it may also include a second scraping drive device arranged to move the second scraper along the second split roller.

[0007] The scraper may be arranged to cooperate with one of the plurality of depressions. This makes it possible to remove the fabric residues as completely as possible.

[0008] Advantageously, the scraper can move in the sliding region of the scraping drive device and is longer than the first dividing roller and / or the second dividing roller in a direction parallel to the rotation axis. Thereby, it is possible for the scraper to slide beyond at least one end face of one dividing roller or two dividing rollers, whereby, on the one hand, the fabric residue can also be pushed beyond the end face and thus removed from the dividing roller. On the other hand, such a sliding region allows the scraper to be placed in a stop position which enables the scraper to pass by when the dividing roller rotates. The end face of the dividing roller may be regarded as the side surface of the dividing roller which is oriented substantially perpendicular to the rotation axis of the dividing roller. Particularly advantageously, the scraper can slide beyond the two end faces of the first dividing roller and / or the second dividing roller. Thereby, the fabric residue can be removed in two sliding directions of the scraper and it is possible to install stop positions on both sides of the dividing roller. Thereby, it is possible to accelerate the scraping process, specifically, there is no need to return the scraper after or before scraping.

[0009] The dividing roller assembly is expected to be arranged to apply a release agent to the surface of one of the plurality of depressions after moving the scraper along the depression. Due to the presence of the scraper, the release agent residue can also be removed from the dividing roller, particularly from the surface of the depression, thereby enabling the regeneration of the release agent film. In particular, a reproducible release agent film can be realized by periodically removing the release agent from the dividing roller, particularly from the surface of the depression, and reapplying it to the dividing roller, particularly to the surface of the depression.

[0010] The parting roller assembly may further include a release agent applying device that can be arranged to apply a release agent to the surface of one of the plurality of depressions of the first parting roller. The release agent applying device may include a nozzle that can be arranged to generate a conical spray beam. When the first parting roller is arranged at the spraying position, the nozzle may have a first separation edge defining the depression and a first distance measured in the spraying direction, and the spraying direction may be oriented to be parallel to the conical spray beam axis of the conical spray beam, and the first distance may be smaller than a second distance measured in the spraying direction between the nozzle and a second separation edge defining the depression. When the first parting roller is arranged at the spraying position, the nozzle may further have a first lateral distance measured in the lateral direction between the first separation edge defining the depression, and the lateral direction may be oriented to be perpendicular to the spraying direction, and the first lateral distance may be smaller than a second lateral distance measured in the lateral direction between the nozzle and a second separation edge defining the depression.

[0011] Such an arrangement makes it possible to position the nozzle particularly close to the parting roller. The conical spray beam widens as the distance in the spraying direction increases. Since the lateral distance from the separation edge farther from the nozzle in the spraying direction is larger, it is possible to avoid the release agent being sprayed beyond the farther separation edge due to the widening of the conical spray beam.

[0012] The ratio of the second distance measured in the spraying direction to the first distance measured in the spraying direction may exceed, for example, 1.5, preferably exceed 2.5, and particularly preferably exceed 3. The ratio of the second lateral distance measured in the lateral direction to the first lateral distance measured in the lateral direction may exceed, for example, 1.25, preferably exceed 2, and particularly preferably exceed 2.3.

[0013] The nozzle can be considered to move along the first splitting roller, particularly to move parallel to the first rotation axis. The splitting roller assembly, particularly the mold release agent application device, can have a nozzle drive device that is arranged to move the nozzle along the first splitting roller, particularly to move parallel to the first rotation axis. Incidentally, the scraping drive device can be considered to be arranged to move the nozzle along the first splitting roller, particularly to move parallel to the first rotation axis. Here, the scraping drive device may be the first scraping drive device described above, and the first scraping drive device may be arranged to drive the first scraper, that is, it may be arranged to move the first scraper along the first splitting roller. Incidentally, the scraping drive device is the scraping drive device described in the same way as above, and the scraping drive device can be considered to be arranged to drive the first scraper and the second scraper simultaneously.

[0014] Regarding the mold release agent application device, hitherto, only the possible application of the mold release agent to the surface of one of the recesses of the first splitting roller has been clearly described. However, those skilled in the art will understand that the mold release agent application device may be arranged to apply the mold release agent to the surface of one of the plurality of recesses of the second splitting roller. The mold release agent application device may include, for example, a second nozzle. All the descriptions before and after the nozzle or the first splitting roller can be similarly applied to the second nozzle or the second splitting roller.

[0015] The nozzle and the second nozzle can move together along the first splitting roller and, in particular, can move parallel to the first rotation axis. The nozzle drive device is arranged to move the nozzle along the first splitting roller and, in particular, parallel to the first rotation axis, and to move the second nozzle along the second splitting roller and, in particular, parallel to the second rotation axis. However, the nozzle and the second nozzle may be movable separately. Note that the splitting roller assembly, in particular the release agent application device, may have a second nozzle drive device that can be arranged to move the second nozzle along the second splitting roller and, in particular, parallel to the second rotation axis. Similar to the nozzle, the second nozzle can be moved by the second scraping drive device described above, and the second drive device may be arranged to drive the second scraper, that is, it may be arranged to move the second scraper along the second splitting roller. Note that the second nozzle can be moved by a scraping drive device, and the scraping drive device is arranged to drive the first scraper and the second scraper simultaneously.

[0016] The present invention further relates to a fabric splitting device including a container and a splitting roller assembly of the type described above.

[0017] The present invention further relates to a method of applying a release agent to a split roller by a release agent application device, the release agent application device including a nozzle arranged to generate a conical spray beam, and the split roller being rotatably mounted about a first axis of rotation. The method includes pivoting the nozzle about a pivot axis by a pivoting drive device and, after pivoting the nozzle, sliding the nozzle along the split roller by a nozzle drive device. Such movement of the nozzle enables positioning the nozzle closer to the split roller that needs to be wetted with the release agent, thereby reducing the portion of the release agent that flows out of the nozzle and does not reach the split roller. Since the positioning is closer, the degree to which the conical spray beam generated by the nozzle opens may be smaller, and at the same time, due to the sliding and pivoting movements, the entire surface of the split roller that needs to be wetted can be wetted with the release agent.

[0018] It is conceivable that the pivot axis and the axis of rotation are oriented substantially parallel to each other.

[0019] The method may further include sliding the nozzle before pivoting the nozzle. In particular, sliding the nozzle before pivoting the nozzle and sliding the nozzle after pivoting the nozzle may be performed in the same or opposite sliding directions. It may be particularly advantageous to slide the nozzle along the entire axial length of the split roller during sliding before and / or after pivoting. Thereby, it may be particularly advantageous that sliding the nozzle before pivoting the nozzle and sliding the nozzle after pivoting the nozzle are performed in opposite sliding directions.

[0020] Disclosed is a method for separating a fabric portion from a fabric mass by means of a fabric splitting device including a container, a first splitting roller having a plurality of separating edges, and a second splitting roller having a plurality of separating edges. One recess is provided between two separating edges respectively. The method includes rotating the first splitting roller and the second splitting roller to a storage position, in which the first separating edge of the first splitting roller and the second separating edge of the second splitting roller have a storage distance from each other, storing a portion of the fabric mass in two recesses facing the container of the first splitting roller and the second splitting roller, rotating the first splitting roller and the second splitting roller to a waiting position, in which the first separating edge of the first splitting roller and the second separating edge of the second splitting roller have a waiting distance from each other. The method can further include reducing the rotational speeds of the first splitting roller and the second splitting roller and waiting for a waiting time. The method can further include increasing the rotational speeds of the first splitting roller and the second splitting roller and rotating the first splitting roller and the second splitting roller to a separating position, in which the first separating edge of the first splitting roller and the second separating edge of the second splitting roller have a separating distance from each other. The storage distance can be greater than the waiting distance, and the waiting distance can be greater than the separating distance.

[0021] By rotating to the waiting position, the fabric splitting device may first open slightly without completely separating the fabric portion from the fabric mass. During the waiting time, the fabric portion may begin to detach from the splitting roller. In particular, the waiting time can be used to wait for the fabric mass to at least partially detach. Thereafter, the fabric portion can be completely separated by continuing to rotate it to the separating position. This method enables the fabric portion to first detach from the area of the splitting roller and then fall from the fabric splitting device, thereby enabling a cleaner fall. In addition, the risk that the fabric portion is torn by adhering to the area where it moves laterally outward of the splitting roller can be reduced.

[0022] Advantageously, the waiting time can be set. Thereby, the waiting time can be adapted, for example, to different fabric properties, and due to these fabric properties, the fabric mass can rapidly detach from the dividing roller at different speeds. For example, the waiting time may be at most 10 seconds, preferably at most 5 seconds, and particularly preferably 2 seconds.

[0023] It is conceivable to rotate the first dividing roller at a first angle between the storage position and the waiting position and to rotate the second dividing roller at a second angle between the storage position and the waiting position. Particularly advantageously, the first angle and the second angle are equal. This can simplify the control with respect to rotation. For example, the first angle may be 60° to 80°, preferably 70°.

[0024] Advantageously, reducing the rotational speed of the first dividing roller and the second dividing roller includes reducing it by 50% or more, preferably by 80% or more, and particularly preferably by 90% or more. Particularly advantageously, reducing the rotational speed of the first dividing roller and the second dividing roller includes reducing it by 100%, in particular stopping the first dividing roller and / or the second dividing roller. Reducing the rotational speed as much as possible is advantageous for the detachment of the fabric mass.

[0025] Furthermore, a dividing roller or a dividing roller assembly of the above type used in a fabric dividing device is disclosed. The dividing roller may be arranged to divide the fabric and may be rotatably mounted about a rotation axis. The dividing roller may have several separating edges, and one recess may be provided between every two separating edges. The surface of the recess may have a first partial surface and a second partial surface which may have different surface properties and / or different shapes. Due to these different surface properties and / or different shapes, these partial surfaces can be optimized for their different functions.

[0026] The surface of the recessed portion may have two or more partial surfaces, and each of the partial surfaces among the partial surfaces can have surface characteristics different from the surface characteristics of one or some of the other partial surfaces. The surface characteristics can be different in terms of characteristics such as roughness, stripes, coating material and / or coating characteristics, adhesion tendency (especially anti-adhesion characteristics), lipophilic or lipophobic, lipophilic or lipophobic, hydrophilic or hydrophobic.

[0027] The first partial surface and the second partial surface may be separated by a single dividing line, preferably a virtual dividing line. The dividing line may be oriented, for example, parallel to the axis of rotation. This can be advantageous because it can adapt to different rotational positions or movement requirements with different surface characteristics. Note that the dividing line can extend non-linearly, for example, in a wavy manner. The first partial surface can be located on the side facing the rotational direction of the separating edge adjacent to the recessed portion with respect to the separating edge adjacent to it. This side facing the rotational direction of the adjacent separating edge always cooperates with the fabric mass in the same way, thus making it possible to optimize the surface characteristics of the first partial surface with respect to such cooperation. Alternatively or additionally, the second partial surface can be located on the side facing the direction opposite to the rotational direction of the adjacent separating edge with respect to the separating edge adjacent to it. This side facing the direction opposite to the rotational direction of the adjacent separating edge always cooperates with the fabric mass in the same way, thus making it possible to optimize the surface characteristics of the second partial surface with respect to such cooperation.

[0028] The present invention further relates to a fabric dividing apparatus including a container and at least one, preferably two, of the aforementioned types of dividing roller assemblies.

[0029] The present invention relates to an apparatus and method of the aforementioned type. Hereinafter, several representative embodiments will be described in more detail with reference to the drawings.

MODE FOR CARRYING OUT THE INVENTION

[0031] In FIG. 1, a fabric splitting device 1 is shown in a schematic cross-sectional view. The fabric splitting device 1 may include a container 2. The container 2 may be arranged to store a fabric mass 3. The fabric splitting device 1 may further include a splitting roller assembly 4. The splitting roller assembly 4 can manufacture fabric parts 5 (see FIG. 3) from the fabric mass 3. The fabric splitting device 1, particularly the splitting roller assembly 4, may include a first splitting roller 6. Note that the fabric splitting device 1, particularly the splitting roller assembly 4, may include a second splitting roller 7. The first splitting roller 6 may be rotatably attached about a first rotation axis 8, or may be attachable in this way. The second splitting roller 7 may be rotatably attached about a second rotation axis 9, or may be attachable in this way. The first splitting roller 6 may be rotatable about the first rotation axis 8 in a first rotation direction 10. The second splitting roller 7 may be rotatable about the second rotation axis 9 in a second rotation direction 11. The first rotation direction 10 and the second rotation direction 11 may be oriented to face each other.

[0032] Each of the splitting rollers in the splitting rollers 6 and 7 may have several separating edges. One recess may be provided between every two separating edges. The first splitting roller 6 may have a first separating edge 12. The first splitting roller 6 may further have a second separating edge 13. A recess 14 may be provided between the first separating edge 12 of the first splitting roller 6 and the second separating edge 13 of the first splitting roller 6. Note that the second splitting roller 7 may have a first separating edge 15. Note that the second splitting roller 7 may have a second separating edge 16. Another recess 18 may be provided between the first separating edge 15 of the second splitting roller 7 and the second separating edge 16 of the second splitting roller 7.

[0033] In FIG. 1, the first split roller 6 and the second split roller 7 located at the storage position A are shown. At the storage position A, the first separation edge 12 of the first split roller 6 and the second separation edge 16 of the second split roller 7 may have a storage distance 17 from each other. The storage position A enables a part of the fabric mass 3 to be stored in the recesses 14, 18. The gap between the second separation edge 13 of the first split roller 6 and the first separation edge 15 of the second split roller 7 may actually be very small. In FIG. 1, this gap is enlarged for easier viewing of these two separation edges.

[0034] FIG. 2 shows the fabric splitting device 1 from the same perspective. However, the shown first split roller 6 and second split roller 7 are located in a rotated orientation with respect to FIG. 1. The arrangement of the first split roller and the second split rollers 6, 7 shown in FIG. 2 is hereinafter referred to as the waiting position W. At the waiting position W, the first separation edge 12 of the first split roller 6 and the second separation edge 16 of the second split roller 7 may have a waiting distance 19 from each other. After rotating the first split roller 6 and the second split roller 7 from the storage position A to the waiting position W, the rotational speeds of the split rollers 6, 7 can be reduced. Thereafter, a waiting time may be waited, where the rotational speeds of the first split roller and the second split rollers 6, 7 can be kept reduced during this waiting time. Thereby, it is possible to wait for the fabric mass 3 to disengage from the recesses 14, 18. After waiting for the waiting time, the rotational speeds of the first split roller 6 and the second split roller 7 can be increased again. Thereafter, as shown in FIG. 3, the split rollers 6, 7 can be rotated to the separation position T.

[0035] At the separation position T, the first separation edge 12 of the first dividing roller 6 and the second separation edge 16 of the second dividing roller 7 may have a separation distance 20 from each other. The separation distance 20 may be very small, and for easier viewing, the separation distance is shown enlarged in FIG. 3. As seen in FIGS. 1 to 3 of the embodiment, the storage distance 17 may be greater than the waiting distance 19. The waiting distance 19 may be greater than the separation distance 20. As seen in FIG. 3, the separation distance 20 may be small enough that the fabric portion 15 is completely separated from the fabric mass 3. By waiting in advance for the fabric to detach from the recesses 14, 18, it is possible to achieve that the fabric portion 5 can fall with higher reproducibility.

[0036] The waiting time can be set, for example, to take into account the density of different fabrics. For example, the waiting time may be at most 10 seconds, preferably at most 5 seconds, and particularly preferably 2 seconds. The first dividing roller 6 can be rotated at a first angle 21 between the storage position A and the waiting position W. The second dividing roller 7 can be rotated at a second angle 22 between the storage position A and the waiting position W. As shown in this embodiment, the magnitudes of the first angle 21 and the second angle 22 may be the same. The first angle may be 60° to 80°, preferably 70°. Reducing the rotational speeds of the first dividing roller 6 and the second dividing roller 7 can include, for example, reducing by 50% or more, preferably by 80% or more, and particularly preferably by 90% or more. Particularly advantageously, the rotational speeds of the first dividing roller 6 and the second dividing roller 7 can be reduced by 100%, and in particular, the dividing rollers 6, 7 can be stopped.

[0037] The recessed portions 14 and 18 will be described in more detail below. Here, the following description should be regarded as an example for all the recessed portions. In FIG. 4, a perspective view of the fabric dividing apparatus 1 is shown. Since the shown dividing rollers 6 and 7 are in a continuously rotating position, the recessed portion 18 can be seen better. The recessed portion 18 may have a surface 23. The surface 23 may have a first partial surface 24. The surface 23 may further have a second partial surface 25. As shown in different patterns in the present embodiment, the first surface 24 and the second surface 25 may have different surface characteristics. The first partial surface 24 and the second partial surface 25 can be separated by a virtual dividing line 26 shown by a dotted line in FIG. 4. As seen in the embodiment, the dividing line 26 may be oriented parallel to the second rotation axis 9.

[0038] The recessed portions 14 and 18 will be described in more detail below. Here, the following description should be regarded as an example for all the recessed portions. In FIG. 4, a perspective view of the fabric dividing apparatus 1 is shown. Since the shown dividing rollers 6 and 7 are in a continuously rotating position, the recessed portion 18 can be seen better. The recessed portion 18 may have a surface 23. The surface 23 may have a first partial surface 24. The surface 23 may further have a second partial surface 25. As shown in different patterns in the present embodiment, the first surface 24 and the second surface 25 may have different surface characteristics. The first partial surface 24 and the second partial surface 25 can be separated by a virtual dividing line 26 shown by a dotted line in FIG. 4. As seen in the embodiment, the dividing line 26 may be oriented parallel to the second rotation axis 9.

[0039] When the dividing rollers 6 and 7 are oriented in the storage position A, those partial surfaces, i.e., the second partial surface 25, which are located much on the side facing the direction opposite to the corresponding rotation directions 10 and 11, are seen to support the major part of the weight of the fabric mass 3. For this reason, it can be advantageous that these partial surfaces are set with surface characteristics different from those of the first partial surface.

[0040] FIG. 5 shows a schematic cross-sectional view of another embodiment. The same reference numerals denote the same structures. As shown in FIG. 5, compared with the above-described embodiment, the splitting roller assembly 4 may include a scraping device 29. The scraping device 29 may include a scraper 30. The scraping device 29 may further include a scraping drive device 31. The scraping drive device 31 may be arranged to move the scraper 30 along the first splitting roller 6. As shown in this embodiment, the scraping device 29 may include a second scraper 30a. The scraping direction 120 may further include a second scraping drive device 31a. The second scraping drive device 31a may be arranged to move the second scraper 30a along the second splitting roller 7. The second scraper 30a having the second scraping drive device 31a may be arranged to be similar to the scraper 30 having the scraping drive device 31. To avoid repetition, hereinafter, only the scraper 30 and the scraping drive device 31 will be described. However, all the descriptions are also applicable to the second scraper 30a or the second scraping drive device 31a.

[0041] The scraper 30 may be arranged to cooperate with the recess 14 of the first splitting roller 6. That is, the shape of the scraper 30 can be adapted to the shape of the recess 14. The scraper 30 can slide in the sliding region 32 (see FIG. 6) of the scraping drive device 31. As shown in this embodiment, the sliding region 32 may be oriented parallel to the first rotation axis 8 and / or the second rotation axis 9, and may be in a sliding direction 33 that is longer than the first splitting roller and / or the second splitting rollers 6, 7. In particular, the sliding region 32 may be slidable beyond the end faces 34 or 35 of the first splitting roller 6 or the second splitting roller 7.

[0042] As shown in this embodiment, the split roller assembly 4 may include a release agent application device 36. The release agent application device 36 may include a nozzle 37. The release agent application device may be arranged to apply a release agent to one of the surfaces 23 of the recesses 14, 18. The nozzle 37 may be arranged to generate a conical spray beam 38. In particular, the nozzle 37 may be arranged to spray the release agent in the spray direction 39. The spray direction 39 may be regarded as a direction oriented parallel to the conical spray beam axis 40. The direction oriented perpendicular to the spray direction 39 is hereinafter referred to as the lateral direction 41.

[0043] In FIG. 5, a split roller assembly located at the spray position S is shown. The spray position S is a position where a release agent can be sprayed onto the split rollers 6, 7. When the split rollers 6, 7 are arranged at the spray position S, the nozzle 37 may have a first distance 42 measured in the spray direction 39 from the first separation edge 12 of the first split roller 6. The nozzle 37 may also have a second distance 43 measured in the spray direction 39 from the second separation edge 13 of the first split roller 6. The first distance 42 may be smaller than the second distance 43. The nozzle may have a first lateral distance 44 measured in the lateral direction 41 from the first separation edge 12. The nozzle 37 may have a second lateral distance 45 from the second separation edge 13. The first lateral distance 44 may be smaller than the second lateral distance 45.

[0044] The release agent application device 36 may further include a second nozzle 37a. All of the foregoing descriptions regarding the nozzle 37 are also applicable to the second nozzle 37a.

[0045] The mold release agent application device 36 may have a nozzle drive device 46. The nozzle drive device 46 may be arranged to move the nozzle 37 along the first split roller 46. Similarly, the mold release agent application device 36 may include a second nozzle drive device 46a that can be arranged to move the second nozzle 37a along the second split roller 7. All the nozzle drive devices and the scraping drive device may be screw drive devices or cylinder drive devices, particularly air cylinder drive devices, or a combination thereof.

[0046] In FIGS. 7 to 9, another embodiment of the fabric splitting device 1 is shown. The same reference numerals still refer to the same structures. In FIG. 7, a schematic cross-sectional view of the fabric splitting device 1 is shown. Similar to the embodiment described above with reference to FIGS. 5 and 6, based on the embodiment shown in FIG. 7, the fabric splitting device 1 may include a mold release agent application device 36. Similarly, similar to the embodiment described with reference to FIG. 5, the mold release agent application device 36 may include a nozzle 37 and a nozzle drive device 46.

[0047] Different from the embodiment described above, in this embodiment, the nozzle 37 is rotatable. For this reason, the mold release agent application device 36 may include a rotation drive device 47. The rotation of the nozzle 37 may be performed about a pivot axis 48, and the pivot axis may be oriented parallel to the first rotation axis 8. As seen from FIG. 7, in this embodiment, a second nozzle 37a implemented in the same manner as the nozzle 37 may be further provided. The nozzle 37 can alternately rotate about the pivot axis 48 and slide along the first split roller 6 so as to wet the entire surface 23 of the recess 14 with the mold release agent. Here, different movement sequences are conceivable, and these movement sequences are exemplarily shown in FIGS. 8 and 9 (for a clearer view, refer to the second split roller 7). In FIG. 8, a movement pattern is described in which the nozzles 37, 37a are slid after one rotation and continue to slide in the same direction after the next rotation. In FIG. 9, a movement pattern is described in which the nozzles 37, 37a are slid along the entire axial length of the corresponding split rollers 6, 7 before and after rotation, where the sliding direction before rotation and the sliding direction after rotation are oriented to be opposite.

[0048] The embodiments described above, particularly the combinations of features described herein, are to be understood as illustrative. Those skilled in the art will recognize that the features disclosed within the scope of the description of the various embodiments can be combined.
