The present invention comprises a sizing tank comprising a bottom plate, front and rear end walls, and left and right side walls, in which size liquid is stored, a collection section including a collection tank for collecting the size liquid used for sizing, and a warp sheet wound around the sizing tank. a first squeeze roll provided behind the sizing roll so as to circumscribe the sizing roll on the upstream side in the advancing direction of the warp sheet; and a sizing roll so as to circumscribe the sizing roll on the downstream side in the advancing direction. A size supply device for supplying size to form a size pool in a wedge-shaped area formed above a second squeeze roll provided on the front side of the roll and a circumscribing position between the sizing roll and the first squeeze roll. wherein the sizing tank is capable of immersing the sizing roll and/or the second squeeze roll in the sizing liquid in the tank, and the rear end wall extends in the front-rear direction. The present invention relates to a warp sizing device provided so as to be located on the rear side of the circumscribing position between the sizing roll and the first squeeze roll.

As a warp sizing device as described above, for example, there is one disclosed in Patent Document 1. The warp sizing device disclosed in Patent Document 1 includes a sizing tank in which size liquid is stored, and a first roll (sizing roll) around which the warp sheet is wound and immersed in the size liquid in the sizing tank. It has In addition, second and third rolls that circumscribe the sizing roll are provided on the front side and rear side of the sizing roll, respectively. Further, the warp sizing device includes a size supply device for supplying size to form a size pool in a wedge-shaped area formed above the circumscribed position between the rear second roll and the sizing roll. ing.

In addition, the second and third rolls are provided so as to press against the sizing rolls. As a result, the warp sheet that has passed through the size liquid supplied by the size liquid supply device or the size liquid of the sizing tank passes between the rolls and the sizing rolls to remove excess size liquid from the warp sheet. is squeezed out. Therefore, the second and third rolls are so-called squeeze rolls. Further, the warp sizing device is provided with a recovery section for recovering the sizing liquid used for sizing.

In addition, in the warp sizing apparatus of Patent Document 1, the recovery section includes a recovery path through which the size liquid flows down and a recovery tank for recovering the size liquid.

JP-A-2003-96657

By the way, when the warp sheet passes through the size liquid as described above, foreign substances such as fluff and fluff of the warp threads and oil adhering to the warp threads are mixed in the size liquid. Therefore, a general warp sizing device continuously supplies new size liquid to the inside of the sizing tank and the above-described wedge-shaped area so that the old size liquid overflows. So, foreign substances are discharged together with the old paste liquid.

In addition, the sizing liquid overflowing from the sizing tank flows down directly to the collecting section and is collected as described above. Also, the size liquid overflowing from the size liquid reservoir formed in the wedge-shaped region is also recovered by the recovering section. However, not all of the size liquid overflowing from the size liquid pool flows down directly to the collection section, and some of the size liquid may also flow down into the sizing tank.

Specifically, the aforementioned wedge-shaped region exists above the circumscribed position of the sizing roll dipped in the glue bath and the squeeze roll. Therefore, the side walls of the gluing tank are positioned outside the wedge-shaped regions (sizing rolls, squeeze rolls) in the width direction. In addition, the collecting section exists in a range that includes the gluing tank in plan view. The size reservoir is positioned above the sizing tank, and the size liquid overflows violently from the size reservoir and flows outward. However, not all of the size liquid that flows down reaches the outside of the sizing tank, and it may bounce off the walls of the components of the warp sizing device on the outside, and part of it will be inside the sizing tank. It may also flow down.

When the size liquid from the size pool runs down into the sizing tank, the size liquid in the tank contains not only the foreign substances mixed in by the warp sheets being directly immersed, but also the size running down from the size liquid pool. Foreign matter in the liquid is also mixed. As a result, the amount of foreign matter mixed in the size liquid in the sizing tank increases, and as described above, there is a possibility that the foreign matter cannot be discharged as expected by supplying new size liquid. If the state in which the foreign matter is not discharged as expected continues, the state of the sizing liquid in the tank may deteriorate, which may adversely affect the sizing of the warp sheets.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a warp sizing apparatus capable of suppressing deterioration of the state of size liquid in a sizing tank.

In order to achieve the above object, the present invention is based on the premise of the warp sizing device as described above. It is characterized by having a receiving portion that exists at least in a range of the portion that includes the existence range of the size liquid pool in the front-rear direction.

Further, in the present invention, the receiving section may be configured by a separate member from the gluing tank and the recovery section. Furthermore, the receiving part may be provided so as to extend to the outside of the gluing tank in the width direction. In addition, the receiving part has an inclined surface for flowing the overflowing size liquid from the upper side to the lower side, a guiding surface for directing the flow of the overflowing size liquid to the outside of the sizing tank, and an inclined surface. and a regulating surface for regulating the overflowing size liquid from flowing down into the sizing tank.

According to the warp sizing device according to the present invention, the warp sizing device has a receiving portion existing at least in the range described above between the wedge-shaped region and the side wall of the sizing tank in the width direction. . As a result, the size liquid flowing down from the size liquid pool is received by the receiving portion, so that the falling size liquid is less likely to enter the sizing tank. Therefore, the amount of foreign matter mixed in the size liquid in the sizing tank is reduced compared to the conventional case, and the problem that the foreign matter mixed in the size liquid in the tank is not discharged as expected is less likely to occur. As a result, deterioration of the state of the sizing liquid in the sizing tank is suppressed.

Further, if the receiving section is configured as a separate member from the sizing tank and the recovery section, it is possible to apply the receiving section to an existing warp sizing device by retrofitting the receiving section. Furthermore, if the receiving portion is provided so as to extend to the outside of the sizing tank in the width direction, the sizing liquid received by the receiving portion can be more effectively guided to the outside of the sizing tank.

Further, if the receiving portion is configured to have the inclined surface, the guiding surface and the regulating surface as described above, the sizing liquid received by the receiving portion can be effectively restricted from flowing down into the sizing tank. Therefore, it is possible to more effectively suppress deterioration of the state of the sizing liquid in the sizing tank.

An embodiment (example) of a warp sizing device to which the present invention is applied will be described below with reference to FIGS. 1 to 4. FIG.

The warp sizing device 1 includes a sizing tank 3 that stores a sizing liquid S, a sizing roll 11 around which the warp sheet T is wound and immersed in the sizing liquid S, and a first squeeze roll 13 that circumscribes the sizing roll 11. and a second squeeze roll 15 . The warp sizing device 1 also includes a size liquid supply device 20 for supplying the size liquid S from above to the circumscribed position between the sizing roll 11 and the first squeeze roll 13 . Details of each component of the warp sizing device 1 are as follows.

The gluing tank 3 has a substantially rectangular shape in a plan view, and includes a bottom plate 4 forming a bottom surface, front and rear end walls 5 and 6 and left and right side walls 7 and 7 standing upright from four edges of the bottom plate 4, respectively. It is formed with The long side direction of the rectangular bottom surface is the width direction of the gluing tank 3 (the direction in which the side walls 7 and 7 face each other), and the short side direction is the front-rear direction (the direction in which the end walls 5 and 6 face each other). It's becoming

In addition, a supply unit 30 connected to a supply source of the paste liquid S, which will be described later, is provided on the rear end wall (rear end wall) 6 of the paste vat 3 . The sizing liquid S is supplied to the sizing tank 3 through the supply unit 30, and the sizing liquid S is stored in the tank.

The sizing roll 11 is a roll around which the warp sheet T is wound, and is rotatably supported by a frame (not shown) of the warp sizing device 1 by support shafts 12, 12 attached to both ends thereof. In addition, the sizing roll 11 is positioned within the existence range of the gluing tank 3 in a plan view, and is provided so that its axial direction coincides with the width direction. The sizing roll 11 is provided such that its lower end is located below the upper edge of the front end wall (front end wall) 5 in the vertical direction. As a result, when the size liquid S is stored in the sizing tank 3 , the lower portion of the sizing roll 11 is immersed in the size liquid S.

The warp sizing device 1 is provided with a drive mechanism (not shown) that rotates the sizing roll 11, and the sizing roll 11 is actively driven to rotate as the warp sheet T advances. ing. Then, the warp sheet T is guided by being wound around the sizing roll 11, and in the process, the warp sheet T is immersed in the size liquid S and impregnated with the size liquid S. As shown in FIG.

In addition, a second squeeze roll 15 for squeezing the sizing liquid S in the sizing tank 3 impregnated from the warp sheet T is provided so as to be positioned on the front side of the sizing roll 11 . The second squeeze roll 15 is rotatably supported with respect to the frame by support shafts 16, 16 attached to both ends of the second squeeze roll 15 with its axial direction aligned with the axial direction of the sizing roll 11. . The second squeeze roll 15 is supported by the frame via a pressing mechanism (not shown), and is provided so as to circumscribe the sizing roll 11 while being pressed. Therefore, the second squeeze roll 15 is driven to rotate as the sizing roll 11 is driven to rotate as described above.

In addition, the vertical arrangement of the second squeeze rolls 15 is such that the axis thereof is located slightly above the axis of the sizing rolls 11 in this embodiment. Therefore, the circumscribed position of the second squeeze roll 15 with respect to the sizing roll 11 is slightly above the support shaft 12 in the vertical direction on the outer peripheral surface of the sizing roll 11 .

After that, the warp sheet T wound around the sizing roll 11 as described above passes between the sizing roll 11 and the second squeeze roll 15 which are in contact with each other as described above, and then is pulled out to the outside. be When passing between the sizing rolls 11 and the second squeeze rolls 15, excess size liquid S is squeezed from the warp sheet T impregnated with size liquid S as described above.

Further, on the upstream side of the sizing roll 11, a supply nozzle 24 for supplying the size liquid S for impregnating the warp sheet T with the size liquid S on the upstream side, and a size liquid S supplied by the supply nozzle 24 are provided. A first squeeze roll 13 is provided for squeezing.

More specifically, the first squeeze roll 13 is rotatably supported with respect to the frame by support shafts 14, 14 attached to both ends of the first squeeze roll 13 with its axial direction aligned with the axial direction of the sizing roll 11. It is Like the second squeeze roll 15, the first squeeze roll 13 is also rotatably supported by the frame via the pressing mechanism. Therefore, the first squeeze roll 13 is also in contact with the sizing roll 11 while being pressed, and is driven to rotate as the sizing roll 11 is driven to rotate.

Further, in this embodiment, the first squeeze roll 13 is provided at a position such that its axial center substantially coincides with the axial center of the second squeeze roll 15 in the vertical direction. That is, the first squeeze roll 13 is provided symmetrically with respect to the sizing roll 11 in the front-rear direction. Therefore, the circumscribed position of the first squeeze roll 13 with respect to the sizing roll 11 is substantially the same in the vertical direction as the circumscribed position of the second squeeze roll 15 with respect to the sizing roll 11 on the outer peripheral surface of the sizing roll 11. . The circumscribed position of the sizing roll 11 and the first squeeze roll 13 is positioned slightly forward of the rear end wall 6 of the gluing tank 3 in the front-rear direction.

The first squeeze roll 13 circumscribes the sizing roll 11 in such a way that a wedge-shaped region 17, which is a wedge-shaped gap, is formed between the sizing roll 11 and the first squeeze roll 13. Become. A supply nozzle 24 for supplying the size liquid S toward the wedge-shaped area 17 is provided above the wedge-shaped area 17 .

A plurality of the supply nozzles 24 are arranged in the width direction at predetermined intervals within the existence range of the sizing roll 11 in the width direction. Then, the size liquid S is supplied from above to the wedge-shaped area 17 through each of the supply nozzles 24 , thereby forming a size reservoir 18 in which the size liquid S is accumulated in the wedge-shaped area 17 .

Then, the warp sheet T is guided so as to be wound around the first squeeze roll 13, and after passing between the circumscribing sizing roll 11 and the first squeeze roll 13 as described above, It is wound around the sizing roll 11 as follows. Then, the warp sheet T is impregnated with the size liquid S by passing through the size liquid pool 18 formed between the two rolls. When the warp sheet T impregnated with the size liquid S passes between the sizing roll 11 and the first squeeze roll 13, excess size liquid S is squeezed from the warp sheet T.

Each of the supply nozzles 24 is a part of the size liquid supply device 20 for supplying the size liquid S from above to the wedge-shaped region 17 as described above, and the warp sizing apparatus 1 has such a size liquid. A feeding device 20 is provided. The size liquid supply device 20 includes, in addition to the supply nozzle 24 described above, a supply tank 22 as a supply source of the size liquid S supplied to the supply nozzle 24 . In the size liquid supply device 20, the supply tank 22 and the supply nozzles 24 are connected by a pipe line 26, and a pump P is provided in the pipe line 26. The paste liquid S is supplied to the nozzle 24 . Further, in this embodiment, the pipe line 26 is branched and connected to the supply section 30 , and the size liquid supply device 20 supplies the size liquid S also to the sizing tank 3 .

In addition, in the warp sizing device 1, as the size liquid S is supplied to the sizing tank 3, the stored size liquid S overflows out of the tank. Therefore, the warp sizing apparatus 1 is provided with a recovery box 40 below the sizing tank 3 for receiving the overflowing sizing liquid S and for discharging the sizing liquid S to the supply tank 22 described above.

Like the gluing tank 3, the collecting box 40 is formed in a housing shape with an open upper side, and the gap between the front wall 41 and the rear wall 42 is in the short side direction (the front-rear direction) of the gluing tank 3. Moreover, the distance between the left and right side walls 43, 43 is larger than the size of the gluing tank 3 in the long side direction (the width direction). Each lateral wall 43 is sized so as to face the sizing roll 11 and the first squeeze roll 13 when viewed in the width direction.

In addition, the size liquid S in the size liquid reservoir 18 in the wedge-shaped region 17 also overflows to both sides of the sizing roll 11 and the first squeeze roll 13 due to the supply of the size liquid S from the supply nozzle 24. The overflowing size liquid S is also received by the recovery box 40 . The warp sizing apparatus 1 is configured such that the size liquid S received in the recovery box 40 is flowed to the supply tank 22 and recovered. Therefore, in this embodiment, the supply tank 22 for collecting the size liquid S used for sizing corresponds to the collection tank referred to in the present invention, and the combination of the supply tank 22 and the collection box 40 corresponds to the collection section referred to in the present invention. corresponds to

In the warp sizing device 1 as described above, in the present invention, for the purpose of suppressing deterioration of the state of the size liquid in the sizing tank, the warp sizing device is provided with a sizing roll in the width direction and both sides of the sizing tank. Between the wall or one of the side walls, there is a receiving portion that exists at least in a range that is part of the range from the side wall in the width direction and that includes the range in which the size pool exists in the front-rear direction. . The warp sizing device 1 of this embodiment is configured to have a receiving member 50 which is separate from the sizing tank 3 and the recovery section (recovery box 40). It is designed to have a receptacle. Further, this embodiment is an example in which the receiving members 50 are provided on both sides of the sizing roll 11 in the width direction.

One embodiment (this example) of such a warp sizing device 1 according to the present invention will be described in detail below. However, since both receiving members 50 and each configuration around the receiving members 50 are the same on both sides of the sizing roll 11 in the width direction, only one side will be described below.

The receiving member 50 includes a guiding member 51 as a receiving part for receiving the size liquid S overflowing from the size liquid reservoir 18 and flowing the size liquid S to the outside of the sizing tank 3, and a mounting member 52 for mounting the guiding member 51. It consists of The guide member 51 is composed of a flowing portion 51a for receiving and flowing the size liquid S overflowing from the size reservoir 18 and a regulating portion 51b for regulating the flow of the size liquid S flowing on the flowing portion 51a.

More specifically, the flow portion 51a of the guide member 51 is a thin plate, and is formed to have a substantially rectangular shape when viewed in the plate thickness direction. Specifically, the flow portion 51a has a shape in which one of two corners on one end side in the long side direction of the end face is chamfered. In other words, the flow portion 51a includes the chamfered portion (chamfered portion) 51a2 and a rectangular portion (rectangular portion) 51a1 excluding the chamfered portion 51a2 in the long side direction. Incidentally, the rectangular portion 51a1 of the flowing portion 51a is formed in such a manner that the portion on the side of the chamfered portion 51a2 in the long side direction is slightly bent in the plate thickness direction.

The restricting portion 51b has a plate shape having the same plate thickness as that of the flowing portion 51a, and is continuous with one chamfered edge of both edges parallel to the long-side direction of the flowing portion 51a. It is made up of shapes. However, the restricting portion 51b exists over the entire existing range of the one edge of the flow portion 51a and is formed so as to be perpendicular to the end surface of the flow portion 51a. Therefore, the restricting portion 51b has a portion continuous with the rectangular portion 51a1 of the flow portion 51a and an inclined portion formed so as to be continuous with the chamfered portion 51a2 so as to form an angle (the same angle as the chamfered portion) with respect to that portion. portion 51b1.

As for the mounting member 52, the mounting member 52 is a plate-like member, and has a through hole at one end thereof through which a mounting screw member is inserted. have holes. In this embodiment, the portion to which the receiving member 50 (mounting member 52) is attached is the lateral wall 43 of the collection box 40. As shown in FIG. In the receiving member 50, the guiding member 51 is joined to the mounting member 52 by welding or the like.

The guide member 51 and the attachment member 52 are joined so that the end surface of the flow portion 51a and the end surface of the attachment member 52 are perpendicular to each other. Furthermore, the joining is performed with the mounting member 52 mounted on the lateral wall 43 of the collection box 40 (mounted state) as described later, and the end surface of the flow portion 51a of the guide member 51 is inclined in the vertical direction (from the rear side). It is done in such a way that it is in a state of being inclined downwards toward the front. In this embodiment, the guide member 51 and the mounting member 52 are defined by the other edge of the flow portion 51a of the guide member 51 (the edge opposite to the one edge) and the other end of the mounting member 52. It is joined so that the side edges are aligned. Therefore, the edge of the mounting member 52 on the other end side is formed along the end surface of the flow portion 51a, which is inclined in the mounting state, when viewed in the plate thickness direction of the mounting member 52 (FIG. 4). It is

In the receiving member 50 configured in this manner, the screw member inserted through the through-hole of the mounting member 52 is screwed into the female screw hole formed in the lateral wall 43 of the collection box 40. It is attached to the lateral wall 43 of the collection box 40 . Regarding the mounting position of the receiving member 50 , the receiving member 50 is such that the lower end of the guiding member 51 (flowing portion 51 a ) inclined as described above is aligned with the upper edge of the side wall 7 of the gluing tank 3 . It is mounted slightly above the

In addition, with respect to the front-rear direction, the receiving member 50, in the attached state, has the flow portion 51a of the guide member 51 between the support shaft 12 supporting the sizing roll 11 and the support shaft 14 supporting the first squeeze roll 13. It is in a state of being provided so as to exist throughout. In other words, the flow portion 51a of the guide member 51 in the receiving member 50 is sized in the long side direction so that it can exist between the support shafts 12 and 14 in the front-rear direction in the inclined state as described above. have. Therefore, the receiving member 50 is provided in such a manner that the existing range of the flowing portion 51a includes the existing range of the size pool 18 in the front-rear direction. Further, in the state in which the receiving member 50 is provided in this way, the size reservoir 18 and the receiving member 50 are arranged so that the existence range of the rectangular portion 51a1 of the flowing portion 51a is the same as the existence range of the size reservoir 18 in the front-rear direction. The positional relationship is such that they are included.

In addition, the dimension in the short side direction of the rectangular portion 51a1 in the flowing portion 51a is larger than the interval between the lateral wall 43 of the collection box 40 and the side wall 7 of the gluing tank 3 facing each other in the width direction, and The size is slightly smaller than the interval between the lateral wall 43 of the box 40 and the sizing roll 11 (first squeeze roll 13). Therefore, in the attached state, the receiving member 50 exists such that a portion of the end face of the flowing portion 51a overlaps the glue reservoir 3 in the width direction in the range of existence of the glue reservoir 18 in the front-rear direction. there is

Since the flow portion 51a is chamfered at one end in the long side direction as described above, the chamfered portion 51a2 has a shape such that the dimension in the short side direction gradually decreases. ing. In addition, the chamfering of the flowing portion 51a is slightly outside the side wall 7 of the gluing tank 3 (the side wall 43 of the collection box 40) from the one edge in the width direction in the mounting state of the receiving member 50. The flow portion 51a is formed in such a manner that it is notched up to the position where the Therefore, in the regulating portion 51b continuing to the flowing portion 51a, the inclined portion 51b1 continuing to the chamfered portion 51a2 is positioned outside the glue tank 3 in the width direction. there is

According to the warp sizing apparatus 1 of the present embodiment configured as described above, the size liquid S is supplied from the supply nozzle 24 to the size liquid pool 18 in the wedge-shaped region 17, and the size liquid S is supplied to the size liquid pool 18. The size liquid S overflows to both sides of the sizing roll 11 and the first squeeze roll 13, but since the receiving member 50 is provided as described above, the receiving member 50 can absorb the overflowing size liquid S. Since it is received and guided to the outside of the sizing tank 3 in the width direction, the sizing liquid S overflowing from the sizing liquid reservoir 18 is prevented from falling into the sizing tank 3 (mixing into the size liquid in the sizing tank 3). be Some of the size liquid S overflowing from the size liquid pool 18 hits the side wall 43 of the collection box 40 and bounces back toward the gluing tank 3 . to prevent it from falling.

More specifically, the flow portion 51a of the guide member 51 in the receiving member 50 is, as described above, in the range of presence of the size liquid pool 18 in the front-rear direction, in the width direction. A portion of the end face is present in such a manner as to overlap with the gluing tank 3. - 特許庁Therefore, the size liquid S falling from above is received by the flowing portion 51a. In addition to the flowing portion 51a, the guiding member 51 also has a regulating portion 51b facing the side wall 43 of the collection box 40, so that the paste liquid S bouncing off the side wall 43 as described above is more effective. It is designed to be received by

Since the guide member 51 is provided in an inclined state as described above, the size liquid S received by the guide member 51 flows downward along the end surface of the flowing portion 51a. In addition, the restricting portion 51b is formed to be perpendicular to the end surface of the flowing portion 51a through which the size liquid S flows. Therefore, overflow of the size liquid S flowing on the flowing portion 51 a to the side of the size tank 3 is restricted by the regulation portion 51 b , so that the flowing size liquid S does not flow into the size tank 3 .

In addition, the regulating portion 51b of the guide member 51 has an inclined portion 51b1 forming an angle with respect to the direction in which the size liquid S flows at the position of the chamfered portion 51a2 which is the lower end side of the flowing portion 51a with respect to the long side direction. The tip of the inclined portion 51b1 is positioned outside the gluing tank 3 in the width direction. As a result, the sizing liquid S flowing through the flowing portion 51a hits the inclined portion 51b1 and is guided to the outside of the sizing tank 3 (recovery box 40). Therefore, the size liquid S received by the flow portion 51a is flowed downward along the end surface of the flow portion 51a, and is guided by the regulation portion 51b to the collection box 40. As shown in FIG.

As described above, in the receiving member 50 configured as described above, the end surface of the flowing portion 51a functions as an inclined surface for flowing the size liquid S from the size liquid pool 18 downward from above. In addition, the inner end surface of the restricting portion 51b of the guide member 51 functions as a restricting surface that restricts the size liquid S flowing on the inclined surface (the end surface of the flowing portion 51a) from flowing down into the size tub 3. Furthermore, in the restricting portion 51 b of the guide member 51 , the inner end surface of the inclined portion 51 b 1 functions as a guide surface that directs the flow of the size liquid S to the outside of the size tub 3 .

As described above, according to the warp sizing apparatus 1 of the present embodiment, the size liquid S overflowing from the size liquid pool 18 formed in the wedge-shaped area 17 is received by the receiving member 50 and flows to the outside of the sizing tank 3. Therefore, it is possible to prevent foreign substances such as warp fluff and fluff from being mixed in the size liquid S in the size liquid in the sizing tank 3 as much as possible. As a result, the amount of foreign matter mixed in the size liquid S of the gluing tank 3 is reduced compared with the conventional one, so that the problem that the foreign matter mixed in the size liquid S of the gluing tank 3 is not discharged as expected is less likely to occur. As a result, deterioration of the state of the sizing liquid in the sizing tank 3 is suppressed.

Furthermore, if the receiving member 50 is configured as a separate member from the sizing tank 3 and the collection box 40 as in the case of the present embodiment, the receiving member 50 can also be used for the existing warp sizing device. can be applied as an afterthought.

However, the receiving member 60 has side wall portions 62 formed so as to rise from both long side edges of the plate-like portion 61 . In addition, the plate-like portion 61 of the receiving member 60 has a size larger in the short side direction than the size in the front-rear direction of the existence range of the paste pool 18 . The receiving member 60 is positioned such that the short side direction of the plate-like portion 61 coincides with the front-rear direction, and the range of existence of the plate-like portion 61 includes the range of existence of the size reservoir 18 in the front-rear direction. is provided in Incidentally, the receiving member 60 is provided at such a position via a mounting member (not shown) or the like.

In addition, the receiving member 60 has one end edge on the side of the sizing roll 11 in the long side direction of the plate-like portion 61, and the other end edge on the side of the lateral wall 43 of the collection box 40 (outside in the width direction). It is provided in an inclined state so as to be positioned higher than.
