Description

  The present invention relates to a rubbing cloth for producing a liquid crystal panel, and also relates to a method for producing the rubbing cloth. Furthermore, the present invention relates to a scissors for weaving a rubbing cloth suitable for weaving the rubbing cloth.

  In the manufacturing process of the liquid crystal panel, rubbing treatment is performed to align liquid crystal molecules in a desired direction.

  The rubbing process is a rubbing roll in which a surface of an alignment film made of polyimide resin or the like formed on a substrate holding a liquid crystal is wound around a circumferential surface of a rotating roller with a rubbing cloth woven with pile yarn. Is a process of forming a fine groove along the rotating direction by rubbing in a rotating state.

  As described above, the rubbing cloth used for forming the rubbing roll is used by being wound around the outer peripheral surface of the rotating roller. In order to improve the uniformity of the rubbing process, the rubbing roll rotating direction is used. It is preferable to incline the pile yarn in advance. As a means for that purpose, registered utility model No. 3032820 proposes a rubbing cloth in which a pile yarn is inclined at a predetermined angle in the length direction of the warp yarn of the ground structure.

  By the way, in recent years, the size of liquid crystal panels has been increasing, and accordingly, a rubbing roll having a longer length has been demanded. In order to form a rubbing roll having a large length, a wide rubbing cloth having pile yarns inclined along the rotation direction of the rubbing roll is required. In this case, a rubbing cloth having a large weaving width is required when a rubbing roll having a desired length is formed by winding the warp yarn in the direction of the rotation of the rotating roller. However, weaving a rubbing cloth having a large weaving width has a problem that the weaving machine has a structural limit and cannot be handled.

  Thus, rubbing cloths in which pile yarns are inclined at a required angle in the length direction of the wefts of the ground texture have been proposed in Japanese Patent Laid-Open Nos. 2002-148628 and 2006-241638. When the rubbing cloth having such a configuration is used, the outer circumference of the rotating roller is set so that the length direction of the weft is directed to the rotating direction of the rotating roller and the length direction of the warp is directed to the axial direction of the rotating roller. When wound on the surface, a long rubbing roll in which the pile yarn was inclined along the rotation direction of the rotating roller could be formed.

  FIG. 20 is an explanatory diagram for explaining a method for manufacturing a rubbing cloth disclosed in Japanese Patent Application Laid-Open No. 2002-148628. In the manufacturing method, first, a brush-like rotating belt a provided with a plurality of needle-shaped stainless steel wires on a surface thereof is rotated so that the stainless steel wires brush (pick) the pile yarn. The pile yarn is inclined in the length direction of the weft yarn. After that, shape stabilization processing is performed to maintain the inclined state of the pile yarn. This is because the inclined state of the pile yarn is maintained by curing the impregnating resin, or the pile yarn is formed using a synthetic fiber such as polyester. In some cases, a dry heat setting process or the like was applied to maintain the inclined state of the pile yarn.

  However, the processing for inclining the pile in the weft direction by such form-stabilizing processing is merely to post-treat the pile yarn on the ground fabric in which the pile yarn is woven in an upright state, It is only forcibly bending elastically deformed into an inclined state against the elastic force, and the inclined state is held by shape stabilization processing. Therefore, the inclined state of the pile yarn is returned by the elastic force of the pile yarn. It tended to be easy. For this reason, there is a problem that the inclination direction of the pile yarn is likely to be uneven, and there is a problem that the inclination state of the pile yarn is likely to be unstable. In particular, when the pile yarn is non-synthetic fiber such as cotton yarn, the pile could not be stably processed in an inclined state by the dry heat setting process.

  In addition, as shown in FIG. 21, the rubbing cloth disclosed in Japanese Patent Application Laid-Open No. 2006-241638 is composed of a pile warp b woven upright in the ground structure in a weaving process, consisting of a thick warp c and a thin warp d. According to the difference in thickness, the weft e is pushed down in the lengthwise direction in the length direction, but it cannot always be tilted in a uniform state, and the pile yarn b is inclined by the elastic force of the pile yarn b. The condition tended to return easily.

  Further, in the conventional rubbing cloth in which the pile yarn is held in an inclined state by post-processing such as brushing or warps having different finenesses, a pile yarn having a short protrusion length (for example, a protrusion of about 1.0 to 1.3 mm) is used. Even if it is intended to bend and deform a desired length of slant), it is difficult to bend and deform due to the elastic force of the pile yarn.

  The present invention was developed in view of the above-mentioned conventional problems, and the pile yarn is uniform in the length direction of the weft of the ground structure without relying on an unstable processing step such as brushing or resin processing. Another object of the present invention is to provide a rubbing cloth that is inclined in a stable state and has excellent durability.

  Another object of the present invention is to provide a method for producing a rubbing cloth capable of efficiently mass-producing a rubbing cloth having excellent durability by being inclined in a uniform and stable state in the longitudinal direction of the weft yarn of the texture. It is.

That is, the rubbing cloth according to the present invention is a rubbing cloth composed of a ground structure woven by warps and wefts and a number of pile threads protruding in an inclined state on the surface of the ground structure, The ground structure is woven in a weaving process so as to be in a protruding state that is locked to the weft and that is inclined at the same angle in the same direction when viewed in the length direction of the weft, and in the inclined protruding state The root portion of the pile yarn is held between adjacent warps.

  A method for producing a rubbing cloth according to the present invention is a method for producing a rubbing cloth comprising a ground structure woven by warps and wefts, and a plurality of inclined pile yarns protruding from the surface of the ground structure. The pile yarn is woven into the ground structure so that the pile yarn is locked to the weft yarn and is inclined at the same angle in the same direction when viewed in the length direction of the weft yarn. The root portion of the yarn is held by adjacent warps.

  One of the specific embodiments of the method for producing a rubbing cloth according to the present invention is that the lower ground warp and the upper ground warp and the pile warp which weave the upper and lower ground structures are viewed in the same direction when viewed in the extending direction of the weft. The lower ground warp, the upper ground warp and the pile warp are moved up and down in the tilt direction of the inclined gap. And weaving the lower ground structure by crossing the lower ground warp and lower weft, and weaving the upper ground structure by crossing the upper ground warp and upper weft, The pile warp is woven into the upper and lower ground structures so as to connect the ground structures with pile warps, and then, the pile warp connecting the upper and lower ground structures is cut at the upper and lower intermediate portions. Is.

  Other than the specific embodiment of the method for producing a rubbing cloth according to the present invention, the lower ground warp and the upper ground warp and the pile warp knitting the upper and lower ground structures are viewed in the same direction when viewed in the extending direction of the weft. The lower ground structure is woven by crossing the lower ground warp and the lower weft through the inclined gap formed between the required wings of the wings inclined at the same angle, and the upper ground The upper ground structure is woven by the intersection of the warp and the upper weft, and the pile warp is composed of the first lower weft and the second lower structure that are arranged side by side in the weaving direction. The first upper weft, the second upper weft, and the third upper weft, which are sequentially weaved into the weft and the third lower weft, and are arranged side by side in the weaving direction. Weaving sequentially, repeating this in the weaving direction, connecting the upper and lower ground structures with pile warp, then The pile warp for connecting the upper and lower ground structure, a manufacturing method of the rubbing cloth to be cut at its upper and lower middle portion. The pile warp passes under the first lower weft and is guided upward in the inclined gap, and then passes over the second lower weft and then the inclined gap. Is guided in the downward direction, and after passing under the third lower weft, is guided in the upward direction through the inclined gap, and then is passed over the first upper weft. Guided downward in the inclined gap, then after passing under the second upper weft, guided upward in the inclined gap, and then over the third upper weft After that, the inclined gap is guided downward, and after passing under the first lower weft different from the third lower weft, the inclined gap is guided upward. It is characterized by that.

  Other than the specific embodiment of the manufacturing method of the rubbing cloth according to the present invention, the lower ground warp and the upper ground warp and the pile warp that weave the upper and lower ground structures are viewed in the same direction as viewed in the extending direction of the weft. The lower ground structure is woven by crossing the lower ground warp and the lower weft through the inclined gap formed between the required wings of the wings inclined at the same angle, and the upper ground The upper base structure is woven by the intersection of the warp and the upper weft, and after passing through the lower weft, the pile warp is guided upward through the inclined gap, and then on the upper weft. After that, the inclined gap is guided downward, and then passes under a lower weft different from the lower weft, and is guided upward through the inclined gap. After passing over the upper weft, which is different from the weft, it is guided downward through the inclined gap. Ri between the upper and lower ground weave connected by pile warp by returning, then the pile warp for connecting the upper and lower ground structure, is characterized in that the cutting at the upper and lower middle portion.

  In the rubbing cloth, it is preferable that adjacent warp yarns holding the root portion of the pile yarn in an inclined protruding state are set to the same fineness.

  In the manufacturing method of the rubbing cloth, it is preferable that adjacent warp yarns holding the root portion of the pile yarn in an inclined protruding state are set to the same fineness.

  In the kite for manufacturing a rubbing cloth according to the present invention, each kite is inclined at the same angle in the same direction when viewed in the weft direction, and an inclined gap for passing the yarn is formed between adjacent kites. It is characterized by that. Each wing is preferably inclined at an angle of 5 to 30 degrees.

The present invention has the following excellent effects.
(1) The rubbing cloth according to the present invention is used in the weaving process so that the pile yarn is locked to the weft of the ground structure and is in a protruding state inclined at the same angle in the same direction when viewed in the length direction of the weft The root portion of the pile yarn that is woven and is in an inclined protruding state is held between adjacent warps.

  Therefore, when the rubbing cloth according to the present invention is used, the pile yarn is inclined at the same angle in the same direction when viewed in the length direction of the weft, so that the long yarn is not only a conventional short rotating roller. Also on the rotating roller, the rubbing cloth can be wound around the outer peripheral surface so that the pile yarn is inclined along the rotating direction of the rotating roller, and the request for lengthening the rubbing roll, that is, the liquid crystal panel In addition to being able to meet the demand for larger size, there are the following special effects.

  That is, in the rubbing cloth according to the present invention, the pile yarn is woven in an inclined protruding state in the weaving process. Therefore, the pile yarn woven upright in the ground structure is forcibly bent and elastically deformed against the elastic force of the pile yarn, and the inclined state is held by post-processing such as resin processing. A conventional rubbing cloth, or a conventional rubbing cloth formed by holding a pile yarn woven upright in the ground structure between two types of warp yarns in an inclined state in the weft direction. On the other hand, the inclined state is natural and stable, and there is no fear that the inclined state becomes non-uniform or the pile yarn is easily returned to the inclined state by the elastic force of the pile yarn.

  In particular, when the inclined state of the pile yarn is held in a state of being sandwiched by warps of the same fineness, the pile yarn in the inclined state is loosened in a rubbing process using a rubbing roll formed by winding the rubbing cloth around a rotating roller. It is difficult and excellent in durability. Therefore, it is possible to provide a rubbing roll capable of producing a high quality liquid crystal panel with a high yield.

(2) As a method for producing a rubbing cloth according to the present invention, warp yarns and pile warp yarns are formed in the inclined gaps formed between the required wings of the wings inclined at the same angle in the same direction when viewed in the length direction of the wefts. When the configuration in which the warp and the pile warp are moved up and down through the inclined gap is adopted, the pile warp can be uniformly inclined in the length direction of the weft in the weaving process, and this is woven. The root portion of the pile yarn in the inclined state can be securely held and held by the adjacent warp yarns. Therefore, when the production method of the present invention is used, the high-quality rubbing cloth having a pile yarn that is uniformly inclined and has a stable inclined state can be efficiently obtained without requiring post-treatment as in the prior art. It can be mass-produced.

  Further, in the conventional rubbing cloth in which the pile yarn is held in an inclined state by post-processing such as brushing or warps having different finenesses, a pile yarn having a short protrusion length (for example, a protrusion of about 1.0 to 1.3 mm) is used. Although it was difficult to bend and deform due to the action of the elastic force of the pile yarn, it was difficult to bend and deform the long one) to the required inclined state. Even in such a pile yarn having a short protruding length, it is possible to provide a rubbing cloth in which the pile yarn is protruded uniformly in a stable state in a required inclined state.

(3) The scissors according to the present invention are suitable for use in carrying out the method for producing a rubbing cloth.

  FIG. 1 is a perspective view for explaining a rubbing cloth 1 according to the present invention and a schematic view for explaining a woven structure. A ground structure 5 woven by warps 2 and wefts 3 and a surface 6 of the ground structure 5 are shown. It has a raised layer 9 composed of a plurality of cut pile yarns 7 protruding. As shown in FIGS. 1 to 3, the pile yarn 7 is locked while being hooked on the weft 3 and is inclined at the same angle θ1 (FIG. 3) in the same direction when viewed in the length direction of the weft 3. The pile structure 7 is woven in the weaving process so as to be in a protruding state, and the pile yarn 7 has a woven structure inclined from its root. As shown in FIG. 3, the root portion 10 of the pile yarn 7 in an inclined protruding state is firmly held by the adjacent warp yarns 2 and 2 having the same fineness (thickness). For this reason, the pile yarn 7 is already provided with an inclined ridge that is uniformly inclined at the same angle in the same direction as seen in the longitudinal direction of the weft 3 in the woven state, and the inclined protruding state is It is stably held by the adjacent warps 2 and 2 having the same fineness.

  The ground structure 5 is not particularly limited as long as it can weave a pile, and for example, a plain texture by warp 2 and weft 3 or a woven structure such as twill weave or satin weave can be used. As the weft 3, the warp 2 and the pile yarn 7, in the case of a long fiber, for example, a 30-150 denier rayon fiber yarn can be used. In the case of spun yarns, for example, cotton yarns with 40 yarn counts, cotton yarns with 60 yarns, and cotton yarns with 80 yarns can be used. In addition, various long fiber yarns and short fiber yarns can be used as long as the rubbing treatment is not hindered. Further, the warp yarn 2, the weft yarn 3, and the pile yarn 7 may have different materials as long as they do not hinder the rubbing process.

Moreover, the warp density of the manufactured rubbing cloth 1 is set to, for example, 18 to 30 yarns / cm, the weft density is set to, for example, 30 to 45 yarns / cm, and the number of pile yarns 7 per unit area is, for example, 270 to Set to 300 / cm ² . The pile yarn 7 is woven into the ground structure 5 in a W shape, for example, as shown in FIG. 1, or is formed into a V shape or a U shape (in FIGS. 4-5, for example) as shown in the schematic diagrams of the woven structure in FIGS. Can be woven into the ground structure 5 in a V shape.

  The length of the pile yarn 7 can be set to, for example, 1.8 to 3.5 mm, preferably 2.0 to 2.5 mm. Further, the inclination angle (indicated by θ1 in FIG. 3) of the axis 11 of the pile yarn 7 with respect to the perpendicular 8 perpendicular to the plane of the ground structure 5 is set as required in consideration of various conditions of rubbing treatment. And can be set to 5 to 30 degrees, preferably 10 to 15 degrees.

A specific example will be described. The ground structure 5 has a warp density of 24 / cm using a 100 denier rayon fiber yarn as the warp yarn 2 and a 100 denier rayon fiber yarn as the weft yarn 3. Woven in a plain weave with a weft density of 40 / cm. Further, a 100 denier rayon fiber yarn is used as the pile yarn 7, and the number of pile yarns 7 per unit area is 640 pieces / cm ² by a known loom such as a shuttle loom or a rapier loom. It is woven into the ground structure 5 in the W shape shown. The length of the pile yarn 7 is set to 1.8 mm, and the inclination angle θ1 of the axis 11 of the pile yarn 7 with respect to the perpendicular 8 perpendicular to the plane of the ground structure 5 is set to 10 degrees.

To describe another specific example, the ground structure 5 uses a spun yarn of 40 cotton counts made of cotton fibers as the warp yarn 2 and a cotton count spun yarn of cotton fibers as the weft 3 Using 40th yarn, it is woven into a plain weave with a warp density of 18 yarns / cm and a weft density of 30 yarns / cm. Also, as the pile yarn, a spun yarn of 40 count cotton yarn made of cotton fibers is used, and the number of pile yarn per unit area is 270 / cm ² , using a known loom such as a shuttle loom or rapier loom. For example, it is woven into the ground structure 5 in a V shape shown in FIGS. The length of the pile yarn 7 is set to 2.5 mm, and the inclination angle θ1 of the axis 11 of the pile yarn 7 with respect to the perpendicular 8 perpendicular to the plane of the ground structure 5 is set to 10 degrees.

  6 to 7 are organization charts showing other weaving states of the pile yarn 7 in the rubbing cloth 1 according to the present invention. FIG. 8 is a structure diagram showing another embodiment of the upper and lower ground structures 5 and 5 together with the pile yarn weaving state.

  In the present embodiment, the back surface 12 (FIG. 1 (A)) of the ground structure 5 is coated with a resin such as an acrylic emulsion to smooth the back surface. FIG. 9 shows the rubbing cloth 1 having such a configuration in which the length direction of the weft 3 is directed to the rotation direction of the rotating roller (for example, the roller length is 4 m) 13 and the length direction of the warp yarn 2 is the axis of the rotating roller. It is sectional drawing which shows the rubbing roll 16 wound around the outer peripheral surface 15 of this rotation roller 13 toward the direction. In this embodiment, since the back surface 12 of the ground texture 5 is smoothed as described above, the ease of winding and the improved stability of the winding state when the rubbing cloth 1 is wound around the outer peripheral surface 15 of the rotating roller 13 are improved. Is planned. FIG. 10 is an explanatory view showing a state in which the surface 17 of the alignment film is rubbed using the rubbing roll 16.

  In the manufacturing method for manufacturing the rubbing cloth 1 having such a configuration, the pile yarn 7 is engaged with the weft yarn 3 and is in a protruding state inclined at the same angle in the same direction when viewed in the length direction of the weft yarn 3. In this way, the base structure 5 is woven into the ground structure 5 and then the root portion 10 of the inclined pile yarn 7 is held between adjacent warps 2 and 2 having the same fineness (thickness).

  An example of the specific manufacturing method will be described in the case of manufacturing the rubbing cloth 1 shown in FIG. 1 in which the pile yarn 7 is a cut pile yarn.

  As shown in FIGS. 11 to 12 and 13, the basic configuration uses a ridge 21 in which an inclined gap 20 (FIG. 14) is formed between adjacent wings 19 and 19, and passes through the inclined gap 20. The lower ground warp 30, the upper ground warp 31, the lower weft 39, and the upper weft 40 are used to weave the upper and lower ground structures 5 a and 5 b with a predetermined interval therebetween. The pile warp 32 is woven into the upper and lower ground structures 5a and 5b so as to reciprocate between the upper and lower ground structures 5a and 5b, and then the pile warp is formed at an intermediate portion between the upper and lower ground structures 5a and 5b. 32 is cut with a cutter 22 during weaving. In this way, the rubbing cloth 1 in which the pile yarns 7 are woven into the upper and lower ground structures 6 and 6 so as to be inclined at the same angle in the same direction when viewed in the length direction of the weft 3 is manufactured. .

  Hereinafter, this manufacturing method will be specifically described. FIG. 14 is an enlarged view showing the reed 21. For example, the reed wings 19 having a vertical length of 105 mm, a width of 4 mm, and a thickness of 0.2 mm are separated by a weft of 0.57 mm, for example. The upper and lower ends 23 and 25 of each wing 19 are fixed to the upper and lower fixing plates 26 and 27 so as to incline at the same angle in the same direction when viewed in the length direction 3. The inclination angle θ2 of the wing 19 with respect to the vertical line 29 is set to 5 to 30 degrees, and is set to 10 degrees in the present embodiment, for example. As a result, the inclined gap 20 that is inclined at an angle of 10 degrees is formed between the adjacent wings 19 and 19. If the angle is less than 5 degrees, a clear inclination angle of the pile yarn cannot be obtained, and if it exceeds 30 degrees, the friction between the inclined wings and the yarn during weaving increases, and the yarn This is not preferable because troubles such as cutting are likely to occur, resulting in hindrance to stable weaving.

  Like the conventional scissors, the scissors 21 having such a configuration swing in the front-rear direction as indicated by arrows in FIG. As the heel 21 swings, the upper ground warp 30 and the lower ground warp 31 are opened by the vertical movement of the heald (not shown).

  FIG. 15 is an explanatory view showing a state in which ground warp and pile warp are passed through the inclined gap 20 so that the rubbing cloth 1 shown in FIG. 1 can be manufactured. In FIG. 15, the vertical length of the inclined gap 20 is set short for convenience of explanation.

Then, as shown in FIG. 13, the two lower ground warps 30, 30 are distinguished from the first lower ground warp 30a existing on the left side and the second lower ground warp yarn 30b existing on the right side. The warp yarns 31 and 31 on the book are distinguished from the first upper warp yarn 31a existing on the left side and the second upper warp yarn 31b existing on the right side. Further, the four pile warp yarns 32, 32, 32, 32 are sequentially arranged from left to right from the first pile warp yarn 32a, the second pile warp yarn 32b, the third pile warp yarn 32c, and the fourth pile yarn. It is distinguished from the warp 32d. Then, the thread insertion state and the vertical movement of each thread in the first inclined gap 20a and the second inclined gap 20b will be described as follows.

  In the left part of FIG. 15, the first lower ground warp 30a is passed through the lower part 33 of the first inclined gap 20a, and the first upper ground warp 31a is passed through the first inclined gap 20a. Pass through the upper part 35. The first lower ground warp yarn 30a moves up and down obliquely in the lower portion 33 as shown by an arrow F1 on the left side of FIG. Also, the first upper ground warp 31a moves up and down obliquely in the upper portion 35 as shown by an arrow F2 on the left side of FIG. Then, as shown in FIG. 15, the first pile warp yarn 32a and the second pile warp yarn 32b are directed rightward in this order with the first pile warp yarn 32a and the second pile warp yarn 32b being placed on the right side of the upper and lower ground warp yarns 31a, 30a. It passes through the first inclined gap 20a. The first pile warp 32a and the second pile warp 32b move obliquely up and down in a state that extends over substantially the entire length of the first inclined gap 20a as shown by arrows F3 and F4 on the left side of FIG. To do.

  15, the second lower ground warp yarn 30b is passed through the lower portion 36 of the second inclined gap 20b, and the second upper ground warp yarn 31b is passed through the first inclined gap. Pass through the upper portion 37 of 20a. The second lower ground warp yarn 30b moves up and down diagonally at the lower portion 36 as shown by the arrow F5 in the right portion of FIG. Further, the second upper ground warp 31b moves up and down obliquely in the upper portion 37 as indicated by an arrow F6 in the right portion of FIG. Then, the third pile warp yarn 32b and the fourth pile warp yarn 32d are placed rightward of the ground warp yarns 31b, 30b positioned above and below, and the second inclined gap 20b is directed in this order with the third pile warp yarn 32d facing rightward. Pass through. The third pile warp 32c and the fourth pile warp 32d move up and down diagonally over the substantially entire length of the second inclined gap 20b as shown by arrows F7 and F8 on the right side of FIG. To do.

  The insertion state of each thread in the first inclined gap 20a and the second inclined gap 20b, the required striking movement of the reed 21, the opening movement of the upper ground warp, the lower ground warp, and the required weft As shown in FIG. 13, the lower ground texture 5 b is woven by the intersection of the first and second lower ground warps 30 a and 30 b and the lower weft 39, and the first and second The upper ground structure 5a is woven by the intersection of the upper ground warps 31a and 31b and the upper weft 40.

  The pile warp 32 is woven into the upper and lower ground structures 5a and 5b in a W shape as shown in FIG. 13, for example, if the first pile warp 32a is representatively described. More specifically, as shown in FIG. 16, after passing under the first lower weft 39a between adjacent lower ground warps 30a, 30b, the first inclined gap 20a is guided in the upward direction, and then over the second lower weft 39b adjacent to the first lower weft 39a, and then guided downward in the first inclined gap 20a. After passing under the third lower weft 39c adjacent to the second lower weft 39b, it is guided upward through the first inclined gap 20a, and then the first upper weft 40a. After being guided downward in the first inclined gap 20a, and then passing under the upper weft 40b adjacent to the first upper weft 40a, the first inclined gap 20a is guided upward, and then the second upper weft 4 adjacent to the first upper weft 40b. After passing over c, the first inclined gap 20a is guided downward, and then the third lower weft 39c, which is different from the third lower weft 39c, is the fourth from the third lower weft 39c. After passing under the first lower weft 39a, it is guided upward through the first inclined gap 20a, and then the second lower weft 39b adjacent to the first lower weft 39a. After passing over, the first inclined gap 20a is guided downward, and then passes under the third lower weft 39c adjacent to the second lower weft 39b, and then the second The first upper weft 40a is guided over the fourth upper weft 40a, which is different from the third upper weft 40c. After the crossing, the pile warp 32a is guided by being guided downward through the first inclined gap 20a and repeated. Upper and lower ground structure 5a, sequentially woven into 5b, and below the ground structure 5a, inter 5b is a state of being connected with the pile warp 32a.

  Thereafter, during weaving, the pile warp 32 connecting the upper and lower ground structures 5a and 5b is cut by the cutter 22 that reciprocates in the weft direction at the upper and lower intermediate portions (the central portion in FIG. 11). . As a result, as shown in FIG. 11, two upper and lower rubbing cloths 1 and 1 having pile yarns 7 that are slanted and locked to the wefts of the ground texture are manufactured. The upper and lower rubbing cloths 1 and 1 are wound around a beam (not shown).
