555910 V. Description of the invention (4) " The density of the weft yarn of the weaving cloth 18 can be adjusted by controlling the rotation of the surface roller 26 and the feeding speed of the weaving cloth 18. The suction pipe, that is, the dewatering pipe 20, is formed by using a cylindrical pipe body 32, and extends in the width direction of the woven fabric 18 (the direction perpendicular to the paper surface in the i-th figure). A state in which it is supported on a frame (not shown) and cannot be rotated. The dewatering pipe 20 has a slit-shaped suction opening 34 extending continuously in the width direction of the woven fabric in the winding area where the woven fabric 18 is wound, and in the winding area, the axis of the dewatering pipe 20 is maintained. At equal angular intervals, there are a plurality of groove-shaped recesses 36 extending continuously in the width direction of the fabric. Among the plurality of recessed portions, the first recessed portion 3 6 a located on the most upstream side in the moving direction of the woven fabric is formed near the upstream end of the winding area, and is therefore located more upstream than the space portion of the winding area. 'The suction port 34 is a slot (s 10) that penetrates the water removal pipe 20 in the thickness direction, and is the first one located on the most upstream side toward the inside of the water removal pipe 20 and the moving direction of the weave The recess 36a is open. The internal space except the water pipe 20 is hermetically closed except for the portion of the suction port 34. Each recessed portion 36 has a peripheral surface lower than that of the water pipe 20. In addition to the water pipe 20, the water removal device 10 also has an air-water separation device that communicates with the water removal pipe 20, and a suction device that discharges through the gas-water separation device, that is, the air in the water removal pipe 20 (both (Not shown). The gas-water separation device may be a conventional device for separating water in the air passing therethrough from the air. The suction device may have a conventional suction device such as an electric fan or an air pump for sucking air.

555910 V. Description of the invention (5) When entering the weaving cloth, the weaving cloth 18 is moved while touching the winding area μ of the water removal pipe 20, and then wound around the winding roller 24. However, due to the water removal I is that recesses 36 are continuously formed on the outer peripheral surface of the pipe body member 32 without forming corners, so that touch defects caused by the presence of the recesses 36 can be prevented. Female In addition, while the cloth 18 is moving, the air in the water removal pipe 20 can be exhausted by suction. Therefore, the weaving area corresponding to the first recessed portion 36a will be sucked into the drain pipe 20 through the first recessed 36-stage suction port 34. As a result, the moisture contained in the woven fabric 18 can be sucked into the water removal pipe 20 together with the air sucked to the suction port 4 and removed from the woven fabric 18. «In the water-breaking device, the recess 36 of the outer peripheral surface of the water removal pipe 20 is the same as that of the water removal pipe 2 0 18—the winding area on the outer peripheral surface of the water removal pipe 20 forms a plurality of water removal pipes 20 and woven fabric 18 Spaces 3 8. Therefore, as shown in FIG. 2, the amount of air sucked from the suction opening 34 is the total in one air: the yarn passing through the weaving area facing the 5 denier solid space 38 a formed by the first recess 3 The space between the fibers or fibers ^ w enters the first: solid space 38b from the uppermost side through the yarn space or fiber between the second: = 38b of the weaving area facing the first: 38b, Then, from the second space 38b, the amount of air between the yarns or fibers of the mesh :: weaving: except the water pipe 20; and the weaving from the weaving = 8 to the upstream end of the winding area and the weaving Cloth 18 and other than the water pipe 2〇 ::: formation room, and pass through the water pipe 2. The amount of air between woven fabrics on the outer peripheral surface or between yarns or fibers. From the above, it can be seen that, when the drain pipe 20 is used, compared with the case where the recess 36 is not provided,

Page 9 555910 V. Description of the invention (6) ~~ In the residual water pipe, the pipe 20 can add the amount of suction air from the suction port 34, so the amount of water drawn in the dewatering & taxi team will be related to the air At the same time, it can increase more, which can improve the water removal capacity and water removal efficiency.忐 右 喁 ^ 水 器 1〇 中 'is a continuous shape extending in the width direction of the weave ^ The mouth 34 and the recess 3 6 a on the most upstream side, the weave 18 can uniformly remove water in the direction of the weaving. Since each of the recesses 36 continuously extends in the width direction of the woven fabric, it is possible to form a rib with a U-shaped cross section extending in the longitudinal direction. Therefore, although the water removal pipe 20 has a reduced rigidity due to the slit-shaped suction port 34, it can be reinforced to increase the rigidity. In the example shown in the figure, each of the recessed portions 36 is made by abutting the pipe member 32 having a circular cross-sectional shape against the casting mold, and then pulled out toward the long side, so that the portion corresponding to the recessed portion 36 faces the thickness direction. Deformed and formed below the outer peripheral surface. Therefore, the original thickness of the pipe body member 32 can be maintained to form a recessed portion 36 °. Both ends of each recessed portion 36 can be opened toward the side of the end face of the water removal pipe 20, and can also be in a closed state. However, as shown in FIG. 2, if both ends of one or more recesses 3 6 c to 3 6 η formed for improving rigidity and located on the downstream side without affecting water removal ability are opened, air will pass through these recesses. In 3 6 c to 3 6 η, the woven fabric i 8 can contact the air passing through the recesses 36 c to 36 η and become dry compared to the case where both ends of the recesses 3 6 c to 3 6 η are locked. fresh. In the embodiments shown in Figs. 1 and 2, the suction port may be opened so as not to face the recessed portion 36a. In this case, the water removal pipe may not have a recess

Description of the invention (7) 36a, it is also possible to make the suction opening 34 facing = less + make the recess 363 more upstream than ° and 5 丨 D 34, and 4 facing adjacent 3 of the recesses are open. w to form a plurality of attracts:,:, In the intermittent example of the weaving direction of the cloth, make the attraction 0 Bu also face the second and subsequent ηπ in the real and bow 1 34 shown in Figs. 1 and 2. It can only be used to replace the retaining door in the circumferential direction of the water removal pipe. Secondly, a plurality of recesses are continuously formed in the direction of the width of the weaving. The recesses are formed near the suction mouth of the total water removal armour—or t 5 may be further downstream than the suction mouth. It is said that the space is defined by the convex portion instead of the concave A fabric. W ° 卩 is formed by the water removal pipe and the effect according to FIG. 3, the water removal pipe 50 is a suction tooth ^ member with # 古 52 on the peripheral surface of the pipe body member 32, that is, the rod-shaped member is oriented in the direction of the knitting width. Extended status. In the rod-shaped position, the mounting member is formed of a member 52 having a hemispherical cross-sectional shape as shown in the figure, and is formed on a material corresponding to a curved convex surface, 32.妁 The bottom surface is welded and joined to the pipe body member. In the drain pipe 50, the woven fabric 18 is positioned, and is wound after passing through the upstream side portion 5 2 of the suction port 34 and the mouth 34 of the rod-shaped member 52 and then wound. 'The convex surface and the rod-shaped member water pipe 50 and the woven fabric 18 are formed with the suction port q and the rod-shaped member 52 has the upstream side space 54 and the space 54 and 56 has the same effect as that of ★★ 02 and 36η, respectively. Therefore, according to the same function and effect of the concave portion 361) and the 36c pipe 20, the water removal pipe ^ can obtain the water removal pipe Γ.

555910 V. Description of the invention (8) ^ The rod-shaped member 5 2 is provided to extend in the direction of the long side, and the rigidity of the water removal pipe 50 can be further improved. Referring to Fig. 4, the water removal pipe 60 is a plurality of recessed portions 62 held in a spaced direction toward the width direction of the fabric at a position downstream of the i inlet 34 of the pipe body member 32. The water removal pipe 60 can be obtained by forming a circular recessed portion 62 having the same size on the drill member 32. θ In the water removal pipe 60, the suction port 34 may be opened toward the outer peripheral surface of the water removal pipe 60 without facing the recess. However, since the suction port 34 and the recessed portion 62 are closed by the woven fabric, the recessed portion 62 facing the weaving interval will perform the same function as the recessed portion 36b on the middle downstream side in FIG. I and FIG. The bitter effect can also be obtained to improve the water-removing ability. The concave portion or the convex portion may be located on at least one of the upstream side and the downstream side of the woven fabric with respect to the suction opening. Further, it may have one or more portions extending continuously in the width direction of the woven fabric, or may have a plurality of portions intermittently juxtaposed in the width direction of the woven fabric.
