Take-up device for woven fabric with rubber

Abstract

A take-up device (1) for a woven fabric (W) with rubber comprises a rotating shaft (2), and a plurality of take-up boxes (3) mounted to the rotating shaft (2). The take-up boxes (3) are rotatable with respect to the rotating shaft (2). When a coupling key (4) is inserted into an insertion opening (2a) of the rotating shaft and an insertion opening (3a) of the take-up box (3) so as to span the insertion openings (2a, 3a), and another coupling key (4) is inserted so as to span the insertion openings (3a) of the adjacent take-up boxes (3), the take-up boxes (3) are locked with respect to the rotating shaft (2). By integral rotation of the rotating shaft (2) and the take-up boxes (3), each one of a plurality of woven fabrics (W) with rubber is simultaneously wound around each of the take-up boxes (3). After the coupling key (4) is taken out of the insertion openings (2a, 3a), the woven fabric (W) with rubber is unwound from the take-up box (3) by the rotation of the take-up box (3) with respect to the rotating shaft (2).

Description

technical field [0001] The present invention relates to a winding device for a rubberized fabric used when producing a rubberized fabric used as a tire material. Background technique [0002] When manufacturing tires, belt-shaped fiber belts (Jointless belts: hereinafter referred to as "JLB") of various sizes are used. These JLBs are generally produced through the following process: For a tire with a width of about 1500mm Coil the rubber fabric to form a rubber cord, place the rubber cord on the coiler and cut it into a width of about 80-100mm to form a rough cutting process of the JLB base material (Cameron Slitter process); and the JLB base material A fine cutting process (JLB Slitter process) in which the material is cut into a width of about 10 mm (Patent Document 1). [0003] image 3 It is a perspective view schematically showing main parts of a conventional JLB base metal coiling device, such as image 3 As shown, the winding device 1 includes a rotating shaft 2 and ...

AI Technical Summary

Problems solved by technology

For example, for a JLB base material with a width of 80mm, the winding length is limited to about 300m (with a weight of 20kg), and productivity cannot be sufficiently improved

[0007] In addition, in the fine cutting process of cutting the JLB base material, such as Figure 4 As shown, the JLB base material is unwound from the take-up drum 3 installed on the JLB cutting machine. After each cutting, it is necessary to manually replace (replace) the new take-up drum, so the replacement takes a long time. thus not being able to adequately increase productivity
