Document Type and Number:
WIPO Patent Application WO/2016/120922
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a method for manufacturing a rubber sheet incorporating a steel cord, the method enabling the steel cord to be easily, stably, and continuously bent and disposed on the rubber sheet, and a manufacturing device suitable for implementing such a manufacturing method.
In the manufacturing method according to the present invention, a steel cord is secured by three chucks disposed at regular intervals, and the central chuck is rotated to a position above a conveyor. The chuck installed at a location which is furthest from a rubber sheet is moved in a parallel manner so as to reduce the distance between the chucks at the ends. The steel cord that has been bent is disposed on a plane and is sandwiched between two rubber sheets while the shape thereof is maintained. The positions of the chucks at the ends are switched each time the steel cord is bent, and the central chuck repeats the rotating motion.
