Abstract

The invention discloses a method and device for length measurement of a belt ply. The method comprises the following steps of: when a head of the belt ply reaches a speed-reducing switch, reducing the transfer speed of a conveyer belt; when the head of the belt ply reaches a fixed length switch, recording an instantaneous position a when the head of the belt ply reaches, improving the transfer speed of the conveyer belt after end of the recording, and when a tail of the belt ply reaches the speed-reducing switch, reducing the transfer speed of the conveyer belt again; when the tail of the belt ply reaches the fixed length switch, recording an instantaneous position b when the tail of the belt ply reaches, and improving the transfer speed of the conveyer belt again after end of the recording; and computing the length of the belt ply according to the a and the b. The moment to cause the head of the belt ply to reach the speed-reducing switch is earlier than the moment to cause the head of the belt ply to reach the fixed length switch.

Description

technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to a method and a device for measuring the length of a belt layer. Background technique [0002] Belt layer, also known as supporting layer, hard buffer layer and stabilizing layer, refers to the material layer that tightens the carcass along the circumferential direction of the tread centerline under the tread base of radial tires and belted bias tires. [0003] The raw material of the belt layer is rolled into a roll with a continuous length of about 100 meters. In actual production, the coiled belt layer raw material becomes the belt layer after being unwound, measured and cut (this process is also called fixed length). Then the belt layer is conveyed by the conveyor belt and attached to a cylindrical drum (belt layer bonding drum) to join the head and tail of the belt layer. Because there are magnets on the surface of the belt lamination drum and steel wires inside ...
