High-speed - cutting device for cutting of reinforcing elements for a pneumatic tire.

摘要

Cutter consists of a tubular guide through which the reinforcing wire slides as it is drawn from a spool, with the downstream end of the guide defining the point at which the wire is cut. The cut lengths of wire adhere to a support. The wire is cut into sections, the wire can be cut while is it pressed against a support by a roller. The cutter (4) consists of a tubular guide (40) through which the reinforcing wire slides at a given speed as it is drawn from a spool, with the downstream end (41) of the guide defining the point at which the wire is cut. The cut lengths of wire are deposited on a support and adhere to it. The wire is cut into sections by a cutting implement (42) which rotates about a shaft driven by a satellite gear (44) meshing with a fixed toothed wheel (46) so that the satellite gear rolls round it and intersects the trajectory of the reinforcing wire at the cutting point. The implement incorporates a cam mechanism so that it the implement is active at the cutting point after a given number (n) of passes, where n is two or more, and the wire can be cut while is it pressed against a support by a roller.
