SISTEMA PARA FABRICAR FIOS CORTADOS FEITOS DE MATERIAL TERMOPLÁSTICO.

摘要

A chopping machine chops strands of thermoplastic material coming from a single die into sections having a predetermined length. The machine has a substantially cylindrical chopping wheel provided on its periphery with a number of uniformly distributed blades oriented about an axis of rotation. An anvil wheel wrapped in a plastic material is located adjacent the chopping wheel. The anvil wheel has a device for routing strands between the wheels, thereby drawing out and chopping the strands into sections. The device has two or more pins that project laterally from a face of the anvil wheel. The pins may be movable with respect to the face. A restart process using the chopping machine is also provided.
