Abstract

PURPOSE: The titled apparatus, capable of cutting and crimping a continuous filament tow with a pressing force, in which the continuous filament tow is wound around a rotor having cutting blades, cut and passed through a crimping chamber.
CONSTITUTION: A continuous filament tow T is wound around the outer periphery of a drum type rotor having many peripheral cutting blades 16, and pressed by a pressing roller 5 to the central part of the rotor and cut to give a cut filament tow S, which is filled in a crimping chamber and crimped. The crimped tow Sa is then taken out of openings 22 at the inner periphery. The relation between the length L of the tow path at the blade tip part and the length b of the shortest tow path in the crimping chamber is set as follows: 2.2≥L/b≥1.8. According to the method, a crimped staple fiber of uniform crimps can be continuously produced from a continuous filament tow by a through process.
