Process and apparatus for manufacturing chopped thermoplastic fibers

In a process for manufacturing chopped thermoplastic fibers made directly beneath bushings, especially chopped glass fibers, the thermoplastic fibers are chopped in a region in which an anvil wheel and a blade-holder wheel, rotating simultaneously, are in contact with each other. At least part of th...

Beschreibung
Zusammenfassung:	In a process for manufacturing chopped thermoplastic fibers made directly beneath bushings, especially chopped glass fibers, the thermoplastic fibers are chopped in a region in which an anvil wheel and a blade-holder wheel, rotating simultaneously, are in contact with each other. At least part of the peripheral surface of the rotating anvil wheel in contact with the blade-holder wheel is machined so as to compensate for its wear, while maintaining the anvil wheel in contact with the blade-holder wheel.
