Title:
PRODUCTION DEVICE AND PRODUCTION METHOD FOR CHOPPED GLASS STRANDS
Document Type and Number:
WIPO Patent Application WO/2014/148288
Kind Code:
A1
Abstract:
Provided is a production device for chopped glass strands wherein deep grooves do not easily form in the surface of a rubber-covered roller even when the peripheral speed of a cutter roller is set faster than the peripheral speed of the rubber-covered roller. A production device (100) for chopped glass strands equipped with a rubber-covered roller (11) for conveying downstream glass strands (F) supplied from upstream and a cutter roller (10) for cutting the glass strands (F) while rotating in contact with the surface (11a) of the rubber-covered roller (11), in which the rubber-covered roller (11) and the cutter roller (10) each rotate in a manner such that the slip ratio (S) of the cutter roller (10) to the rubber-covered roller (11) represented by formula (1) constantly varies by positive values. (1) S(%)=(v1/v2-1)×100 (v1: peripheral speed of outer periphery of cutter roller; v2: peripheral speed of outer periphery of rubber-covered roller.)
