ABSTRACT:
An improved apparatus for chopping glass strands is disclosed. The improvement comprises a feed roll for attenuating the strand prior to chopping with a surface having a series of deep grooves cut at desired angles with respect to the sidewalls of the roll. These special grooves reduce binder collection on the surface of the feed roll thereby reducing the tendency of glass strand to wrap around the feed roll during attenuation.
