Abstract
A lightweight, compact roving cutter for chopping fiberglass roving into short fiber segments, and used in conjunction with a hand-held resin spray gun, has a cutter roller carrying a plurality of blades, a back-up roller cooperating with the cutter roller and the blades thereof for breaking or cutting the roving, and an idler roller cooperating with the back-up roller for feeding roving between the cutter and the back-up roller. The back-up roller is mounted for movement toward and away from both the cutter and the idler rollers in substantially equal increments relative to each, and a positive displacement adjusting means is connected with the back-up roller for controlling the clearance between the back-up roller and both the cutter and the idler rollers, the adjusting means including a manually operable portion remote from said cutter, whereby an operator may conveniently and accurately adjust the clearances between the rollers while the cutter is operating.
