ABSTRACT:
A chopper assembly of the type normally mounted on a spray gun to chop and spray fiberglass or the like, and which includes a backup roll driven by an air motor and a cutter roll. The exhaust of the air motor is expelled through air jets in the cutter roll to help drive the cutter roll while also muffling the sound of the exhausting air. The chopper frame is mounted on the gun by a hollow universal joint of the ball and socket type, which carries air to the chopper at any chopper orientation without the need for external flexible hoses or the like.
