Abstract

A roving cutting steering mechanism for use with a plural component spray gun for producing fiberglass reinforced products. A roving cutter is mounted on a plural component spray gun with a support plate and a bracket which is easily vertically adjustable by loosening a bolt mounting the bracket on the gun body. Horizontal adjustment is provided by a cam fitting a slot in the end of a bracket which shifts a mounting plate horizontally. The roving cutter being mounted on the plate is steered to align the path of cuttings ejected from the roving cutter to the optimum position for intersecting the fluid path of material being sprayed by the spray gun. Quick easy adjustment both vertically and horizontally of a roving cutter allows optimizing the mixture of roving cuttings with a spray of plural components being applied to a surface.
