Abstract
A rollout apparatus for rolling trapped air from a resin impregnated fiber mat has two carriage assemblies mounted for reciprocated movement in opposite direction. Each of the carriage assemblies carries depending rollers that engage an impregnated fiberglass mat laid on a mold. The carriage assemblies oscillate simultaneously in opposite directions so that the turning forces generated by the receiprocation cancel each other, thus providing a smooth vibration-free mechanism.
