Abstract

A transfer/injection molding apparatus and process is defined that includes a charge forming unit. The charge is formed so that the fibers therein are randomly oriented in substantially parallel horizontal planes such that they are always substantially parallel to the direction of initial flow into the cavity of the molding unit. The charge forming unit includes a cutter for cutting sheet material into strips and a wind-up fork for rolling the strips into wrapped charges. The wrapped charges are formed by winding the strips around prongs extending from the wind-up fork. Further, the fork is attached to a robotic arm which loads the wrapped charge into the molding die.
