Process for production of molding compositions containing high weight percentage of glass comprising feeding an extruded mixture of glass fibers and molten thermoplastic resin to a crosshead die, coating continuous glass roving with said mixture in said crosshead die, solidifying said molten thermoplastic while said thermoplastic is coated on said roving, and pelletizing the same into pellets containing between about 61 to 90 weight percent glass. The molding composition is in the form of such pellets which generally comprise right cylinders having a diameter of between three thirty-seconds and one-fourth inch and a height of between one-eighth to one-half inch. |
