ABSTRACT:
A process of forming a tape of long reinforcement in a continuous thermoplastic matrix. A roving of long fibers carrying a thermoplastic resin is introduced into the inlet of a wedgeshaped passage between the tongue and the groove of a tongue-in-groove die. The fibers are bounded by sidewalls for the entire length of the die. Both heat and pressure is applied to consolidate the resin in the fibers while the pressure is adjusted on the rovings by adjusting the inlet and the outlet clearances while the roving is being pulled through the die.
