A cross-head die which is comprised of a die body with a flow chamber, a plurality of die cavities, die elements within the die cavities, communication between the die cavities and the flow chamber, a means for individual flow adjustment to each die cavity, and a means for axial motion of the filamentary member(s) through the die elements. The single flow chamber communicates to a plurality of die cavities through individual radial flow ports. The flow chamber is open at one end and closed at the other except for a cleaning hole. Within each of the radial flow ports resides a device for adjusting flow restriction. Within each die cavity is a cylindrical die piston. A gap created between the die piston and the die cavity defines a path for resin flow. The resin flow path is tapered to a point at which the filamentary member exits from a smaller cylindrical bore through the center of the die piston. The resin is deposited on the filamentary member as it moves through the die piston to produce a composite matrix strand.

[ What is claimed is:] [12.]12. A cross-head die for coating a plurality of filamentary members with thermoplastic resin comprising.an elongate main body;a flow chamber located within the main body having one end in communication with the exterior of the main body and the other end closed, wherein the closed end of the flow chamber is sloped towards an adjacent flow port and has a sealable opening whereby the adjacent flow chamber may be cleaned;a plurality of die cavities formed in said main body, each in communication with one flow port opposite the flow chamber; anda plurality of die elements disposed within the die cavities, whereby an exterior of a die element and an interior of a corresponding one of the die cavities defines a resin flow path.
