ABSTRACT:
A method for embedding a reinforcing element within a molded thermoplastic body and a device for accomplishing said method which comprises a single extrusion head, having a duct for feeding thermoplastic material to a sizing run. The axis of the duct is at an acute angle to the axis of the sizing run and the said sizing run communicates in its portion opening into said duct with a co-axial chamber through which a reinforcing element is fed to said sizing run. The cross-section of the sizing run is greater than that of the chamber whereby the reinforcing element will be located intermediate the opposed sides of said sizing run.
