ABSTRACT:
A duplex extruder head for receiving extrudate from each of two extruders to deliver a composite unitary extrudate such as tire tread stock has a cavity plug or vee-block insert secured in an open top channel-shaped receiver without bolts or hinges by a pair of slidable clamps. The head also has a transverse slot for slidably receiving a die assembly endwise into the slot. The die assembly is then elevated to operating position and securely clamped by a pair of wedge-like gibs. Clamping of either the insert or the die assembly is effected by hydraulic cylinder or equivalent means. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
