Abstract
An extrusion die assembly, adapted to be secured to the discharge end of an extruder, for producing extruded products having different sizes and/or shapes from a single extruder without interrupting the operation of the extruder. The die assembly includes a block having an inlet duct to receive thermoplastic material discharged from the extruder, and a pair of discharge ducts which diverge axially from the inlet duct and terminate in a pair of spaced die plates. A cylindrical diversion valve is rotatably mounted in the die assembly at the convergence of the outlet ducts and the inlet duct, with the valve having an angled passage extending therethrough for directing the flow of thermoplastic material from the inlet duct into one of the outlet ducts. The diversion valve enables thermoplastic material to be diverted from one die plate to the other without interrupting the operation of the extruder.
