Abstract:

A method for continuously forming molded parts includes providing an extruder; directing a hollow column of plastic material from the extruder; providing a plurality of die blocks each including planar end segments having differing geometry and joined by the intermediate convoluted segments; continuously moving such die blocks for receiving and forming the hollow column into strut boots with planar end segments and intermediate convoluted segments and advancing the shaped column of plastic material from the continuously moving die blocks and providing a cutter synchronized to the movement of the shaped column for separating the planar end segments to form one or more parts having planar end segments of the same or differing geometry in each part or with differing geometry from part to part.
