Abstract
An assembly and method for processing extrudate material containing curves or angles into a predetermined overall configuration, including having a die assembly for an extruder which assembly controls the cross-sectional shape or profile of the extrudate and selectively varies the path of the extrudate as it leaves the die assembly. A support member is provided which has a predetermined overall configuration and profile to receive the extrudate and maintain its configuration. A driving apparatus is also provided for continuously driving either the support member or the die assembly relative to the other while the extrudate is being received in the support member, and until the entire predetermined overall configuration has been completed. The path of the extrudate is variably directed by the die assembly as it leaves the extruder in coordination with the relative speeds involved to conform the extrudate configuration to the predetermined overall configuration of the support member.
