Abstract
A die assembly for configuring extrudate flow is provided. The die assembly includes a die head having a feed member passage, first and second die head passages, and first and second die surfaces respectively associated with the first and second die head passages. The die head passages are located intermediate the corresponding die surfaces and the feed member passage. A feed member is supported in the feed member passage of the die head and has a feed passage and a feed opening for supplying extrudate to the die head. The feed member is supported for relative movement within the die head whereby the feed opening may be moved to communicate with either the first die head passage or the second die head passage. The central axis feed of the feed opening is moveable with respect to the central axis of the first or second die head passage to correspondingly configure extrudate exiting the respective die head passage when the feed opening is in communication with this die head passage. The die assembly may also include a switch member whereby the die assembly may be supplied with extrudate material from either a first or second extruder.
