摘要: An adapter apparatus for splitting a single extrudate into a plurality of extrudates wherein an adapter block of the adapter apparatus has at least three planar surfaces with an inlet opening on one planar surface and outlet openings on the other planar surfaces. A single conduit extends from the interior of the block to the inlet opening while a pair of conduits extend from the respective outlet openings and intersect the single conduit. Goosenecks interconnect each outlet opening to die means. All of the openings on the planar surfaces are circles.

摘要: An extrusion die having a linearly movable mandrel that controls the thickness of the extrudate as it emanates from the die head. A piston within the die head is made part of the mandrel to control the position of the mandrel's edge relative to the die's outlet opening, with sensing means in the die assembly and being operative to provide a signal indicative of the relative position of such mandrel to the die head.
