ROTATING JOINT FOR EXTRUSION DIE

摘要

ROTATING JOINT FOR EXTRUSION DIE A rotating joint assembly for feeding an extrusion die with two or more thermoplastic layers of a consistent uniformity of distribution including a stationary manifold for receiving two or more thermoplastic streams and conveying the streams to discharge openings in the manifold, and a cylindrical conduit rotatably connected to the manifold, the conduit having intake openings aligned with discharge openings in the stationary base for receiving and conveying thermoplastic streams from the base to an extrusion die and an axial channel aligned with an axial channel in the stationary manifold for receiving and conveying one of the thermoplastic streams to the die.
