ABSTRACT:
An extrusion apparatus having an internal deckle system, includes a deckle blade that extends through an end of the apparatus into a flow passageway. The apparatus may beneficially include a cold-formable, sealing member for preventing leakage through the apparatus end. In a variation, the apparatus may include an upstream deckle plug that includes a sealing member formable under heat and compression to prevent leakage transversely past the upper deckle plug. In a further variation, a full width, upper deckle plug may extend through an end of the main body into the manifold. A wavy or scalloped edge may be avoided by an extended portion that extends downwardly and terminates at or near the exit orifice.
