ABSTRACT:
An apparatus for continuously extruding pliant material into thin sheets. Rather than following the standard approach of using cooperating rollers to extrude the material, in the apparatus of the present invention, the material is extruded through the cooperative interaction of a multi-sided rotor mechanism and a reciprocating barrier member. This arrangement overcomes many of the drawbacks inherent in extrusion devices of standard design including the undesirable tendancy of the material being extruded to tenaciously adhere to the rollers after extrusion.
