ABSTRACT:
Continuously operable apparatus for the preparation and/or processing of synthetic plastics or rubber moulding compounds, comprising a housing in the form of a channel and a mixing and kneading member engaged in the channel and having a surface which co-operates with the bottom wall of the channel, in which said bottom wall and said surface of the mixing and kneading member are undulatingly profiled in a manner such that the profiles extend transversely or obliquely with respect to the longitudinal axis of said channel and said member, and drive means, including at least one crank drive, coupled between the housing and said member to cause said member and said housing, while retaining their respective orientations to move relatively to one another to cause the peaks of the undulations on one of said surface and said bottom wall to perform a circular movement in associated valleys in the other of said surface and said bottom wall.
Two synchronously movable crank drives may be provided with adjustment means for adjusting the spacing between the mixing and kneading member and the housing.
