To provide a compactor that operates without being worn and that is composed of normalized parts available in the mechanical component market at reasonable prices.
The compactor for the preparation of thermoplastic materials placed between two approximately disc-shaped work surfaces at least one of which is rotatably connected to a rotary driven drive shaft, to the rotatable work surface, and to a sleeve that surrounds the drive shaft and that can be operated axially with the drive shaft, whereby the sleeve is fitted with an external thread. The compactor is characterized in that the sleeve 6 cannot rotate and that the sleeve 6 is surrounded on the exterior by a rotatably mounted component 7 which by means of an internal thread meshes with the external thread on the sleeve 6 whereby the outside component 7 may be operated in both directions by means of a driving mechanism.
