Abstract: A receiving device for at least one extrusion worm, disposed in a housing of an extruder, has receiving shafts for the extrusion worms. The receiving shafts are surrounded by slide ring seals, which in turn are disposed in a sealing housing. The receiving shafts are disposed, together with the slide ring seals and the sealing housing, axially displaceably relative to the housing on a frame. The receiving device of the invention prevents damage or harm to the slide ring seals upon removal of the extrusion worms from the housing or installation into it.

Abstract: An apparatus for cutting individual pieces from an extruded strand fed at a constant velocity (v0) has two cutting blades, which are disposed on disks and rotate in circular paths. In order to align the cutting blades perpendicular to the feed direction of the extruded strand, the blade supports holding the cutting blades are coupled to each other by means of guide rods. The guide rods simultaneously constitute the rotation axes of deflection rolls of a conveyor belt transporting the extruded strand.

Abstract: An unwinding machine (10) with forming cylinders (11, 12, 13) has bearing blocks (26, 27) in which the forming cylinders (11, 12, 13) are supported. The bearing blocks (26, 27) are disposed in recesses (32) of partition walls (25, 25a) of the unwinding machine (10) and are secured by means of clamping devices (35). Furthermore, the forming cylinders (11, 12, 13) are coupled to a common drive motor (15). The unwinding machine (10) according to the invention permits a simple exchanging of the forming cylinders (11, 12, 13).
