Abstract: An extruding device includes an extruder cylinder, a screw, and a rotary drive for the screw. To facilitate installation and removal of the assemblies of the extruding device, the screw end facing the rotary drive does not protrude during operation into bearings provided between the extruder cylinder and rotary drive, particularly not into a thrust bearing.

Abstract: A method for aligning a cutter spindle of a granulator, particularly an underwater granulator, relative to a cutting plate includes rotationally driving the cutter spindle with a drive motor, measuring a force acting on the cutter spindle, generating a corresponding signal, and adjusting especially the angular alignment of the cutter spindle relative to the cutting plate as a function of the signal by pivoting the cutter spindle about at least two pivot axes which enclose an angle with each other A granulator, particularly an underwater granulator, for producing plastic granulate, has a cutting box and a cutter spindle, a cutter holder rotatably received in the cutting box, and a drive motor connected to the cutter spindle, and is configured to perform the aforedescribed method.

Abstract: The present invention relates to a method for aligning a cutter spindle of a granulator, particularly an underwater granulator, relative to a cutting plate (4). As precise an alignment of the cutter spindle is of great significance here for continuous very high to optimal quality of the granulate. According to the invention, such can be achieved by the following steps. Rotationally driving the cutter spindle (14) by means of a drive motor, measuring a force acting on the cutter spindle (14), generating a corresponding signal, and adjusting the alignment and especially the angular alignment of the cutter spindle (14) relative to the cutting plate (4) as a function of the signal.

Abstract: In a process and apparatus for producing TPE foam profiles, material is heated up in a conveying zone at a temperature of 180.degree.-210.degree. C. and a pressure of 100-200 bar. The melt then passes through a two-stage shear process consisting of two spaced shearing sections separated by a homogenizing section in which the melt and water are intimately mixed, with the melt being exposed to a further homogenizing section in which the melt is intensively mixed and homogenized prior to being extruded through a profile die.
