Abstract
A granulating device for plastic compounds in which cutting knives of a cutting device face the die plate of a granulating head to form granules of plastic strings extruded from the die plate. The cutting knives are supported on a cutting shaft driven in rotation by a drive shaft of a drive motor. The cutting shaft is rotatably supported in fixed axial position in a housing. In order to obtain a planar parallel and central positioning of the cutting knives relative to the die plate, for example, due to thermal displacement, the housing and drive unit are guided together in a displaceable manner on guide shafts having first ends fixed to the granulating head and opposite ends which are vertically supported for universal pivotable movement in the manner of propped cantilever beams.
