DEVICE FOR CUTTING FOAMED PLASTIC

摘要

A cutting apparatus for plastic foam solids or the like comprises a cutting wire system having a plurality of substantially parallel cutting wires attached eccentrically to at least two parallel supporting rods, the supporting rods being substantially perpendicular to the cutting wires and spaced from each other with clearance so that the plastic foam solid can be passed therebetween, the ends of the supporting rods being held rotatably pivotable in a rod frame, and also comprises an oscillating drive associated with and engaged to the supporting rods so as to rotatably oscillate the supporting rods about their longitudinal axes wherein the rod frame with the upper end of the frame pivotable around an axis parallel to the cutting wires is supported in a suspension recess of a frame support and is held with the aid of an adjustable strut adjacent the lower end of the rod frame against a supporting abutment projecting from the frame support, and that the rotatable lower end of at least one supporting rod is connected by way of a radial socket coupling with the oscillating drive. The rod frame is advantageously removed from the frame support with the aid of a raising apparatus which is preferably a pneumatic piston cylinder apparatus.
