ABSTRACT:
A granulator for comminuting plastic web scrap has features that allow it to also granulate three dimensional objects. The granulator has a pair of nip rollers mounted above a cutter assembly for drawing the web into the cutter assembly. The nip rollers have grabbing devices for grabbing three dimensional objects when they fall onto the rollers, for shredding the objects and forcing them between the rollers. In one embodiment, the grabbing device consists of a groove formed in the surface of at least one of the rollers. The groove has a sharp-edged trailing surface that grabs the article. In another embodiment, the grabbing device consists of a protruding finger that grabs the article. To provide clearance, a circumferential slot is located in the other roller for receiving the finger.
