<p>A method and apparatus for granulating previously molded solid thermoplastic material for recycling by introducing the previously molded thermoplastic material into a cylindrical granulating zone in a direction parallel with the axis of the cylinder, providing a stationary knife at a cylindrical boundary of the granulating zone, moving a second knife along the cylindrical boundary of the granulating zone to pass in proximity to the stationary knife and thereby trap portions of the previously molded thermoplastic material therebetween to cut the previously molded thermoplastic material into granules, providing an apertured surface as a portion of the cylindrical boundary and sweeping portions of the previously molded thermoplastic material along the apertured surface with the moving knife to cause cut portions of the previously molded thermoplastic material having granule size less than that of the apertures to pass therethrough for recycling by subsequent molding or other processing.</p> |
