  • Patent number: 4243181
    Abstract: Granulation of materials, particularly materials in stranded form, employing a rotatable cutter with multiple feed channels at different elevational positions along the periphery of the cutter. The granules of the feed material formed by the cutter are collected without further, unwanted cutting by using a separate, pressurizable discharge channel for each feed channel or by providing voids in the cutter through which the granules can fall, desirably with the assistance of feed channel applied pressure.
