ABSTRACT:
The horizontal platform between the feed roll nip and the rotary cutter pelletizing nip in a dicer is arranged to feed soft, limp webs of plastic without crumpling, buckling or sidewise movement by providing a multiplicity of closely spaced ribs and grooves on both the platform and on the hold down fingers, extending in the direction of feed. Friction is thus reduced in the feed direction while sidewise control is maximum for a given feed resistance. To prevent the soft plastic from wrapping around the lower feed roll it is formed with a multiplicity of small diamond protuberances separated by channels.
