The material to be processed is placed between the feed roll and the center roll. Each adjacent roll rotates in progressively higher speeds. For example, if the feed roll (first roll) rotates at 30 rpm, the center roll should spin at 90 rpm and 270 rpm on the last roll. The material is transferred from the center roll to the end roll by adhesion.
