A cam on each end of the adjustable roller controls the roller gap. The hand crank drives one of the nip rollers, and a gear linkage drives the other, so both rollers are positively driven. Roller gap is controlled by an adjustment screw on the roller stop. Adjustable dams in the resin bath and on the nip rollers allow for a range of fabric widths and weights. The rollers open to make it easy to load and clean.
Fabrics can follow several different paths on each model to accomodate a range of fabric weights.
