Drive rollers for film precessing batch - has high grip coating on film grip surface and on drive belt rollers

摘要

The drive rollers (3) for the film strip are located on a central spindle (1), with drive belt rollers (2) on either side, also threaded on the spindle. The rollers rotate freely on the spindle and are linked together for a common drive. The roller surfaces are coated with a grip layer to prevent drive belt slip and to grip the film strip through the process fluids. A silicone rubber, or similar coating is applied to the hard plastic rollers to form a secure friction grip with min film damage. The plastics rollers and the coating are not attacked by the process fluids.
