Systems and Rotating Rollers

The importance of guard systems for nip rollers has already been emphasized. The sets of nip rollers must close exactly parallel and can be initially checked by trapping a thin piece of paper (e.g. a paper used for rolling cigarettes) to ensure that it is firmly held in the closed nips across the entire width. Rollers not closing properly will permit slippage.
