ABSTRACT:
In a booklet maker or sheet folder wherein one or more sheets are pushed through a nip formed by a pair of crease rolls, and wherein the crease rolls are driven by gears, a slip clutch is operatively disposed between one of the crease rolls and the gear driving the crease roll. The slip clutch compensates for the abrupt change in frictional coefficient experienced by the crease rolls when one or more sheets enter the nip.
