Abstract
An assembly to crease a paper set in a booklet maker is provided. A booklet is formed in a booklet marker when a crease blade strikes the middle of the stack and pushes it toward a set of nipped crease rolls. The assembly engages spring-loaded idlers against the crease rolls after the crease blade initiates the buckle of the stack and prior to creasing. The spring loaded idlers apply a drive force to the stack that assists the formation of the crease. With the assistance of this extra drive force, the crease blade tip can be stopped in time to avoid jamming while reducing the chance of getting a cover, or more sheets tearing off the booklet. This design is compact in size and therefore may also be retrofitted into existing designs.
