Patent ID: 8328707

Claim:
A method of folding collations, comprising: rotating a plurality of fold rollers; rotating a plurality of nip rollers, each nip roller forming a nip having a nip spacing with an adjacent fold roller; receiving collations in an input nip; delivering the collations to one of a buckle chute and a deflector to form folded collations in a plurality of intermediate nips; discharging the folded collations from an output nip; and selectively moving each nip roller with respect to the adjacent fold roller based on predetermined collation thickness data to change the nip spacing for sequential collations using an adjustment system associated with the nip roller, wherein the adjustment system includes an adjustment device operative to impart substantially identical motion to the ends of each nip roller shaft, the adjustment device including a fitting rotatably receiving the end of the shaft, and a drive element for moving the fitting with respect to the adjacent fold roller.
