摘要

A movable tucker apparatus and method include a tucker element having a tip and base at opposite ends thereof, a tucker spring and a tucker positioning lug configured for operative mounting within the slot in a folding roll. The lug is operatively affixed to the roll within the slot and extends at least partly across a width of the slot. The tucker element includes a relief for operative receipt therein of the lug. The tucker element, lug and spring are operatively connected to allow the tucker element to move in and out within the slot, and the tip of the tucker to move circumferentially with respect to the slot when the tucker element is operatively mounted in the slot and the tucker positioning lug operatively disposed within the relief in the tucker element.
