ABSTRACT:
An improved pinch-point gap adjustment mechanism for a dough sheeter having two counterrotating rollers, one of which is horizontally moveable, is disclosed. The pinch-point gap adjustment mechanism incorporates a lever-action arrangement to provide mechanical assistance to an operator adjusting the pinch-point gap. The lever-action incorporated by the current invention distributes input forces for pinch-point gap adjustment across the height of the moveable roller. The disclosed invention allows for smoother pinch-point gap adjustment such that binding of the slider plates is minimized. The preferred sheeter head assembly permits an operator to release the front roller from the same operator location as where adjustments to the pinch-point gap are made.
