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.

An improved pinch-point gap adjustment mechanism for a dough sheeter having a frame supporting a pair of substantially parallel rollers aligned to form a pinch-point, comprising: a pair of retaining plates attached to the frame, each retaining plate further defined by a groove; a release bar slidingly inserted into said grooves; a pair of release lever, each of said release levers attached to opposing ends of said release bar; a pair of lever arms, each of said lever arms pivotally attached to opposing ends of said release bar; a pair of drive blocks, each of said drive blocks pivotally attached to one of said lever and further defined by an internally threaded bore; a pair of adjusting shafts, each of said adjusting shafts having a first end and a second end, terminating in an adjusting handle at said first end, including an externally threaded portion adjacent to said second end, and threadedly engaged with said internally threaded bore of one of said drive blocks; a pair of upper brackets, each of said upper brackets comprising an attaching means for rotatably attaching an upper bracket to one of said adjusting shafts such that rotating said adjusting shaft results in axial movement by said upper bracket relative to said adjusting shaft; a pair of lower brackets, each of said lower brackets pivotally attached to one of said lever arms; a pair of slider plates, each of said slider plates attached to one said upper bracket and one said lower bracket; and a pair of face pieces, each of said face pieces attached to one of said slider plates, and further comprising a roller bearing assembly for supporting one of the rollers, whereby rotation of said adjusting shaft results in a front-to-back movement of one roller such that there is a resulting change the pinch-point gap between the two rollers.
