Abstract
A single continuous dough sheet is conveyed by a conveyor up an incline to a dough tension and drive system. In the system, the dough sheet passes around a lower drive roller, around an intermediate drive roller, and around an upper drive roller. The dough sheet extends at a downward angle to an idler roller which directs the dough sheet generally vertically downward in a flat condition. A wishbone pushing element having a rounded V-shape forms the first face of the dough sheet into a generally V-shape having two wings. The wings of the V-shape are then guided by an aligning element such as laterally spaced rollers which roll on the opposite face of the wings to form a folded, two-ply continuous dough sheet. The angular relationship of the legs of the pushing element, the lateral spacing of the rollers of the aligning element and the three dimensional positioning of the pushing element and the aligning element can be adjusted to insure that the free edges in the folded continuous dough sheet are aligned relative to each other.
