Abstract
Apparatus for twisting dough comprises juxtaposed conveyor surfaces, each comprising a plurality of laterally spaced-apart conveyor belts moveable in parallel adjacency, each belt of each conveyor surface being juxtaposed with a belt of the other conveyor surface, thus forming a plurality of laterally spaced-apart belt pairs. The juxtaposed conveyor surfaces thus form a conveying passageway. A belt in a belt pair moves at a higher speed than the other belt in that pair, and the speed of the two belts is such that a substantially cylindrical object disposed across adjacent belt pairs is rolled between the adjacent belt pairs as it is being conveyed along the passageway. The speed of the individual belts of the adjacent belt pairs is such that the net velocity along the passageway imparted to the object is the same at each of the belt pairs, but is also such that a greater rotational speed is imparted at one belt pair relative to that at the adjacent belt pair. Therefore, as the object is moved through the passageway, it is twisted without being canted.
