A mandrel, adjustably mounted on a base and adapted to cooperate with a conveyor belt to form a strip of dough into torus shape, is provided with a plurality of longitudinal extending fins projecting outwardly from the rear end portion of the mandrel. The fins cut partially through the dough from the inside circumference of the torus. The mandrel may be provided with another fin, slightly wider than the first mentioned fins, to cut through the dough completely along one radius and cause the dough to assume the shape of a long roll as it falls from the rear end of the mandrel.
