Abstract
Abstract 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.

Claim 1
Independent Claim
130 words
An apparatus for shaping bakery products comprising a mandrel having a solid section and a tubular section detachably secured to said solid section, said tubular section having a plurality of longitudinally extending fins projecting outwardly from its circumferential surface to engage torus shaped pieces of dough moved longitudinally of the mandrel whereby said fins cut partially through said torus shaped pieces of dough from the inner circumferential surface of said torus, a conveyor belt substantially embracing said mandrel to impart a rotational axial movement to said pieces of dough as it moves them longitudinally along said mandrel, and said tubular section being so located, relative to said solid section, as to discharge said pieces of dough with the slits positioned on the outer circumferential surface of said pieces of dough.
