Abstract: A dough divider having a dough chamber and, reciprocating therein, a dough feeding plunger for feeding a batch of dough to a measuring chamber whose volume is adjustable for producing pieces of dough of any desired volume and weight. For the driving of the dough feeding plunger, this is connected to a driving motor through the intermediary of a spring device. To avoid undesired working of the dough in the dough chamber during feeding of the dough to the measuring chamber, the spring device in the dough divider according to the invention is double-acting, and the dough divider is provided with an adjustable abutment which stops the dough feeding plunger as it moves away from the measuring chamber, such that the effective volume of the dough chamber may be adapted to the measuring chamber volume as set. Since the spring device is double-acting, relative motions between the driving motor and the dough feeding plunger can be absorbed by the spring device in both directions of travel of the plunger.

Abstract: A dough rounding machine with a drum rotatable about a vertical axis, a frame disposed around the drum and a trough which is formed between the drum jacket and a number of trough elements mounted on the frame and extending helically adjacent the jacket. Each trough element has a rail fixedly mounted in the frame and abutting the drum, and a wall portion positioned on the rail and displaceable relative to the jacket. The dough rounding machine further comprises a control unit for adjusting the width of the trough, the unit comprising rotatable rods extending from the lower part to the upper part of the drum and substantially parallel to the drum jacket, and link means interconnecting the rods and the wall portions.
