A belt conveyor formed by winding an endless molding belt around a driving roller and a driven roller is rotatably supported on a bed by axially supporting the driving roller and the driven roller at symmetrical ends, and the bed is supported on one side. Inside the frame formed only in the opening, the other end is fixed to the frame closing side with one end in the width direction facing the opening, and from the upstream of the upper part of the belt conveyor. An auxiliary roller mechanism in which a pair of left and right auxiliary rollers are arranged side by side with a forming width formed in the middle downstream, a bread dough winding mechanism, and the forming plate is urged toward the forming belt by spring force. And a forming mechanism that is rotatably supported by the frame is sequentially arranged, while a compacting mechanism in which a compacting plate is movably connected to an elevating mechanism is disposed under the belt conveyor. Is characterized by.

E. Action When a block of bread dough made by kneading wheat flour, water and other additives is put between a pair of auxiliary rollers that are rotating inward, the bread dough is stretched through the bread dough forming width formed between the auxiliary rollers to form a strip. The dough is formed.

The band-shaped bread dough thus formed is dropped and supplied to the upstream side on the belt conveyor that is being rotationally driven, and is conveyed to the downstream side by the forming belt.

When the bread dough is conveyed by the belt, the dough is rolled up between the two by the winding mechanism stationary on the forming belt and the movement of the forming belt.
The bread dough is rolled up from one end and formed into a cylindrical shape, and is conveyed downstream by a belt conveyor.

The column-shaped bread dough thus formed is supplied between the forming plate and the forming belt of the forming mechanism as the forming belt advances, and in the process of passing between them, the bread dough is wound and formed and then rolled by the forming belt. It is supplied by being dropped upstream on the pressure plate in the pressure mechanism.

Next, the column-shaped bread dough on the rolling plate rolls on the rolling plate in the downstream direction as the forming belt advances, and is further formed into a column shape in the rolling process.

By performing such winding, winding, and forming operations, the bread dough is formed into a spiral columnar shape having a predetermined diameter, and the bread dough is supplied from the downstream end of the pressure plate to the product receiver.
