Abstract

A variable piston arrangement is provided which is especially adapted for use in roll and bread dividing and shaping machines and includes one or more separate pistons each selectively and operably arranged in a single piston-housing used to size and shape baking dough to predetermined specifications. The piston-housing itself is disposed in a separate housing and as such may function as a separate piston in the following manner. Each of the separate pistons and piston-housing are arranged and controlled so that at least partial removal or withdrawal of one or more of the separate pistons from the piston-housing or withdrawal of the piston-housing from the separate housing will produce a predetermined vacated area or space which conforms to the size and shape of the rolls or bread to be baked. The predetermined area vacated by the one or more separate pistons or piston-housing may be varied in size and shape, as desired, so that a single variable piston arrangement may take the place of multiple piston-housing arrangements required in operating conventional roll and bread dividing and shaping machines used in dividing and shaping rolls and breads of different sizes and shapes.
