Abstract: Apparatus is disclosed for moulding pieces of dough into long thin cylinders. To avoid an irregular shape of the final product and/or a non-uniform interior dough structure, the pieces of dough are rolled over a working surface while pressure is exerted on each half thereof, distributed over a plurality of adjoining transverse zones, by elements of the working surface. Each of the elements is laterally movable substantially in proportion to the local dough migration. For this purpose the invention provides a compression bed for use in an extender over a movable carrier. The side of the compression bed which faces the carrier is constituted by elements symmetrically arranged relatively to the longitudinal median plane of the compression bed and journalled for lateral movement.
