Abstract: In the production of various kinds of pastry it is actual to effect a folding-over of wing portions of flat dough members, such that these portions are folded down over some stuffing deposited e.g. on a middle area of the dough member. While this is easily done manually, it has been very difficult to automatize the operation, but according to the invention this is achieved in a very simple and efficient manner. A rubber resilient shaping plate (8) is used, which, through foldable areas (12), is connected with projecting wing portions (10) each associated with a depending rubber rod (16). At their lower ends these rods are rigidly attached to an actuator plate (18), which, in being raised relative to the shaping plate (8), urges the rubber rods upwardly for folding the wing portions (19) up- and inwardly.
