Abstract: The device is used for rolling an edge of a dough piece. It comprises a first mechanism for making a friction engagement with the edge of the dough piece and a second mechanism for moving the first mechanism inwards relative to the edge of the dough piece so that the edge is forced to roll on itself. For instance, this can be realised by a first plate having a plurality of elongated guiding slots. A plurality of followers are slidably mounted in corresponding slots of the first plate. A dough-engaging finger is connected to each follower. The fingers are located under the first plate and moved relative to the dough piece. The device mechanically rolls the edge or edges of a dough piece to form an elevated peripheral portion that prevents the toppings from falling or flowing out of the dough piece during the preparation or when cooked and served by the customers. It also gives a better appearance to the final products.
