Abstract: A rolled food dough having a good shape is stably produced. The rolled food dough is arranged on a conveyor in an orderly manner. A roll-forming device and method having high production capacity are provided. The downstream end portion PL of the food dough piece P is deflected by a middle-speed conveyor 1 and a high-speed conveyor 3 facing each other in an up-down direction, folded and adhesively pressed between a following low-speed conveyor 2 and the high-speed conveyor 3 to form a rolling core PA, and rolled due to a speed difference between the facing conveyors.

Abstract: A device for roiling up flat dough around or without a filling to produce a rolled food product is comprised of: a first belt having an end and moving in a first direction toward the end to convey the dough with or without the filling laid on the first belt; a second belt so disposed adjacent to the end as to make the dough conveyed in the first direction be brought into contact with the second belt to curve the dough and movable in a second direction perpendicular to the first direction; and holding members arranged along the first belt to guide the dough curved along the second belt around along the holding members, whereby rolling up the dough.

Abstract: The inventions relate to an apparatus for aligning and positioning pieces of food dough with predetermined orientations and at predetermined intervals, and provide an aligning and positioning apparatus that can easily adjust positions of the pieces of food dough in a perpendicular direction to a moving direction of the pieces and that can process at high speed. An aligning and positioning apparatus of the inventions includes a holding unit having a plurality of holding mechanisms to hold a plurality of pieces of food dough carried by a first conveyor, a driving mechanism of the holding mechanisms, guide members to control the positions of the holding mechanisms in the perpendicular direction when the holding mechanisms are moved by the driving mechanism, and a positioning mechanism to adjust positions of the guide members in the perpendicular direction.
