Dough line for processing sticky dough types

A dough line, comprising:

• at least one conveyor for transporting elongated dough pieces on a conveyor surface of the at least one conveyor in a direction of conveyance;
• curl-up means, arranged above the conveyor, for curling up a dough piece conveyed underneath the curl-up means into a cylindrical shape;
• a moulding unit for moulding the curled up dough piece thereby compressing the dough piece in a direction that is axial to the direction of conveyance, wherein the curl-up means comprise a first and a second contact surface extending in the direction of conveyance, wherein:
• the first contact surface is configured for exerting a force onto a leading edge of the dough piece with at least a component in a direction opposite to the direction of conveyance and subsequently curling up the dough piece over a part of its length, and
• the second contact surface is configured for engaging the dough piece at an outer lateral surface of the part already curled up by the first contact surface substantially tangentially with respect to the direction of conveyance and;
• flipping means for flipping over a curled up dough piece to an upright position prior to moulding, wherein the flipping means comprise at least one conveyor surface slanted in a direction perpendicular to the direction of conveyance and inclined with respect to the conveyor surface of the at least one conveyor, the slanted conveyor surface of the flipping means having a maximum inclination with respect to the conveyor surface of the at least one conveyor large enough for flipping over the dough piece.
