The invention concerns the spreading of dough string when it moves on a cloth band. The spreading is effected by means of a pressing roll having a spiral like ridge around its periphery. The spiral runs from one end of the roll to the opposite end, but alters its spiral direction at the middle area of the roll. According to the invention the spiral roll is kept out of direct contact with the surface of the dough string by a cloth conveyed between the roll and the dough string with the advance speed of the dough. With this arrangement the rotation speed of the pressing roll can be selected independently of the advance speed of the dough string.
