The dough-rolling machine comprises two dough rollers, the upper one being adjustable in height. Two dough-conveyor belts are guided over inner conveyor-belt rollers. Between each of these rollers and the lower dough roller is a measuring roller. The dough is rolled out in several passes, one or the other of the conveyor belts serving alternately as the feed belt. The speed of rotation of the dough rollers is constant, as is the speed of the conveyor belt transporting the dough away from the dough rollers. The speed of the conveyor belt feeding the dough is adjustable and is regulated by means of the measuring roller measuring the actual rate of feed of the dough. Optimum control of this feed rate is important in order to avoid undulation or overstretching of the dough, which can destroy it, necessitate rerolling, or result in excessive rejects. The dough-rolling machine needs no operator.
