ABSTRACT:
A dough-stretching roller apparatus is provided to produce a continuous web of dough in a process to manufacture confectionery and bread. The apparatus includes a pair of upper rollers, a sensor means that detects the width of dough at the gap between the upper rollers, and a controller that controls a motor driving the upper rollers in response to a signal from the sensor means. The controller decreases the rotational speed of the upper rollers when the sensors detect that the width of dough is broader than a predetermined width of dough passing through the upper rollers, while the controller increases the rotational speed of the upper rollers when the sensors detect that the width of dough is narrower than the predetermined width of the dough passing through the upper rollers. Thus, even if the amount of dough supplied from a hopper is unstable, production of a stretched web of dough having a constant volume per unit length can be stably continued.
