Cutting method of dough

The invention discloses a cutting method of dough. A device used in the method comprises a conveyer belt (1), a lengthwise cutting hob unit (2), and a transversely cutting die component (3), wherein the lengthwise cutting hob unit (2) and the transversely cutting die component (3) are arranged on the conveyer belt (1) in order. The working process is characterized in that: the conveyer belt (1) drives moving dough to move at the same speed, the dough passes through the lengthwise cutting hob unit (2), the hob cuts the dough into narrow strips with same width, the narrow strips continues moving with the conveyer belt, when the narrow strips are close to a switch, a signal is sent out, the conveyer belt stops, the transversely cutting die component (3) works to cut the narrow strips into triangle wrappers with same size. According to the invention, the cutting effect is good, and the efficiency is high.
