Zusammenfassung:	PURPOSE: To provide an unvulcanized rubber material cutting method short in cycle time compared with a conventional cutting method so as to be able to improve the efficiency of cutting work and preventing the heating, lateral dislocation and the like of the cut part of cut material so as to be able to perform cutting of high accuracy. CONSTITUTION: At the time of cutting cut material W, the upper and lower faces around the cut part of the cut material W are held while applying tension to the cut part, and the cut part is cut while imparting specified vibration to a rotationally-drivable round blade 13, so that the lateral dislocation of the cut material W can be effectively prevented, and heating during cutting is also prevented. The cut material W can thereby be cut efficiently, and further, cycle time can be shortened so as to be able to remarkably improve the efficiency of cutting work.
