  • Patent number: 5695105
    Abstract: A cutting roller having cutting blades and a receiving roller are provided downstream of pulling-out rollers for pulling out a web, and the web passing between them is cut. Accelerating rollers rotated at a transmitting speed higher than that of the pulling-out rollers apply a tension to the web. The cutting blades are formed with narrow cutouts, and the receiving roller is provided with narrow annular grooves. Stretched tension guide members extend through the notches and the narrow annular grooves so as to guide the web. The portions of the web corresponding to the notches and the narrow annular grooves are not cut by the cutting blades and are left as uncut portions. However, these portions are broken easily by the tension applied to the web. Since the widths of the cutouts and the annular grooves are very narrow, the torn marks on the broken portions of the web are not remarkable.
