  • Publication number: 20120325068
    Abstract: To restrain shifting of a circular blade, and reduce a cutting-in angle of the circular blade with respect to the tape roll main body, both ends of a rotatable blade shaft 38 is supported by a pair of shaft bearings 39a and 39b of shaft supporting members 37 of a tool post 20. The circular blade 21 is mounted to the blade shaft 38, between the shaft bearings 39a and 39b. This prevents the blade shaft 38 from being shifted or bent, restrains shifting of the circular blade 21, and reduce the cutting-in angle of the circular blade 21 with respect to the tape roll main body.
