  • Method for removing used elastomeric covers from rollers and a device for performing same
    Patent number: 6101694
    Abstract: The method for removing used elastomeric covers from rollers is performed by approaching a rotating cutter head having a number of cutting tools mounted on an indexable insert holder from one end of the cover of the rotating roller to close to the roller core, and moving said cutter head along the rotating roller to the other end of the cover, the circumferential velocities of the cutting tools being from 15 to 70 m/s, preferably from 40 to 50 m/s. For elastomers of up to about 90 Shore A, annular cutting tools are used.
