  • Method and device for the cutting of pipes into separate pipe sections
    Patent number: 5074018
    Abstract: A method and apparatus for cutting pipes into sections are described. A punching unit (7) forms apertures (8) in strip (2) from which pipe (4) is formed on winding core (3). A cutting device (5) has a circular shears (10) which has a first, smaller-diameter cutting roller (13) and a second cutting roller (14) each having two cutting edges. The first cutting roller (13) is swivelled through aperture (8) into the pipe (4).
