  • 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). Rotary movement of the pipe (4) effects cutting, during which the cutting rollers (13, 14) move in synchronism with the pipe (4) so that the pipe is cut from the inside and the outside by the cutting rollers (13, 14).

  • Patent number: 4538334
    Abstract: A jointing machine for the folding of seams in manufacturing of seamed metal sheets made of segments of metal sheets is disclosed, wherein the machine includes a locking wheel pivotably positioned in a recess of a resiliently disposed locking wheel carriage. The seam during formation is supported from below by a support roller, and is held from the sides by an adjustment roller together with the locking wheel. The locking wheel carriage is positioned diagonally relative to the surface of the support roller, which enables the machine to manufacture folded seams in very small metal sheet segments, and to utilize thick or hard metal sheets.
