  • Machine for the manufacture of tubes deformed to provide a helicoidal profile for heat exchangers and similar applications
    Patent number: 4624122
    Abstract: For manufacturing tubes of the "corrugated" type, i.e. comprising at least one deformation of helicoidal profile, the smooth tube (28) is displaced axially inside a fixed sheath (7) about which rotates a sleeve (4) fixed to a head forming support for at least one radially mobile "corrugating" knurl; the displacement of the knurl is effected by a cam (25-26) which surrounds said head and which is actuated by a jack (13-14). Opposite this "corrugating" knurl there is provided a cutting knurl which cuts the tube at the end of the "corrugation" operation. The number of the "corrugating" knurls may vary.
