摘要： PCT No. PCT/SU80/00212 Sec. 371 Date Aug. 19, 1982 Sec. 102(e) Date Aug. 19, 1982 PCT Filed Dec. 24, 1980 PCT Pub. No. WO82/02156 PCT Pub. Date Jul. 8, 1982.A device for helical coiling of pressure vessel shells comprises a frame (4) traversable along the axis of a pressure vessel shell (1). The bottom portion of the frame (4) mounts a pressing mechanism 5 vertically traversable along the radius of the pressure vessel shell. A mechanism (6) for tensioning the steel strip being coiled is located before the pressing mechanism (5) as along the direction of run of the steel strip (13) from a coil (9) towards the pressure vessel shell (1). The pressing mechanism (5) has a beam (23) secured on the frame (4) and provided with forks (21) and rollers (20), both facing the pressure vessel shell. Each of the rollers (20) is mounted in its own fork (21) and spaced apart from another roller a distance 10 to 50 times the thickness of the steel strip (13) being coiled, and is situated on the generatrix of the pressure vessel shell (1) across the entire width of the steel strip (13) being coiled. The steel strip tensioning mechanism (6) is made as a group of rolls (16) of which the extreme two rolls (18, 19), as in the direction of run of the steel strip, have a convex and a concave camber, respectively, facing the surface of the steel strip (13). The radius of curvature of said cambered roll surfaces is determined by the thickness and mechanical characteristics of the steel strip (13) being coiled and by the amount of plastic deformation required to compensate for the marginal effect tending the edges of the steel strip (13) to flange outwards when the strip is being coiled onto the pressure vessel shell (1) past the pressing mechanism (5).
