Zusammenfassung: | PCT No. PCT/SU81/00002 Sec. 371 Date Sep. 9, 1982 Sec. 102(e) Date Sep. 9, 1982 PCT Filed Jan. 15, 1981 PCT Pub. No. WO82/02350 PCT Pub. Date Jul. 22, 1982.A mill for manufacturing bodies of multilayer high-pressure vessels comprises rotators (3) of the body (1) of the high-pressure vessel, which have the butt end portions of the body (1) of the high-pressure vessel secured therein. The body (1) of the high-pressure vessel is surrounded by a portal (5) capable of moving along the body (1) of the vessel. An upper platform (8) of the portal (5) carries a technological line (15) for preparation of the steel strip for its winding onto a central pipe (16) of the body (1) of the vessel, the steel strip (2) being supplied from a coil (18). A crossbar (9) secured to uprights (10) of the portal (5) carries an arrangement (32) for tensioning the steel strip, which can move along the crossbar (9) and from which the steel strip (2) is supplied to the upper generatrix of the body (1) of the vessel in such a manner that a free loop ( 30) of the steel strip (2) allowing for a turn of the arrangement (32) for tensioning the steel strip in the horizontal plane is formed between the technological line (15) for preparation of the steel strip for its winding onto the central pipe (16) of the body (1) of the vessel and the arrangement (32) for tensioning the steel strip. The mill also comprises a fixture for welding the steel strip (2) to the end portions of the body (1) of the vessel and turns of the steel strip (2) to one another. |
