METHOD FOR MOUNTING CYLINDRICAL BODIES OF SHEET STRUCTURES Russian patent published in 2006 - IPC B21D51/10 

Abstract RU 2269394 C2

FIELD: manufacture of metallic vessels.

SUBSTANCE: method comprises steps of making blank in the form of coiled web with strips fluid-tightly secured to its surface; forming cylindrical body by uncoiling coiled web and joining its mutually abutted lengthwise edges; reinforcing body by means of helical rigidity ribs due to deforming strip and body part under said ribs; fastening bottom and lid. Before reinforcing cylindrical body with use of helical rigidity ribs, detachable soft jigs are arranged on body from above and below and they are fluid-tightly secured to end edges of body. Said jigs are made of water- and air impermeable elastic material.

EFFECT: lowered labor consumption, enhanced efficiency.
