Abstract

818,635. Making tubes and sheathed cables; angular bending. PIRELLI-GENERAL CABLE WORKS Ltd. Oct. 2, 1956 [Oct. 18, 1955], No. 29725/55. Classes 83 (2) and 83 (4). Apparatus for manufacturing tubing from metal strip in a plurality of forming stages is characterized in that all the forming means individual to a single forming stage are carried upon a single support plate arranged transversely to the axis of progression of the strip, said plates being adjustable in the direction of progression of the strip. Removable plates 1, secured in slotted supports 2 fixed on a base 3 and adjustable longitudinally along a key 4, have mounted therein rollers 6, 7, 8, 9 which form strip fed therethrough into a longitudinally-seamed tube which is then welded by means mounted between plates at 5. The rollers may be freely mounted in the plates, the strip being pulled through or carried on a transversely flexible belt which passes through the forming means with the strip, or the rollers on one or more plates may be driven. The plates are closely spaced so that the strip does not spring open between them. The central rollers 6 of the plates support and bend the strip and have profiles of a radius greater than that of the finished tubing and which decreases in successive stages from plate to plate while the side rollers 7 and 8 form the sides of the strip equal to that of the finished tubing. The rollers 9 guide a cable to be sheathed and press upon the edge of the strip. The rollers may be adjustable in the plates. Rollers 30, Figs. 7 and 9, accommodated in a cruciform slot 15 in a plate 11 are carried by forks 32, adjustable along keys 17 on the plate 11 by screws 29, the bottom roller may not however be adjustable.
