Abstract

1,260,549. Making helically secured tubes; seaming. BOWATER FLEXPIPE Ltd. 23 June, 1970 [27 June, 1969], No. 32614/69. Headings B3A, B3E and B3J. [Also in Division F2] A method of producing helically grooved flexible tubing comprises helically winding a longitudinally corrugated metal strip S, having flanges 10 and 12 projecting in opposite directions, on to a rotating mandrel 2 so that the flanges overlap one another, folding over the overlapping flanges to form a continuous seamed joint, and bending over a corrugation 70 adjacent the seamed joint so that it engages over and locks the seamed joint in position. The strip, corrugated by rolls 14, is fed against the face 8 of a guide ring 6 so that the flange 10 is held between a joint blade 68 and the face 8. The strip is then fed by the rotating mandrel 2 under a former block 15 which comprises former plates 16 and 17, Fig. 4, a plurality of guide plates 18 with spacer plates 19 interposed between them, and a single guide plate 20 having corrugations 21. The forming plates 16 and 17, coact with one another so that the corrugation 13 is bent towards the flange 10 while the flange 12 is bent towards the flange 10, Fig. 10, after which the overlapping flanges are bent over so that they lie parallel to the axis of the mandrel, Fig. 12. The joint is then partially flattened by a driven, knurled roller 31 and is finally flattened by a driven pressure roller 33. Clinch rollers 57 and 57a finally bend the corrugations 70 over the flattened seam.
