Abstract

901,394. Making helically seamed tubing. KUCKENS, A. Dec. 23, 1958 [Oct. 10, 1958], No. 30521/60. Divided out of 901,391. Class 83 (4). A method of producing tubes with a helically disposed welding seam in which strip, guided at its edges, is fed by a roll assembly into a coiling shaper box or die positioned obliquely to the path of the strip is characterized in that the reactions of the forces appearing as a result of stresses or constraints in the strip and/or the positioning of the strip are utilized for adjusting the operation of the feeder roll assembly for compensating inaccuracies in the travel of the strip. Strip 201 from a coil 202 is fed through straightening rolls 231 by driven feed rolls 204, 205, urged together by an hydraulic ram 206, through guides 219, 220 and between lateral guides 221, to rollers 223, 224, 225, the latter two driven by means 228, in a sleeve-like shaper tool 222 where the strip is coiled into a tube 236. The edges of the strip are engaged by guides 234, 235 on which are provided pressure measurement heads so that, if the strip presses too hard against one or other guide, a frame 203 for the feed rolls 204, 205 is caused to pivot slightly about a vertical axis by gear means 229, 208 to relieve the pressure. The same effect can be obtained by moving one feed roll bearing 237, Fig. 4, laterally by hydraulic cylinder means 238, or 239, controlled by the pressure measurement heads or one of the rams 206 at the ends of the feed rolls may be pressed down more heavily than the other. The straightening roll system 231 is movable laterally on rollers 232, 233. Specification 901,392 also is referred to
