Abstract
392,460. Cleaning metals. MAYWEG, H., 82, Freibergerstrasse, Holzwickede, Westphalia, Germany. Nov. 21, 1932, No. 32848. Convention date, Nov. 30, 1931. [Class 82 (ii).] Apparatus for the continuous manufacture of welded tubes comprises means for scaling, pickling, and shaping to tube form strip material and means for welding, finishing, and cutting the tubes into lengths, arranged as a unitary plant through which the strip is moved at a speed dependent upon that required for welding it. A strip of metal 1 supplied from a reel and led through an equalizing device, which permits the joining up of fresh strips without stopping of the machine, is scaled by passing it around fixed and movable grooved rollers 13, 14, Figs. 5 and 6 (not shown), which are relatively adjustable to accommodate different gauges of material. The pickling apparatus comprises top and bottom guiding rollers 25, 27, Fig. 7, supported in a removable frame 23, the rollers 25 being driven from a motor 29 and the rollers 27 positioned to guide the strip through an acid mixture in a tank 22. The pickling action is assisted by scrubbing devices 28 in the form of prassava brushes, wood wool or the like. The acid is removed by passing the strip through a second scrubbing device 46 and a rinsing tank 45 positioned below sprinklers 48.
