Abstract

332,870. Meyer-Keller et Cie, Akt.- Ges., O. Jan. 18, 1929, [Convention date]. Tubes.-A tube 1 is corrugated by a profiled ring 4 mounted in a ball bearing 5 in a rotating head 3 and displaced slowly eccentrically to the tube axis by means of a bell-crank 7 engaging a lug 6 on the outer race of the bearing; or the tube may be rotated and the ring given a transverse movement only. The tube is fed forward through the bush 2 by rubber rollers. The portions between the corrugations are formed into crests by subsequent upsetting. Eccentric grooves may be formed by mounting the tube eccentrically in the head whereby pipe bends 1 as shown in Fig. 4 may be produced.
