Abstract

1,074,639. Corrugating tubes. ROHRLEITUNGSBAU WERDAU VEB. Oct. 10 1964, No. 40023/64. Heading B3E. Flexible corrugated metal pipes for expansion joints is formed from previously grooved pipe 1 by a radially displaceable inner roller 4, which also rotates the pipe 1, co-operating with two outer rollers 3 which engage in the previously formed grooves and move axially towards one another to apply the corrugation shaping force. The ends of the pipe may be formed by inner and outer rollers (6), (5), Fig. 4 (not shown).
