Abstract

1,007,608. Making corrugated tubes and cable sheaths. HACKETHAL-DRAHT-UND KABEL-WERKE A.G. May 10, 1962 [May 16, 1961; Feb. 1, 1962], No. 18030/62. Headings B3A and B3E. In an apparatus for producing corrugated weld seamed thin metal tubes, for example cable sheaths, wherein the tubes are formed from strip by rollers, the abutting edges are welded and the welded tubes are moved by a draw-off means interposed between a corrugating device for the welded tubes and the welding head to prevent the corrugating torque being transmitted to the welding point, the draw-off means comprises gripping jaws having guide rollers therein for engaging stationary guide rails, one roller being eccentrically adjustable and the other displaceable on rocker arms. Two jaws 1a, 1b are brought together to grip the welded tube by the engagement of guide rollers 3a, 3b with stationary guide rails and the jaws are carried on endless chains. The jaws carry liners 14a, 14b replaceable for different tube diameters. The roller 3a is adjustable on an eccentrically arranged shaft 5 in jaw 1a and the roller 3b is carried on a shaft 6 mounted between two arms 8, 9 pivoted at one end at 7 to the jaw 1b and resiliently connected at the other end through a member 11 connected to a spring plate 13 whose tension is adjustable by a screw 12. Adjustment of the roller 3a permits clamping force adjustment. The end of the shaft 5 may carry a disc 18 graduated in clamping pressures. The carrier for the jaws may be divided into an upper part and a lower part secured to the endless chains, the two parts being dovetailed together on a slideway. A compression spring is provided between the parts and an elbow lever is pivoted to a projection on the lower part and to a projection on the upper part, the end of the lever carrying a roller. As the jaws close on to the tube the roller rides up on a rail to lock the parts together and when the roller rides off an adjustable part of the rail the upper part is displaced against the spring, the arrangement being such that the jaws exert no draw-off force as they open.
