Abstract

1,255,740. Winding and reeling; curving. DEMAG A.G. 14 March, 1969 [7 June, 1968], No. 13658/69. Addition to 1,224,223. Heading B3E. Apparatus for continuously bending tubes as described in the parent Specification is characterized by the last pair of rollers 2b, 3a adjacent the tube outlet being mounted on a common housing 5, a lever 6 attached to the common housing, a guide-bar 6 secured to the casing 4 to guide a roller 6a along a defined path and so position the last pair of rollers to obtain the desired radius of curvature of the tubes.
