Abstract
The invention relates to a method for winding metal strip (B) helically onto tubes (R), the tube (R) being rotated and the strip (B) being adapted to the respective curvature of the tube with cold deformation, the strip (B) being drawn edgewise and under tensile stress onto the tube (R), with increasing deformation from the bottom to the top edge, and, immediately before being applied to the tube (R), is subjected to a rolling process which promotes the adaptation of the strip (B), running in in a straight line, to the respective curvature of the tube. In order to be able to carry out high-speed winding, even of strips which are susceptible to tearing, preferably those made of aluminium, onto tubes, particularly those whose cross-section deviates from the circular, a centripetal compressive force is applied by means of a pressure roller (16) to the top region (K) of the strip (B) running onto the tube (R). <IMAGE>
