Abstract (en)
[origin: EP2878391A1] The invention relates to the pressure treatment of metals, specifically to producing a metal strip using cold deformation. The strip is consecutively drawn with back and front tension through bending devices. Moreover, the degree of deformation of a strip is regulated in each bending device by means of changing the ratio of the speed of the strip exiting a bending device to the speed of that strip entering that device, in such a way as to avoid a break in the metal, the required number of bending devices being selected on the basis of the total stretch factor of the strip and on its maximum allowable stretch factor. The result is increased deformation of the strip and reduced energy consumption.
