FIELD: metallurgy.
SUBSTANCE: cutting is carried out in two stages. In the first stage, preliminary incisions are made on the moving strip. In the second stage, by deforming the shear at the notches, the workpiece is separated from the strip. Two interlocking two-roll stands are used, the first of which carries out preliminary notches on the strip, and in the second one - a shift in the places of the notch.
EFFECT: expanded technological capabilities.
