ABSTRACT:
To obtain flat component strips from a cold-rolled metal strip inexpensively and with the minimum use of technical apparatus, slitting shears 5 are disposed between sets of tensioning drums 3, 4; 11, 12, more particularly between the inlet side set of tensioning drums 3, 4 and a straightening unit 6 of a stretch flattening apparatus for a metal strip 1. This arrangement of the slitting shears eliminates the additional stretch flattening of the component strips otherwise required after the metal strip itself has already been stretch flattened. The component strips between the two sets of tensioning drums 3, 4; 11, 12 also acquire the same length.
