Abstract

A method of operating a flying shear for cutting a rolled strip, which includes at least one drum provided with a blade, includes synchronizing a peripheral speed of the blade with a feed rate of the rolled strip, and cutting the rolled strip by effecting a partial penetration of the blade in the rolled strip to produce a weakened location of the rolled strip, and by tearing the rolled strip at the weakened location by a tensile force.
