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.
Claims5
A method of operating a flying shear for transversely cutting a rolling strip wherein the shear includes at least one drum provided with a blade, the method comprising the steps of:
- synchronizing a peripheral speed of the blade with a feed rate of the rolling strip, cutting the rolling strip by effecting a partial penetration of the blade in the rolling strip to produce a weakened location simultaneously across an entire width of the rolling strip, and tearing the rolling strip at the weakened location by a tensile force, and wherein a mass of the rolling strip that is accelerated by pushing from the blade drum and a tension force created by deflection of the rolling strip act as an anvil for the blade.
