Abstract

A roller knife cutter includes a first knife shaft pair for severing a ferromagnetic metal sheet into sheet metal strips forwarded in a first direction of advance; and a plurality of substantially coplanar plates arranged downstream of the first knife shaft pair in a series in the first direction of advance. The plates are separated from one another by a clearance. The cutter further has an endless belt having an upper run moving in a second direction of advance and positioned in the clearance and extending parallel therewith. The upper run has a lowered position in which a top surface of the upper run is at a level below the top surfaces of the plates and a lifted position in which the top surface of the upper run is substantially coplanar with the top surfaces of the plates; and a plurality of individually height-adjustable magnet units arranged in a series underneath the upper run parallel to the second direction of advance. Each magnet unit has a low position allowing the upper run of the endless belt to be situated in the lowered position and a high position raising the upper run into the lifted position.
