Trommelschere zum Schneiden von schnell laufendem Band, insbesondere Warmband

摘要

The drum shearer has an axially guided push and pull rod (3) to extend and retract the knife (2) in the knife drum (1). The rod is supported by wedge surfaces (5,7) on corresponding wedge surfaces on the knife or knife carrier. The push and pull rod rotates with the knife drum. It is joined to a stationary linear drive (11) via a pressure bearing (12) transmitting axial forces.
