HIGH-SPEED SHEAR FOR TRANSVERSELY CUTTING ROLLED STRIP

摘要

A high-speed shear for transversely cutting rolled strip with knife carriers which can be driven for rotation and are arranged in pairs opposite each other. The knife carriers are arranged with a fixed distance between each other on both sides of the strip in a common shear cassette. The shear cassette is mounted within an outer frame and the shear cassette is provided with a lifting device for raising or lowering the shear cassette within the outer frame. In a method for operating the shear, the two knife carriers are moved into a horizontal position for allowing the strip end to enter or travel through, and the shear cassette is moved within the outer frame into a raised transfer position.
