Abstract
A knife cylinder for processing weblike material has at least one slot in its cylindrical surface for receiving a web cutting/perforating knife retained in place by a plurality of pressure medium cylinders distributed over the length of the knife. A rigid wall within the slot limits the extent of the pressure cylinders, and push rods extending through the wall may be provided for transferring pressure from the pressure cylinders to the knife.
