Longitudinal cutting device for foil web

摘要

The longitudinal cutting device produces narrow strips (2) from a foil web (1) by means of a knife beam (3) to which a number of cutting blades (5) are attached alongside each other with spacers (4) between them. The cutting blades have two opposite cutting edges. The cutting blades can be turned on the knife beam in order to change the cutting edge which is in use for the longitudinal cutting of the foil web.
