Abstract

A device and method for guiding a transversely stable material web. The device contains at least one roller and one counter roller disposed on opposite sides of the material web. The roller and counter roller can be swiveled synchronously with each other, thereby holding the material web between each other with a clamping grip. This device provides a substantially higher guiding force in relation to the running direction of the web than devices with stationary abutments.
