Abstract

An intermittent web transport apparatus in a printing machine guides the web between two processing positions and through an intermediate festoon. Web alignment deviations from a nominal value are corrected by rotation of a pivotable frame that is positioned downstream of the festoon. A correction roller before the festoon effects a shifting of the web prior to its entry into the festoon.
