Abstract

A printing machine for printing on a web includes a plurality of guide rollers for guiding the web through a simplex and a duplex path in the printing machine. The duplex path is adjacent and laterally shifted with respect to the simplex path. An apparatus for turning or laterally shifting the web and transfer the web from the simplex path to the duplex path includes four rollers. 90° twists are present between rollers 1 and 2 and between rollers 3 and 4. Rollers 1 and 4 are substantially parallel, and rollers 2 and 3 are substantially parallel. Rollers 1 and 4 are substantially at right angles to rollers 2 and 3.
