Abstract
The web-fed printing machine has two cylinders (2, 3) which form the nip, a paper-web-directing device (10) with an infeed roller (14) and a discharge roller (15), which are arranged adjustably on both sides of the nip (S), and an upstream web-feeding device (20), which likewise exhibits an infeed roller (22) and a discharge roller (23). In order to align the paper web, the web-directing device (10) can be displaced in a plane running through the axes of the rollers, and can be adjusted as a function of the signals from web-edge sensors (16, 17) such that it can be adjusted in the direction of the axes of rotation of the rollers and can be pivoted into an oblique position. The web-feeding device (20) can be pivoted about a stationary spindle (24) and is connected mechanically to the web-directing device.
