Paper loop stabilisation device for endless paper web in high-speed printer

摘要

The stabilisation device uses an additional device between the feed rollers (ZR) at the beginning of the endless paper web storage loop and the deflection rollers (ULR) at the end of the latter, for providing a loop curvature which cooperates with the force of gravity to ensure a given supply length of the endless paper web (EPB). Pref. the additional device is provided by a fan (G) directing an air jet (LS) onto the rear side of the endless paper web, or by a roller supported at the end of a lever arm.
