Abstract
The inertial drag of idler rollers in a web-offset press with independently driven drive rollers is compensated by successively advancing downstream rollers during speed changes. This prevents low-tension conditions on the web and subsequent web breaks. Compensation is made for inertial coupling to the idler rollers through the web. Tension control is utilized to stabilize web position during startups and splices.
