Method for automatic regulation of individual web tensions, involves determining force exerted on folding funnel by track or partial track guided on each folding funnel

摘要

The method involves determining the force exerted on the folding funnel (02) by the track (07) or partial track guided on each folding funnel. A real web tension is derived on the basis of the determined force. The actual and desired web tension of the folding funnel are compared to regulate the number of revolutions of a roller (04) in such a way that the actual web tension within the area of funnel corresponds to the desired web tension. An independent claim is also included for a device for automatic regulation of individual web tensions in the area of folding funnel printed by a rotary press.
