Abstract
Tension spikes in a running web slit to direct output webs to respective upper and lower cutoff knives are minimized by anticipating the increased tension in the web when the lead edge enters an outfeed nip and offsetting the tension spike with a decrease in the force imposed by the infeed pull roll nip, whereby the sum of the web tensions is substantially uniform through the cutting cycle and the sheets are cut to a consistent length.
