Abstract
An apparatus for feeding web material from a supply roll to processing equipment of the type that exerts an intermittent pulley force on the web during intermittent advance through the processing equipment. The web feed apparatus includes a brake for controlling unwinding rotation of the web supply roll which is operated under the control of a dancer to decrease the braking action when the web is fed at a rate faster than the rate at which it unwinds from the supply roll. The web feed apparatus also includes web feed rollers arranged to drive both sides of a folded web while both sides of the web are under the same tension.
