Abstract
A dispenser for cutting and feeding a web of flexible sheet material is described in which a feed roller carries a web cutting blade and a spring connected to an eccentric crank affixed to the feed roll. While initial movement of the web through the mechanism and actuation of the cutter to effect partial separation of the web material is produced by the user's pull on the web, such pull also loads the spring which, upon unloading, delivers the cut web material from the dispenser. The spring is designed to gradually arrest rotation of the feed roll and to be exhausted of stored energy at a predetermined position of the feed roll whereupon the uncut segments of web material are efficaciously severed and the leading end of the succeeding web material is automatically positioned where it can be readily grasped by a subsequent user.
