A dispenser (10, 200) for cutting and feeding a web (W) of flexible sheet material is described in which a feed roller (30, 212) carries a web cutting blade (40, 226) and a spring (104, 290) con- nected to an eccentric crank (102, 288) affixed to the feed roller (30, 212). While initial movement of the web (W) through the mechan- ism and actuation of the cutter (40, 226) to effect partial separation of the web material (W) is produced by the user's pull on the web (W), such pull also loads the spring (104, 290) which, upon unload- ing, delivers the cut web material from the dispenser (10, 200). The spring (104, 290), following arresting rotation of the feed roll (30, 212) and exhaust of stored energy, operates, upon continued pull- ing of the web (W), to impart gradually increasing stress on the un- cut web segments until they break, whereupon the uncut segments of web material (W) are efficaciously severed and the leading end (WE) of the succeeding web material is automatically positioned where it can be readily grasped by a subsequent user.
