ABSTRACT A dispenser for wound rolls of flexible sheet material, such as, paper towels, toilet tissue or the like has inwardly facing tracks on the opposite inner side walls of the dispenser housing to receive therein outwardly projecting spindles carried by wound rolls to be dispensed for the rolls to move in succession downwardly relative to the tracks with a section of the lower end of each track slanting away from a feed roller mounted adjacent the lower end of the dispenser housing and each track having at such lower end section a pivotally mounted roll rotation driving guide biased toward the track center to form the lower side of each track section slanting away from the feed roller. A pressure roller is biased into rotating engagement with the feed roller for flexible sheet material to drivingly pass therebetween with the pressure roller having at least one resiliently deformable segment that is eccentric to the pressure roller axis to pick up the leading free end of sheet material on a full roll and lead it into the nip between the feed roller and pressure roller, this pressure roller also has axially spaced conical resilient portions along the length thereof with the conical portions facing from the opposite ends of the pressure roll inwardly toward the mid-point of the pressure roll to promote spreading out the sheet material passing between the feed roller and the pressure roller. A serrated cutting knife is pivotally mounted within the feed roller to sever the sheet material, the serrations on the knife being spaced to accommodate therebetween the deformable eccentric segment and the conical portions on the pressure roller during initial projection of the knife from within the feed roller in severing the sheet material. The cutting knife swings about an axis laterally displaced from the plane of a radially outward portion of the knife and cam followers are carried by the ends of the knife extending beyond the ends of the feed roller with the followers displaced from the pivot mounting axis of the knife. Stationary cams are mounted adjacent the ends of the feed roller with which the cam followers on the knife edge engage to positively project the knife cutting edge beyond the feed roller periphery and retract the cutting edge upon rotation of the feed roller.
