Abstract
A dispenser for dispensing tape, particularly a ribbon of tape, from a roll uses guide and feed rollers to define the path of the ribbon, at least sufficient of these rollers are shaped to apply a significantly higher unit tension to the ribbon along a central longitudinal portion of the ribbon than is applied along the longitudinal side edge portions of the ribbon on opposite sides of the longitudinal central portion so that forces tending to tear the tape adjacent to the side edges of the tape are significantly less than the forces in the center whereby breakage of the tape is minimized.
