Abstract
A tape dispenser holds a stock roll of tape (3) which has adhesive on one or both sides. A section of tape (4) is played out around an idle roller (7), which at times also translates to form a surplus tape loop (16), and around two or more cutter bars (2) mounted in a drum (1) which is powered to turn by a gearmotor (55). The cutter bars can also rotate individually in their bearings (61), and are powered to do so by a cam action inside the drum. When the drum advances, the differential rotation of the cutter bars creates tension in a section of tape, thus tearing it into a segment (5). The length of the tape segment may be preselected by means of an adjustment disk (100). The object of the invention is to sequentially cut and then present each tape segment to a convenient dispensing position. When a user grasps and lifts the tape segment from the cutter bar, the gearmotor automatically restarts to cut and present a new tape segment.
