Said tape dispenser comprises a rotatable roller (1) on which the tape (2) is wound up and a rotatable take-off roller (5) across which the tape (2) to be taken off is guided. The take-off roller (5) has at least one perforation element (6) that is directed against the surface of support of the tape (2) and that is used to perforate the tape (2). The dispenser is further provided with means (7, 9) that block the take-off roller (5) if the tape (2) has covered a certain distance once it has been perforated. Said means release the take-off roller (5) once the perforated section at the tape's end is removed from the tape (2).</p> |
