The invention relates to a tape dispenser for producing lengths of tape. The tape dispenser comprises a rotatable roller on which the tape is wound up and a rotatable take-off roller across which the tape to be taken off is guided. The take-off roller has at least one perforation element that is directed against the surface of support of the tape and that is used to perforate the tape. The dispenser is further provided with latch elements that block the take-off roller if the tape has covered a certain distance once it has been perforated. The latch elements release the take-off roller once the perforated section at the tape's end is separated from the tape.
