Abstract: An elongated sheet of printed material for a roll stamp dispenser having formed flaps serving as driving sprockets and also having perforated score lines for tearing the stamp from the dispenser. A plurality of partially cut spaced apart flap groups formed of flaps along transverse lines mate with driving pins on the roll stamp dispenser. The flaps remain in tact with the stamp roll so as not to destroy the printed appearance of the stamp roll. Perforated transverse continuous score lines are formed at predetermined positions along the longitudinal length of the roll for use in separating adjacent sections of the roll as desired.
