  • Linerless web utilizing apparatus and methods having dual function stripper element
    Patent number: 7186043
    Abstract: There is disclosed a printer with an arrangement for assuring that a linerless tacky adhesive-backed web is reliably fed. The printer has stripper elements which terminate at tip portions which extend into the platen roll to initially cut grooves in the platen roll, and because the tip portions extend below the outer periphery of the platen roll into these grooves, the stripper elements continue to strip the web reliably from the platen roll during subsequent printing cycles.
