One type of device comprises means whereby a tape backing is deformed as the tape is bent back upon itself at an angle as it detaches from a roller to which it has been adhered. An alternative type of device comprises means whereby a tape backing is deformed as the tape is deformed into grooves on a fluted roller.

  • Tape applicating and severing assembly
    Patent number: 3992244
    Abstract: An apparatus for applying severed strips of double-coated adhesive tape to a substrate from the face of a carrier liner. A length of tape having adhesive on both sides and disposed on a release liner is fed continuously past a severing means which cuts the tape into strips but does not sever the liner. The tape strips are then carried by the liner to an applicating member where the strips of tape are applied to a moving substrate.
