ABSTRACT:
A hand operated dry wall taping tool includes a tubular main body portion, to be held by the operator, with a tape applicator head portion at one end thereof. The tool is supplied with dry wall tape cement from a supply thereof under pressure. A supply roll of dry wall tape is carried from the main body of the applicator, the tape is fed through the applicator head onto the wall joint to be taped. In the applicator head, a pair of tape drive wheel portions engage the tape and press it against the wall for taping a seam between two adjacent sections of dry wall. As the drive wheels pull the tape through the applicator head, dry wall cement is applied by the applicator head to the side of the tape which is to engage the wall. In one embodiment, a spring biased swivel roller presses the cement laden tape into engagement with the wall as the tape is applied to the seam. In an alternative embodiment, a flexible resilient wiper blade carried from the head presses the cement laden tape into engagement with the wall and in addition feathers the cement onto the dry wall along both side edges of the tape with but a single pass.
