Abstract
A self-contained dry wall taper has a hollow elongated body for holding mastic and supports a roll of tape with tape feeding means to deliver the tape to tape applying wheels that in turn apply it to cover a joint between two wall board sections.A piston is slidably mounted in the hollow body and is automatically moved by a mechanism actuated by the rotating wheels, as they are moved over the wall board surface, to force a layer of mastic onto the tape just prior to it being applied to the surface. Novel tape feeding and tape cutting means are actuated by a single sleeve which is moved forwardly on the hollow body to initially feed the tape into engagement with the tape applying wheels and is moved rearwardly to actuate the tape-cutting mechanism for cutting the tape. A tape creasing disc can be swung into operative position by the operator when the tape is to be applied to an inner corner of a room and it is desired to provide a median crease along the length of the tape and for forcing this crease into the room corner as the mastic and tape are applied.
