ABSTRACT:
The present invention involves a portable taping tool for applying tape over joints in wallboard, sheet rock, gypsum board, drywall, and the like. The taping tool has a main frame which has a dispensing chamber for joint compound, a mounting for a roll of tape, main rollers, a second roller, and a tape cutting blade. In one embodiment, the second roller is a corner roller that not only creases the tape but also squares it in the corner. In another embodiment, the second roller is a substantially cylindrical roller which has a slightly concave shape to its working surface. The cylindrical, second roller is used to apply tape over flat joints and its slightly concave shape serves to concentrate the joint compound towards the middle of the tape so that joint compound will be more evenly distributed when the tape is wiped down. The second roller of each of these embodiments can be rigidly supported in a forward, extended position or spring biased in a forward, extended position. The tape cutting blade in each of the embodiments is supported to move along a path between the main rollers and second roller. With the taping tool of the present invention, the tape can be more easily seen and more accurately cut to fit the wallboard section, corner joint, or ceiling joint. Further, once the tape is cut, the end of the freshly cut tape still extends outwardly of the tool beyond the main rollers so that the taping tool can be manipulated to apply the tape to a new section without having to manually restring the tape about the main rollers. Rollers are also provided at the tape inlet and tape outlet of the dispensing chamber so that the tape can more easily and smoothly pass through the dispensing chamber.
