A tape applicator (10) applies adhesive-backed drywall tape (36) along both flat joints and corner joints. The applicator (10) has a common tape dispenser (2) to which a flat joint header (3) and a corner joint header (4) can be removably attached. The dispenser (2) includes a tape guide (60) located near a tape outlet (34) for the dispenser as well as a tape brake (69). The flat joint header (3) has a cylindrical application roller (38) with a resilient surface. The corner header includes a creaser wheel (214) that creases the tape into a corner and a guide roller (212) that guides the tape from the dispenser outlet (34) to the creaser wheel (214). A corner roller (5) having a resilient surface can be used effectively to wipe down creased tape over a corner joint. Both the flat joint (3) and corner headers (4) include tape cutters (76 and 260) to selectively cut tape (36) dispensing from the apparatus. The applicator (10) can be used with many kinds of adhesive-backed tapes (36), including reinforced drywall tape, fire tape and mesh tape. |
