ABSTRACT:
A tape applicator effectively applies adhesive-backed drywall tape along both flat joints and corner joints. The applicator has a common tape dispenser to which a flat joint header and a corner joint header can be removably attached. The dispenser includes a tape guide located near a tape outlet for the dispenser as well as a tape break. The flat joint header has a cylindrical application roller with a resilient surface that allows the roller to follow the contour of the wall while maintaining proper pressure distribution to completely and securely press the tape against the wall. The corner header includes a creaser wheel that creases the tape into a corner and a guide roller that guides the tape from the dispenser outlet to the creaser wheel. A corner roller having a resilient surface can be used effectively to wipe down creased tape over a corner joint. Both the flat joint and corner headers include tape cutters to selectively cut tape dispensing from the apparatus. The applicator can be used with many kinds of adhesive-backed tapes, including reinforced drywall tape, fire tape and mesh tape.
