A device (10) for applying tape from a roll thereof to a surface is disclosed. In particular the device has utility for applying drywall tape to flat or corner joints formed by meeting sheets of drywall material. The device has a cast head (14) and a handle (12) attached to one end thereof, the head being adapted to releasably and rotatably mount a roll of tape therein. A roller assembly (70) at the other end of the head includes frame members (72) pivotally mounted to the head, with guide and applicator rollers (82, 86) rotatably mounted between the frame members. For flat joints the rollers are both cylindrical, and are at least as wide as the tape. For corner joints the guide roller (82) is about half as wide as the tape and the applicator roller (86) has an inverted V-shaped profile for pushing the tape into the corner. As the device is moved along the corner tape fed from the roll is initially formed to have a transversely concave shape by the guide roller, contacting only the edges thereof, and is finally formed into a right angle by the applicator roller. The roller assembly pivots relative to the head as the device is moved along the corner to keep the rollers in contact with the wall sections defining the corner. A cutting mechanism (102) is provided for severing the applied tape from the tape roll when sufficient tape has been applied to the corner. |
