A tape dispenser for applying adhesive tape to a substrate surface, the tape having a first surface with a pressure sensitive adhesive thereon and a second surface. The dispenser includes a housing suitable for holding and dispensing a roll of tape. The housing has an exterior application surface that has a tape dispensing opening therein. A plurality of cylindrical rollers are provided within the housing, each roller having an outer surface. The outer surfaces of the rollers coact with each other and the tape surfaces to retain, guide and feed the tape through the tape dispensing opening to the exterior application surface. The outer surface of at least one of the rollers protrudes through the application surface on one side of the opening enabling frictional contact of the roller surface with the substrate surface. When the application surface of the tape dispenser passes over the substrate surface in one direction the outer surface of the roller engages the substrate surface causing the roller to roll along the substrate surface and to coact and drive the outer surfaces of the other rollers. This causes the rollers to grip the surfaces of the tape and feed the tape through the opening enabling the first surface of the tape with the pressure sensitive adhesive thereon to contact the substrate surface and adhere thereto. Optionally, the outer surface of another of the rollers protrudes through the application surface on the other side of the opening to contact the second surface of the tape as it is fed through the opening. Thus when the application surface of the tape dispenser passes over the substrate surface in the one direction the outer surface of this other roller contacts the second surface of the tape to apply pressure to the tape causing the first surface of the tape with the pressure sensitive adhesive thereon to adhere to the substrate. A cutting blade is mounted to the application surface on the one side of the opening with the cutting edge facing the interior of the housing, whereby when the dispenser is moved in a direction different than the one direction, the tape is cut by the blade. |
