TAPE APPLICATOR
First Claim
1. In a dispenser for pressure-sensitive adhesive tape comprising in combination an applying and buffing member having a buffing surface, a blade movable to and out of a severing position relative to said buffing surface, guide means for positioning the blade adjacent the buffing surface, a guard member movable relative to said buffing surface to an operative position adjacent to said buffing surface to expose said buffing surface to an adjacent tape receiving surface from a normal position spaced from said buffing surface when said buffing surface is spaced from a said receiving surface, and means connecting said blade to said guard member to move said knife in said guide means from said severing position when said guard member is moved to said operative position adjacent said buffing surface and to said severing position when said guard member is returned to said normal position.

Abstract
A tape applicator for holding and applying adhesive tape and for applying random lengths of tape to a receiving surface and for severing the roll of tape from the tape applied. The dispenser has a pressure actuated guard which is moved against a spring into the dispenser upon engaging the guard with the surface to receive the tape with sufficient force to move the guard. This movement of the guard retracts the knife and positions a tape applying roller to apply the free end of the tape supply to the receiving surface. After the predetermined length of tape has been applied pressure on the dispenser is relieved and the guard and knife return to their normal positions with the knife moving across the path of the tape between the applying member and the applied tape to sever the same as the dispenser was withdrawn.

2. In a dispenser according to claim 1 comprising spring means for biasing said guard member to said normal position.
-
3. In a dispenser according to claim 1 wherein said buffing member is movable on an axis and said guide means is defined by a slot in said buffing member eXtending along a chord intersecting said buffing member surface adjacent said buffing surface, and said guard member is pivoted on an axis parallel to the axis of said buffing member and on the side of said axis of said buffing member opposite said slot.
-
4. In a dispenser according to claim 2 wherein said guard member is movable to said operative position when engaged by a receiving surface applying a force thereto opposite the bias of said spring means, and wherein said buffing member is movably mounted on an axis for movement about said axis upon said guard member being moved to said operative position to place said buffing surface in position adjacent a tape receiving surface.
