Abstract
A vehicle is wrapped by an adhesive film which is then slit by applying first tape to the vehicle having a longitudinally extending filament carried by the tape at a position spaced from the side edges. A second tape is applied over the film at the first tape body so as to bridge to each side of the filament and pulling the filament so as to tear through the film and the first ad second tapes body with the second tape applying a force to the film acting to reduce tendency of the film to pull away from the object during the cutting by the filament as the filament is pulled.
Claims8
A tape comprising:
- a tape body having a front surface, a rear surface, a first longitudinal side edge and a second longitudinal side edge;
- the tape body having an adhesive on the rear surface for attachment to an object;
- the tape body having a first and a second longitudinally extending filaments attached thereto, wherein the first and second filaments are arranged such that the second filament when pulled passes through a slot formed by pulling the first filament through the tape body;
- wherein the first and second filaments are attached to the tape body at a position thereon spaced from both side edges of the tape to a distance which allows bending of the tape in a first side to side direction by extension of the tape along the second longitudinal side edge and in a second side to side direction by extension of the tape along the first longitudinal side edge.
