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.

First claim

The invention claimed is:

1. 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.

2. The tape according to claim 1 wherein the first and second filaments are side by side.

3. The tape according to claim 1 wherein the first and second filaments are arranged such that the first filament when pulled tears through the tape body to form the slot which divides the tape body into two separate longitudinally extending, side by side pieces.

4. The tape according to claim 1 wherein the tape body has an adhesive on at least part of the width of the front surface thereof on a side of the first filament adjacent the second filament.

5. The tape according to claim 1 wherein the filament and the tape body are arranged such that, with the rear surface attached to the object, the first filament when pulled is pulled from the tape body along the length of the tape body at its position thereon rather than pulling out from one side edge of the tape body.

6. The tape according to claim 1 wherein the adhesive has the characteristic that the tape body can be pulled from a surface of the object without leaving an adhesive residue and without damaging the surface.

7. The tape according to claim 1 wherein the filaments are less extendible than the tape body.

8. The tape according to claim 1 wherein the first and second filaments are carried in or on the adhesive on the rear surface.
