Abstract

Masking film stacks, kits composed of said film stacks, adhesive tapes, and covering tapes, and methods for producing said stacks and kits are provided. The masking film stacks comprise masking films having widths and lengths, wherein the masking films are foldable along folding lines, running along the lengths, to form double-ply-folded masking films such that two free longitudinal edges of the double-ply-folded masking films run adjacent to each another and the double-ply masking films are foldable to form stacks and the two longitudinal edges lie on the masking film stacks.

First claim

The invention claimed is:

1. A masking film stack comprising:
a masking film having a masking film edge, a manual engagement edge located opposite with respect to the masking film edge, a width, and a length, wherein the masking film is folded along at least one folding line, running along the length, to form a double-ply-folded masking film such that two free longitudinal edges of the double-ply-folded masking film run adjacent to each another and the double-ply masking film is folded to form the masking film stack and the two longitudinal edges lie on the masking film stack, wherein an angle or a curve is disposed between the masking film stack and the manual engagement edge such that the manual engagement edge extends outwardly from the masking film stack, lies externally with respect to the masking film stack, and is freely graspable.

2. The masking film stack according to claim 1 ,
wherein the double-ply-folded masking film is folded in a concertina fold and an outer double ply is placed at least in U-shape around a concertina stack.

3. The masking film stack according to claim 2 ,
wherein the manual engagement edge is turned over backward.

4. The masking film stack according to 1 ,
wherein the double-ply-folded masking film is folded in a helical fold.

5. The masking film stack according to claim 1 ,
wherein the manual engagement edge has colored or tactile marking.

6. The masking film stack according to claim 1 ,
wherein the masking film is a PE, PP, PA, PET or PBT film or is a composite film of PA and PE or PP and PE or is made of paper or is an aluminum foil.

7. The masking film stack according to claim 1 ,
wherein the masking film stack is wound on a cardboard or plastic core.

8. A kit comprising:
an adhesive tape having a carrier and a layer of adhesive for adherence to a working face; and
a masking film having an inner longitudinal edge, an outer longitudinal edge, a width, and a length,
wherein
the masking film is folded along a folding line, running along the length, to form a double-ply-folded masking film such that two free longitudinal edges of the double-ply-folded masking film run adjacent to each another and the double-ply masking film is folded to form the masking film stack and the two longitudinal edges lie on the masking film stack,
the masking film stack and the adhesive tape are configured such that the inner longitudinal edge of the masking film of the masking film stack is connected to the adhesive tape, and
the outer longitudinal edge of the masking film lies externally on the masking film stack on a side of the masking film stack that is adjacent to the carrier of the adhesive tape, is freely graspable, and forms a manual engagement edge.

9. The kit according to claim 8 ,
wherein the adhesive tape has a carrier layer which is a crepe layer or a PVC-containing carrier layer.

10. A masking tape with
an adhesive tape having a carrier, at least one adhesive side for adherence to a working face, and an edge portion; and
a masking film edge of a masking film disposed on the edge portion of the adhesive tape, wherein the masking film has a width and a free manual engagement edge opposite the masking film edge along the width of the masking film, where the masking film is folded toward the edge portion and forms the masking film stack according to claim 1 ,
wherein the free manual engagement edge is disposed lying freely on a side of the masking film stack that is adjacent to the carrier of the adhesive tape.

11. The masking tape according to claim 10 ,
wherein the manual engagement edge lies on a side of the film stack opposite the adhesive side of the adhesive tape.

12. The masking tape according to claim 10 ,
wherein the manual engagement edge has an inner side which is disposed under contact on the film stack and has an outer side which has no contact.

13. The masking tape according to claim 10 ,
wherein the manual engagement edge is turned over in the adhesive tape-remote direction.

14. The masking tape according to claim 10 ,
wherein the adhesive tape takes the form of a crepe adhesive tape or PVC-containing adhesive tape.

15. A method for producing a folded masking tape, by
disposing a masking film edge of a masking film on an edge portion of an adhesive tape,
folding the masking film toward the edge portion and forming a masking film stack,
wherein
a free manual engagement edge opposite the masking film edge along a width of the masking film is disposed lying freely on the masking film stack, and
an angle or a curve disposed between the free manual engagement edge and the masking film stack such that the free manual engagement edge extends outwardly from the masking film stack.

16. The method according to claim 15 ,
wherein the masking film is made into a double ply and folded concertinawise.

17. The method according to claim 15 ,
wherein the masking film is made into a double ply and folded spiralwise.

18. The method according to claim 15 ,
wherein the free manual engagement edge is disposed adjacent to the adhesive tape.
