Abstract
Abstract A self-adhesive product according to the invention comprises two opposing surface layers (1, 2). Therebetween is laid a release layer (4, 5) and an adhesive layer (6). Release layer (4, 5) consists of two components in a manner that a first release layer component (4) is formed as a part of first surface layer (1) and a second release layer component (5) is similarly formed as a part of second surface layer (2). At said first release layer component (4), said adhesive layer (6) extends substantially to second surface layer (2) and vice versa.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
100 words
A self-adhesive product, characterized in that said self-adhesive product comprises two opposing surface layers (1, 2) with a release layer (4, 5) and an adhesive layer (6) laid therebetween, that said release layer (4, 5) consists of two components in a manner that a first release layer component (4) is formed as a part of first surface layer (1) and a second release layer component (5) the same way as a part of second surface layer (2), and that, at said first release layer component (4), said adhesive layer (6) substantially reaches into second surface layer (2) and vice versa.
Claim 2
Dependent Claim
100 words
A self-adhesive product, characterized in that said self-adhesive product comprises two opposing surface layers (1, 2) with a release layer (4, 5) and an adhesive layer (6) laid therebetween, that said release layer (4, 5) consists of two components in a manner that a first release layer component (4) is formed as a part of first surface layer (1) and a second release layer component (5) the same way as a part of second surface layer (2), and that, at said first release layer component (4), said adhesive layer (6) substantially reaches into second surface layer (2) and vice versa.
Claim 3
Dependent Claim
39 words
A self-adhesive product as set forth in claim 1, characterized in that the first (4) and second (5) release layer component are partly aligned with each other in a direction perpendicular to the principal plane of the surface layers.
Claim 4
Dependent Claim
64 words
A self-adhesive product as set forth in claim 1 or 2, characterized in that said adhesive layer (6) is divided into sections by means of spacer webs (10), which are free of adhesive material and so positioned that said adhesive layer (6) is divided into a component (8′) attached to the first surface layer and a component (9ʹ) attached to second surface layer (2).
Claim 5
Dependent Claim
29 words
4 A self-adhesive product as set forth in one of the preceding claims, characterized in that said release layer components (4, 5) are substantially negative patterns of each other.
Claim 6
Dependent Claim
29 words
A self-adhesive product as set forth in one of the preceding claims, characterized in that a release .layer component (4, 5) consists of substantially identically shaped components or zones.
Claim 7
Dependent Claim
31 words
A self-adhesive product as set forth in one of the preceding claims, characterized in that said release layer components (4, 5) are substantially of the same shape in both surface layers.
Claim 8
Dependent Claim
46 words
A self-adhesive product as set forth in one of the preceding claims, characterized in that the release layer comprises adjacent, elongated zones in both surface layers, whereby said adhesive layer (6) is adapted to adhere to surface layer (1, 2) over the areas between said zones.
Claim 9
Dependent Claim
88 words
A self-adhesive product as set forth in one of claims 1 to 6, characterized in that said release layer (4, 5) and adhesive layer (6, 8) have rectangular and square sections or areas, arranged in rows in a manner that said sections or areas in release layer (4, 5) and adhesive layer (6, 8) are alternating in each row and that successive rows, at each section or area of release layer (4, 5), are provided with a section or area of adhesive layer (6, 8) and vice versa.
Claim 10
Dependent Claim
25 words
A self-adhesive product as set forth in one of the preceding claims, characterized in that said self-adhesive product is in the form of a web.
Claim 11
Dependent Claim
58 words
A self-adhesive product as set forth in one of the preceding claims, characterized in that said self-adhesive product is an endless continuous form, at least whose one side is provided with a perforation zone, the pro duct being intended for double-sided printing, applied to the exposed faces of said surface layers and effected by means of a printer.
Claim 12
Dependent Claim
30 words
A self-adhesive product as set forth in one of the preceding claims, characterized in that said surface layers (1, 2) comprise independent products that are completely removable from each other.
Claim 13
Dependent Claim
30 words
A self-adhesive product as set forth in one of the preceding claims, characterized in that said surface layers (1, 2) are joined together at one edge of said self-adhesive product.
Claim 14
Dependent Claim
26 words
A self-adhesive product as set forth in claim 12, characterized in that said joint is a fold (11) which is formed between surface layers (1, 2).
Claim 15
Dependent Claim
32 words
A self-adhesive product as set forth in claim 12, characterized in that said joint is formed by using a separate joining strip (12) which seals the edges of surface layers (1, 2).
