Abstract
Abstract An improved adhesive sheet and method of manufacturing it, the sheet comprising a number of adhesive parts and support parts on its rear surface, said adhesive parts and support parts being alternately arranged equidistantly over the whole area of the rear surface. A single adhesive sheet may be folded so that two sheet halves are brought in contact with one another at their rear surface, wherein the adhesive parts of one sheet half are located opposite to the support parts of the other half, while the support parts of the one sheet half are located opposite to the adhesive parts of the other sheet half. Also, two blank sheets, may be used and made to overlap in substantially the same manner. The adhesive sheets require no protective sheet. The sheets are made by coating the rear surface of one sheet half or blank sheet with an adhesive agent, allowing the rear surfaces of both sheet halves or two blank sheets to overlap and then compressing the overlapped sheet halves or blank sheets with the aid of suitable compressing means, thereby effecting transference of the adhesive agent from the support part of the adhesive-coated sheet or sheet-half to the uncoated adhesive basis of the other sheet or sheet-half.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
202 words
A display poster comprising a pressure-sensitive adhesive sheet capable of removably adhering to a substrate without damaging said substrate, said composite sheet comprising: (a) a single base sheet having first and second surfaces; (b) a plurality of distinct strips of pressure-sensitive adhesive material affixed on said first sheet surface and bearing a pressure-sensitive adhesive for adhesively but removably affixing said sheet onto said substrates, said adhesive strips lying substantially on the same plane, said plane being elevated with respect to said sheet surface; (c) a plurality of distinct non-adhesive strips also affixed on said first sheet surface, said non-adhesive strips also lying on substantially the same plane, said plane also being elevated with respect to said first sheet surface and substantially of the same elevation as the plane of said adhesive strips, said non-adhesive strips supporting said base sheet so as to lie even on said substrate; said adhesive and non-adhesive strips being alternately disposed in an equally spaced relation on said first sheet surface, thereby leaving a substantial portion of said first sheet surface free; and (d) indicia consisting of the display of said poster disposed on said second sheet surface; wherein said substrate is different from said second sheet surface.
Claim 2
Dependent Claim
202 words

Claim 3
Dependent Claim
25 words
A composite adhesive sheet as described in claim 1 wherein said adhesive and non-adhesive strips are raised off the plane of said first sheet surface.
Claim 4
Dependent Claim
20 words
A composite adhesive sheet as described in claim 2 wherein said adhesive and non-adhesive strips have substantially the same configuration.
Claim 5
Dependent Claim
21 words
A composite adhesive sheet as described in claim 3 wherein said adhesive and non-adhesive strips are arranged in columns and rows.
Claim 6
Dependent Claim
17 words
A composite adhesive sheet as described in claim 4 wherein said non-adhesive strips are made of plastic.
Claim 7
Dependent Claim
33 words
A composite adhesive sheet as described in claim 4 wherein said adhesive and non-adhesive strips are arranged to extend substantially across the full surface area of said first surface of said base sheet.
Claim 8
Dependent Claim
50 words
A composite adhesive sheet as described in claim 4 wherein said sheet further comprises a fold line at a predetermined position whereby said sheet can be folded and a predetermined number of said non-adhesive zones and said adhesive zones can thereby be disposed opposite each other in a predetermined arrangement.
Claim 9
Dependent Claim
23 words
A composite adhesive sheet as described in claim 7 wherein said opposed adhesive zones and non-adhesive are brought into contact with each other.
Claim 10
Dependent Claim
81 words
A composite adhesive sheet assembly comprising a first composite sheet according to claim 4 disposed opposite a second composite sheet according to claim 4 whereby said first surface of said first sheet is opposed to said first surface of said second sheet and said adhesive zones of said first sheet abut said non-adhesive zones of said second sheet and said non-adhesive zones of said first sheet abut said adhesive zones of said second sheet, said sheets removably adhering to each other.
