Abstract
Abstract Adhesive binding folder for binding loose sheets with two outside enclosing covers, joined to each other by a back strip which carries a double self adhesive layer against which the narrow rear edges of the bound inner sheets are positioned. The layer includes a removable strip to expose the adhesive and thereby adhere to the sheets. An inner protective sheet for the purpose of attachment penetrates with a narrow margin into the contact interface of the self adhesive layer. Said sheet serves to cover the self-adhesive layer laid bare by pulling out individual sheets.

Claim 1
Independent Claim
306 words
An adhesive binding folder comprising: a backing strip; a first coating of self-adhesive material having a first surface, said coating having a substantially uniform thickness and being attached to said backing strip on one surface thereof; two outside enclosing covers which are directly attached to a second surface of said first adhesive coating opposite said backing strip so as to be attached to said one surface of said backing strip by said first adhesive coating, said covers being attached to opposite elongated margins of said backing strip leaving adhesive exposed in the central area of the strip between edges of the covers; and a second coating of self-adhesive material of a substantially uniform thickness covering only a portion of said first adhesive coating and having one entire surface attached to said first adhesive coating, said second adhesive coating being disposed exclusively in the area between the two outside covers whereby individual leaves can be attached to said second adhesive coating between said covers and the total thickness of adhesive being greater in the area covered by said second coating than in the area covered only by said first coating; a carrier strip having a silicone coating on one surface thereof and being attached to said second adhesive coating along the surface having said silicone coating on the side opposite said backing strip and capable of being easily removed from said second coating, whereby the individual leaves can then be attached to said second coating; and an inner protective sheet having an edge zone extending along one of said elongated margins, said zone being interposed between said first adhesive coating and said second adhesive coating, said inner protective sheet being arranged so as to cover at least a portion of the outer surface of said second adhesive coating for covering adhesive exposed by removal of individual leaves.
