Abstract
Abstract This invention pertains to a system of counterfoil binding, fit in particular to classify documents in the form of loose sheets; it includes a number of thin superposed strips (2), which are bound together by any convenient means and covered, on either side, with an adhesive layer (1), characterized by the fact that the whole of the adhesive surface (1) is covered with a coating (3) in which is provided at least a line (4) of least resistance making it possible to partially remove the film (3a) as to substitute for it at least part of the loose sheet to be classified (7); in this way the sheet lies in the prolongation of the detached part (3b) of the film.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
165 words
A counterfoil binding for classifying documents in loose-leaf form, comprising: a plurality of thin superimposed strips bound together at a lateral edge in pad-like form and covered on at least one entire side with an adhesive layer; a removable film covering the entire adhesive layer, said film having at least one line of least resistance for facilitating partial removal of the film from the surface of said strip, said film having a thickness which is at least as great as the thickness of the documents to be classified and said at least one line of least resistance being parallel to the bound edge of said strip; and wherein each strip and associated film is configured so that removal of a portion of the film along said line of least resistance permits substitution of a loose-leaf sheet for the removed portion of film thereby forming a prolongation of the non-removed portion of the film and the non-removed portion maintains appropriate spacing between said plurality of strips.
Claim 2
Dependent Claim
165 words
A counterfoil binding for classifying documents in loose-leaf form, comprising: a plurality of thin superimposed strips bound together at a lateral edge in pad-like form and covered on at least one entire side with an adhesive layer; a removable film covering the entire adhesive layer, said film having at least one line of least resistance for facilitating partial removal of the film from the surface of said strip, said film having a thickness which is at least as great as the thickness of the documents to be classified and said at least one line of least resistance being parallel to the bound edge of said strip; and wherein each strip and associated film is configured so that removal of a portion of the film along said line of least resistance permits substitution of a loose-leaf sheet for the removed portion of film thereby forming a prolongation of the non-removed portion of the film and the non-removed portion maintains appropriate spacing between said plurality of strips.
Claim 3
Dependent Claim
28 words
The counterfoil binding of claim 1, wherein the film contains at least one additional line of least resistance arranged perpendicularly to the first said line of least resistance.
Claim 4
Dependent Claim
30 words
The counterfoil binding of claim 1, further including at least one additional line of least resistance in at least one film which permits removal of several portions of the film.
Claim 5
Dependent Claim
24 words
A counterfoil binding for classifying documents in loose-leaf form according to claim 1 wherein consecutive attached counterfoil strips are separated by a separating sheet.
Claim 6
Dependent Claim
33 words
The counterfoil binding of claim 1, wherein at least a portion of said thin strips are covered on each side with an adhesive layer with a removable film covering each said adhesive layer.
