Abstract: A comb for binding documents constituted by sheets perforated along one edge, comprising a strip of material in sheet form which has, along one edge, a plurality of comb-like tabs which can be inserted in corresponding holes formed along the edge of sheets that constitute a document to be bound and are longer than the document is thick. The strip has a width which allows folding on the spine of the document and overlapping on the portion of the tabs protruding from the holes. There is also provided an adhesive layer which affects at least the region where the strip and the portion of the tabs that protrudes from the holes mutually overlap.
