Abstract:
A fastener sheet assembly, comprising:a) a flat backing panel on which file paper sheets are mounted; b) a plurality of superposed thin, flexible, file fastener sheets securely mounted in a flap-like manner along their top longitudinal edge to the top edge of the central section of the backing panel; c) a contact adhesive on the underside of each of the fastener sheets engaging and holding an upper portion of a paper sheet to be mounted on the backing panel; d) the contact adhesive being spaced sufficiently from and below the top edge of each of the fastener sheets, to define a hinge section above the contact adhesive, and, also below it an adjacent outer free relatively wide and graspable disengaging section, which is pulled to disengage the contact adhesive of the fastener sheet from the paper sheet; e) the width of the fastener hinge sections of the fastener sheets being sufficient to permit the fastening sheets to bend back so that paper sheets readily fold back over the backing panel; and f) the contact adhesive is a medium tack reusable type of adhesive whereby there is provided a sufficiently strong adhesive force to hold the paper sheet securely in the file and resists both a strong pull force exerted parallel to a paper sheet surface, and a transverse separation force exerted when the paper sheet is folded back, but which is weak enough to allow separation of the paper from the fastener sheet when the graspable disengaging section is pulled upwardly and away from the file sheet surface by the user.
