Abstract
The invention disclosed is directed to a method, an apparatus for manufacturing and apparatus for using a booklet, folder or wrapper comprising two substantially parallel covers (1,2) united with a spine (3) at crease lines (5,6). A strip (4) of adhesive binder is attached to the inside of the spine (3) and extends only between the crease lines (5,6). The strip of adhesive (4) is intended to be activated to provide adhesion between itself and one edge of a sheaf of sheets of material which are inserted between the covers (2,3). Two opposing longitudinal side edges of the (4a, 4b) of the strip of adhesive (4) are united with the respective covers (1,2) before the sheaf of sheets is inserted between the covers (2,3).

Method of producing a folder or wrapper comprising two substantially parallel covers that are united with a spine at inner and outer pairs of crease lines, the spine being substantially perpendicular to the covers, and a strip of binder being rectangular or trapezoidal in cross-section and having top and bottom surfaces and two opposing longitudinal side edges, comprising the steps of attaching the strip at its bottom surface to the spine between the inner crease lines and activating substantially only the two opposing longitudinal side edges of the binder to bind the two opposing longitudinal side edges of the strip to the covers.
Method of producing a booklet, folder or wrapper comprising two substantially parallel covers that are united with a spine at inner and outer pairs of crease lines, comprising the steps of attaching a strip of binder being rectangular or trapezodial in cross-section and having two opposing longitudinal side edges, on the inside of the spine solely between the inner pair of crease lines, uniting the binder with the covers by activating the binder at the two opposing longitudinal side edges of said binder strip to bind the edges to the two covers and pressing the covers of the booklet against the side edges of the binder strip, and binding a sheaf of materials between the covers, whereby the booklet, folder or wrapper is produced.
An apparatus for making a cover for a booklet, said booklet comprising two substantially parallel covers, connected to a spine at formed inner and outer pairs of crease lines, a strip of binder having two opposing longitudinal side edges and being arranged solely between the inner pair of crease lines, and a sheaf of sheets of material located between the covers, said apparatus comprising means for uniting two opposing longitudinal side edges of said binder strip with the covers before a sheaf is inserted therebetween, said uniting means comprising activating means for activating substantially only the side edges of the strip for adhesion and pressing means for pressing the covers of the booklet against the side edges of the strip.
