A binding system including a method for binding connected fan folded sheets in which a stack of the sheets is shingled to disclose narrow side surface portions along their spine edges, a layer of pressure sensitive adhesive on a highly flexible backing is adhered to those spine edges and narrow side surface portion after which the spine edges are moved into alignment at a right angle to the side surfaces of the sheets to cause the backing and layer of pressure sensitive adhesive to pleat around the spines of the sheets. The system also includes a novel cover structure which facilitates the method and includes cover plates, the pressure sensitive adhesive and the backing; and a novel device for holding and positioning the sheets during binding.

Binding system for connected fan folded sheets

A cover for the machine-less binding of pages into a booklet comprises a cover having a longitudinal edge of a strip of pressure sensitive tape adhered inside the cover along the central fold line to accept shingled edges of the pages.

Cover for binding sheets

Sheetstock which is too stiff to be dispensed reliably from corner nip feeders is modifed to make it dispensible by forming a diagonal path of relatively low stiffness across each of at least two adjacent corners, preferably all four corners. Such a path preferably is made by forming slits, scores or a line of perforations extending at 45.degree. to the edges of the sheetstock.

Sheetstock dispensable from a corner nip feeder

Loose pages can easily be bound in a cover having a strip of aggressive pressure sensitive adhesive near the fold line by aligning the pages with the outer edge and then rolling the inner edge of the cover and pages to shingle the edges along the adhesive to attach each page.

Backing for binding sheets

A cover for use in binding sheets without use of a machine comprises a sheet of cover with a central fold dividing the cover to a front cover portion and a back portion and a strip of pressure-sensitive adhesive along the fold has a moveable liner.

A sheet for binding loose pages together in pamphlet form comprises a thin flexible sheet having a band of pressure sensitive adhesive coated along one longitudinal edge and protected by a release liner. The sheet permits binding the sheets easily by hand.

Method and sheet for binding pages

A roll of pressure-sensitive tape material which is divided into predetermined lengths by perforations transversely of the length of the tape and each length of tape is separated by a second length of tape and by perforations which provide means for grasping and controlling the length of tape as it is dispensed to avoid contamination of the adhesive on the predetermined length of tape.

Roll of predetermined length strips of pressure-sensitive tape

A binding tape for binding the shingled edges of sheets has a supple tough and flexible nonwoven fibrous backing coated on one surface with a pressure-sensitive adhesive and with a barrier coat to seal the backing on the other surface. A low adhesion backsize is coated on the backing to permit winding or stacking strips of tape. Tabs adhered to the ends of the strips aid in locating the strips in relation to the shingled edges.
