Abstract
Sheets are bound to form a bound document by fastening together the sheets and a binding strip. A spacer is applied to a back sheet adjacent to the feet of the fasteners. A wraparound portion of the binding strip is folded around the spine edges of the sheets so that adhesive on the strip contacts the spacer or the back sheet farther from the spine than the feet of the fasteners. The adhesive is affixed to the back sheet. The binding strip includes a spacer adjacent to the heads of the fasteners, protruding above the face-attachment portion at least as far as the heads of the fasteners do.
Claims10
A method of binding a plurality of sheets to form a bound document, the plurality of sheets including a front sheet, a back sheet, and one or more interior sheet(s), each sheet having a respective spine edge, the method comprising:
- using a plurality of fasteners, fastening together the plurality of sheets and a binding strip having a spine-alignment edge, the spine edges of the sheets and the spine-alignment edge substantially aligned, the binding strip including:
- a flexible substrate having an interior surface and an exterior surface, a spine-alignment edge, a free edge opposite the spine-alignment edge and substantially non-perpendicular thereto, a face-attachment portion of the exterior surface adjacent to the spine-alignment edge, and a wraparound portion of the interior surface adjacent to the free edge, wherein a border is defined laterally between the face-attachment portion and the wraparound portion and substantially parallel to the spine-alignment edge;
- an adhesive layer arranged over the wraparound portion;
- and
- a first spacer affixed to the interior surface opposite the face-attachment portion so that a fastener area is defined, the first spacer having a selected thickness;
- wherein the sheets and the binding strip are fastened together by passing fasteners through the sheets and through the fastener area of the binding strip, the fasteners are driven through the fastener area and extend a head thickness above the front sheet and a foot thickness below the back sheet, so that a fastener-foot area is defined on the back sheet;
- applying a back-side spacer to the back sheet adjacent to the fastener-foot area;
- folding the wraparound portion of the binding strip around the spine edges of the sheets, so that the wraparound portion is bent so that the adhesive layer is in contact with the back-side spacer or the adhesive layer is in contact with the back sheet farther from the spine edge of the back sheet than the fastener-foot area;
- and
- affixing the adhesive layer to the sheet edges of at least some of the sheets, and to the back sheet.
