Abstract
A process is provided for binding a plurality of papers arranged together in signatures using an adhesive without requiring the spines of the signatures to be trimmed in order to allow adhesive applied from a single source to contact all of the papers to be bound. A linear array of apertures is cut into each of a plurality of papers. Each paper is folded back on itself to form a signature having two layers of paper with the apertures in each layer at least partially aligned. The signatures are positioned side by side and adhesive is applied concurrently to the spines of all of the signatures, thereby introducing adhesive into the apertures and bonding all of the layers of paper to each other. A backing is contacted with the spines of the signatures to form a cover, thereby providing a bound publication.
Claims12
A method of binding a plurality of papers arranged in sheaves within a backing comprising
- cutting a straight line of apertures in a plurality of papers to remove material therefrom in linear patterns across each paper;
- position said papers in juxtaposition with patterns of apertures of said papers mutually aligned in a straight line and at least partially linearly offset from each other;
- folding said papers along said straight line of apertures to expose layers of material of each of said papers between said apertures for access by an adhesive applicator from one side of said plurality of papers;
- applying an adhesive substance to said exposed layers of material in a single step;
- and
- contacting a backing with said adhesive to bond said backing to said exposed layers of material of each of said papers.
A method of binding a plurality of signatures to form a bound publication comprising:
- cutting a linear array of apertures in each of a plurality of papers, thereby removing material therefrom;
- folding each of said papers perpendicular to said linear array of apertures into a signature of two layers with the apertures of each layer linearly aligned and at least partially linearly offset from each other to expose laminar surfaces of material between said apertures of each of said layers to concurrent access from one side of one of said layers,
- gathering said signatures into side by side relationship;
- concurrently coating an adhesive to said exposed laminar surfaces of said layers of each signature along the line of alignment of apertures therein, thereby introducing adhesive into said apertures to contact laminar surfaces of all of said layers, and
- contacting a backing material with said coated papers, before said adhesive cures to bond said backing to all of said layers of said papers.
A method of binding a plurality of papers each containing printed material to form a bound publication comprising:
- cutting a linear pattern of apertures in a straight line across each paper to remove material therefrom;
- folding each of said papers in half perpendicular to said straight line to form a structure having layers of pages on either side of said pattern of apertures with apertures in each of said layers mutually aligned in a straight line in an overlapping manner to expose laminar surfaces of material between said apertures of each of said layers to concurrent access from one side of each structure, and folding said papers again along said patterns of apertures to form folds cut with at least partially linearly offset apertures;
- positioning a plurality of said folded papers adjacent to each other in symmetrical orientation thereby exposing only the front and back pages on ones of the outermost layers of said papers of all the surfaces of said pages;
- concurrently externally applying an adhesive substance to said folds at the outermost layer of each of said papers along the folds cut with apertures, thereby allowing adhesive to seep through said apertures to contact the exposed laminar surfaces of material between apertures of of said pages;
- and
- contacting a backing with said adhesive before said adhesive dries to bond said backing to said papers and to secure said papers to each other.
