BOOK AND METHOD OF BINDING Filed Jan. 18, 1954 lNV TOR WW. /W M1 Patented July 31, 1934 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to an improved book and method of binding the book. The method is particularly adapted for re-binding books. The necessity for economical and satisfactory re-binding is present in public libraries and similar institutions. The present method insures a stable re-bound book with all the advantages of the binding of a new book.

This improved method of binding eliminates several objectionable features of the previous rebinding method. In the old method when a book needs rebinding the cover is removed, and the book as then formed is compressed or tapped out to remove the round at the back and the backing joint. Then the book is sanded or cut at the back which removes the material of the pages at the folds which in turn makes the book one of individual pages and also removes the stitching. This operation reduces the back margin. When the book is again sewed the margin is still further reduced. This forms a narrow margin on the inner edge of each page which often makes the reading difficult. The original margin of the sewing fold is thus destroyed and a new one established. New perforations are needed for stitching in the old method and the re-bound book when opened can not be opened flat for comfortable reading especially with the narrow margin at the sewing fold.

My invention corrects these faults by providing a re-bound book with the original margin at the sewing fold and in which the original perforations for stitching are mended.

The invention is also designed to so strengthen the sewing folds of the sections or signatures that the book can be opened flat and freely to the fold of the section without strain.

The invention also provides a book in which the strain at the sewing folds is minimized and the pages will not crease or tear down at the sewing fold when constantly turned in use.

The accompanying drawing, as a part of this specification, illustrates the invention with the parts of a thickness that is necessarily exaggerated and with spaces between sheets also exaggerated. In the drawing Figure 1 is an end view of a section consisting of three sheets. Figure 2 is a similar view showing strengthening or bracing strips on the inner and outer faces of the fold of the section. Figure 3 is a perspective view of a section provided with my improved form of strengthening strip. Figure 4 is an end view of the sections assembled and sewed together to form a book. Figure 5 is a perspective view of a short length of my improved binding strip.

In putting my method into effect the sheets 10 are assembled in the usual way to form a section 11. The sewing fold 12 is provided with a strip 13 on the back of the fold. This strip is pasted on and it is usually a strip of paper gummed on one side. I may also paste a strip of the same kind at 14 on the inside of the fold. The sections with their pasted strips are then assembled as shown in Figure 5 and stitched as at 15 to assemble the sections into book form.

The strip 13 of paper or other suitable material is provided with an uneven edge 16. The edge is preferably serrated or scalloped. This eliminates a straight edge which straight edge would cause a strain at the bending edge which eventually creases and breaks or tears the page under repeated bending in use. The serrated edge provides a fold or bend that is not against a sharply defined straight edge and a fuller or rounded bend takes place causing no break or tear in the paper page. I A book sewn through with my strengthening of the sewing folds of the sections allows the book to open flatly and freely to the fold of the section without strain and the original margin of the sewing fold is preserved. The old line of stitching can be used in a re-bound book as the reenforcing strips mend the original perforation of stitching.

While the method and construction are particularly adapted to re-binding books, it will be evident that they may be employed in the original binding if desired.

While I have shown in the drawing strengthening strips on the inner and outer folds of the section, it will be evident that I may use these strips on each sheet or fold of a section, distributing them through the sections as the particular circumstances require.

I claim:

1. A book section having a folded strip secured over its folded end, said strip having an edge that is uneven relative to the fold.

2. A book section having a folded strip secured over its folded end, said strip having a serrated edge.

3. A book section having strips with serrated edge pasted over the inner and outer folds of the section. a

4. The method of re-binding books which consists in taking the book apart in sections, providing the sections with folded strips at the folds. said strips having serrated edges, then assembling the sections and then sewing them together to again form the book.
