BINDING OF BOOKS.

Application filed September 15, 1921. Serial No. 500,852;

To all whom it may concern:

Be it known that I, HENRY TAYLOR, a subject of the King of Great Britain, and resident of South Chingford, London, England, have invented certain new and useful Improvements in and Relating to the Binding of Books, of which the following is a specification.

This invention relates more particularly to the binding of books and has for its object to provide means whereby these books can be forwarded so that they can be cheaply and effectively bound in suitable material such as what is known as a cloth or paper or other cardboard covered case.

In the operation of binding books under a method to which this invention has reference the folded sections are gathered together and the back of the sections are then out off and the remaining single sheets are made rough on the rear edge and then glued, a first lining or strip of crash or gauze is applied. With this arrangement it has been found impossible to satisfactoriiy operate with machines of the kind known as a wireless or perfect binder because of the glue which oozes from the back when pressure is applied at this point. This pressure is necessary to overcome the swell caused by the glue which is applied to back of book.

Gn paper covered books this trouble does not occur as the paper cover takes the place of the second lining or strip and completely covers the back and sides of the book.

According to the present invention the said strip or strips are substituted by a single composite strip of which one side is impregnated with a suitable adhesive and dried, and after this strip has been cemented on the back edges of the leaves or sections forming the book with its impregnated side inwards and its overhanging edges have been folded onto the end papers of the book,

' paste or cement is applied over the overhanging edges of the composite strip and the end papers, and the cover pressed thereon. V

The strip or binding of composite material consists of gauze or like open fabric material impregnated with glue or other suitable adhesive, and to which is applied a covering of thin paper.

An embodiment of the invention is illustrated by the accompanying drawings wherein Figures 1, 2 and 3 show respectively three stages in the binding process.

In Figure 1 the back edges 2 of the book 1 are cut and roughened in the usual way, and to these back edges is applied the cement and then a strip 3 of the special composite material with its previously impregnated side 3 against the book. The extending portions 3 and 3 of the strip 3 are then folded over on the end papers l and 1 of the book, as shown in Figure 2, the end papers 1 and 1 being the sheets adapted to form the lining of the inside of the cover 9, and after a coating of paste or glue is applied over the folded down extending portions 3 and 3 and the end papers 1 and 1 the cover 9 is applied. Figure 3 shows the cover 9 open after the process has been completed. The paste or glue during the process percolates through the paper of the composite strip 3 or lining and serves to moisten the glue or like adhesive with which the gauze or crash of the composite lining is supplied, thus rendering it adhesive so that when the cardboard cover 9 is arranged in position and pressure applied, the cover 9 adheres firmly to the end papers 1* and 1 in the usual manner, and the lining or strip 3 also adheres to the end papers l and l on one side and the cardboard cover 9 on the other, so that the composite lining 3 is firmly positioned between the cardboard cover 9 and the end papers 1 and 1 of the book and is concealed between them.

By means of the foregoing it is possible to bind books cheaply with cardboard covers without wire stitching and without interference with the operation of the ma chine.

The various processes may be carried out by any suitable machinery, and it will be readily understood that by using the composite strip the said processes are reduced in number and less extensive machinery is required than is necessary when two back strips or linings are used in the binding process.

What I claim and desire to secure by Letters-Patent is The method of binding books consisting in applying a suitable adhesive to the back edges of the gathered leaves or folded sec tions sewn or stitched together in the usual way and with end papers adapted to form the inside cover lining, and cementing thereto a single composite strip of fabric and paper of Which one side is previously impregnated with a suitable adhesive and dried, the strip being Wide enough to cover the back edges and extend some distance on to the end papers, and after folding these extending portions on to the end papers applying paste or cement on their outer 10 sides and also on the exposed portions of the end papers, and then pressing the cover thereon, so that such pressure Will cause moisture to pass through the overhanging portions of the strip and moisten the dried adhesive and cause these portions to adhere to the portion of the end papers under them on which the adhesive Was not applied.

In Witness whereof I afiix my signature.

HENRY TAYLOR.
