8 Claims. (01. 281-21) e This invention relates to books and to bookbinding. It has particular utility in the new art of binding books with plastic covers, but it has a more general utility which will appear from the description.

In making books with plastic covers it is frequently useful to bond two .pieces of plastic together on the finished book orwhil'e finishing the book. This is not difficult when the bonding occurs at the free edges of the cover, but becomes increasingly difficult as the attempt at bonding is made closer to the cover hinges, becoming extremely "difiicult and in some cases impossible, at and back of the hinges. It is particularly desirable to employ high frequency induction currents for heat sealing, but when such currents are projected through the whole book, they char and degrade the paper. This has heretofore compelled me to employ less satisfactory methods of heating.

It is an object of this invention to bind books so that electronic heating can be employed without damage.

Another object of the invention is to bind books so that high frequency bonding may be employed even when the current must be applied near or over the binding means that hold the covers on the filler.

The objects of the invention are accomplished, generally speaking, by including an electrode in the bookbinding. In general a metal foil electrode that encloses the back of the filler is satisfactory and offers the least difliculty in application. Electrodes extending through the filler have also been successfully employed but are not generally as satisfactory as the foil electrode.

In the accompanying drawing,

Fig. 1 represents a book in perspective, including a foil electrode;

Fig. 2 is a section on line 22 of Fig. 1; and

Fig. 3 is a vertical section through the back of the binding.

In the figures of the drawing, the numeral Ill refers to the filler of the book, composed of leaves which may be bound in signatures or otherwise in accordance with any practice known to the prior art. The numeral 20 indicates the back of the book, which is of plastic and which is bound over the leaves It by means of bookbinders stitches 36. Covers 2|, 22 are attached to the back 29 by heat bonding at 23. The thermoplastic materials are particularly satisfactory for such bindings.

It is undesirable in most cases to leave the stitching 3B1 exposed, so a strip of plastic 40 is 2 bond'ed'to'the back over the sti't'ching by heat. In order for this bond to be perfect, it is desirable that not only the strip 40 shall be plasticized by the heatbut also the portion of the back 211 which lies beneath the :strip. With ordinary means which apply their heatonly to the outside of the strip 49 this cannot be satisfactorily obtained and when high frequency electrodes 50, 50 are employed, the energy used in' p'enetrating the book is such that the leaves'are liable to be degraded, charred, or even burned before a satisfactory seal canibe made. a

In order to overcome =thi-s dificdl-ty and-make th'e use :of high frequency-electrodes :BU satis'factory-,9I bind within the :back 20 a-foil'electrod'e' 'fi fl.

This is a piece of common foil such as tinfoil or copperfcil, or in cases where cost is no object, silver foil- "This foil can be sewed, 'or stapled with plastic staples inaccordance with the general treatment of the book, or glued, as the case may be.

When the electrodes are brought down upon the strips 40-40, and the high frequency current is turned on, the induction currents pass through and heat the strip 40, the part of back 29 that lies-beneath the strip, and are carried around the leaves of the book by the electrode 60. Thus, the burning that accompanied earlier practice is avoided.

It will be understood that the foil can be as extensive or as limited as desired. as to area. It can be shaped to suit the needs of a particular bonding job. The foil electrodes are the preferred form of the invention, but electrodes of other types can be used as long as they achieve the end of relieving certain portions of the book from the action of the high frequency currents.

As many apparently widely different embodiments of the present invention may be made Without departing from the spirit and scope thereof, it is to be understood that the invention is not limited to the specific embodiments.

What is claimed is:

1. The method of bookbinding that includes the steps of covering the back of the filler with metal foil, enclosing the back of the filler in a back composed of thermoplastic resin, sewing through the back, foil and filler with thread, covering the exposed stitches with a thermoplastic material, and passing high frequency current from side to side of the book through the thread covering material, and the metal foil.

2. The method of bookbinding that includes the steps of covering the back of the filler with an electrically conductive sheet, covering the said sheet with a thermoplastic back, sewing through the back, sheet and filler, covering the exposed sewing with thermoplastic material, and passing high frequency current from side to side of the book through the covering material, the back and the conductive sheet.

3. The method of bookbinding that includes the steps of covering the back of a filler with an electrically conductive sheet covering the sheet with a thermoplastic back, binding the book with means penetrating filler and thermoplastic back, and passing high frequency current from side to side of the book through back and sheet around the filler.

4. A book including a filler, an electrically conductivesheet about the back of the filler, a

thermoplastic back for the book, and binding means, penetrating the back and filler, bonded to the thermoplastic back by the thermoplasticmaterial of the back.

5. A book including a filler, an electrically conductive idler electrode extending from side to side of the filler, a thermoplastic back enclosing the electrode and the back of the filler, sewing means extending through the back, electrode and filler, and thermoplastic covering, means bonded to the thermoplastic back over the sewing.

6. The method of 'bookbinding that includes assembling a filler with'an electrode extending from side to side thereof, enclosing the back of the filler in a thermoplastic sheet that overlaps the ends of the electrode, passing fastening means through electrode, sheet and filler, covering the exposed parts of the fastening means with thermoplastic material, and applying high frequency heat thereto. 1

7. A book having filler means, a flexible electrode means extending from side totside around the back of the filler, a, cover having a thermo- 4 plastic, welded part overlying the electrode and a bound portion of the filler, and electrically nonconductive binding means binding the cover to the filler.

h 8. The method of binding a book by means including the use of high frequency heat that comprises applying flexible electrode means about the back of the filler, overlapping the'sides thereof and extending substantially throughout the length thereof subjected to high frequency heat, applying thermoplastic cover means to the book with thermoplastic parts thereof adjacent the electrode means, and attaching the cover means to the electrode means and the filler means by electrically non-conductive fastening means, and passing high frequency current from side to side of the book in those areas covered by the said electrode means.
