Besides the large trade binders working mainly by the help of machinery, and producing a great quantity of bound work which is not expected to last long, there also exists in London, Paris, New York and other large cities, a small class of art binders who work throughout upon the principles which have been continuously in use for first-class work ever since about the 5th century. The initial impetus to this school can be traced to William Morris, who himself made some beautiful designs for bookbindings, to be executed both in gold and in blind. Although he probably did not fully appreciate either the peculiar limitations or the possibilities of the art of gold-tooling on leather, nevertheless his genius guided him truly as to the spirit in which the designs should be conceived. The revived art soon reached its first stage of development under the guidance of Mr T.J. Cobden-Sanderson, who may fairly be considered as the founder of the modern school of design for gold-tooling on book-covers, the pre-eminence and individuality of his work in this direction being proved by the number of his imitators. Among the most successful of his pupils is Mr Douglas Cockerell, whose work (Plate, fig. 7) is distinguished by a marked originality of treatment, while it shows a scholarly appreciation of ancient methods. Mr Alfred de Sauty has succeeded in developing a new and admirable style in inlaid leathers, combined with delicate pointille work. A number of women artists, both in England and in America, have already discovered in bookbinding a fitting and lucrative field for their energies. One, Miss Sarah Prideaux, is not only skilled and original in her own work, but she has also given us much valuable literature on her subject. Miss E.M. MacColl may claim to be the inventor of the small curved gold line produced by means of a tiny wheel, for though the possibility of producing such a line in blind was known for a long time, it was rarely used. The graceful curves and lines found on Miss MacColl’s work have been designed for her by her brother, Mr D.S. MacColl (Plate, fig. 8). Miss Joanna Birkenruth recalls the highly decorative medieval binding by her use of jewels cut en cabochon, but set in morocco instead of gold or silver, and there are many others who are working well and earnestly at art binding with delicate skill and taste. Outside the inner circle of professional bookbinders there has grown up a new profession, that of the designer for pictorial book-covers, especially those intended to be shown in colour on cloth or paper. Among notable designers may be mentioned Lewis F. Day, A.A. Turbayne, Walter Crane and Charles Ricketts.

Machine-binding.—The principal types of machine for commercial binding are described below. They are almost all due to American or German ingenuity. It may be noted that, while books sewn by hand on bands have the loose ends of the bands actually drawn through the boards and strongly fastened to them through their substance, no machines for covering sewn books will do this so effectively. All they will do as a rule is to paste down to the inner surfaces of the boards the loose ends of the tapes on which the sewing is done. So that, although it may last a long time if not much used, a “cased” book is likely to slip out of its cover as soon as the paste fixing it perishes. Modern bookbinding machines of all kinds are usually driven by power, and in consequence of the necessary setting of most of them accurately to some particular size of book, they are not suitable for binding books of different sizes; the full advantage of them can only be taken where there is a large edition of one book.

Book-sewing machines (fig. 9) are of two kinds one sews the books on bands, either flat or round, and the other supplies the place of bands by a kind of chain stitch. The band-working machines bring the return thread back by pulling it Sewing. through the upper and lower edges of the back of each section, thereby to some extent weakening each section, but at the same time this weakening can be to some extent neutralized by careful head-banding. The other system, where the band is replaced by a chain stitch, brings back the return thread inside each section; the objection to this is that there is a flattening out of the back of the book, which becomes a difficulty when the subsequent operation of covering the book begins. The sections are sewn continuously in a long line, and are afterwards cut apart. The threads catch into hooked needles and are drawn through holes made by piercers set to a certain distance; a shuttle like that used in an ordinary sewing-machine sews the inner thread backwards and forwards. Each section is placed upon a sort of metal saddle by the hand of the operator, one after the other, the machine working continuously unless the action is cut off or controlled by a foot-lever or pedal. This machine is much quieter to work, and although the inner threads are too bulky to be quite satisfactory, this is not a serious matter like the cutting of the upper and lower edges of the back already described, and, moreover, is probably capable of being either improved away or so minimized that it will become of small importance.

The Martini book-sewing machine, which sews books on tape without cutting up head or tail—a most important improvement— and also forms complete Kettle stitches, will sew books of any size up to 18 in. The needles are straight, and the necessary adjustments for various sizes of books are very simple.

The machine for rounding and backing sewn books requires a rather elaborate and very careful setting of several parts to the exact requirement of each size to be worked. The sewn book with the back glued is caught in a clip and forced between Rounding and backing. two tight rollers, the result being that the hitherto flat back is automatically turned into a rounded shape (figs. 10 and 11). The book is then drawn forward, by a continuance of the onward movement, until it reaches the rounding plate, which is a block of steel with a polished groove a little larger than the size required. This rounding plate moves within a small arc by means of heavy counter-weights, and on the back of the book being strongly pressed against it, it receives the permanent form of the groove cut in it, at the same time a strong grip on each side of the book causes the ledge to rise up along each outer edge of the back. This ledge it is which enables the boards to be subsequently fixed in such a way as to hinge on a line outside the actual and natural boundary of the book. Before the discovery of the possibility of producing this ledge, the boards of books hinged upon a line coincident with the inner edges of the back, the result of which was that when the book was opened there was an invariable tendency to open and pull away the few outer sections of the paper or vellum itself—a destructive and disagreeable peculiarity. These machines are capable, after they are properly set, of rounding and backing about 750 volumes of the same size within an hour.

Fig. 12.—Case-making Machine.

The machine for making cases, or “case” covers (fig. 12), for books is large and complicated, but beautifully effective. It contains altogether over fifty springs, some of which are very small, like watch fittings, while others are large and powerful. The machine is fed with pieces of cardboard cut exactly to the sizes of the required boards, other pieces cut to the size of the back, and a long roll of the cloth with which the cases are to be covered, and when set working the roll of cloth is gradually unwound and glued by contact with a roller, which is drawn along until it reaches a point where the two boards are ingeniously dropped upon it one by one, then on again to where a long arm swings backwards and forwards, at each movement picking up a piece of cardboard for the back and placing it gently exactly upon the glued bed left for it between the two boards already fixed. Next, as the cloth passes along, it comes under the sharp influence of two rectangular gouges which cut out the corners, the remaining side pieces being gradually but irresistibly turned up by hollow raisers and flattened down by small rollers, a very delicate piece of machinery finishing the corners in a masterly way. Then, lastly, an arrangement of raisers and rollers acting at right angles to the last mentioned turn over and press out the remaining pieces of cloth. Of course each piece of cloth is cut across at the proper point before the turning up begins. This machine is capable of producing 1200 cases in an hour of any size that the machine will take.
