The book is now put into the backing boards in the press and glued and backed as described in dealing with the Library Binding.
Two boards, as wide as the book and one-fourth of an inch longer, are cut from heavy tar or mill board. The boards are placed in proper position closely up against the joint projection of the back, and marks perpendicular to the back edges of the boards, are made, indicating the positions of the cords. At each mark and about one-half of an inch from the edge, a hole almost as large as the cords, is made with an awl from the outside, and the projections caused by the awl are trimmed off. Then about one-half inch from these holes, another row of somewhat smaller holes is made. These holes are not in the lines drawn from the edges of the boards, as is shown in Figs. 26 and 27, and are punched from the inside, leaving the projections caused by the awl.
Then a kind of V or trough is cut from each of the first series of holes to the edge of the board, making a place for the cord to lie, Fig. 27.
Now the cords are frayed out and trimmed thin at the ends, and with paste, the frayed portions are twisted to points and inserted down through the first holes and up through the others, a, Fig. 26. When the cords have been drawn tightly and a small amount of paste put around the holes, the ends are again frayed out and spread about the holes, and with a hammer, the board resting firmly on a block, the protruding parts of the board are pounded downabout the cords. After this has been done to all the cords on both sides, the book is left to dry.
The cutting of the edges in boards, is a process requiring the greatest care. A mark is drawn on the white endpaper indicating where the head is to be cut. A tin and a piece of heavy cardboard are placed between the book and the back board. These make a cut-against to protect the cover from the knife. The front board is now drawn down even with the head mark, Fig. 28, and prepared in this way, the book is put into the cutting press.
It is essential to good work that the book be absolutely true in the press, and that the head mark and the top of the board which has been pulled down, be on a level with the top surface of the jaw of the press. The cutting is the same as described under Library Binding, page27.
The book is now removed, the covers are thrown back, and with a try square against the head, a mark is drawn on the endpaper, showing where the foredge is to be cut. With the covers hanging down and a pressing board and one or two thicknesses of cardboard for a cut-against, the book is put into the press and the foredge cut. The foot is cut exactly as was the head.
