It is barbarous to sew more tightly with wire, for in the necessary pulling to pieces to bring them to their former state for binding they are sure to be more or less damaged. Sewing with a large machine using strips of gauze cannot be recommended.
The further treatment of holländert or wire-sewn sheets is dealt with towards the end of the chapter.
Most of the books given to the small binder do not come to him fresh from the printer, but sewn, used or unused, cut open, or as published. The sheets for binding must, as far as possible, be restored to the condition they were in before they were sewn. It is absolutely necessary that they should be made into loose single sheets. This work is called "pulling to pieces." The outer cover is torn off, the thread or wire inside the sheet removed, and the sheets very carefully separated one by one. When they are all pulled to pieces they are pushed open a little at the back, first to one side, then to the other, and scraped with a knife from top to bottom so as to remove all dirt, glue, &c., adhering.
Where the sheets had been cut open and the inner leaves worked out of place, they must be well pushed into the back again. The sheet is lightly held half-open in the left hand, and the leaves are knocked into the back with a long folder or knife.
If sheets are found badly folded they must now be properly re-folded. Any torn places must be repaired. A special chapter ought really to be devoted to this, for repairing and restoring is an art in itself. Here, only the most necessary work can be mentioned.
There are three different kinds of tears: tears in the print, in the margin, and in the back. The first may be torn with slanting edges; in such a case, both edges must be carefully pasted, fitted to each other, a piece of paper laid over and under, and then well rubbed down. If the tear has not slanting edges, but is clean cut, it is always best to paste the edges likewise and to join the pieces by overlapping very slightly. It always looks better than the patching with strips of paper—a method adopted even by good workmen. The pasting on of pieces of tissue paper is to be condemned.
In cases of repairs like the foregoing, a piece of unpasted tissue paper may be laid on the repaired place and rubbed down, so that any paste exuding cannot do harm, and besides, it will serve to strengthen a weak place. It may be used, however, only on condition that the tint is exactly the same as that of the other paper.
Tears at the margin are repaired by pasting on strips of the same paper or of a kind as near as possible in texture and tint. To make the mend less noticeable, the paper should be torn beforehand, that is to say, by tearing one side of the paper the edge is less sharply defined and appears more like part of the sheet and is hardly perceptible.
Tears in the back (if outside) leaves are mended by pasting them down on to the following inner leaf; afterwards the glue makes this place still stronger. If the middle leaf is likewise torn, a narrow strip is pasted into the back. This may be cut true by the straight-edge if a very narrow strip suffices, but if the tear is here also sideways a piece of torn paper must be pasted on. If there are backs, torn off corners, or the like to be put in, a suitable paper is selected, a piece a little larger than the missing piece cut off the edge of the damaged leaf neatly pasted, the patch laid on slightly overlapping, and well rubbed down under a piece of waste paper. When thoroughly dry, the loose edges of the patch should be carefully torn off so as to slope and taper off nicely.
When all parts are repaired and the sheets again in proper order, the book is pressed for a while between boards.
