Preparing for Covering.


Nearly all modern books are bound with hollow backs, except where the books are sewn for flexible work or otherwise meant to have tight backs.

Much of the paper used at the present day is so hard, that the binder is almost forced to make a hollow back, in order that the book may open.

The head-band is first set with glue, if worked, by gluing the head and tail, and with a folder the head-band is made to take the same form as the back. This is to be done by holding the book in the left hand with its back on the press, then a pointed folder held in the right hand is run round the beading two or three times to form it; the silk on the back is then rubbed down as much as possible to make all level and even, and the book is allowed to dry. When dry it is pat into the lying press to hold it, and the back is well glued all over; some paper, usually brown, is now taken, the same length as the book, put on the back, and rubbed down well with a thick folder: a good sized bone from the ribs of beef is as good as anything. The overplus of the paper is now to be cut away from the back, except the part projecting head and tail. A second coat of glue is now put on the top of the brown paper and another piece is put on that, but not quite up to the edge on the left hand side. When this is well rubbed down it is folded evenly from the edge on the right side over to the left, the small amount of glued space left will be found sufficient to hold it down; the top is again glued
