Excerpt from History of the Government Printing Office, (at Washington, D. C.): With a Brief Record of the Public Printing for a Century, 1789 1881The first process the book passes through after it reaches the bindery is termed smashing i. E., reducing the sheets of a volume, by enor mous, sudden pressure in a powerful toggle-jointed machine, to the smallest possible space, to facilitate its more convenient handling by the sewers, etc.After being properly pressed in the smashing machine, they are sawed out for sewing. The machine for this purpose has a number of circular saws, with teeth projecting about one-eighth of an inch above the top, the books are put up in bunches of six or eight, carefully knocked up evenly on the backs, and passed over the saws, which cut five grooves across the back. They are now ready for sew ing. This is an important part of book-making, and has a great deal to do with the good or bad appearance of the future book, as the work is properly or poorly performed. The operation is somewhat complex and difficult to explain, but consists in securing the several signatures together in proper form, by means of a combination of peculiar stitches, with the aid of a sewing frame to hold the work as sewed. The process is also performed to a certain extent by the aid of machinery. The Wire Book Sewing Machines enjoy a monopoly of a certain class of the work, while certain other classes of the literature issued from the office are sewed exclusively by hand.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
