rolling machine

A bookbinding machine at one time used to flatten and consolidate the sections of a book before sewing. It consists essentially of two iron cylinders, each of which is about a foot in diameter. The distance between the rolls can be adjusted by means of a screw. The sections are gathered into packets of anywhere from two to four and placed between tin plates. The number to be rolled at a time depends on the thickness of the sections. The "book" of sections is then passed between the rollers and removed by the workman turning the crank. Before the invention of the rolling machine (in 1827), which was the first machine to be used in the craft of bookbinding, sections were compressed by pounding them with heavy beating hammers. Not all books were suitable for rolling, e.g., old books with a heavy type impression and deep corrugations across the type area; therefore the hammer continued to be used during the remainder of the 19th century, although its use diminished steadily. The modern counterpart of the rolling machine is the BUNDLING PRESS . (83 , 203 , 236 )
