Then,lastly, an arrangement of raisers and rollers acting at right anglesto the last mentioned turn over and press out the remaining piecesof cloth. Of course each piece of cloth is cut across at the properpoint before the turning up begins. This machine is capable of producing 1200 cases in an hour of any size that the machine willtake. The Smyth casing-in machine (fig. 13) pastes the sides of a bookas required and then attaches the cover over all. Cleverly arrangedrollers catch the book, and by a carefully regulated pressure fix thecover in the proper position. There is a jointing-in device which. Fig. 13.—Smyth Casing-in Machine. Scale 1:25.

It will work books from 4 to 22 in. in length and fromi to 3 in. in thickness, and can cover from 10 to 15 books per minute. Here may also be mentioned the Sheridan wrappering machine,which covers magazines and pamphlets ranging from 5 to 12 length at the rate of 40 a minute.
