Abstract

241,786. Wolf, E. W. March 4, 1925. Covers. - Vulcanized-fibre book covers, particularly covers for loose - leaf account books, are made by flanging the edges b, b<1>, b<2>, Fig. 4, of a vulcanized-fibre plate a to produce grooves within which a stiffening panel of pasteboard, wood, or the like is inserted, the space above the stiffening panel and between the flanged edges being then filled with a sheet of pasteboard to produce a flush surface. A covering of glazed paper or cloth may be provided. The cover halves thus produced may be connected to a back member f, Fig. 2, by means of hinges g, which are preferably inserted between the vulcanized-fibre plate a and the stiffening panel, and may be riveted in position. The back f is provided with a covering of vulcanized fibre.
