ABSTRACT:
A bookbinding is provided by plastic studs which fit through holes vicinal one margin of each sheet and strips which are fixed to the ends of the studs. The studs may be formed integrally with one or, in alternating arrangement, with both strips and complementary holes formed in the matching strip or strips to receive the stud ends. Excess stud lengths are sheared and headed to lock the strips and interposed sheets in position. Both strips may be apertured and the studs inserted through the holes in the strips and interposed sheets, both ends of the studs being headed. To facilitate handling, strips may be assembled in cartridges or coils, and studs in rods or coils. For thicker books, strips are formed with flanges fitting behind the page margins. Spine concealing tapes and caps fit over or around the spine edges of the sheets.
