ABSTRACT:
A bookbinding apparatus for binding together perforated sheets comprises a first strip, spaced-apart studs extending from the first strip, spaced-apart locking caps extending around each stud, a second strip, spaced-apart first openings extending through the second strip, each first opening being aligned with a corresponding stud of the first strip and each first opening having a size larger than the cross-section of the corresponding stud of the first strip to freely receive the stud, and a locking member formed on the second strip for locking the studs to the second strip, the locking member including second openings, each second opening being located next to and in partial contact with a first opening, and each second opening having a size smaller than the cross-section of the studs at a locking cap but larger than or equal to the cross-section of the studs between locking caps such that the second strip after receiving studs of the first strip with the first openings in the second strip locks the studs of the first strip to the second strip by being slid sideways.
