<p>A bookbinding strip comprises a male strip (11) with flexible studs (12) projecting therefrom and a female strip (13) with complementary holes and grooves in the outer surface thereof extending from each hole. The studs (12) are inserted through holes in the punched paper (17), then through the holes in the female strip (13). Apparatus compresses the strips toward each other with the paper therebetween and then, upon manual actuation of a lever, causes blocks (62,63) carrying rollers (67) to bend the portion of the studs (12) projecting beyond the female strip (13) through 90<o>, causing these portions to snap into the grooves. Since the grooves on each end of the strip extend toward the middle of the strip, two blocks are used, each moving inward toward the center upon actuation of the lever. <IMAGE></p> |
