Abstract
One type of bookbinding strip consists of a male strip with plural flexible studs projecting therefrom and a female strip with complementary holes and grooves in the outer surface thereof extending from each hole. The studs are inserted through holes in the punched paper, then through the holes in the female strip. The present invention compresses the strips toward each other with the paper therebetween and then, upon manual actuation of a lever, causes blocks carrying rollers to bend 90.degree. the portion of the studs projecting beyond the female strip, 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.
