Abstract
Apparatus is used with two binding strips, the first having at least four studs projecting therefrom which are flexible and the second having holes complementary to the studs and for each hole a groove extending therefrom toward the center of the second strip. The apparatus moves to a position aligned with holes in a stack of sheets. The second strip is deposited on top of the stack with the holes thereof aligned with the holes in the sheets. The first strip is then raised so that the studs pass through the holes in the sheets and the second strip and pressure is applied forcing the strips toward each other. Blocks then move transversely, bending down the portions of the studs projecting beyond the second strip and snapping these portions into the grooves. The steps are performed sequentially using a single pneumatic cylinder for all but the first-mentioned step.
