ABSTRACT:
Method and apparatus for stitching sheets of paper together by means of a hardenable liquid applied to hollow needles which roll with the movement of the stack of sheets moving tangentially to the rotational action of the applicator needles. The needles can be readily arranged in any pattern of applying the hardenable liquid to the stack of sheets, as desired, and the liquid is applied under pressure only at the location of the sheets themselves. Finally, a cover is placed over the stack of sheets with the hardenable liquid not yet set, and thus the cover is automatically glued or adhered to the stack of sheets for a finally neat and complete product.
