Device for the adhesive stitching of printed products

A device for stitching folded printed products having a plurality of sheets, the device comprising:

• a plurality of saddle-shaped supports for the printed products circulating along a closed circulating path running through a stitching region, the printed products being arranged astride the supports and parallel to one another when running through the stitching region and extending essentially at right angles to their circulating direction (U),
• a stitching arrangement having a plurality of stitching heads which meet with the supports in the stitching region and run along with the supports in a section of the stitching region, the stitching heads moving along a closed movement path at essentially the speed of movement (v.sub.B) of the supports and being arranged one behind the other in the direction of movement (B) at a spacing which corresponds to the spacing between adjacent supports;
• each stitching heads having a plurality of penetrating tools for forming passages through the printed products in the region of the fold;
• the stitching arrangement having an adhesive feeder device which is separated from the stitching heads and which feeds adhesive to the penetrating tools, the penetrating tools transferring the adhesive onto the sheets in the passages to produce adhesive stitching;
• and
• wherein the penetrating tools have boring needles having a closed point and pickups on the outer side for picking up the adhesive and transferring the latter to the walls of the passages.
