Abstract
The stitching or stapling heads, which act together in a stitching zone (C) with the supports that carry printed products to be wire-stitched, have a circular orbit. The stitching heads are guided so as to maintain their more or less vertical position during their orbit. Within the stitching zone (C), each stitching head is thus approximately aligned with its respective support and is therefore in the preferred position for driving the staples into the printed products. When the stitching heads encounter the supports, they are pushed back radially inward against the resistance of compression springs. This causes a slight flattening in the orbit of the stitching heads in the stitching zone (C) and slightly prolongs the time available for the stitching heads to act together with the supports in the stitching process.
