ABSTRACT:
A rotational stitching apparatus with separately driven stitching head is used for stitching folded sheets by wire and thread clamping, thread sealing, and loop thread stitching. The drive system permits autarkic stitching heads to be optionally replaced and to be adjusted in correspondence with the product assortment. Each stitching head has a stitching head driveshaft, by means of which it is connected to the stitching cylinder driveshaft 1 or the cylinder axle 37, preferably by way of a gear or the toothed belt. Implementation of various stitching technologies is made possible by additional apparatus disposed peripherally to the stitching cylinder circumference.
