Abstract

A cylinder stitching device for binding single sheets for thread sealing, modified French sewing, as well as for wire stitching, includes a stitching cylinder that is controlled by central cams. The stitching cylinder is equipped with stitching heads which can be automatically lubricated, are adjustable, and can optionally be replaced. The production arrangement, attached peripherally to the circumference of the stitching cylinder, is likewise replaceable and automated, so that, by use of the adjusting devices provided for the cylinder stitching device, rapid adaptation to changing processing material as well as high productivity are guaranteed.
