Abstract: An apparatus for thread-stitching of folded print products includes a sewing station in which individual print products are stitched along the fold and print products are then sewn together along the spine to form a book block. A pivoting saddle supplies individual print products straddling thereon to the sewing station. A feeder separates folded print products from a stack of folded print products. A feeding arrangement includes a feed path connecting the feeder to the pivoting saddle, and has a feeding end that cooperates with the feeder to supply the individual print products to the feed path and a discharge end that operates to supply the individual print products to the pivoting saddle. The sewing station, as seen from the top, is arranged on the machine frame of the apparatus, between the feeding end of the feeding arrangement and the pivoting saddle.

Abstract: A device for manufacturing thread-stitched book blocks which comprise folded printed sheets has a conveying apparatus which transports the printed sheets astride a stitching saddle into a stitching position and to which the printed sheets are fed. A stitching apparatus is arranged at a lateral spacing from the stitching saddle which can be driven in an oscillating manner and can be supplied with printed sheets by the stitching saddle. The conveying apparatus is controlled in order to change the conveying speed and/or the stitching position of the printed sheets on the stitching saddle, in that the conveying apparatus is drive-connected to a controlled-rotation electric motor which is controlled by a computer-connected controller.

Abstract: A protective device for a printing machine cylinder assures a risk-free flying changeover of printing plates. The protective device includes a rotatable ring that supports a sleeve-shaped cover. The sleeve-shaped cover can be positioned to partially envelop or cover the cylinder at a separation of the cylinder from another cylinder or a roller in the printing machine.

Abstract: A risk-free flying changeover of printing plates may be achieved, by means of a protecting device for a printing machine cylinder. The above is achieved whereby the protecting device is embodied as a rotating ring (08), on which is arranged a sleeve-shaped cover (09) for the partial enveloping of the cylinder (01, 02), at a separation therefrom.

Abstract: A pair of synchronously rotating draw-in devices are placed in contact with an outer layer of a web of material wrapped on a supply roll. The outer layer is pulled between the two draw-in devices. This pulled-in outer layer can them be conveyed to a separate processing station where it can be given a fresh end.
