An assembly for a rotary press is provided including a hub which is suitable for being rotatably mounted about a center axis in a rotary press, a format adaptation sleeve and means for fixing the adaptation sleeve to the hub. The hub and the adaptation sleeve each include a stop surface. The stop surfaces have a frustoconical shape about the center axis, and the fixing means comprise a radial stop element which is suitable for being interposed between the hub and the adaptation sleeve.

A device for catching a torn transport belt, includes a holding device for the transport belt. The holding device has two catching elements between which the transport belt runs, for holding the transport belt firmly therebetween. A first one of the two catching elements has a convex surface facing towards the transport belt, and the second one of the two catching elements has a concave surface facing towards the transport belt. Also included is a device for measuring tension of the transport belt, the tension measuring device being constructed for triggering the holding device when the tension of the transport belt falls below a prescribed value. A folder including the catching device is also provided.

A device for guiding sheet-like copies which are severed from a material web in a cutting nip of a cutting-cylinder pair, including a copy guide disposed in an outlet wedge of the cutting-cylinder pair for gripping leading ends of the sheet-like copies for guiding the copies, the copy guide including revolving transport elements, and actuating drives for displacing the revolving transport elements in a lateral direction so as to adapt the transport elements to different positions and widths of material webs.

Device for guiding flat or sheet-like copies in folders

Device for holding a flexible printing form along the circumference of a printing form cylinder, so that a leading edge of the printing form engages beyond a leading edge of a clamping channel extending across the circumferential surface of the cylinder, comprising at least one resilient holding element secured to an actuatable clamp shaft for fixing a trailing edge of the flexible printing form, said holding element being a spring element that is engageable behind the trailing edge of the printing form with play when the clamp shaft is actuated; a printing form cylinder having the holding device; a printing unit of a rotary printing machine having the holding device; and a printing unit of a rotary printing machine having a printing form cylinder including the holding device.

Device for clamping printing forms in clamping channels of reduced size

A tensioning device for a printing form on a jacket surface of a printing unit cylinder in a printing unit of a rotary printing machine, the printing unit cylinder being formed with a tensioning gap for receiving ends of the printing form therein, a tensioning shaft being received in a bore formed in the printing unit cylinder, the tensioning shaft being held under pretensioning by tensioning elements, includes fluid-loaded cylinders disposed on the tensioning shaft for respectively locking and unlocking a tensioning element on the tensioning shaft, and a separate actuating cylinder for setting an operating pressure of the fluid-loaded cylinders; a printing unit cylinder with the tensioning device; a printing unit with a printing unit cylinder; and a printing unit cylinder cooperating with a transfer cylinder.

In a rotary printing machine, a folder operatable in different folding modes, and having a copy-guiding cylinder to which copies severed from a material web by a cutting-cylinder pair are feedable, the copy-guiding cylinder having a circumferential surface wherein gripping and cross-folding elements are accommodated, includes a device having movable circumferential-surface parts guidable by a respective guide element and, during folding-mode changeovers, selectively extendable into the circumferential surface of the cylinder and retractable between stationary and movable segments of the copy-guiding cylinder which are positionable relative to one another.

Copy-guiding cylinder of a folder

A retainer for firmly holding a printing plate on a plate-carrying cylinder by a hook that engages in an elongated gap formed in the cylinder and is fixedly connected to a tension rod guidable rotatably by drive mechanisms so that it is alignable relatively to two limiting directions in accordance with two limit positions. The drive mechanisms include a piston rod that is supported in a longitudinal bore formed in the cylinder, the piston rod carrying a plurality of pistons distributed over the entire length thereof and including a longitudinal conduit selectively suited for supplying pressure medium for positioning the pistons selectively in two extreme positions.
