A folding apparatus () having at least one conveyor belt () which is used to convey signatures () at least on a section of a path () of the signatures () through the folding apparatus (). The folding apparatus () features at least one monitoring device () with which the conveyor belt () is associated. The monitoring device () contains a detector () for radiation () scattered from at least a part () of the conveyor belt (). The condition of the conveyor belt () can be determined and classified in an advantageous manner so that the machine operator can receive a signal for timely replacement so as to avoid an unexpected breakage of the conveyor belt ().

Folding apparatus of a web-fed printing press including a conveyor belt monitoring device

A device for perforating material webs by perforating tools accommodated on perforating cylinders and capable of producing perforations on copies in an exactly correct position with respect to cross-folds formed in the copies, the perforation position being adjustable during machine operation, the perforating tools being cooperatively related with associated perforating strips for producing transverse or cross-perforations, includes at least one perforating bar disposed coaxially with at least one of the perforating cylinders, the perforating tools and the perforating strips being accommodated on at least one of the perforating bars, the at least one of the perforating cylinders being adjustable relative to at least another of the perforating cylinders; a folder including the perforating device; and a pin-less folder including the perforating device.

Device for adjusting the phase of perforating devices as a function of the folding mode

A guiding device for copies in a folder of a rotary printing machine includes a guiding material engageable with copies projecting into an outlet wedge formed between copy-guiding cylinders, the guiding material forming a surface of the guiding device facing towards the copies, the surface having a geometry that is changeable, and copy-guiding cylinders in combination with the guiding device, and a folder with copy-guiding cylinders and the guiding device, as well as a guiding device assembly including the guiding device.

Copy-guiding device having a variable geometry

A paddle wheel delivery for flat copies, which are delivered onto a belt surface of a delivery belt, the paddle wheel delivery including at least one paddle wheel formed of two paddle wheel disks mutually adjustable relative to one another. The delivery includes sickle-shaped regions inwardly movable by a relative movement of the paddle wheel disks, for converting a first pocket width of the paddle wheel pockets on the paddle wheels into a second pocket width of the paddle wheel pockets. Also included is a folder including the paddle wheel delivery; and a web-fed rotary printing machine including the paddle wheel delivery.
