However, in order to provide a variable cut-off, the print cylinder saddles may have a variety of outer diameters.

Abstract: The present invention is related to a product cutting device for flat material, such as sheets, webs of material or the like. A product folding cylinder rotates about an axis of rotation and has a surface for supporting the incoming material to be cut. A cutting cylinder cooperates with the product folding cylinder and has knife assemblies mounted thereon. Cyclically engageable product seizing elements are assigned to at least one of the product folding cylinder and the cutting cylinder, and are moveable opposite to a sense of rotation of the product folding cylinder. The product seizing elements engage a respective next product's front portion after the cutting operation is terminated.

Abstract: The present invention is directed to an apparatus, such as a folder apparatus of a web-fed printing press, having a printed product delivery with two fan wheel arrangements overlapping each other. An exemplary embodiment includes a mechanism for continuously conveying flat products. The mechanism has devices attached thereto in a timed arrangement for positioning each flat product to be delivered, in its entirety, off a centerline of the fan wheel arrangements prior to the entry of the flat product into a pocket of the fan wheel arrangements.

Abstract: A device for diverting signatures into pockets of at least two slow-down devices is provided. The device includes a set of high-speed tapes (3) arranged downstream of a pair of cutting cylinders (2). A set of diverting belts (6) comprises raised surface portions (6.3) and non-raised surface portions (6.4). The set of high-speed tapes (3) is assigned to the diverting belts (6) to ride on the raised and non-raised surface portions (6.3, 6.4) thereof, thus, periodically altering a signature conveying path (1) of signatures.

Abstract: A printing press including at least one impression cylinder, at least one plate cylinder, a pair of swivel arms corresponding to each plate cylinder and pivotal about a central axis of the plate cylinder, and a transfer cylinder corresponding to each plate cylinder and supported by the pair of swivel arms is disclosed. The swivel arms can be pivoted, so that each transfer cylinder can be moved between a printing position where the transfer cylinder is engaged with the running web and a non-printing position where the transfer cylinder is disengaged from the running web. The transfer cylinders of the present invention also can be commonly adjusted to vary the pressure against a running web.

Abstract: A folder delivery apparatus for single or multiple-stream production includes several delivery systems which are operable in parallel and can be driven independently of one another. During operation of the folder as well as during machine standstill, the delivery systems can be simultaneously shifted automatically or manually through adjustment units, in such a way that while adjustment takes place, the distance between the delivery systems can be set as desired within a minimal and a maximal setting position.

Abstract: In a fan delivery unit of a folder having a plurality of fan discs arranged next to one another on a motor shaft, the fan discs being formed with a plurality of fan blades having fan pockets therebetween, there is provided a device for braking printed products. The braking device includes driven brake shaft disposed parallel to the motor shaft, a plurality of brake rollers corresponding in number to the number of fan discs being mounted on the brake shaft, and a device for driving the brake shaft via the motor shaft selectively in one of two rotational directions. The brake rollers and leading edges of the fan blades are cooperative for delaying travel of a printed product introduced into the respective fan pockets.

Abstract: A method of assuring orderly web travel in a folder includes stamping out of a layered structure formed of mutually superimposed web surface portions, along respective strips thereof, a plurality of tongue-like elements remaining appendant to the web surface portions and projecting through respective holes simultaneously stamped out of the web surface portions so as thereby to hold the web surface portions together at the respective strips thereof; and a device for performing the method.

Abstract: A delivery device in a folding apparatus of a printing press includes a fan wheel or several fan wheels disposed next to one another. The fan wheels are formed of individual fan blades, between which fan wheel pockets are formed. Leading edges of the fan blades have a first profile and trailing edges of the fan blades have a second profile.

Abstract: The invention relates to a deceleration device for folded products, with which folded products following one behind the other are gripped by decelerable transport devices (6, 7) and conveyed. The oppositely arranged transport devices (6, 7) tracing a path of motion (15) are driven by a planetary gearing (16). While planetary gears (21, 22) rotate around a sun gear (23), an instantaneous centre P1 describe a cardioid which, via drive brackets (17, 18 and respectively 55) causes the transport devices (6, 7) to take different speeds during rotation of the planetary gears (21, 22).

Abstract: A folding apparatus for a rotary printing machine with two folding formers arranged one behind the other, nip rollers and cutting cylinders for two paper webs longitudinally folding by the folding formers, as well as deflectors, fans and deliveries for streams of folded products formed of the folded paper webs cut by the cutting cylinders, comprising a pair of first frame members carrying the nip rollers and the cutting cylinders therebetween, a second frame member at least partly disposed between the pair of first frames and intermediate the two product streams, idler means, diverter rollers and delivery devices for the folded products being mounted in cantilevered fashion on both sides of the second frame member.

Abstract: A signature handling apparatus includes a first conveyor which sequentially moves signatures to a discharge station. At the discharge station, the signatures are sequentially transferred to a receiving conveyor. A corrugator assembly is located at the discharge station to stiffen the signatures by forming corrugations which extend between leading and trailing end portions of the signatures. Although the corrugations are only temporarily maintained in the signature, the corrugator assembly is close enough to the receiving conveyor so that a corrugation is maintained in a signature as a leading end portion of the signature moves to the receiving conveyor. Thus, the corrugator assembly is spaced from the receiving conveyor by a distance which is less than the distance between the leading and trailing end portions of the signatures.

Abstract: An improved mopping system useful in cleaning a surface, the mopping system includes in combination a handle having a mop head at one end thereof, a container attached to the handle and holding a dispensable liquid, a valve mechanism for dispensing liquid from the container to a surface, a rotatable absorbent belt for removing liquid from the surface, a scrubber for scrubbing the surface, pressure bar for removing liquid from the absorbent belt and a reservoir associated with the rotatable absorbent belt for storing dirty liquid removed from the floor surface in a container separate from the container carrying the dispensable liquid.
