  • the device for keeping signatures in the area is distinguished an outlet gusset of a cutting cylinder arrangement in a folder Rotary printing machine characterized in that close to the transport path of the signatures or several extending substantially transversely to the transport direction of the signatures flat guide belts are arranged, the flat and flat belt surfaces the Form transport path of the signatures delimiting guide surfaces, which are at least on one Side of the transport path of the signatures, but preferably on both sides of the Signature transport paths are arranged.
  • the guide bands for example, are made from Metal, plastic, rubber or another suitable material, can have a width adapted to the particular structure of the folder, which for example, can range from a few cm to 0.4 m.
  • the strenght of the metal strips is also of the respective dimensioning of the Depending on the cutting cylinder arrangement and can be, for example, 0.2 to 2.5 mm.
  • a cutting cylinder arrangement has the advantage that the upstream edges of the tapes even with cutting cylinders with a very small Diameter very close to the cutting area so that the area in which the leading edges of the signatures are not after the cutting process can be kept extremely small.
  • They also offer Guide tapes according to the invention have the advantage that they are due to their own elasticity In the event of a paper jam, give in automatically, causing damage such as this can occur from the beginning, especially with permanently installed guide plates be excluded.
  • the guide bands formed by an endless guide belt which over two on top of each other opposite sides - preferably arranged outside the transport path of the signatures first and second deflection rollers is guided.
  • the top and bottom of the Guide surfaces facing signatures are thereby separated from one another opposite inner sides of the endless guide band formed between them the signatures run through.
  • the first and / or the second guide belt can advantageously at an angle to Transport path of the signatures can be arranged so that there is essentially one funnel-shaped inlet area results in the signatures with their leading edges enter. This has the advantage that the formation of "dog ears" in is particularly effectively avoided.
  • the angle at which the two separate guide belts are arranged opposite the transport path of the signatures can also be adjustable in an advantageous manner, whereby an adjustment different signature strengths, signature formats, substrates and Machine speeds.
  • each is preferably the Guide bands assigned a separate tensioning device, which in the simplest case, can be formed, for example, by a tension spring with adjustable preload, which engages on one or both ends of a guide tape according to the invention and is supported, for example, on the frame of the folder.
  • the tensioning device by means of a lever arm which can be pivoted about a pivot axis by means of adjusting means formed, on which a deflection roller is attached, via which the associated guide band to be led.
  • the adjusting means advantageously include a lever arm a spring-loaded force, for example a spiral pull or a spiral compression spring, and a rotatable control cam assigned to the lever arm which the lever arm supports.
  • the control cam and the spring act in the Way together that the lever arm by turning the control cam out of a first clamping position in which the guide band according to the invention with a predetermined is resilient force is applied, is movable into a second position in which Guide band remains tensionless, and for example by hand over appropriate Hooks or similar fasteners can be attached to the lever arm.
  • the Embodiment described allows the voltage by turning the control cam to change the guide belt so that the device is dependent on one each print job to be processed, for example by manual or also motorized rotation of the control cam can be adapted to the respective conditions.
  • the actuating means by a Pneumatic cylinder acting as a lever arm or an electrical actuator are formed, which the lever arm for tensioning the guide band in a first tensioning position and, For example, to attach the strap end to the lever arm, in a second position pivoted, in which the guide band is in an untensioned state.
  • the tensioning of one or more of the guide bands in Depending on the operating state of the printing press takes place in such a way that the Lever arm automatically into the machine when the press is at a standstill or during an emergency stop second position is pivoted, in which the guide band is not tensioned.
  • This can be used, for example, to thread a new paper web in the area of the Outlet gusset of the cutting cylinder arrangement after a web break or before new print job with a different paper width considerably simplified and In the event of a web break or paper jam in the area of the outlet gusset, the danger of Damage can be significantly reduced.
  • the distance between the Guide bands and the transport path of the signatures is changeable. It can do this
  • the guide belts are mounted eccentrically Deflection rollers or over non-circular, in particular over elliptically shaped Deflection rollers are guided so that by rotating the eccentrically or non-circular pulleys a change in the distance between the Guide bands and the transport path of the signatures is made possible.
  • the twisting the eccentrically mounted pulleys or non-circular pulleys can either manually or via appropriate actuators, for example via Electric motors or pneumatic cylinders automatically and preferably in dependence on the operating state of the printing press, especially depending on the print job and the machine speed.
