Definitions

  • the invention relates to an auxiliary drive for former fold rollers according to the preamble of Claim 1.
  • GB 10 286 discloses folding rollers which are driven by pull rollers via a gear become.
  • a folder is known from document EP 0 469 311 A1 known, the drive via intermediate wheels and one Belt drive takes place
  • the invention is based on the object of an auxiliary drive for a former folding roller create.
  • the advantages that can be achieved with the invention are, in particular, that for the An auxiliary drive with a simple design is carried out for the setup and paper web feeding process is.
  • the auxiliary drive can change each time the air pressure of the friction wheel changes Presettable torque transmitted between the two rollers.
  • the auxiliary drive remains in its working position always in frictional engagement with the adjacent two rollers Contact, even if the funnel fold rollers are adjusted at least in their gap width become.
  • a longitudinal folding device 01 of a web-fed rotary printing press consists of a Folding former 02 to be driven on both sides at the level of the former 03 Rollers 04; 06, in particular funnel fold rollers 04; 06 and one in the production direction
  • a a material web 10 for example a paper web 10 or one Paper web strand at a distance b pair of rollers 07; 08, especially pull rollers 07; 08.
  • the pull rollers 07; 08 are on their shaft journals 09; 11 in respective side frames 12, e.g. B. each by means of bushings 15 and by means of each of a shaft-fixed drive wheel 20, for. B. about a not shown Gear train can be driven.
  • Each of the friction wheel drives 21; 22 has a friction wheel 23, which acts as a tire 23 is trained.
  • the friction wheel 23 is rotatably on a shaft 24, in particular one Hollow shaft 24 is arranged, both with a frame-fixed rotary entry 26 and communicates with the interior 27 of the tire 23.
  • the hollow shaft 24 is at one end in a bearing 28 two to each other articulated arms 29 adjustable in angle; 31 arranged.
  • the free ends 32; 33 the articulated arms 29; 31 are each on the pin 13; 09 of the rollers 04; 07 stored.
  • the auxiliary drive it is on the tire 23 effective diameter e of the roller 04 to be driven; 06, d. H. the funnel folding roller 04; 06 at its end 18 smaller than the effective diameter f on the tire 23 driving roller 07; 08, d. H. the pull roller 07; 08.
  • a between the two rollers 04; 07 or 06; 08 by the friction wheel drive 21; 22 to transmitted torque can be limited and preset by the tire 23 via a pneumatic directional control valve and the rotary inlet 26 with compressed air is supplied to a defined pressure and thus the outer diameter of the tire 23 is changeable.
  • the auxiliary drive is by means of compressed air supply by the not shown Pneumatic directional control valve switched on in particular when a paper web 10 is drawn in. After the paper web feeding process is completed, the Pneumatic directional control valve switched to ventilation, so that the tire 23 due to its Residual stress assumes its original position in the rest position C.
