Definitions

  • the invention relates to a folding former according to the preamble of claims 1 and 2.
  • DE-AS 11 41 650 describes a folding former with transport rollers for webs.
  • the invention has for its object to provide a former.
  • the advantages which can be achieved with the invention consist in particular in that the paper webs of a paper web strand are automatically fed to the folding unit during the pulling-in process of a paper web into a web-fed rotary printing press.
  • Individual paper webs can be retrofitted at machine speed.
  • the paper webs are each under tension between conveyor belts or transport devices guided. These act on both sides of the outer paper web so that the inner paper webs are entrained by the conveyor belts or transport devices. This avoids a shift of the paper webs to each other and thus a jam in the area of the funnel inlet.
  • the paper webs, also as a strand can be transported to the folding rollers, where they are gripped and fed to the folding unit.
  • the paper webs guided by the tape guide devices have a stabilized running direction, so that lateral migration and consequent consequential disturbances are avoided.
  • the tape guide device according to the invention can also be used for eliminating web run disturbances in the paper web feed or for paper run disturbances during the paper web feed in the fold area.
  • the means of transport are oriented in or approximately in the direction of production.
  • guide side parts are provided on both sides of the lateral boundaries of the former area up to or in the vicinity of a former fold roller.
  • a number of upper and lower transport means arranged one above the other are provided within the boundary of the leading side parts.
  • the upper and lower means of transport can be brought into and out of contact with one another and can be driven optionally.
  • a number of conveyor belts which can be subjected to suction air and point in the direction of the surface of the leading side parts are provided within the boundaries of the leading side parts.
  • the transport means consist of driven or non-driven transport rollers.
  • Lower and upper driven transport rollers, e.g. B. interact or there are upper transport rollers interact with lower suction belts.
  • the means of transport consist of driven drive or conveyor chains.
  • the means of transport can also consist of driven V-belts, flat belts or toothed belts.
  • a cover is expediently provided between the boundaries of the former, which has slots for the lower transport means.
  • Slits are also provided in the surface of the guide side parts, which expose the lower transport means.
  • the guide side parts are each assigned an outer paper guide plate spaced apart from them.
  • slots are provided in the outer paper guide plate to enable the upper means of transport to reach through to the lower means of transport.
  • a paper deflection device which is spaced apart from them and surrounds the lateral boundaries in the form of a shell, is provided along the lateral boundaries of the former.
  • a paper guide device that completely or partially covers this is also provided at a distance from the former area.
  • the paper guide device arranged in the area of the former area expediently has slots in order to enable the upper transport means to reach through to the lower transport means.
  • the outer paper guide plate covering the guide side parts and the part of the outer paper guide device covering the former area are connected or adjoin one another in the region of the lateral deflection elements.
