  • Web-fed rotary printing presses or simply web-fed presses generally have reelstands that are capable of performing a so-called flying reel change.
  • a web of a loading roller is automatically added to an unwinding in a roll changer from a work roll web while production is running, so that both tracks are securely connected.
  • the web of the previous work roll is severed, so that the load roller is the new work role.
  • the old or used work role can either also be removed automatically or manually from the reel changer and replaced, for example, against a new load roller.
  • an early roll change may be required if, in the previous print job and the subsequent print job different types of web or paper types or different web widths are processed.
