  • the winding hardness should mostly be from fall from a certain initial value to a final value, whereby on In the beginning a hard core winding is particularly important.
  • the waste is said to be from the be as even as possible from the first to the last layer. He should be one have certain gradients, i.e. not too strong and not too weak be.
  • the course of the winding hardness should in no case jump points have, e.g. a sudden drop. No in the wrap Radial or destructive or destructive paper web Tangential stresses occur.
  • Winding machines instead of known design, e.g. Wraps where the core is either extremely soft or extremely hard, and where towards the end - around four fifths of the winding diameter - a sharp drop in Winding hardness occurs.
  • the first part that is, the extreme soft or hard core
  • the wrap is not enough is wound hard, there is a lateral displacement of the layers relatively to each other so that the end faces of the finished roll appear frayed and the web edges can be easily damaged.
  • a badly built core (too little or too hard) allows namely no perfect structure of the rest of the winding.
  • the problem is particularly serious for pressure-sensitive papers, e.g. self-copying (SD) papers, the pressing of the Drums with the resulting roll against it
  • SD self-copying
  • the invention has for its object a method and a To design the device for winding a running paper web in such a way that the winding hardness from the beginning to the end of the roll the desired Has course, i.e. that the winding hardness in every moment of the Winding process is under control. In addition, of course machine effort can be kept as low as possible.
  • the paper web predominantly or exclusively by means of a centrally introduced torque, for example is wound onto a reel by means of a central drive and on the emerging role is constantly at least one across the web width extending pressure or squeezing element for squeezing air acts.

  • the invention also provides a device for Winding a paper web into a roll with a reel on which the Web is available.
  • the device according to the invention is characterized in that a central drive predominantly or only the torque required to wind up the reel applies, is provided.
  • the device comprises at least one Squeeze or pressure element that extends across the web width. At least one squeezing element is in the area of the run-up Web arranged on the emerging roll and serves to squeeze Air.
  • the Device has a compensation device that the weight of the emerging role and the drum mainly or alone compensated and which attacks on the outer surface of the roller.
  • the device according to the invention has a feed roller, which in a parallel to the drum and can be brought to this close position.
  • the winding device is the resulting roll after winding around a certain distance, which has a horizontal component, moves and into a Position in which the main winding process is carried out.
  • the invention proposes methods of central drive in the main winding position in a special embodiment of the device, a carriage and a guideway for guiding the carriage during horizontal movement to provide.
  • the Compensation device by appropriate means depending on Roll growth in a vertical direction, for example vertically downwards method.
  • drum and the resulting roll move in a horizontal direction, it is advantageous if the compensation device follows them, is also moved in the horizontal direction.
