Definitions

  • the invention relates to a method and a device for continuous Winding up a fibrous web, especially paper, for example Tissue web, the web being guided over a carrying drum and in another Sequence is wound on a winding device.
  • Such methods and devices are used in the production of paper webs known for a long time.
  • a disadvantage of the known devices is that either the contact pressure of the drum on the support roller is such that the drum is driven by the force generated by friction, like this e.g. US 5,611,500 A (Smith) or US 5,845,868 A (Klerelid et al.) show, or if a separate drive of the reel is provided, such as. in DE 197 48 995 A1 (Voith), the contact pressure cannot be exact be set, because there are too many places where you cannot calculate Losses e.g. caused by friction. The specified pressure in the Contact pressure cylinders is set, therefore does not define the actual Contact force between the drum and drum.
  • the aim of the invention is therefore to propose a method and a device, with good controllability even with small contact pressures is given during the winding process.
  • the invention is therefore characterized in that the contact pressure in the nip between drum (winding shaft) and carrier drum is measured without loss.

  • a favorable further development of the invention of the invention is thereby characterized that the drum, preferably throughout Roll-up process, is mounted on force measuring devices. So that becomes a direct and loss-free measurement of the contact pressure possible, including one ensures uniform paper quality over the entire winding process can be.
  • a favorable further development of the invention is characterized in that the force measuring devices in a horizontally displaceable holding device are provided. Thus, a constant direction of force and simple Transmission of the (regulated) pressure force can be guaranteed.
  • An advantageous embodiment of the invention is characterized in that the horizontally displaceable holding device is provided with idlers, which in Guide profiles run, whereby the guide profiles by a vertically running Tape are sealed. So a safe and low-friction shift ensures an exact adjustment of the pressure even with small ones Values.
  • a favorable further development of the invention is characterized in that the endless belt is made of fabric, plastic or steel. In this way can be the cheapest version depending on requirements and environment being found.

This is a very good side Guiding of the belt possible, with no friction losses and no lateral Get lost can occur.
  • a favorable further development of the invention of the invention is thereby characterized in that the carrying drum is mounted on vertical rocker arms and between rocker arms and a fixed counterpart Force measuring device is arranged.
  • the influences of friction and also that Influencing the measurement results by the unbalance of the paper roll can be switched off.
  • the clamping elements can be mechanical, for example as springs or be provided hydraulically or pneumatically, for example as a cylinder.
  • the force measuring device is fixed in the horizontal direction in the horizontal Level of the axis of the support drum arranged, it is ensured that also any weight influences that are always considered separately should be switched off.
  • the arrangement of the force measuring device remains with the fixed carrying drum Always an exact measurement even when changing the reel (reel change) guaranteed in other known systems by the time pressure at Change often due to inaccurate use and the resulting additional unpredictable friction is not ensured.
