Definitions

  • the invention relates to a device with which flexible bending or elastic materials e.g. to achieve a desired stress-free shape, such as a plan shape can be.
  • Such materials can be constant thick substrates or other rollable materials that are in individual cuts or processed as an endless material web become.
  • paper has in that it is wound into a roll
  • a tendency to curl i.e. a flat part of the material web is under inherent bending stress and therefore the material part upon release of external forces for curvature or Rolling up tends to relieve tension.
  • it can also be necessary to lay a stress-free flat To adjust or edit part of the material so that it is a Occupies the curvature position.
  • the Material in the area of contact with the leveling surface Wrap angle determines which by location a deflection or guide adjacent to the leveling surface is intended for the material.

By turning the disc around the deflection rod and roller can be adjusted to its center be that the paper web either straight without Influenced through or first by the deflecting rod and then deflected by the pulley. Between The paper web is inserted into the deflecting rod and roller Way back that is the multiple of the roller radius or Rod radius is.
  • WO 94/21546 A describes a device for smoothing of flat material in which the flat material between two spaced apart Rolls or rods runs through. Their distance from each other is unchangeable and the paper web contacted only one of the roles respectively Rods. This allows the direction of smoothing to be changed.
