Definitions

  • the invention relates to a corrugating roll for producing a corrugated web having a corrugation from a material web according to the preamble of claim 1. Further, the invention is directed to an apparatus for producing a corrugated web with at least one such corrugating roll. The invention is also directed to a method of manufacturing such corrugating roll.
  • corrugated board webs or corrugated boards are known to have at least one corrugated web with sinusoidal corrugation.
  • the corrugated web is generally laminated with two opposing webs.
  • Such corrugated webs are usually formed from a smooth or flat material web in a corrugated gap between two rotating corrugating rolls, which have a corrugated profile in the manner of intermeshing gears.
  • the disadvantage here is that the corrugating rolls are set into vibration when using the corrugating rolls, which generally leads to not optimally embossed corrugated webs.
  • a toothed roller can be used whose teeth of different cross-sectional shape and possibly unequal pitch make both an insertion of a strip of material between transverse rods and a displacement and securing these cross bars or the strip of material.
  • the DE 838 416 C discloses a corrugating roll for a spinning machine with a corrugation, which applies a regular pitch in the division.
  • a root circle of the corrugation is displaced eccentrically in relation to a top circle.
  • a different head widths of corrugated corrugating roll can be made from a regularly corrugated bottom roll of conventional design. Surfaces of Riffelfeldern are only eccentric to the original roll axis to grind, whereby the required eccentric displacement of a root circle of the corrugation with respect to the new roll axis and thus different sized head widths of the corrugations can be achieved.
