Definitions

  • the innovation relates to a single-sided corrugated cardboard machine with two intermeshing corrugated rollers, the engagement area of which is fed to the corrugated web to be corrugated, and to a press roller assigned to the corrugated rollers, which presses a cover sheet against the corrugated web lying on the corrugated roller and provided with adhesive on the shaft crests.
  • Such single-sided corrugated cardboard machines are generally known.
  • the corrugated rollers are provided with identical teeth or grooves, equally spaced in the circumferential direction, the depth of the grooves depending on how the corrugation of the corrugated cardboard is to be shaped.
  • the press roll which the cover sheet against the corrugated sheet presses, has a smooth cylindrical circumference. Since the press roller is pressed against the assigned corrugating roller, its distance relative to the axis of the corrugating roller changes periodically as it rolls on the circumference of the corrugating roller. In a position between two adjacent teeth, the press roller axis is closer to the axis of the corrugated roller than in the case of an abutment against a tooth or corrugated tip.
  • the innovation is based on the task of creating a one-sided corrugated cardboard machine which avoids the disadvantages mentioned and, above all, largely suppresses machine noise and requires better vibration behavior.
  • this object is achieved in that the corrugated rollers mesh with one another via helical teeth and the ends of the straight flank lines are offset from one another in the circumferential direction by at least one tooth pitch.
  • the axes of the press roll and the associated corrugating roll are always at the same distance from one another. This is due to the fact that, regardless of the rotational position of the corrugated roller, the press roller always bears against part of a tooth. The notorious stumbling effect is avoided. The result of this is a smoother running of the individual rollers and a greatly improved vibration behavior. In this way, the noise of the corrugated cardboard machine is greatly reduced. The load on the paper is also significantly reduced. Crushing and line punching can be avoided.
  • the corrugated material web is not expected to migrate sideways. Therefore, it can be relatively inexpensive
  • the hammering of the press roller against the corrugating roller is prevented and thus the sensitive disadvantages caused thereby.
  • the production of a corrugated roller with helical teeth is only slightly more complex than that with the conventional straight teeth.
  • Another advantage of the innovation is that corrugated cardboard sheets with an inclined corrugation are arranged in the case of double layers so that the oblique waves cross. In this way you get an increased stiffness in the running direction.
  • arrow teeth In some cases, especially with relatively long corrugated rollers, it can also be advantageous to use so-called arrow teeth.
  • the arrow teeth must also be designed so that the press roll is always in contact with the tip of the teeth at at least one point.
  • the one-sided corrugated cardboard machine shown in FIG. 1 has a first or upper corrugated roller 10 and a second or lower corrugated roller 11 meshing therewith.
  • a corrugated material web 13 is fed to the engagement area of the two corrugated rollers 10, 11.
  • the directions of rotation of the corrugated rollers 10, 11 are indicated by arrows.
  • the corrugated web 14 is located in the corrugations of the corrugating roller 11. It is held here by holding devices, which are not specified in any more detail. For example, these can have guide fingers or work with negative pressure.
  • a glue application roller not shown, which is assigned to the lower corrugating roller 11, applies adhesive to the shaft crests of the corrugated web 14 in a known manner.
  • a press roller 15 is arranged, via a cover sheet 16 is pressed against the corrugated sheet 14 on the corrugated roller 11.
  • Corrugated sheet 14 and cover sheet 16 leave as one-sided corrugated cardboard 17 in the direction of arrow 18 the area of engagement of corrugated roller 11 and press roller 15.
