  • the invention is pertaining to the field of the methods of production of corrugated constructions with a folded structure used in the capacity of a filler of multilayered panels.
  • the core structure typically is lightweight yet strong, because it has a configuration including hollow spaces as well as interconnected material webs or the like.
  • Typical examples of such core structures include corrugated sheets, honeycomb cellular structures, and the like.
  • Known core structures have a variety of different configurations, and are made of a variety of different materials.
  • folding methods for folding sheet or web materials can be divided into intermittent or discontinuous processes, for example as described in US 5234727, as well as continuous processes.

  • the rolls 29 are made so that their position can be adjusted in an essentially vertical direction. This allows, after the molded core passes through the means 7, to calibrate the height of the crimps produced in the course of molding.
  • the means for such adjustment can be implemented similarly to the means for adjusting the position of the axles of the rolls 6 relative to the brackets 27 in the holding-down device 5, as described herein above.
  • the means 7 for removing the molded core can comprise a supplementary roll 29a arranged within the lower row of the rolls 29 on that side thereof, which faces the relief drum 2.
  • This supplementary roll 29a allows providing a support for the molded core leaving the relief drum 2 and deflecting it into the clearance between the rows of the rolls 29.

  • the crimps When passing from the upper part of the casing 3 to its lower part, at first the crimps will appear, the height of which increases up to its maximum towards the lower part of the casing 3.
  • Such a shape of the surface of the casing 3 is ensured by appropriate adjustment of the mechanisms for mutual angular displacement of the spokes 13 and for mutual displacement of the holders 12 as a result of choosing both the corresponding shape for the inner edge 21 of the central ring 20 and the angular orientation of this ring, as well as due to inclining the side rings 25.
  • the holding-down device 5 is to be placed relative to the relief drum 2 so that the rolls 6 would actually enclose uniformly the casing of the relief drum essentially over half the circumference that forms up the base of the cylinder defining the shape of the casing, i.e., would enclose the entire surface of the casing 3 located between its upper and lower parts as shown in Fig.2.

  • the profile of the inner edge 21 of the central ring 20 is designed so that, at any angular position of the disk 14, the angle between the adjacent spokes is at its maximum within the upper part of the relief drum 2, whereas this angle is at its minimum within the lower part of the relief drum 2.
  • the distance between the adjacent beams 10 attached to the spokes 13 and carrying the holders 12 of the casing 3 changes gradually, in the process of turning the disk 14 through one revolution, from its maximum within the upper part of the relief drum 2 to its minimum within the lower part of the relief drum 2 and then again to its maximum as this one revolution of the disk 14 is being completed.
  • the plates 4 get gradually displaced inside the casing 3 arranged on the holders 12 in the tangential direction from the position, when they define an essentially smooth surface (within the upper part of the casing 3), to the position, when they define a corrugated surface with the maximum height of the crimps (within the lower part of the casing 3), and back again to the position, when they define an essentially smooth surface.
  • the mutual displacement of the plates 4 takes place in the direction that is parallel with the axis of the shaft 15; in this case, the dependency of such displacement from the angle of rotation of the disk 14 is similar to the dependency of the mutual displacement of the plates in the tangential direction, which has been described herein above.
  • the displacement of the plates in the axial direction takes place in the following way.
  • each of the rollers 22 mounted on each one of the outermost sliding members 1 1 of every beam 10 is in contact with the surface of the corresponding side ring 25. Since the rings 25 are arrange on the immovable support having an inclination relative to the vertical plane, in which essentially lies the central ring, the rollers 22 of every beam 10 are periodically moving nearer to one another and then back away from one another during rotation of the disk 14. In doing so, the distance between the adjacent sliding members 1 1 of every beam 10, which carry the holders 12 of the casing 3, gets also changed, because these sliding members are interconnected with each other by means of the pantograph 23.
  • the inclination of the side rings 25 is selected so that the maximum distance between the adjacent sliding members 1 1 would correspond to the maximum distance between the beams 10, whereas the minimum distance between the adjacent sliding members 1 1 - to the minimum distance between the beams 10.
  • Prepreg is fed onto the upper part of the rotating relief drum 2 in the form of sheet material, which is pressed against the surface of the casing 3 by means of the roll 6 of the holding-down device 5.
  • the value of adhesion is selected so that the sheet material 1 , when pressed against the casing 3 by the rolls 6, would not tear off from it, while the surface of the casing 3 is changed, thus repeating the shape thereof, but as soon as the relief drum is turned around through 180°, the corrugated sheet material 1 would detach from the surface of the casing 3 under the influence of its own weight.
  • the corrugated sheet material 1 moves in the direction away from the relief drum, while being at first supported by the supplementary roll 29a of the means 7 for removing the molded core and subsequently entering into the clearance between the rolls 29 of the upper and lower rows of the means 7 for removing the molded core.
  • the above- mentioned clearance is to be set at a predetermined value, so that when the molded core passes between the rolls 29, the height of its crimps gets calibrated.
  • the sheet material can be fed to the relief drum both in the form of a continuous band or as separate predetermined cut-off lengths.
