However, it only permits the production of products whose Fiber flow is uniform without interruption, based on the major axes of the Element is oriented vertically.
  • Another disadvantage of the known The solution can be seen in the fact that the fabricated from the laminated fiber fleece Element, only along its slats directed transversely to the longitudinal center axis, one has great flexural strength, but one in the direction of its longitudinal center axis reduced resistance to bending.
  • the invention has for its object to provide an insulating element made of mineral wool To make available whose fibers go against the direction of the major axes of the Element are vertically oriented and that with a variable Application has improved physical properties.
  • an insulation element according to claim 1 is proposed.
  • a laminated, oriented vertically in the fiber course trained layer executed one or more times, with layers of the same Material, deviating fiber course or differently structured material in Connected and the layer structure of the element, in the element or repeated several times.
  • the invention finds a very advantageous embodiment in that the element is a has a laminated layer with a vertically oriented grain, based on the extension of their large areas from perpendicular from segment-shaped, repetitive in the layer plane, web-like layer groups is formed, their material structure and composition was not designed in the same way.
  • These products represent an extremely beneficial one Development of an insulation element with consistent application and Further development of the products represented by means of the state of the art solutions mentioned can be produced.
  • the product initially in one In the present layer, groups of one vertically aligned in the course of the fiber are united different material structures with a web-like, vertical Layer structure, with predominantly web-like layers with a different structure Materials are connected and form a flat insulation body.
  • the layers run here, advantageously formed, transversely to the longitudinal center axis, so that a Bridge-like, vertical layer formation repeated in groups is.
  • An insulation element of this structure has previously unknown advantages on.
  • the invention is designed if the web groups of the perpendicular webs are formed from 2 to n times repeating groups of a non-similar structure of the material and its composition: it is advantageous according to the invention and in the sense of the tenor of the solution according to the invention that the repetitive groups, within the framework of the webs, have different strengths and consistencies, webs with high strength being formed in addition to webs with low strength, and the element being large due to the webs with high strength Compressive strengths, great dimensional stability, reduced resilience can be assigned.
  • the webs formed therein with the different strength and density of each other are advantageously laid cross-lattice-like one above the other, there are the advantageous effects that in the area of superposed webs with great strength, continuous lines of force transversely to the large central axes and along continuous lines of force with high fatigue strength as well as high bending and torsional strength of the flat elements are formed.
  • the invention finds an advantageous embodiment in that in the context of claimed process the supplied nonwoven in a multi-layered feeding transport device initiated and guided in the device, one Vertex is moved towards. At the vertex, that is fed multi-layer fiber fleece separated into lamellas. Form the separated slats now assembled layer arrangements of a fleece, the web-like Has lamellar arrangements, the number and material composition the layers form corresponding web-like lamella groups, which during separation be pushed onto the support and removal device and from there a uniform, multi-layer element processed further.
  • the element 12 and 13 show a laminated element a, which is designed with a predominantly vertical fiber orientation.
  • the element a has groups 21 of vertical web-shaped layers 19; 20, which have a different material composition, the groups 21 being able to repeat themselves cyclically or acyclically.
  • the element a can be formed in different thicknesses and is gem.
  • DD Patent 248934 A3 which in its creative application according to FIG. 18 is to find even more detailed explanations, according to the solution, of a patent application which produced the patent.
  • the groups 21 are designed differently in their web-shaped layers 19; 20.
  • the webs 19, 20 are composed differently in their material compositions, the webs 19 being predominantly formed from a fiber material with a vertically oriented, laminated fiber course.
  • the web (s) 20 can be given a different material composition from one another. It is thus possible to arrange the material of the webs 20 running parallel to the longitudinal course of the webs 19, horizontally to the surface 2a, or to use materials that are granular, made of glass fibers or glass fiber fleece. In any case, it has now been possible to imply 21 webs in the individual webs 19 of the web groups, which have a different material design and have an extremely positive influence on the physical behavior of the panels during use, so that the highest possible thermal insulation capacity combined with excellent sound insulation properties and excellent fire protection behavior can be achieved. 14 shows an insulation element of the type according to the invention, in which two elements are brought together as layers 22, 22 ′ at the connection point 2.

  • the half-section shows that the lower layer 22 ', as seen in the plane of the table, has vertically oriented web groups 21 and the plate above it is rotated by 90 ° and web groups 21 running thereto, so that here, as also shown in FIG. 16, a cross-grid-like one Structure of alternately overlapping web groups 21 of webs 19 of vertically oriented fiber course and webs 20 of different material results.
  • the reading specialist now receives the information that an insulation element for absorbing large static loads as well as excellent physical properties, such as the effect of insulation and fire protection behavior, has been created. Only the flexural and tensile strength of this element is excellently secured, whereby, viewed in relation to the large areas, in the transverse course of the forces, zones of high pressure absorption are paired with elastic zones, thus ensuring a considerable static load-bearing capacity of the element in terms of torsional security and resilience ,
  • the integration of webs 19; 20 of different material composition in intersecting web groups 21 can also be realized in elements whose intersecting web course is rotated by 45 ° in the layer structure. This then results in insulation elements with webs 19, 20 and web groups 21 running approximately diagonally to their major axes.
  • Such an embodiment is particularly suitable for square panels which are arranged on horizontal structures.
  • the skilled reader who reads it is clear, without inventive step, that with knowledge of the two-layer designs of the insulation board with layer-like webs 19; 20 and web groups 21 crossing at 90 ° or 45 °, designs of 2 to n layers 22; 22 'are also possible.
  • it is subject to the technological requirements of practice to require insulation elements with such a layer structure, which can then also be manufactured. It is according to the insulation elements.
