  • a roller table consisting of rollers 28; 29, one of three Layers 31; 32; 33 of raw fiber fleece 23 supplied and corresponding to the known methods compressed.
  • a strand of the Raw fiber fleece with its layers 31; 32; 33 is now compressed accordingly fed to a suitable cutting device, here consisting of a pendulum 26 with a cutting edge 25, which cuts off the advancing nonwoven fabric 23 and the assigned cut laminated parts of the fiber lamella 24 to a support table 30, which is directed at an angle of 90 ° to the ascending part of the roller table.
  • Fig. 19 presents an insulating element 34 with a surface coating 35 to which chamfers 36 are assigned to the edges. As shown in more detail in FIG. 20, The coating 35 extends over chamfers 36 to the edges of the Side surfaces 38.
  • the element 34 can have a width of up to 2400 mm and is in length, due to the continuous formatting and coating on the production line, kept variable. It’s rectangular formatted here, but can, according to the technological conditions of the building, each take on a geometric, flat shape.
  • FIG. 20 shows that the fiber course 37 of the fibers of the laminated insulation element 34 is directed perpendicular to the major body axes 39; 39 '.
  • This makes it possible for coating 35 may include fiber shafts 40.
  • the form of embracing the Fiber shafts 40 are shown in FIG. 21.
  • a very large enlargement of one Detail of the coated surface shows that the embracing of the Fiber shafts 40 with a low penetration depth 41 of the coating medium into the Insulating element 35 goes hand in hand and still a homogeneous, gapless Surface coating 35 guaranteed.
  • the intimate connection of the coating material with the cross-sectional areas of the fibers and the properties of the Coating material ensure a tear resistance that matches that of the Insulation material can be compared and pragmatically located at 60 to 80 kPa.
