referring to the drawings , fig1 shows a forming station for wood fiber boards , comprising a cyclone 1 , for supply of glue - coated wood fibers . wood fibers are discharged through a sluice 2 to a dosing bin 3 , for dosage of wood fibers . the dosing bin 3 has means 4 for feeding wood fibers to a conveyor scale 5 . after the conveyor scale 5 the wood fibers pass a spreader 6 , which can be provided with wings , discs , pins or other known means for disintegrating the wood fibers and distributing them over a number of forming rollers 7 . the forming rollers 7 can be adjusted to different angles , depending on the desired thickness of the layer of wood fibers . the forming rollers 7 feed wood fibers on a wire 8 or a conveyor belt for transportation to a pressing station ( not shown ). the drawings show how the devices for supply of wood fibers , up to the forming rollers 7 , are located in line with the wire 8 or conveyor belt , but , the devices may also be located such that the supply of wood fibers are performed perpendicularly with respect to the wire 8 or conveying belt . fig2 shows a more detailed view of the spreaders 6 , followed by the forming rollers 7 and the material web 9 discharged on the wire 8 or conveyor belt . the forming rollers 7 are secured to a common frame 10 , which is arranged at an angle α with respect to the material web 9 . fig3 shows a forming roller 7 , which is arranged transverse to the direction of movement of the material web , and comprises a rotating axle 11 and a number of distributing means 12 . the distributing means 12 are located along axle 11 and consist , in a first preferred embodiment , of a number of oblique , essentially elliptical discs , or similar disc shaped means , which rotate with the axle 11 . the distributing means 12 extend down into the material web 9 . the expression oblique discs also embraces discs which , in fact , are arranged straight on the axle , but which by bending or the like have at least one resulting oblique surface acting on the material web 9 . the axle 11 and the distribution means 12 can be of the type , as disclosed in international patent application no . pct / se95 / 01402 , in which the distribution means 12 are mounted an axial distance from each other for rotation together with the axle 11 , and , around its shorter diameter , are arranged obliquely in relation to the axle 11 , in such a way that they have a circular axial projection . in addition , the distribution means 12 are mounted , in such a way , that the axial distance between adjacent discs overlaps each other in the axial direction , and in addition the discs are inclined at an angle of from about 45 ° to 80 °, and preferably about 60 ° in relation to the axle 11 . during rotation the discs 12 perform an axially backwards and forwards throwing movement of wood fibers inside a imaginary horizontal straight tube . fig4 shows several axles 11 a - 11 f arranged successively after each other at increasing heights from the bottom of the material web 9 , and arranged such that the distribution means 12 of the axis project essentially down into the material web 9 . thus , the particles at each axle , 11 a - 11 f , will , by rotation of the distribution means 12 , spread across the material web 9 to an even layer , 13 a - 13 f , of homogenous distributed particles . fig5 shows a second alternative embodiment of a distributing means 12 , which consists of an elliptical disc provided with openings 14 , through which wood fibers can be transported . the openings 14 can be of a suitable form , but are preferably shaped like spokes 15 or similar means formed between the openings 14 . the spokes 15 can also be turned or shaped in another suitable manner , such that some action by propeller is created , for transportation of wood fibers in a desired direction . the disc can also be provided with protrusions or similar means along its periphery to effect such transportation . fig6 shows a third alternative embodiment of a distributing means 12 , in which , an elliptical disc is provided with recesses to form a propeller blade 16 or similar means , by which wood fibers can be transported in a desired direction . thus , the distributing means 12 according to this embodiment extend only partly around the axle 11 . it is also possible to alter the shape of different distributing means 12 , according to this embodiment , to provide different properties along the axle 11 , in such a way that a desired distribution is obtained . fig7 shows a fourth alternative embodiment of a distributing means 12 , in which an elliptical disc is provided with corrugations 17 or similar surface structure , to convey the wood fibers . the corrugations 17 can also be shaped in such a way that some propeller - type action is created for transportation of the wood fibers in a desired direction . fig8 shows a fifth alternative embodiment of a distributing means 12 , in which , a number of protruding pins 18 or similar structure forms an elliptical planar brush , to convey the wood fibers . fig9 shows a sixth alternative embodiment of a distributing means 12 , in which , propeller blades , 19 a - 19 d , or similar means are arranged along an axle 11 , which in this embodiment has a rectangular cross - section . the outer edge 20 of two propeller blades , 19 a and 19 b , and , 19 c and 19 d , respectively , located on opposite sides , 21 a and 21 b , and , 21 c and 21 d , respectively , of the axle 11 , extend along a common elliptical path . in this embodiment the elliptical path of the propeller blades , 19 a and 19 b , are arranged at an angle with respect to the elliptical path of the propeller blades , 19 c and 19 d . in this manner , it is possible to locate the distribution means 12 closer , and it is also possible to alter the shape of different distributing means 12 , according to this embodiment , to achieve different properties along the axle 11 , in such a way that a desired distribution is obtained . the axles , 11 a - 11 f , are arranged at an angle with respect to the material web 9 , in such a way that several layers , 13 a - 13 f , are formed above each other , the thickness of these layers , and thus the thickness of the resulting material web 9 will be defined by that angle . in the figures the distribution means 12 are directed in the same direction for the different axles 11 , but within the framework of the present invention , they may also be directed in different directions . it is also possible to adjust the inclination of the frame 10 at an angle transverse to the material web 9 , in such a way that the resulting cross - sectional profile of the material web will have a desired shape . by securing the axles , 11 a - 11 f , in the frame 10 , in an adjustable manner , in which each axle , 11 a - 11 f , is individually adjustable vertically , it is possible to influence the thickness of respective layers , 13 a - 13 f . this is especially important for the uppermost located forming roller , to influence the thickness of the uppermost layer 13 f . naturally , the axles , 11 a - 11 f , may also be displaced individually , longitudinally of the material web , to provide different distances between said axles , 11 a - 11 f , or an inclination of respective axles , 11 a - 11 f , and by that influence the distribution of the wood fibers within respective layers , 13 a - 13 f . an additional opportunity to influence the distribution of the wood fibers within respective layer , 13 a - 13 f , is that the axles , 11 a - 11 f , are themselves individually adjustable . thus , each axle , 11 a - 11 f , is shaped , in a known manner , such that the axle during operation has a deflection in a certain direction . although the invention herein has been described with reference to particular embodiments , it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention . it is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims .
