«Vetches has been produced in the device according to FIG. It has a layer structure of three non-foamed Michigan pieces of material, which is obtained by cutting up a continuous sheet of material, for example a web into pieces of constant length and stacking these pieces (as well as binding the pieces to one another). The construction or "the structure" can furthermore comprise a foamed sheet material of the type shown in FIG of Wlrrae-Isotattone- and Schallabdlchtungseffeklen as well as to improve the appearance can be applied »

The slaughtering materials according to the invention are not based on board, Table or other flat shapes are limited, but they can also have the shape of pillars, posts, supports, columns or the like. Although the material of the above sample a layer structure consisting of three flat materials have, the invention extends entirely to atlgeewln Layer structures that can be used in any desired number of fM Pieces of material are built up.

The most suitable material for the aforementioned flat material of the raw material may be a resin composition made of a thermoplastic resin such as Polyethylene, petypropyrene, polypropylene, polyvinyl chloride etc., one or more copolymers thereof, or a mixture consists of this and 1 to 95 percent by weight of a FOtI material such as calcium sulfite, gypsum or a mixture

contains of this. The most preferable range of the weight percentages of the aforementioned inorganic filler is 10 to 90- / $. However, according to the invention, adding a filler in an amount outside this range does not substantially lower the mechanical strength and moldability of the thermoplastic resin. Also, the grain size of the inorganic filler material to be incorporated in the resin is not particularly limited, but it is preferred that the grain size be smaller than 500 microns.

Furthermore, the invention is not limited to the aforementioned thermoplastic resins, but similar effects can be obtained by using thermosetting resins such as phenol resins, urea carbamide resins and melamine and cyanuric acid amide resins. Other inorganic filler materials are also suitable for the resin, such as powdered zinc oxide, titanium oxide, carbon and limestone.

If one wishes to use a thermoplastic resin copolymer, then one can for example, a suitable amount of ethylenyl acetate (£ VA) add to improve the elastic character of the material In this case, the shock or impact resistance or - strength of the material and thus the mechanical strength of the stratification increased.

FIG. 5 shows an apparatus for producing a third exemplary embodiment of the construction material or construction material according to the invention In this structure, the rotary selector is the same as in the previous structure was included, has been saved. Here becomes a continuous Flat starting or raw material piece made of a synthetic resin

Same or similar type as in the previous first embodiment between a pair of calender rolls 1 and 2 and then passes between a pair of adhesive application rolls 3 and 4, and is finally cut into pieces of constant length one after the other by means of a cutting device 4. Each separated flat piece 6 of constant length is directly to a helper dzw. 7, and the next flat piece of material is placed over the previous flat material piece θ without re-orienting, as can be seen from FIG. al pieces 6 and oil firstly one are joined to the other to form a stack which can be then introduced into the heat or HeISprüheinrichtung 7 · D * r in the above manner stack 13 produced is in an existing one piece or integral layer material 14 transformed, as can be seen from FIG. 7, which has a uniaxial strength, that is to say it is mechanically very strong only with respect to one axial direction; this is done by means of the heat or. Hot pre-oiling direction 7. In this exemplary embodiment of the layer material, the flat starting material or raw material is foamed.

FIG. 8 shows a fourth exemplary embodiment of the layer material according to the invention, which can be achieved by means of the device according to FIG can manufacture · This material has a layer structure that consists of two non-foamed sheet material pieces is built up. äs can furthermore a foamed flat piece of material like the one at ö In Figure 3 include MateHalstück shown, which is also attached to the layering consisting of non-foamed sheet-like pieces of material is bound to one or both of these strata.

Due to the integration of the stack brought about by the warm or hot rung, the resulting layering can be given a new character that the original flat piece of material does not have , Wood, hemp yarn and the like can be used The stack of flat pieces of material and foreign material can be produced in the heating or hot press, it can also be produced in an intermediate section before it is introduced into the heating or hot press

at spiet, as far as the calender rollers 1 and 2, the Kleostoffauforingungswalzen 3 and 4 and the cutting device S are concerned. However, in this device there is the heat or heat provided with the reference numeral 19. HoiBpresse from a group of heating roller pairs The building or construction material of this embodiment has a layer structure which consists of three flat pieces of the same material as in the first embodiment (indicated at 6, 61 and 62 in Figure 12), these three Flat pieces of material are obtained by cutting up a continuous flat piece of material (for example a Bahr) into a continuous length or pieces of equal length and are placed on top of one another with or without reorientation; Furthermore, the layering of the construction material of this embodiment comprises flat pieces of foreign material (indicated at 70 and 71 in FIG. 12) which are inserted so that they come to lie between adjacent flat pieces of the first-mentioned type. Finally, a surface material layer 20 is also bonded to the upper surface of the sheet of material. The sandwich-like stack produced in this way is converted into a one-piece or integral layering, which is done by means of a thermal pressing device 19 at a suitable temperature (preferably between 160 ° C. and 240 ° C.). During this process, the foreign material is deformed or displaced in a wide variety of ways depending on the foamed state of the stacked sheet-like material pieces. This makes it possible to obtain a product which as a whole has a very high mechanical strength. The same materials or parts as mentioned in connection with the fifth embodiment of the invention explained above can be used as the foreign material.

The above composition is treated in the same manner as in the first example to catch "the desired thickness" to a fishy stick.

As has been described above, according to the invention One piece of material is stacked one on top of the other, made of synthetic resin, some of them relating to the direction of rolling or the Feed of the flat material plug can be reoriented so that it is possible according to the invention * one of the layer material To give blaxial or multiaxial character, the contrast to a single flat piece of material of anisotropic character leads to the fact that the layer material has a biaxial mechanical strength or a very high mechanical strength with respect to two or In other cases also in relation to more than two directions

Even if anisotropic flat material pieces made of synthetic resin too be put together in a one-story layering without individual pieces being given a different orientation compared to others, the resulting Schlchtmaierlaf has an extraordinarily strengthened unlaxieJe strength.

If a plurality of flat pieces of material together with flat MeteriatstOeken is put together from foreign material, because the latter between neighboring fluent mater! alstOck · the former Art are inserted, the result is a uniform character, which is the case with the Originally planar materials not connected · »Is, and the

stratification can be impressed by the foreign matter, such as · is the mechanical strength dmm Schichtmaterla * improved.

If, furthermore, a plurality of foiled, flat pieces of material are joined together with flat pieces of material made of foreign material to form a one-piece layering, the latter pieces of flat material being inserted between opposing pieces of material of the former type, the foreign material becomes the flat pieces of material underwent a deformation P or dislocation in the most varied of catfish, which ultimately leads to the effect that the mechanical strength of the layering is made equal in all directions, so that the mechanical strength of the layer material can be increased extraordinarily.
