The intertwining of the shaped belts is easy andthe- covering may be laidsurface, which does notit had to be according todoes not require any qualified work or mechanization. Incase of repair of a damaged part of thethe shaped belts by meanscovering it ispossible to exchange of a simplejig.The shaped beltssame by technological processes usual formay be of any length. It is possibleto produce theshaping and machining of elastomers and plastic material- by moulding, extruding, injection, transfer moulding, chipworking and likewise. The shaped belts may be of homogeneousor heterogeneous material, e.g. of laminated material.The face of the belts ishaving straight sides or having the shape of various curvesthe face after putting the belts together formingarranged so that figuresarise ata flat product.BRIEF DESCRIPTION OF THE DRAWINGSThe invention will be further described with referenceto the drawings, wherein Fig. front view of thebasic embodiment of the shaped belt having two face parts,Fig. 2 the ground view of the basic embodiment of the shapedbelt, Fig.each of them having two face parts, Fig.embodiment of the shaped belt,alternative embodiment of the shaped belt.1 shows3 example of intertwining of four shaped belts,4 an alternativeand Fig. 5 anotherEXEMPLIFYING EMBODIMENTSAccording to the exemplifying embodiment, the coveringintersecting shaped belts ;.
