2. Screen belt system according to claim 1 , wherein the outer straps are provided with profilings in the region of their interior sides facing the deflection shafts, and at least one deflection shaft has two drive wheels provided with complementary outer profilings, which wheels are held on a common shaft and cooperate with the profilings of the outer straps in a form-fitting manner.
3. Screen belt system according to claim 1 , wherein the at least one screen belt fabric is configured as a metallic braided fabric.
4. Screen belt system according to claim 3 , wherein the reinforcing profiles penetrate through loops of the braided fabric.
5. Screen belt system according to claim 1 , wherein the screen belt arrangement includes at least two screen belt fabrics arranged side-by-side in parallel, with a lengthwise extending central strap interposed between them, which central strap is connected to the transversely extending reinforcing profiles.
6. Screen belt system according to claim 5 , wherein each screen belt fabric, on an exterior side facing away from the central straps, is connected to a respective outer strap extending in parallel to the central strap.
7. Screen belt system according to claim 1 , wherein the reinforcing profiles have a rod-shaped design.
8. Screen belt system according to claim 5 , wherein the reinforcing profiles are attached to the central strap and/or to at least one outer strap.
9. Screen belt system according to claim 5 , wherein the central strap and the outer straps are provided with profilings in the region of their interior sides facing the deflection shafts, and at least one deflection shaft includes three drive wheels provided with complementary outer profilings, which wheels are held on a common shaft and cooperate with the profilings of the central and outer straps, respectively.
10. Screen belt system according to claim 1 , wherein at least the outer straps are provided with additional cams in the region of their exterior side located opposite the interior side.
11. Screen belt system according to claim 5 , wherein the transversely extending reinforcing profiles are spread over an entire width of the two screen belt fabrics.
12. Screen belt system according to claim 1 , wherein the transversely extending reinforcing profiles are spread merely partially over a width of a respective screen belt fabric and are arranged offset in relation to each other in the transverse direction.
13. Screen belt system according to claim 5 , wherein transversely extending support rods are attached to the central strap, which rods reach into the two adjacent screen belt fabrics in equal amounts.
