Abstract: 1. Device for inspection of objects (10) with conveying means, comprising several conveyors (12, 14) enabling to run at different speeds, having substantially horizontal surface of conveying to convey the objects (10) about their vertical axis, characterized in that comprising two conveyors (12, 14), which exhibit a mutual lateral separation, a bottom-inspection devices (30, 32) are located within the gap between the conveyors (12, 14). 2. Device according to Claim 1, characterized in that a guiding railing (16) running in the direction of conveying the objects (10) can be placed above the first, more slowly running conveyor (12) to guide the objects (10), wherein the objects (10) on the first conveyor stand on the edge strip between the guiding railing (16) and the edge of the first conveyor (12), and the width of this edge strip is up to approximately 1/3 of the diameter of the objects. 3. Device according to Claim 1 or 2, characterized in that the objects (10) are guided at the side by railings (16, 17) placed above the first or the second conveyor (12, 14) running in the direction of conveying the objects (10). 4. Device according to Claim 2 or 3, characterized in that railing(s) (16, 17) is (are) arranged so as objects are somewhat displaced to the more slowly running first conveyor (12). 5. Device according to any preceding Claim, characterized in that comprising two devices (30, 32) to inspect the bottom spaced at a distance, inside which objects (10) rotate to about 90 degree C or 270 degree C. 6. Device according to Claims 1-4, characterized in that between the first and the second conveyors (12, 14) is placed a transparent moving plate (15) and within the length of said moving plate (15) two devices (30, 32) are arranged for the bottom inspection and the railings (16, 17) are placed so as the objects in the zone of the first device (30) for the bottom inspection stand approximately by 40% of their support surface on one of the conveyors (10) and, approximately by 60% of their supporting surface on the moving plate (15), and in the zone of the other device (32) for the bottom inspection stand approximately by 40% of their support surface on another conveyor (12) and, approximately by 60% of their supporting surface on the moving plate (15). 7. Device according to Claim 6, characterized in that both devices for the bottom inspection are located so close to each other that both 60% zones, monitored by said devices (30, 32) for the bottom inspection supplement each other to the full surface of the bottom of a corresponding object. 8. Device according to any preceding Claim, characterized in that a means (22, 24) for the bottom inspection has a light source (26) and a means (28) of recognition, between which both conveyors (12, 14) are arranged. 9. Process for inspection of objects (10) at which the objects are transported using conveying device, comprising several conveyors (12, 14) running at different speeds and having substantially horizontal surface for conveying the objects (10) and simultaneous rotation of objects around their vertical axis, characterized in that two conveyors (12, 14) are used with lateral separation and a bottom-inspection device (30, 32) is located within the gap between the conveyors (12, 14). 10. Process according to Claim 8, characterized in that during rotation of the objects (10) walls are also inspected (22, 24).
