The invention claimed is: 1. A device (1) for transporting and supporting a flat, sheet-shaped article (9), said device comprising: at least one support wall (3) having a first side and an opposite second side, the first side of said support wall facing and supporting the article via a support fluid; plural feed openings (21) in said support wall, said feed openings configured to receive the support fluid so that the support fluid is directed to and supports the article (9); plural drain openings (23) in said support wall, said drain openings configured to drain the support fluid, each drain opening being assigned to a corresponding one of the feed openings (21); and a draining chamber (33) common to all drain openings (23) of said support wall and on the second side of said support wall, wherein a support force exerted by the support fluid in an edge area of the article (9) is equal to a support force exerted by the support fluid over a surface in a middle area of the article (9), wherein a drain line (35) proceeds from the draining chamber (33), wherein the drain line (35) is connected to a supply line (31) by way of a pressure increasing device (37), wherein the draining chamber (33), through which support fluid is drawn off, and a supply chamber (39) through which support fluid is supplied, are on the second side of the support wall (3) facing away from the space (8) between the article (9) and the support wall (3), wherein the draining chamber (33) extends over the entire surface of the second side of the support wall (3), wherein the pressure increasing device (37) is connected on an intake side to the draining chamber (33) and on a pressure side to the supply chamber (39), and wherein an inside cross section of each feed opening (21) is larger than the sum of the inside cross sections of the drain openings (23) assigned to the feed opening (21). 2. The device as claimed in claim 1, wherein there are two support walls (3, 5), each of the two support walls (3, 5) being opposite one another and essentially vertical, the two support walls forming an intermediate space (7) for holding and transporting the article (9). 3. The device as claimed in claim 2, wherein a distance between the two support plates (3, 5) is variable. 4. The device as claimed in claim 3, wherein at least one of the two support plates is adjustable transversely to a superficial extension of the at least one of the two support plates in order to vary the distance between the two support plates. 5. The device as claimed in claim 1, wherein the drain openings (23) are each arranged around the feed openings (21). 6. The device as claimed in claim 1, wherein each feed opening (21) in combination with several drain openings (23) forms a group (25), and all the groups are uniformly distributed over an entire surface of said support wall. 7. The device as claimed in claim 6, wherein the groups of feed openings (21) and drain openings (23) are uniformly distributed over the entire surface of said support wall. 8. The device as claimed in claim 1, wherein the support fluid is supplied directly via the feed opening (21) to a space on the first side of said support wall by a supply line (31). 9. The device as claimed in claim 8, wherein one supply line (31) is assigned to each feed opening (21) for supply of support fluid. 10. The device as claimed in claim 1, wherein the pressure increasing device (37) is a pump. 11. The device as claimed in claim 1, wherein the support fluid has a constant pressure over the entire surface of the article (9). 12. The device as claimed in claim 1, wherein the pressure of the support fluid can be variably set. 13. The device as claimed in claim 1, wherein the support fluid is a gas. 14. The device as claimed in claim 1, wherein the support fluid is a liquid. 15. The device as claimed in claim 1, wherein the support wall (3) is aligned horizontally and wherein the article (9) is located above the support wall (3). 16. The device as claimed in claim 1, wherein the supply chamber (39) extends over the entire surface of the second side of the support wall (3). 17. The device as claimed in claim 1, wherein a plurality of supply lines (31) connect to the feed openings (21) in the support wall (3) and penetrate the draining chamber (33). 18. The device as claimed in claim 17, wherein the plurality of supply lines (31) each have a first end tightly connected to the support wall (3) and a second end tightly connected to an intermediate wall (41) between the draining and the supply chambers (33, 39). 19. The device as claimed in claim 1, further comprising: a pressure sensor (45) in a space (8) between the article (9) and the support wall (3). 20. The device as claimed in claim 19, wherein the pressure sensor (45) is dynamically connected to the pressure increasing device (37) by way of a control (47).
