Sealing device for sealing at least one zone of underpressure or overpressure adjoining a moving surface that includes at least one sealing element, positionable opposite the moving surface to form a front and a rear, with respect to a surface running direction. The sealing device includes a sealing section located at the front and a ventilation section located at the rear. The sealing section is structured to sealingly interact with the moving surface; and the ventilation section is structured and arranged to form a gap with the moving surface that widens in the surface running direction.

The invention claimed is: 1. A sealing device for sealing at least one zone of underpressure or overpressure adjoining a moving surface, comprising: at least one sealing element, positionable opposite the moving surface to form a front and a rear, with respect to a surface running direction, comprising a sealing section located at said front and a ventilation section located at said rear; said sealing section being structured to sealingly interact with the moving surface; and said ventilation section being structured and arranged to form a gap with the moving surface that widens in the surface running direction, wherein said sealing element is pivotally mounted at an end of said ventilation section. 2. The sealing device in accordance with claim 1, wherein said sealing section adjoins said ventilation section. 3. The sealing device in accordance with claim 2, wherein said ventilation section is structured to continuously decrease in cross-section away from said sealing section. 4. The sealing device in accordance with claim 3, wherein the moving surface is arranged in a paper making machine. 5. The sealing device in accordance with claim 2, wherein said gap has a continuously increasing depth in the surface running direction. 6. The sealing device in accordance with claim 1, wherein said sealing section and said ventilation section are composed of a same material. 7. The sealing device in accordance with claim 6, wherein said sealing section and said ventilation section are formed as a single piece. 8. The sealing device in accordance with claim 1, wherein said sealing section and said ventilation section are composed of different materials. 9. The sealing device in accordance with claim 8, wherein said sealing section and said ventilation section are separately formed and secured together. 10. The sealing device in accordance with claim 1, wherein said ventilation section is composed of a porous sound-absorbing plastic. 11. The sealing device in accordance with claim 1, wherein said sealing section is composed of at least one of rubber graphite, polyethylene, and thermosetting plastic. 12. The sealing device in accordance with claim 11, wherein said polyethylene comprises thermoplastic UHMW and said thermosetting plastic comprises phenolic resin. 13. The sealing device in accordance with claim 1, wherein said sealing element comprises a sealing strip. 14. The sealing device in accordance with claim 13, wherein said sealing strip extends transversely to the running direction. 15. A sealing device for sealing at least one zone of underpressure or overpressure adjoining a moved surface, comprising: at least one sealing element, positionable opposite the moving surface to form a front and a rear, with respect to a surface running direction, comprising a sealing section located at said front and a ventilation section located at said rear; and said at least one sealing element being pivotably mounted at an end of said ventilation section to pivot relative to the moving surface to position said at least one sealing element into an operating position, wherein, in said operating position, said sealing section is in sealing contact with the moving surface and a gap is formed between the ventilation section and the moving surface, and wherein said gap increases in the running direction. 16. A sealing device for sealing at least one zone of underpressure or overpressure adjoining a moved surface, comprising: at least one sealing element, positionable opposite the moving surface to form a front and a rear, with respect to a surface running direction, comprising a sealing section located at said front and a ventilation section located at said rear; said at least one sealing element being pivotably mounted at an end of said ventilation section to pivot relative to the moving surface to position said at least one sealing element into an operating position; and a pressure device coupled to said sealing element, wherein, in said operating position, said sealing section is in sealing contact with the moving surface and a gap is formed between the ventilation section and the moving surface, wherein said sealing element is loadable into said operating position by said pressure device, and wherein said pressure device comprises a pressure hose. 17. A sealing device for sealing at least one zone of underpressure or overpressure adjoining a moved surface, comprising: at least one sealing element, positionable opposite the moving surface to form a front and a rear, with respect to a surface running direction, comprising a sealing section located at said front and a ventilation section located at said rear; said at least one sealing element being pivotably mounted at an end of said ventilation section to pivot relative to the moving surface to position said at least one sealing element into an operating position; and a pressure device coupled to said sealing element, wherein, in said operating position, said sealing section is in sealing contact with the moving surface and a gap is formed between the ventilation section and the moving surface, and wherein said sealing element comprises includes a lug extending in a pivot direction, said lug being chargeable via said pressure device. 18. A sealing device for sealing at least one zone of underpressure or overpressure adjoining a moved surface, comprising: at least one sealing element, positionable opposite the moving surface to form a front and a rear, with respect to a surface running direction, comprising a sealing section located at said front and a ventilation section located at said rear; said at least one sealing element being pivotably mounted at an end of said ventilation section to pivot relative to the moving surface to position said at least one sealing element into an operating position; and a pressure device coupled to said sealing element and a spacer, wherein, in said operating position, said sealing section is in sealing contact with the moving surface and a gap is formed between the ventilation section and the moving surface, and wherein a force transmission takes place from said pressure device onto said sealing element via said spacer. 19. The sealing device in accordance with claim 18, said spacer being cambered at least one of a side facing said pressure device and a side facing said sealing element. 20. The sealing device in accordance with claim 19, further comprising a guide structured and arranged to linearly guide said spacer.
