Claims
- 1. A process for laterally sealing at least one excess pressure or vacuum zone adjoining a moving surface in a paper-making machine by way of a sealing device that includes at least one sealing element, the process comprising:arranging the at least one sealing element in a receptacle area of a holder; placing the at least one sealing element relative to the holder against the moving surface, wherein the receptacle area is designed as a clamping receptacle; and acting on the at least one sealing element with a clamping force through clamping surfaces of the clamping receptacle during its movement relative to the holder and in its applied state, wherein the clamping force is greater than a bending force applied by the moving surface to the at least one sealing element.
- 2. The process according to claim 1, wherein the clamping force is at least substantially constant over time.
- 3. A process for laterally sealing at least one excess pressure or vacuum zone adjoining a moving surface in a paper-making machine by way of a sealing device that includes at least one sealing element, the process comprising:arranging the at least one sealing element in a receptacle area of a holder; placing the at least one sealing element relative to the holder against the moving surface, wherein the receptacle area is designed as a clamping receptacle; acting on the at least one sealing element with a clamping force through clamping surfaces of the clamping receptacle during its movement relative to the holder and in its applied state, and varying the clamping force as a function of at least one of, the distance of the at least one sealing element from the moving surface and an application force that acts upon the at least one sealing element for placement onto the moving surface.
- 4. The process according to claim 3, further comprising setting an application force as a function of the ratio between the clamping force and a bending force necessary for adjustment of the at least one sealing element to the contour of the moving surface, once the at least one sealing element has been placed against the moving surface.
- 5. The process according to claim 3, further comprising reducing the application force, once the at least one sealing element has been placed against the moving surface.
- 6. The process according to claim 3, further comprising:selecting the clamping force to be greater than a bending force; and reducing the application force to approximately zero, once the at least one sealing element has been placed against the contour of the moving surface.
- 7. The process according to claim 3, further comprising:selecting the clamping force to be less than a bending force; and reducing the application force to approximately the difference between the bending force and the clamping force, once the at least one sealing element has been placed against the contour of the moving surface.
- 8. A process for laterally sealing at least one excess pressure or vacuum zone adjoining a moving surface in a paper-making machine by way of a sealing device that includes at least one sealing element that is arranged in a receptacle of a holder, the process comprising:subjecting the at least one sealing element to a first force, wherein the first force is sufficient to cause the at least one sealing element to engage an entire contour of the moving surface; and subjecting the at least one sealing element to a second force, wherein the second force is one of a clamping force and a static friction force, wherein the second force is caused by engagement between surfaces of the at least one sealing element and clamping surfaces of the holder, wherein the second force is greater than the first force.
- 9. The process according to claim 8, wherein the moving surface is arranged on a roll jacket.
- 10. The process according to claim 8, wherein the at least one sealing element comprises a wear section and a clamping section made of a different material than the wear section.
- 11. The process according to claim 10, wherein the wear section comprises a slope.
- 12. The process according to claim 8, wherein the at least one sealing element comprises a slope.
- 13. The process according to claim 8, wherein the receptacle contains a pressure tube, the pressure tube being arranged to apply the first force to the at least one sealing element.
- 14. The process according to claim 13, wherein the receptacle contains a pressure tube, the pressure tube being arranged to apply a third force to the at least one sealing element, wherein the third force is greater than the second force.
- 15. The process according to claim 8, wherein the receptacle contains a pressure tube, the pressure tube being arranged to apply a third force to the at least one sealing element, wherein the third force is equal to or greater than the first force.
- 16. The process according to claim 8, further comprising varying the second force.
- 17. The process according to claim 8, further comprising maintaining the second force substantially constant over time.
- 18. The process according to claim 8, further comprising absorbing vibrations of the moving surface while maintaining optimum sealing between the at least one sealing element and the moving surface, whereby a slip-stick effect is thereby prevented.
