Abstract
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 sealing device in a receptacle area of a holder, placing the sealing device relative to the holder against the moving surface, wherein the receptacle area is designed as a clamping receptacle, and acting on the 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.
Claims18
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.
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.
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.
