Abstract
Official abstract text for this publication.
A seal assembly for sealing at least one negative or positive pressure zone which adjoins a surface which is perforated and moves in a movement direction in a machine for making paper, tissue or cardboard, has at least one sealing element which lies opposite the moving surface and is arranged in a receptacle which can be moved to change the format of the negative or positive pressure zone. In order to simplify the adjustability of the receptacle in order to position the sealing element, there is a signal transmitter which is connected directly or indirectly to the sealing element and the signal of which can be received on that side of the moving surface which faces away from the sealing element.
First claim
Opening claim text (preview).
What is claimed is: 1. A seal assembly for sealing at least one negative pressure zone adjoining a perforated surface and moving in a movement direction, the seal assembly comprising: a receptacle which is axially movable to change a format of the negative pressure zone; a moving surface; at least one sealing element located opposite said moving surface, said at least one sealing element being arranged in said receptacle; and a signal transmitter connected directly or indirectly with said at least one sealing element, a signal from said signal transmitter being receivable on a side of said moving surface facing away from said at least one sealing element, said at least one sealing element having a bore formed therein, said bore being arranged such that said signal can pass through said bore, wherein said bore is filled with a material permeable to said signal and includes a flushing device.
