Abstract
The invention is directed to a continuous belt edge detector system for use in a paper making machine having a continuous belt guide device. The edge detector system comprises a continuous belt having an edge dope with metallic particles therein and an inductive sensor connected to the guide device and adjacent the edge dope. The inductive sensor sends a signal to the guide device indicative of a location of the continuous belt. The guide device moves the continuous belt, e.g., transversely relative to the running direction of the belt within the machine, dependent on the inductive sensor signal.
Claims13
In a paper making machine having a continuous belt guide device, a continuous belt edge detector system comprising:
- a continuous belt having an edge, said edge including an edge dope with metallic particles therein, said continuous belt having a running direction in the machine;
- and
- an inductive sensor connected to the guide device and adjacent said edge dope, said inductive sensor sending a signal to the guide device indicative of a location of said continuous belt, the guide device moving said continuous belt transversely relative to said running direction dependent on said inductive sensor signal.
A paper making machine including at least one of a wet end, a press section and a drying section, said paper making machine comprising:
- a continuous belt having an edge, said edge including an edge dope with metallic particles therein, said continuous belt having a running direction in the machine;
- a guide device to move said continuous belt transversely relative to said running direction;
- and
- an inductive sensor connected to said guide device and adjacent said edge dope, said inductive sensor sending a signal to said guide device indicative of a location of said continuous belt, said guide device moving said continuous belt transversely relative to said running direction dependent on said inductive sensor signal.
A continuous belt in combination with a paper making machine, said continuous belt adapted for one of carrying and contacting a fiber web, said continuous belt having an edge, said edge including an edge dope with magnetically non-permeable particles therein.
