A DEVICE AND A METHOD FOR STABILISING A WEB OR A FILAMENT OF FERROMAGNETIC MATERIAL MOVING IN ONE DIRECTION

摘要

The invention refers to a device and a method for stabilising a metallic object (1) of magnetic material. The metallic object is intended to be transported along a transportation path (2, 3) including a plane (x). The plane includes a transportation direction (x) and is substantially parallel to the longitudinal direction of the object (1) in said path. A sensor (5, 6) is arranged to sense the value of parameter depending on the position of the object (1) with respect to the plane (x). A substantially stationary electromagnetic actuator (7, 8) is arranged to apply a magnetic force to the object in response to the sensed position. The magnetic force includes at least a force component directed transversely to the transportation direction (4) and transversely to the plane (x).
