Device for regulating the linear stability of a belt

A device for regulating the linear stability of a revolving belt (10) of a transport installation including a control roller (20) which is arranged transversely to a belt running direction and is pressed against the belt (10) and which can be deflected by means of an actuating drive cooperating with a sensor (24) detecting a lateral position of the belt (10), in order, in the event of a lateral drift of the belt (10), to deflect the control roller (20) for the purpose of aligning the belt, the control roller (20) being mounted on an axle (21) which is mounted pivotably in the region of a first edge (11a) of the belt (10) and which is connected and displaceably guided at its second end in the region of a second edge (11b) of the belt (10) by guidance and adjustment means, characterized in that the control roller (20) is arranged on the inside of the belt (10) in a belt loop (22) lying essentially perpendicularly to a transport plane and having high loop-around and is pivotable essentially perpendicularly to the transport plane.
