Abstract: A method is provided for monitoring at least one process and for determining fault patterns of faults occurring in the at least one process, wherein a parameter table with characteristic fault patterns is generated for a number of partial processes of the at least one process, wherein the parameter table is generated on the basis of historical sensor data, wherein the historical sensor data describes a number of historical curves which have at least two dimensions and are respectively assigned to a partial process, and wherein the historical curves for each partial process comprise historical OK curves (okay) and historical NOK curves (not okay), wherein the historical NOK curves represent faulty partial processes.

Abstract: The invention relates to a force sensor for measuring a bearing force of a roller deviating a web of material. The force sensor includes a base element on which at least one sensor element is supported. The sensor element has at least one plate which can be elastically deformed by the bearing force and is provided with at least one force transducer. The sensor element is loaded by a pressure piece into which the bearing force is introduced by means of a spring. The spring has a larger range of spring—in the direction of the force—than the elastically deformable plate for the same load. In order to limit the action of the force on the sensor element, an annular abutment is provided, against which the pressure piece can be pressed flat. The abutment is provided around the sensor element.

Abstract: The invention relates to a force sensor (10) for measuring a bearing force (3) of a roller deviating a web of material. Said force sensor (10) comprises a base element (20) on which at least one sensor element (25) is supported. The sensor element (25) comprises at least one plate (40) which can be elastically deformed by the bearing force (3) and is provided with at least one force transducer (42). The sensor element (25) is loaded by a pressure piece (29) into which the bearing force (3) is introduced by means of a spring (32). Said spring comprises a larger range of spring—in the direction of the force—than the elastically deformable plate (4) for the same load. In order to limit the action of the force on the sensor element (25), an annular abutment (35) is provided, against which the pressure piece (29) can be pressed flat. Said abutment (35) is provided around the sensor element (25).
