Sealing strip system and sealing strip

A sealing strip system for sealing a suction zone of a suctioned roll of a machine for producing and/or processing a web of fibrous material, the sealing strip system comprising:

• the sealing strip having a sealing face and a wear volume, which is gradually abraded by tribological contact with the roll during use;
• the sealing strip extending along a longitudinal direction and having a front longitudinal side facing toward the suction zone and a rear longitudinal side facing away from the suction zone;
• one of said front or rear longitudinal sides of the sealing strip having at least one sensor channel formed therein extending over substantially an entire length of the sealing strip;
• a sensor system for detecting a state of wear of said sealing strip;
• an evaluation unit to be connected to said sensor system;
• said sensor system being embedded in said at least one sensor channel formed in said front or rear longitudinal side of the sealing strip and extending within said sensor channel in a longitudinal direction thereof in a region of said wear volume over substantially the entire length of said sealing face of said sealing strip;
• at least one connection for connecting said sensor system to at least one of said evaluation unit or a unit for supplying the sensor system with a medium serving to generate information;
• said at least one connection of said sensor system leading away from said front or rear longitudinal side of said sealing strip at a lower region of said sealing strip distal from said sealing face.
