Systems and methods for the detection of orientation features on a material web

A method comprising:

• probing, using a sensor device, a sensor zone of the sensor device to detect at least one orientation feature of a material web and at least one light beam spot on the material web, the sensor device comprising an optical sensor element having at least one sensor line, the material web being fed at a material web level in a predetermined travel direction through the sensor zone of the sensor device;
• producing the at least one light beam spot on the material web using at least one light transmitter;
• determining, based on the detection of the at least one orientation feature of the material web, a deviation of the material web within a plane of the material web in the sensor zone of the sensor device;
• and
• determining, based on the detection of the at least one light beam spot on the material web, a deviation of the plane of the material web in the sensor zone of the sensor device from a desired material web level.

A device comprising:

• a controller;
• a sensor device comprising:
• an optical sensor element having at least one sensor line and being configured and disposed to probe a sensor zone of the sensor device and detect at least one orientation feature on the material web and at least one light beam spot on the material web while the material web is being fed in a predetermined travel direction through the sensor zone of the sensor device;
• and
• at least one light transmitter configured and disposed to produce at least a first light beam spot, a second light beam spot, a third light beam spot, and a fourth light beam spot on the material web while the material web is being fed in the predetermined travel direction through the sensor zone of the sensor device,
• wherein the at least one light transmitter is configured and disposed such that the first and second light beam spots are arranged along a desired material web level separated by a first distance in the sensor zone of the sensor device;
• wherein the at least one light transmitter is configured and disposed such that the third and fourth light beam spots are arranged along a web level deviating from the desired material web level and spaced apart by a second distance in the sensor zone of the sensor device;
• and
• wherein the optical sensor element is configured and disposed to register the first and second distances and the controller is configured to determine, based on at least the first and second distances, the deviation of a plane of the material web level from the desired material web level in the sensor zone of the sensor device.

A method comprising:

• registering, using a sensor device, a sensor zone of the sensor device to detect at least one orientation feature of a material web and at least one light beam spot on the material web, the sensor device comprising an optical sensor element having at least one sensor line, the material web being fed at a material web level in a predetermined travel direction through the sensor zone of the sensor device;
• producing the at least a first light beam spot, a second light beam spot, a third light beam spot, and a fourth light beam spot on the material web using at least one light transmitter, the first and second light beam spots being arranged along a desired material web level spaced apart by a first distance in the sensor zone of the sensor device, the third and fourth light beam spots being arranged along a web level deviating from the desired material web level and spaced apart by a second distance in the sensor zone of the sensor device;
• and
• registering the first and second distances using the optical sensor element;
• determining, based on at least the first and second distances, the deviation of a plane of the material web from the desired material web level in the sensor zone of the sensor device.
