System and method for controlling a wrapping process

A round baler comprising:

• a bale chamber in which a rotating bale is wrapped with respective wrapping material;
• a tensioning device configured to remove from at least one supply roller the respective wrapping material during a wrapping process;
• at least one guide roller configured to guide the removed wrapping material during the wrapping process;
• a sensor assembly comprising at least one sensor which is configured to generate sensor data indicative of an actual value for a force resulting from wrapping tension created by the tensioning device wrapping the respective wrapping material during the wrapping process;
• and
• a control unit in communication with the tensioning device and the sensor assembly, the control unit configured to:
• compare the actual value with a target value, the target value derived from a tension-elongation determination that was determined based on at least one preceding wrapping process of the respective wrapping material used on the round baler performing a work process and specific to the respective wrapping material;
• and
• control the tensioning device depending on a deviation determined by the comparison of the actual value and the target value.

A system for controlling a wrapping process of a round bale rotating in a bale chamber of a round baler with an elastic, web-like wrapping material which is drawn off from at least one supply roller and guided during the wrapping process in order to wrap the round bale with pretensioned respective wrapping material, the system comprising:

• a tensioning device configured to remove the respective wrapping material from the at least one supply roller;
• at least one guide roller configured to guide the removed wrapping material during the wrapping process;
• a sensor assembly comprising at least one sensor which is configured to generate sensor data indicative of an actual value for a force resulting from wrapping tension created by the tensioning device wrapping the respective wrapping material during the wrapping process;
• and
• a control unit in communication with the tensioning device and the sensor assembly, the control unit configured to:
• compare the actual value with a target value, the target value derived from a tension-elongation determination that was determined based on at least one preceding wrapping process of the respective wrapping material used on the round baler performing a work process and specific to the respective wrapping material;
• and
• control the tensioning device depending on a deviation determined by the comparison of the actual value and the target value.
