Method of setting web tensioning

A method of setting web tensioning in a processing machine for processing a material web comprising:

• giving a first control command to a first clamping location to set the web tensioning in a first web-tensioning portion, which is bounded upstream by the first clamping location and downstream by a second clamping location;
• and
• giving a second control command to feed-forward control at least one clamping location which is located upstream of the first clamping location and at least one clamping location which is located downstream of the second clamping location in dependence on the first control command,
• wherein the feed-forward control takes place with different amplitudes and/or different time responses.

A processing machine for processing a material web, comprising:

• a plurality of clamping locations configured to clamp the material web and including at least a first clamping location and a second clamping location located downstream from the first clamping location, the first clamping location and the second clamping location configured to bound a web-tensioning portion of the material web,
• a computing unit electrically coupled to the plurality of clamping locations and configured to set a web tension in the web-tensioning portion, according to a tensioning method including
• giving a first control command to control the first clamping location,
• giving a second control command to feed-forward control at least one clamping location which is located upstream of the first clamping location and at least one clamping location which is located downstream of the second clamping location, and
• wherein the second control command depends on the first control command,
• wherein the second clamping location is not given the first control command or the second control command, and
• wherein the first control command and the second control command are configured to set the web tension in the web-tensioning portion.

• giving a first control command to a first clamping location to set the web tensioning in a first web-tensioning portion, which is bounded upstream by the first clamping location and downstream by a second clamping location;
• and
• giving a second control command to feed-forward control at least one clamping location which is located upstream of the first clamping location and at least one clamping location which is located downstream of the second clamping location in dependence on the first control command,
• wherein all the clamping locations arranged either upstream or downstream of the first clamping location and configured as processing devices are feed-forward controlled in dependence on the first control command.
