20110246127 | Method for Determining at Least One Controller Parameter of a Dancer Position Control Element - A method is disclosed for automatically determining at least one controller parameter of a dancer position control element in a processing machine comprising a dancer, the dancer position of which is registered, wherein, on the basis of the registered dancer position, the rotational speed of a roll is predefined, wherein the at least one controller parameter is determined automatically as a function of a diameter of the roll. | 10-06-2011 |
20110252989 | Automatic Axis Correction Method for Use in a Processing Machine for Processing a Product Web - A method for automatic axis correction in a processing machine for processing a product web, wherein the product web is subdividable into at least two web tension sections, a web tension section being delimited by two clamping points formed as transport or processing devices. An axis deviation of at least one clamping point formed as a processing device is determined. The at least one clamping point is then opened, the axis thereof is automatically corrected on the basis of the axis deviation determined and the clamping point is closed after the axis correction. | 10-20-2011 |
20110307082 | Method for Axis Correction in a Processing Machine and Processing Machine - A method for axis correction in a processing machine, in particular a shaftless printing machine, has at least one axis for processing and/or transporting a material, at least one detection device for detecting a processing parameter and at least one controller device for calculating a controller output variable for axis correction of the at least one axis using the detected processing parameter. The method is implemented iteratively, with the result that feedforward control output values for the feedforward control of the axis correction are determined during an (n+1)-th change in rotation speed of the at least one axis using observation of the controller output variable and/or the processing parameter during an n-th change in rotation speed of the at least one axis. | 12-15-2011 |
20110313574 | Method for Controlling at least One Machining Device which is Coupled to a Machine Tool by Means of an Encoder Signal - A method is disclosed for controlling at least one machining device which is coupled to a machine tool by means of an encoder signal, the machine tool having at least one motion control device. In order to improve the accuracy of the encoder connection, at least one additional variable which characterizes the transport is digitally transmitted from the motion control device to the at least one machining device and is used to correct the encoder signal. | 12-22-2011 |
20120234192 | Method for Controlling a Printing Operation - A method for controlling a printing operation includes detecting at least one position and/or an extent of a register mark located on a printing material by means of a register mark sensor, and using the detected at least one position and/or the extent of the register mark for register control. The method further includes acquiring at least one item of color information by means of the same register mark sensor during the printing operation, carrying out color monitoring with at least the at least one item of color information, and determining a color deviation with respect to a reference value. Furthermore, the method includes defining a threshold value for the color deviation, and outputting a warning and/or automatically making a change from good to poor products when the threshold value for the color deviation is exceeded. | 09-20-2012 |
20120282005 | Method for Controlling a Control Variable for a Processing Machine - A method is disclosed for controlling a control variable for a processing machine, which has driven rollers for transporting and/or for processing a material web, of which rollers at least one is not part of a clamping point. A first control element is pilot-operated based on a second control member according to a control value in order to adjust the at least one driven roller that is not part of a clamping point. | 11-08-2012 |
20120294662 | Method for Controlling the Web Tension in a Web Processing Machine - A method for controlling the web tension of a product web in a web processing machine includes reducing the effects of the web tension control on the web stretch before an impending change in at least one parameter influencing the web tension. | 11-22-2012 |
