20100269720 | METHOD FOR WEB TENSION ADJUSTMENT - The invention relates to methods for web tension adjustment in a processing machine for processing a web of goods, in particular in a shaftless printing press, in which downstream web tension segments are decoupled from an adjustment of the web tension in a first web tension segment defined upstream by a first clamping point and downstream by a second clamping point. To that end, the first clamping point is subjected to a first control instruction, which is generated using a first dynamic element with a non-constant transmission function, and the second clamping point is acted upon by a second control instruction, which is generated using a second dynamic element with a non-constant transmission function. As a result of the provisions of the invention, for decoupling the downstream web tension segments from the web tension adjustment and so forth, it is unnecessary to pilot-control the corresponding downstream clamping points. | 10-28-2010 |

20130167744 | METHOD FOR REGULATING A WEB TENSION IN A PROCESSING MACHINE - A method for regulating a web tension in a processing machine for processing a product web, in particular a shaftless printing press, includes separating a first product-web section from a second product-web section by a delay section. The web tensions in the first and second product-web sections are influenced by first and second actuators, respectively. To regulate the web tension in the first product-web section, the method further includes defining a regulation output value from which an actuating command for the first actuator is derived. An actuating command for the second actuator is defined from the regulation output value and a delay element to decouple the web tension in the second product-web section from the regulation of the web tension in the first product-web section. The delay element delays the effect of the regulation output value on the actuating command for the second actuator by a delay time. | 07-04-2013 |
20130206808 | METHOD FOR REGISTER CORRECTION IN A WEB PROCESSING MACHINE HAVING A DELAY SECTION - A method for register correction in a web processing machine includes leading a product web through at least one delay section and processing the product web by a first processing device. An actuating command is applied to the first processing device to position the product web at an intended position during a web tension change. The actuating command is determined from an actuating command leading to the web tension change and at least one delay term. The at least one delay term delays the action of the actuating command leading to the web tension change on the actuating command for the first processing device by a delay time needed by the product web to pass through the at least one delay section before the first processing device. | 08-15-2013 |
20130235139 | Method for Adjusting the Processing Position of at least one Processing Device not Clamping a Product Web to be Processed - A method for adjusting the processing position of at least one processing device not clamping a product web to be processed within the context of longitudinal register control in a processing machine includes arranging the at least one processing device in a web section which is delimited by two clamping points. The method further includes applying an actuating variable for adjusting the processing position to the at least one processing device within the context of feedforward control, and calculating the actuating variable for adjusting the processing position on the basis of a register deviation expected from a control action of a tensile force control device for controlling the tensile force in the web section. | 09-12-2013 |
20130264410 | Method for Operating a Processing Machine - A method for operating a processing machine, in which a first web section of a product web is delimited by closing a first clamping point and a second clamping point, such that a first web tensile force prevails in the web section. A third clamping point within the first web section is closed, so that a second web section is formed between the first clamping point and the third clamping point. At least one of the closed third clamping point and the closed first clamping point are adjusted by an angle, so that a second web tensile force in the second web section is changed, preferably increased. | 10-10-2013 |
