A gateway and method are disclosed for connecting a data source system to an IT system, having real-time capable middleware and non-real-time capable middleware on a common operating system. An application for communicating via a network protocol is executed on the non-real-time capable middleware which comprises a framework, at least one hardware interface via which the data source system is connected to the real-time capable middleware, at least one hardware interface via which the IT system is connected to the non-real-time capable middleware, and a software interface configured to allow communication between the real-time capable middleware and the non-real-time capable middleware. The gateway is configured to provide, via the framework, predefined software interfaces for individual components of the data source system, which components can be connected to the real-time capable middleware, or for components of the IT system.

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.

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.

A method is disclosed for web tension setting in a processing machine for processing a material web, in particular a shaftless printing press. In order to set the web tension in a first web tension section with a length L which is delimited upstream by a first clamping point and downstream by a second clamping point, the first clamping point is loaded with a first manipulated variable which is produced using a first element with a first transfer function G(s) (G3), and the second clamping point is loaded with a second manipulated variable which is produced using a second element with a second transfer function G(s) (G4), wherein cG(s)=&#x2212;cG(s). Thus, it is possible to keep the speed constant even during the regulation at a fixed or variable point x within the web tension section, wherein x=|c/(c+c)|L lies behind the first clamping point.

A method of setting web tensioning in a processing machine for processing a material web, in particular in a shaftless printing machine, wherein, for the purpose of setting the web tensioning in a first web-tensioning portion, which is bounded upstream by a first clamping location and downstream by a second clamping location, the first clamping location is given a control command, and at least one clamping location which is located upstream of the first clamping location, as seen over the course of the web tensioning, and at least one clamping location which is located downstream of the second clamping location, as seen over the course of the web tensioning, are precontrolled in dependence on the first control command, where the second clamping location is not adjusted.

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.

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.

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.
