  • Publication number: 20120280076
    Abstract: A method for operating a winding device of a processing machine for processing a material web is disclosed. A winding device is provided for winding or unwinding the material web. The winding device is operated to specify a web tension, wherein a switch occurs from a first web tension specification procedure to a second web tension specification procedure during the processing of the material web.

  • Patent number: 7980505
    Abstract: In a method for calculating the diameter of a continuous-material reel on a roller, with which the roller is mounted on a swivel arm that is swivelable about a swiveling axis; the roller rotates at a changeable winding speed, and the continuous material is unwound from the roller and directed to a continuous-material machine, or it is removed from a continuous-material machine and wound onto the roller, the winding speed is set as a function of the web-conveyance speed, and the diameter of the continuous-material reel is calculated in a reel-control system; the winding speed is changed when the swivel arm on which the roller is mounted is swiveled about its swiveling axis during the winding motion; a correction value for correcting the change in winding speed is incorporated in the calculation of the diameter of the continuous-material reel, the correction value being determined within the reel-control system, and a related reel-control system is provided.

  • Publication number: 20100310131
    Abstract: The invention relates to a method for determining a quality standard for a product processed by a processing machine, in particular a printing press, having at least two printing units, in which the processing positions of the at least two printing units relative to one another are determined, and based on the determined processing positions, the quality standard is ascertained.

  • Patent number: 7552678
    Abstract: In a method for registration correction for a multicolor rotary printing press in an acceleration phase, having at least one registration correction device with correction parameters for operation of constant speed, and having a motion controller for controlling the print roller speed, if the registration correction device is acted upon in the acceleration phase by at least one fixed set of the correction parameters, which differs from the correction parameters at constant speed, and/or in the acceleration phase, a correction profile that is modified compared to constant speed is used, and/or information about the presence of the acceleration phase is supplied by the motion controller to the registration correction device, then it can be attained that in both methods, during the acceleration phase, the corrector continues to remain active, and even in this phase, it compensates for registration deviations.

  • Patent number: 7117795
    Abstract: To correct the position of a conveyed item (12) in a conveyance system (10), the deviation of the conveyed item (12) from its target position is detected. If this deviation reveals that a correction is necessary, a suitable correction profile Pi is selected from a plurality of available correction profiles (P1, P2, P3), and the correction is carried out.

  • Patent number: 6945170
    Abstract: A method for register correction in machines for processing webs of material includes providing at least one transport shaft and at least one processing shaft cooperating with the at least one transport shaft, driving the shafts synchronously with one another each by an individual drive mechanism, obeying by at least one shaft a chronological guide shaft function which corresponds to an instantaneous position of a guide shaft, correcting a plurality of register-tracking shafts formed by the transport shafts in accordance with a scan of register marks or the web of material relative to the guide shaft function, effecting only one common scanning for one group of the register-tracking shafts which correspond to one another in term of the register correction, and deriving from the only one common scanning a common correction function that all of the register-tracking shafts of the group obey.

  • Publication number: 20040134364
    Abstract: In order to improve a method for register correction in machines (1) for processing webs of material (2), in particular rotary printing presses, paper processing machines and sheet-fed printing presses, having at least one transport shaft (3, 4) and at least one processing shaft (5, 6, 7, 8) cooperating with it, each of which is driven, synchronized with one another, by its own individual drive mechanism (9) and of which at least one shaft (6, 7) obeys a chronological guide shaft function (12), which corresponds to an instantaneous position (13) of a guide shaft (L), and a plurality of register-tracking shafts (3, 4) are corrected in accordance with a scanning of register marks (14) of the web of material (2) relative to the guide shaft function (12), in such a way that—particularly when there is a large number of shafts to be regulated—it assures a greater degree of synchronicity of the shafts to be corrected and at the same time makes simple startup possible with comparatively little effort and
