  • Patent number: 8651020
    Abstract: 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.

  • Patent number: 5572433
    Abstract: A system is disclosed for detecting watermarks or other marks made along a web of paper at regular intervals. The watermarks are detected by a video camera activated by a frame grabbing pulse in a control loop. The video for each frame grab pulse signal is digitized and processed to detect the watermark and to measure its position within the frame. The error between the measured position and a frame reference is used to adjust the value of a parameter (NEWCOUNT) representing the distance or pitch between successive watermarks. This value is in turn used to determine the moment of the next or a succeeding frame grab pulse. All timing is done in terms of measured length of web run by measuring pulses from an encoder. The control loop acts to track variations in the watermark pitch.

  • Patent number: 5404202
    Abstract: The present invention is directed to a precise method of registering images on a photoreceptor belt. At least one coded charge pattern is formed in the photoreceptor belt, outside the image area. A charge sensor is positioned above the belt and in the process direction alignment with the pattern. The sensor has an identical pattern formed on the sensing surface. As the coded pattern advances beneath the charge sensor, a correlation signal is generated when the two patterns are exactly aligned. This correlation signal is used to generate a precisely timed line sync signal which is reproducible through each of the imaging stations to produce registration of the first scan line of each image sequence with a very high degree of accuracy. When two coded patterns and two sensors are used, image skew correction signals are generated and used to correct for skew registration errors.

  • Patent number: 4737904
    Abstract: A standard-length positioning apparatus wherein acceleration and deceleration of a driving mechanism for actuating a mechanism for feeding a material is controlled by a digital positioning mechanism according to a position feedback. Marks marked on the material are read by a sensor during the deceleration of the driving mechanism, and the digital positioning mechanism outputs a signal for stopping the driving mechanism when it receives the read-in output of the sensor while the driving mechanism is being decelerated. When a signal from the sensor is not received by the digital positioning means while the drive is being decelerated, the digital positioning mechanism utilizes feedback pulses of a positioning detector to stop the drive.

  • Patent number: 4542893
    Abstract: An apparatus and method whereby two superposed strips (26, 28) of documents are conveyed in a direction of conveyance (30) toward a downstream workstation. The strips (26, 28) are conveyed over one another in a direction of superposition whereby the leading edges of documents of one strip alternate in sequence in the direction of conveyance with the leading edges of documents in the other strip. A determination and control (190) circuit determines whether the leading edges of documents in one strip are tending to creep up on the leading edges of documents in the other strip due to differing speeds of motion of the two strips. If a creeping condition is determined, the circuit (190) energizes brake (400) whereby the motion of at least one of the strips is at least temporarily retarded.

  • Patent number: 4484522
    Abstract: An automatic register adjustment system for a multicolor printing machine has a computer for remote control of register adjusting devices and computer drivable optical scanners traversably mounted for axial movement with respect to the cooperating plate cylinders so that the axial and peripheral coordinates of register marks engraved on the printing plates are determinable. Before printing starts, the printing plates are automatically adjusted for precise register with respect to each other. The register marks may be placed at any desired position on the printing plates and the reference coordinates are freely programmable since the optical scanners can approach any desired point on the printing plate. The scanners, for example, are reciprocated in synchronism with plate cylinder rotation at a speed generally proportional to the rotational speed of the printing machine so that the axial and peripheral coordinates of the register marks are simultaneously sensed.

  • Patent number: 4264957
    Abstract: Register control apparatus for a rotogravure color printing press positions an adjustably movable web (or cylinder) compensator mechanism to, in effect, adjust the web length between printing roller nips in successive printing decks to correct for printing registration errors. The register control apparatus employs the principle that there is a predetermined position of the compensator mechanism for any given length of web wherein register error is eliminated. The register control apparatus, which is initially provided or programmed with electronic signal information representative of web length and compensator mechanism position (null position) wherein no registration error occurs, also includes electrical devices and circuitry for sensing and electronically processing incoming signal information relative to web speed; direction, magnitude and rate of registration error; and change of position of the compensator mechanism.
