  • Rubber blanket plate for clamping onto a cylinder
    Patent number: 7150224
    Abstract: The rubber-blanket plate comprising a carrier plate (2) on which functional layers (3) are arranged. The functional layers (3) include a covering layer (4), a woven-fabric layer (5) and a compressible layer (6). At the two ends of the rubber-blanket plate (FIG. 4a), only the ends of the covering layer (13) extend to the carrier plate (2), whereas the functional layers end before that. As a result, effective protection of the functional layers (3) is attained, and it is possible to use a relatively narrow channel (FIG. 4a) in the printing press cylinder upon which the rubber-blanket plate is mounted. Alternatively, all of the functional layers can extend to the end of the carrier plate.

  • Method and apparatus for transferring a tape by spooling
    Publication number: 20060266869
    Abstract: A method and apparatus for transferring a tape by spooling is disclosed. A tape is transferred by spooling from a first, unwinding spool onto a second, winding spool, both spools being driven via a drive as a function of a predefined tape tension and/or a predefined tape setpoint speed at a setpoint rotational speed and/or with a setpoint torque. The respective setpoint rotational speed and/or the respective setpoint torque being determined as a function of a geometrical mean of the winding circumferences of the two spools.

  • Method and apparatus for controlling the web tension and the cut register of a web-fed rotary press
    Patent number: 7137338
    Abstract: To control the cut register of a web in a web-fed rotary press and to control the web tension decoupled from the control of the cut register, a specific item of image information or measuring marks of the printed web are registered by at least one sensor and the web tension is registered by at least one further sensor. The deviation of the position of the printed image with respect to its intended position, based on the location and time of the cut, is determined from the item of image information and is therefore available as actual values and supplied to a control device. The cut register error and the web tension can be influenced in a manner decoupled from each other.
