  • Patent number: 6240843
    Abstract: A sheet transport system for a rotary printing press, including a sheet transport device having a sheet holder, and a first and a second propulsive drive element for propulsively driving the sheet transport device guidingly in a first and a second guide rail, respectively, the second guide rail extending substantially parallel to the first guide rail, the first and the second propulsive drive elements forming rotors of an electric linear drive, the first and the second guide rails having a plurality of drive stations disposed thereon and forming a stator of the linear drive, and a control device assigned to the drive stations for controlling and regulating movement of the first and the second propulsive drive elements, each of the first and second propulsive drive elements being a structure formed of magnetizable material, at least part of which is movable relative to another part thereof, and the drive stations being spaced from one another, at least in some sections of the sheet transport device, a distance

  • Patent number: 5429051
    Abstract: Printing-unit assembly of a web-fed printing press, the printing-unit assembly having a smear-preventing device and being assembled of at least two satellite printing unit sub-assemblies, respectively, including a satellite cylinder, one of the satellite printing unit sub-assemblies being actuatable for printing on one side of web stock, and the other of the satellite printing unit sub-assemblies being actuatable for printing thereafter on the other side of the web stock, the smear-preventing device being associated with the satellite cylinder of the other satellite printing unit assembly for preventing smearing of printing ink, and includes a device for cooling an outer cylindrical surface of the satellite cylinder of the other satellite printing unit sub-assembly to a temperature below the dew point; and method of cooling.

  • Patent number: 4964337
    Abstract: An inker and form roller unit for a printing press includes a continuously rotating fountain roller for carrying ink from a reservoir. A combi-roller is in constant contact with a distribution roller to deliver ink to rollers of the printing press. The combi-roller and distribution roller are supported by a swivel lever that can pivot about the rotational axis of the distribution roller. The swivel lever carries a cam roller for contact with a control body having two or more sections, one of which is for continuous film inking and the other section for intermittent inking. The combi-roller is positioned relative to the fountain roller by the control body so as to form either a continuous fluid transfer gap or an intermittent fluid transfer gap.

  • Patent number: 3995553
    Abstract: A plurality of drive elements, such as electric motors supplied with sprockets, are located along a threading path for the paper web of a rotary printing press; a threading element, such as a sprocket chain of a finite length somewhat longer than the maximum space between drive elements is moved along the path, for example, in a guide channel, the threading element cooperating with switches located adjacent the drive elements to energize the drive element adjacent a leading edge of the threading element, and move the threading element along to the next threading element, the trailing end turning the switch OFF since drive power will be supplied by the next drive element along the path. This sprocket chain carries a gripper with which the leading edge of the paper web to be threaded into the printing press can be gripped.
