  • Method for mounting a metering device
    Patent number: 5662043
    Abstract: A plurality of inking blade plates are positioned in abutting fashion between cooperating insertion and clamping strips to form an inking blade. A temperature differential is created between the blade plates and the strips which are then allowed to return to a common temperature. This creates a uniform spacing between each of the inking blade plates in the inking blade. The resulting inking blade is usable with an ink ductor roller in a rotary printing press.

  • Rubber blanket cylinder for offset printing
    Patent number: 5653169
    Abstract: A rubber blanket cylinder for offset printing utilizes a cylinder body that has magnetic strips to retain a rubber blanket packing comprised of a rubber blanket and a ferromagnetic rubber blanket support. A fastening strip is positioned on the circumference of the cylinder body and extends axially along the cylinder. The rubber blanket packing is prevented from wandering or shifting by the fastening strip. A free end of the fastening strip is covered by the rubber blanket which is thus fastened on the cylinder body in an essentially gap-free manner.

  • Holding device for a chamber doctor blade
    Patent number: 5642664
    Abstract: A holding device for a chamber doctor blade utilizes spaced holders which support the base body of the chamber doctor blade for sliding movement toward or away from a screen roller. This sliding movement is accomplished by spring forces exerted through a spring loaded pressure element and a pressure cam which oppose each other. The pressure cam can be shifted by an adjusting device through a spring biased tappet.

  • Chain sheet delivery system for a rotary printing press
    Patent number: 5640908
    Abstract: A method and apparatus that uses chain delivery system to deliver printed sheets to one of two sheet stacks is disclosed. The sheets are grasped by chain gripper systems and are transported along an upper chain strand. A transfer cylinder is positioned in the path of sheet travel between the two sheet stacks. Sheets destined for the second sheet stack are removed from the upper chain strand by the transfer cylinder and delivered to the second sheet stack by a lower chain strand.

  • Chamber doctor blade assembly
    Patent number: 5628250
    Abstract: A chamber doctor blade assembly includes axially spaced lateral cheeks that seal the ends of the ink reservoir. Each of these lateral cheeks has a sealing face that conforms to the curvature of the screen roller with which the chamber doctor blade is used. These sealing faces are provided with lubricant reservoirs. The lateral faces also have leading edges bent or flared out to form strippers which remove excess beads of ink from the screen roller.

  • Method and apparatus for damping a paper web
    Patent number: 5618584
    Abstract: Damping fluid is applied to a surface of a paper web and is caused to be transported into the web by a gas pressure gradient. The surface of the paper web bearing the damping fluid is subjected to a higher pressure over a large area. The gas pressure gradient can be changed or controlled to vary the rate of damping solution absorption into the paper web.

  • Web capturing device
    Patent number: 5615610
    Abstract: A web capturing device is provided with two cooperating web capture rollers which define a capture gap through which a web passes. The capture gap spacing is made as small as possible by the utilization of a web stabilizing assembly that eliminates fluttering and vibration in the web. This web stabilizer is formed by two generally parallel stabilizer plates that define a clearance space through which the web passes.

  • Device for measuring the bending of a cylinder
    Patent number: 5591921
    Abstract: Bending movement of a cylinder in a rotary printing press is measured by using a bending rod that is connected to the cylinder journal at one end and to a lateral register adjustment device at its other end. The bending rod is acted on by the bending forces applied to the cylinder and carries strain gauges that detect the bending of the bending rod. A double jointed coupling is used to connect the lateral register adjusting device to the cylinder journal. The bending rod is situated within this double jointed coupling.
