  • Method of regulating a web tension
    Patent number: 6211968
    Abstract: A process for adjusting a web tension in a web-fed rotary printing machine addresses the problems of processing variables which are not precisely quatifiable, while minimizing the influence of the press operator. This is achieved by adjusting the web tension using rules of fuzzy logic.

  • Process and device for the qualitative assessment of processed sheets
    Patent number: 6192140
    Abstract: The quality of processed or printed sheets is assessed while the sheets are supported on the periphery of a drum. The surface of each drum is provided with sheet leading and trailing end gripper systems which are circumferentially, and axially shiftable with respect to each other. Each sheet to be inspected is stretched tightly on the periphery of its supporting drum before the quality of the printing or other processing done to the sheet is assessed.

  • Sheet processing machine with a chain conveyor
    Patent number: 6131496
    Abstract: A sheet processing machine utilizes chain conveyors, each of which are provided with a plurality of chain gripper devices, to convey sheets. As each sheet is conveyed, it is cut by a transverse cutting device and is inspected. Each cut and inspected sheet may then be separated into several partial sheets which are then conveyed independently of each other to selectable stacks in a sheet delivery system.

  • Apparatus for moving point needles
    Patent number: 6128988
    Abstract: Point needles in a conveying cylinder of a rotary press are caused to follow a curve course which securely fastens a web to the cylinder while eliminating transport damage to the printed products as well as reducing paper waste. The needle tips of the point needles are moved along their path by the superimpositioning of two pivot movements, one of which is accomplished by a point holder arm and the second of which is accomplished by a rocker. The two cooperate to form a level four member swivel joint.

  • Apparatus for moving point needles
    Patent number: 6125728
    Abstract: Point needles in a collecting cylinder are driven in a two stage extension process to initially needle or pierce the leading edge of a product web being cut. Once the cut has been made, the needle tips are moved further radially outwardly from the cylinder to secure the cut edge. As the signatures are transferred to a folding cylinder, the needle points are retracted along a single stage retraction curve which is different from the path traveled during the two stage extension process.

  • Conveying system
    Patent number: 6070534
    Abstract: A conveying system for transporting loads utilizes a transport cart that is supported by rollers. The transport cart is supported by the rollers adjacent several serially arranged revolving drives that each have a plurality of spaced recesses. At least one pusher is carried by the cart and engages a recess in the drive. The cart can be halted, if its path is blocked, by disengagement of the pusher from the recess in the drive.

  • Method and device for keeping clean ends of spray damping mechanism nozzles on rotary printing press
    Patent number: 6067908
    Abstract: Deposits are removed from the end of a spray dampening nozzle which is used to spray pressurized fluid that is delivered to the nozzle end. This fluid is activated by ultrasound before it exits the nozzle end. The activation of the fluid can be accomplished upstream of, or at the nozzle end. An ultrasound vibrator is used to activate the fluid and is either directly or indirectly connected to the fluid by a vibration transmitter.

  • Sheet-fed offset rotary press
    Patent number: 6062136
    Abstract: A sheet-fed rotary offset printing machine accomplishes multi-color printing. A central impression cylinder carries sheets to be printed as they pass by at least two serially located blanket cylinders. These blanket cylinders are provided with ink images from cooperating plate cylinders. A sheet is gripped only once by grippers of the impression cylinder and is held in this single gripping operation during printing. At least one short inking unit is associated with each printing cylinder.

  • Folded product
    Patent number: 6053684
    Abstract: A method and a device for the production of folded products utilizes a row of folding jaws and a row of counter folding jaws. A signature to be cross-folded is inserted between the jaws by a folding blade. The folding jaws and counter folding jaws form a line of embossing on the folded signatures adjacent the transverse fold line. The resultant folded item has an increased moment of resistance in the direction of transport.

  • Method for detecting the position of a web supply roll and for positioning the roll
    Patent number: 6007017
    Abstract: In a method for detecting the position of a web supply roll, the actual lateral positions of the two lateral faces of the web roll are detected and are compared with reference values. The differences between the actual and the reference values are used to shift the web supply roll laterally until the actual values are the same as the reference values.

  • Cutting device
    Patent number: 5983764
    Abstract: A cutting device for transversely cutting a traveling web into signatures is usable to cut signatures into equal or unequal lengths and to accomplish proper register of the cuts. This is accomplished by supporting at least one cutter blade in a cutting cylinder so that the blade can be shifted circumferentially, and by supporting the cutting cylinder so that it can be phase-shifted.

  • Paddle wheel for laying out folded products
    Patent number: 5975525
    Abstract: A paddle wheel is used to deliver folded products to a conveyor belt in a shingled fashion. The paddle wheel has a plurality of pockets which are formed by circumferentially spaced curved paddles. The thickness or width of each product receiving product is adjustable by providing a guide strip in each pocket. The end of the guide strip adjacent the bottom of each pocket can be shifted radially with respect to the axis of rotation of each paddle wheel by actuation of a drive assembly.
