Patent number: 6766737Abstract: The circumferential register of a web passing through printing units of a web-fed rotary press is accomplished by determining an actual value of the tension in the web. An angular position or an angular velocity of a cylinder of a first print unit, with respect to a cylinder of a second print unit, is varied based on this determined tension. This corrects any register offset without the need to control web tension and without the use of an optical recognition system. The value of the needed change for the cylinder angular position or velocity is determined as a function of the measured tension of the web.Type: GrantFiled: May 27, 2003Date of Patent: July 27, 2004Assignee: Koenig & Bauer AktiengesellschaftInventors: Erhard Herbert Glöckner, Reinhard Georg Gross

Patent number: 5392976Abstract: A master tape movable in a closed loop including a pinch roller transfers a mirror image to a slave tape movable in a closed loop including a capstan. A thermomagnetic layer on the slave tape has a Curie temperature above which magnetic information is destroyed and below which magnetic information can be recorded on such layer. The thermomagnetic layer is heated above the Curie temperature, thereby becoming lengthened by thermal expansion just before the slave tape reaches the capstan. A downstream portion of a peripheral surface, preferably defining a cylindrical segment, on a first guide receives a pressurized fluid for sensing the tape tension in accordance with the tape width, distance from the cylinder axis and fluid pressure. An upstream portion of the guide peripheral surface receives a vacuum adjustable to regulate tape tension in response to variations in the pressurized fluid pressure.Type: GrantFiled: May 19, 1992Date of Patent: February 28, 1995Assignee: Hightree Media CorporationInventors: Alfred M.

Patent number: 5386772Abstract: A high speed media management device has tractor means for moving a web through the device past a plurality of work stations at each of which the web may be treated. Relatively high web tension is maintained throughout its travel path. Counting means near the beginning of the web path generate a count signal with the passage of each increment of web. The accumulated count signals are compared to numbers stored in a plurality of registers, each register associated with a work station and each containing a count representative of web travel distance relative to the work station. The first register count corresponds to the distance required to accelerate the web from a stop. The remaining registers store that count and a separate count representing the distance between the first station and the corresponding station. When the counter contents equals the count in a register, an actuating signal initiates a treatment activity at the associated work station.Type: GrantFiled: June 15, 1993Date of Patent: February 7, 1995Assignee: Datametrics CorporationInventors: Charles V.

Patent number: 4542893Abstract: 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.Type: GrantFiled: November 14, 1984Date of Patent: September 24, 1985Assignee: Bell & Howell CompanyInventors: Marvin B.
