  • Patent number: 5609428
    Abstract: A sheet carrying apparatus reduces skew of a sheet during carriage, and realizes high-quality print. A position detecting sensor detects a position in a direction perpendicular to a sheet carrying direction of the sheet carried by a sheet carrying roller. A skew angle of the sheet is calculated depending upon a deviation of the detected position from a predetermined reference position. Load rollers are on the right and left sides with respect to a sheet center line in the sheet carrying direction, and are respectively opposed to following rollers through the sheet so as to bring the sheet into pressure contact. A torque limiter to apply a braking force to the load roller, and the load roller are coupled or released by electromagnetic clutches. Thereby, the carrying forces can independently be controlled on the right and left sides of the sheet depending upon the skew angle.

  • Patent number: 5555805
    Abstract: The printing unit has two cooperating cylinders (1, 4) which form the printing nip and which have printing saddles (2, 5) separated by cylinder pits (3, 6). The paper web (7) passing through the printing nip is transported in the pilgrim-step mode, in order to print formats adjoining one another. The two cylinders (1, 4) are angularly adjustable relative to one another, in respect of the position of their printing saddles (2, 5) cooperating in the printing nip, in a manner offset by the amount of a circumferential distance which is approximately equal to the difference between the circumferential length (S) of a printing saddle and the circumferential length (B) of a printing image. The impression zone is therefore only approximately as large as the printing image, and the impression-free zone available for retracting the paper web is correspondingly enlarged.

  • Patent number: 5405205
    Abstract: The invention disclosed herein provides a method and apparatus for counteracting the effects of a localized drag on a sheet medium as it is being moved by a drive system, for example, in a printer or plotter to prevent misregistration of the sheet medium with the X-axis drive system as the sheet medium is moved past the print or plot head which creates a drag thereon. The sheet medium is stiffened in the region thereof which is contacted by the print or plot head by bending the sheet medium in a direction normal to the direction of movement of the sheet medium. The bend may be provided by a curved guide located between the print or plot head and the X-axis drive system. Friction is reduced between the sheet medium and the curved guide by mounting the curved guide, e.g., one or more rollers, to rotate freely under the action of the sheet medium moving thereover, or by pneumatically supporting the sheet medium above the curved guide as the sheet medium is moved thereover.

  • Patent number: 5386772
    Abstract: 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.

  • Patent number: 5372290
    Abstract: An apparatus for removing a running torn web of material is disclosed having two rollers parallel to each another disposed on a same side of the running web of material, so that the axes of the two rollers are orientated horizontal to each other and perpendicular to the direction of movement of the running web of material. The apparatus is provided with a manifold disposed on the side of the web opposite to the two rollers and provided with blowing nozzles placed in line with an inlet region formed by the two rollers in rotation. The manifold is supplied with compressed air when a detection system has detected the tearing of the web. The compressed air exits the blowing nozzles exerting a blowing force on the torn web of material causing it to engage between the two parallel rollers in rotation.

  • Patent number: 5320039
    Abstract: A web engagement system for an off-reel printing press comprising a guide piece, a guide channel and drive stations for the displacement of the guide piece. The guide channel accommodates and guides the guide piece and is located on the frame of the press between the drive stations. The guide piece is slightly longer than the distance separating the various drive stations. The advance of the guide piece is caused as a result of the displacement of a slide equipped with wedging rollers which alternately grip and release the guide piece. A pair of wedging rollers prevents the return movement of the guide piece. The invention is used for introducing paper webs unwinding continuously in an off-reel printing press.
