Abstract: A device and a method detect an edge of a recording material, in particular a printing plate, in an exposer for recording printing originals. An exposer has an exposure drum for holding the printing plate, and an exposure head, which is moved axially along the exposure drum and focuses exposure beams onto the printing plate. The position of the edge of the printing plate is determined by a sensing device. To this end, a sensing finger is pivoted into a groove in the surface of the exposure drum and a signal is generated by a sensor when the sensing finger moves when it touches the edge of the recording material. The sensor used is preferably a microswitch. The axial position of the edge of the printing plate is determined by counting the cycles of the feed drive that moves the sensing device.

Abstract: The skew of a sheet of print media is precisely controlled by intentionally inducing print media deformation, so that cooperative mechanical and gravitational forces may be used to align the leading edge of the sheet. The sheet is driven into a nip region of deskew rollers in a manner that causes the print media to deform, lifting a movable member in a direction substantially perpendicular to the feedpath into the nip region. The movable member applies a return force that is generally equal along a widthwise surface region of the print media. As a result, there is a reduced likelihood that the print media will be skewed relative to the nip region. In some applications, the return force is adjustable.

Abstract: A sheet registration system, especially for printers, with a lower cost and lower mass system for sheets deskewing, and optionally also compatibly providing transverse registration repositioning of the sheets. Mechanisms are disclosed which need only one main drive motor to drive both of the two spaced apart sheet feeding nips, together with a much lower power, and lower cost, deskewing differential drive system for providing the relative differential angular movement of the two spaced sheet feeding nips to achieve the desired amount of sheet deskewing movement, without interrupting the forward feeding movement of the sheet.

Abstract: When a film is rewound, light is applied from light-emitting units to the film, and light that has passed through the film is detected by light-detecting units to detect a plurality of inclined defects in the film based on a change in the intensity of the light transmitted through the film. Slits oriented in the direction of the inclined defects are disposed in front of the light-emitting units and the light-detecting units. Detected signals outputted from the light-detecting units are transmitted to a processing device and processed thereby. The processing device processes the signals by approximating a maximum value array of extremal values of the signals in respective reference lengths of the film, with two functions in zones, and identifying a boundary between the zones as a position where a defect disappears.

Abstract: A sheet feeder is provided comprising at least two drives that drive a sheet of material along a paper path and at least two sensors that detect a lateral side of the sheet of material. A controller is connected to the two sensors and at least one of the drives. The controller varies the drive velocity of at least one of the drives to shift the lateral position of the sheet of material in a predetermined direction until one of the sensors detects the lateral side and then varies the velocity difference of the two drives to eliminate the skew of the sheet.

Abstract: A method and device for aligning stacked or piled sheets in a feeder of a sheet-processing machine, wherein a sheet to be separated is pivotable about a vertical axis extending at least approximately orthogonally to a transport direction of the sheet, as viewed in the transport direction thereof, in order to correct a skewed position of a leading edge thereof relative to at least one front lay. The method further includes determining, relative to the front lay, a skewed position of sheets oncoming at the front lay or resting at the top of the sheet pile, and displacing, transversely or approximately transversely to the transport direction, either the sheet pile, before the sheet is lifted therefrom, or the sheet lifted off the sheet pile, depending upon the determined skewed position, over a displacement distance that is of such length that, after the skewed-position correction, there is a defined spaced distance between a side edge of the sheet and at least one side lay.

Abstract: An articulated flag body member permitting bidirectional passage of an object. The articulated flag body member has a flag body pivotably connected to a flag foot. As rotation of the flag foot occurs in one direction, the flag body rotates by engagement of a recess of the flag foot with a stop member extending along a projecting leg of the flag body. As the flag body rotates, a notch at the upper portion of the flag body changes positions such that light, or other signals, may no longer pass through the notch. Thus, positional indication of an object detected by rotation of the flag body. As rotation of the flag foot occurs in an opposite direction, an object may be extricated or removed.

Abstract: The present invention relates to a system for providing diagnostic information relating to the performance of an inserter system having a roller arrangement for conveying a document in a linear direction and first and second sensors located in close proximity to the roller arrangement. Each of the sensors are operable to detect at least the presence of a leading edge of a document conveying in close proximity to each sensor. The control system of the inserter determines the time it takes for a leading edge of a document to convey from said first sensor to said second sensor and compares that time to a prescribed threshold time and provides diagnostic information based upon the measured times values.
