  • Vacuum sheet feeding apparatus including cylinder and upstanding nozzles
    Patent number: 5833228
    Abstract: A vacuum high-speed feeding apparatus equipped structure for moving suction nozzles attached to a cylindrical body towards sheet feeding rollers. The application of suction force is suspended upon detection that a drawn sheet has been caught and its conveyance has been stated by feeding rollers. This is done by detection of a leading edge of the sheet by a first sensor. The cylindrical body is restored to its home position when feeding of the sheet by a given distance is detected by a second sensor. The suction force is again applied when passage of the rear edge of the sheet through the feeding rollers is detected by the first sensor.
