  • Automatic release timing control system
    Patent number: 4788908
    Abstract: An automatic release timing control system for use with a press and a cooperating feeder for feeding a web of sheet material wherein a sheet release timing and a sheet grip timing of a release mechanism in the feeder are corrected in response to the varying revolution of the press and the response time of the release mechanism, so that, even when the working speed of the press is high, the sheet releasing operation and the sheet gripping operation of the release mechanism can follow up the working speed of the press.
