ABSTRACT:
Each sheet is picked from a stack of sheets with the time of it being picked being determined in accordance with the time of the prior pick. The sum of the times to advance a sheet its length and a desired gap between adjacent sheets is equal to a pick delay time and an expected feed time. If the measured feed time of the prior sheet exceeds a maximum feed time, the pick delay is the same as for the prior sheet. If the measured feed time of the prior sheet does not exceed the maximum feed time and the measured feed time of the prior sheet was less than the expected feed time, the pick delay is greater than the pick delay of the prior sheet. If the measured feed time of the prior sheet does not exceed the maximum feed time and the measured feed time of the prior sheet was not less than the expected feed time, the pick delay is less than the pick delay for the prior sheet.
