ABSTRACT:
A method for controlling the feeding of sheet material from a sheet feeding device, in which the sheets are stored in a stack and are fed seriatim by a feeding means to a staged position, in which the sheet is partially ejected from the feeding device, and in which the sheet must reach the staged position within total predetermined period of time from the moment that the feeding means is activated. The method comprises the steps of feeding the sheet from a stack to the staged position at a predetermined rate of speed and ascertaining whether the sheet reaches the staged position within intervals of time between each successively higher rate of speed. The operation of the feeding means is terminated when the sheet reaches the staged position within the total predetermined period of time. Further operation of the feeding means is deactivated if the total predetermined period of time expires before the sheet reaches the staged position, deactivation continues until the cause of the failure of the sheet to reach the staged position is ascertained and corrective action is taken.
