Abstract
The present disclosure relates to a sheet feeding method and apparatus by which sheets of material can be fed, one at a time, into a processing or finishing machine. The present disclosure includes a continuously moving feed means that is driven and moves continuously at line speed. The continuously moving feed means are provided with vacuum means to pull the sheet into engagement with the feed means. A feed plate is provided for movement between a lowered, feed position in which the feed plate is lowered to a position below the feed means and a raised, no feed position in which the feed plate is raised to a position just above the feed means to prevent a sheet from being fed. In one embodiment, the movement of the feed plate is provided and controlled via a rotating, profiled eccentric which is driven by a servo electric motor.
