Abstract
A device for feeding envelopes from a hopper to an envelope processing station. Driving and driven rollers feed the envelopes one at a time from the hopper. The rollers define a nip through which the envelopes are fed. A unique 'U' shaped spring forces the driven roller to contact the driving roller causing the driven roller to oscillate when no envelopes are fed. The oscillation helps envelope feeding by pulling and separating the lead envelope from the stack.
