ABSTRACT:
Envelopes are fed in a mutually overlapping state one by one toward a stopper provided at the front side of a transfer conveyor. Upon abutment with the stopper the envelopes pile up so as to be temporarily stored. An envelope feeder device is provided so as to enable a large number of envelopes to pile up. The envelope feeder device includes a body which is adjustably supported from a support shaft above the transfer conveyor, so as to position the feeder device according to the size of the envelopes. A pair of first rollers are mounted to both sides of the body and positioned so as to roll upon the upper surface of the transfer conveyor. Each first roller includes a rotary member mounted eccentrically on its side. A bifurcated feed member engages with the eccentric rotatable members so as to reciprocate horizontally as by the rotational movement of the first rollers, whereby assisting in the piling up of the envelopes as by a pair of claws located at the free ends of the bifurcated portions. Also, a bifurcated support member with a second pair of rollers located at the free ends thereof is fixed pivotally to the body and provided with a spring so as to constantly urge the second rollers toward the upper surface of the transfer conveyor.
