ABSTRACT:
A feed roll has a plurality of equiangularly spaced flat faces thereon for engaging a restraint roll to form a nip therebetween through which the lowermost envelope in a stack of envelopes is fed. A spring continuously urges the restraint roll into engagement with the feed roll. In one embodiment, curved portions connect the flat faces to each other. In another embodiment, the adjacent flat faces intersect each other to form comers on the periphery of the feed roll.
