A sheet feeder for handling envelopes and the like in which a flexible retard pad projects into the feeder discharge opening, the upper part of the pad being unsupported with the lower part supported in an inclined position so that on feeding movement of an envelope from the tray, the leading edge of the topmost envelope strikes the unsupported part of the pad to deflect the pad out of the way while the leading edges of other envelopes in the tray that are carried forward by feeding of the topmost envelope engage the supported part of the retard pad and are prevented by the pad from being fed.
