Abstract
A sheet feeder having an auxiliary pile supporting device for non-stop operation includes a removable auxiliary pile support of given thickness on which an auxiliary pile of sheets are supported above a liftable main sheet pile with which it is joinable. The sheet feeder bar stops disposed in a sheet feeding path of the auxiliary sheet pile and engageable by a leading region of the auxiliary sheet pile as viewed in sheet feeding direction. The sheet feeder further includes a holding device disposed substantially in a plane extending over the width of the sheets and movable under the leading region of the auxiliary pile, when the auxiliary pile support is removed, for permitting leading edges of the sheets in the auxiliary pile to be lowered a distance equal to less than the thickness of the removed auxiliary pile.
