Abstract
An improved apparatus for reverse buckle feeding of sheets seriatim from a sheet supply stack. The sheet feeding apparatus includes a feed roller, mounted for rotation about a longitudinal axis. The feed roller has a frictional sheet feeding peripheral surface in juxtaposition with one of the sheets of such stack. A second roller is mounted for rotation within the feed roller about a second axis which is parallel to the longitudinal axis of the feed roller. The second roller has a frictional sheet engaging peripheral surface, a portion of which extends through an opening in the peripheral surface of the feed roller radially beyond such surface. The second roller acts to urge the engaged sheet in the direction opposite to the feed direction. The feed roller and the second roller are simultaneously rotated in opposite directions about their respective axes, whereby the sheet engaging surface and the sheet feeding surface sequentially engage each sheet of the stack to first separate (buckle) and then feed the same from the stack. The apparatus may further include means to facilitate unimpeded movement of a fed sheet, relative to the sheet feeding surface, once the fed sheet is moving under the influence of a downstream transport. Such means also acts to prevent premature feeding of subsequent sheets.
