Abstract
A sheet-feed mechanism for feeding paper or the like from a stack of paper sheets in a tray in which the sheets have a soft or pressure-sensitive coating, includes a sheet-engaging apparatus which distributes the load over a substantial area of the sheet, in order to control the pressure on the sheet. Simultaneously, the apparatus is moved in a direction to cause buckling of the exposed or first sheet, for separation from the stack and subsequent removal. Two embodiments are disclosed. One embodiment employs a pair of feed wheels and another embodiment employs a sheet-engaging flat pad. The wide feed wheels or the pad are caused to be moved, following engagement with the exposed sheet, in a direction generally parallel to the plane of the sheet, for causing the separation of the sheet. In this manner, the loading imprint is not confined to a specific area, with respect to the underlying sheets, thereby preventing pressure marking or scuffing of the sheet immediately under the first sheet removed by the feed mechanism.
