A sheet feeding device is particularly useful in feeding sheets from a stack in apparatus in which a trailing portion of the sheet is returned toward the stack as the sheet moves through a reciprocating path. Corner nails used to help prevent double feeds in the sheet feeding device are attached to a guide means positioned to guide the trailing portion above the stack. The nails and guide means float vertically with respect to the top of the stack, preventing interference between the leading edge of the sheet and the guide means and between the trailing edge of the sheet and the stack.
