A discharge of paper or other leaves from the top (S) of a stack is by a rotating feed-roller (17;41) mounted on a carrier (7,11;35-39) that moves progressively along the stack in maintaining the roller (17;41) engaged with the top leaf. The carrier (7,11;35-39), which has a slot-mouth (8;52) through which the leaves are discharged successively by the roller (17;41), is guided in its downward movement by side-wall slots (12;40) of a casing (2;32) holding the stack, and has counter-balancing weights (23;50) attached for adjustment of the pressure of the roller (17;41) on the stack. In one form, the carrier is mounted on a plate which carries a motor for belt-drive to the roller, and which has sliding pivotal movement in the casing to enable the carrier to follow the guide-slots. Alternatively, the motor is located within the roller and ears of brackets on the carrier are located in the guide-slots to hold the carrier from tipping.
