In a feeding apparatus for material sheets, package blanks (B) are stored stacked in layers in a hopper (2) that opens downward, for example. A plurality of stopper guides (20) are arranged at intervals in the longitudinal direction of the package blanks (B) at the outlet of the hopper (2). Restrainer lugs (24) are located continuous with the guide surfaces (22) of the stopper guides (20). The package blanks (B) are supported in layers on the stopper guides (20), and the lowest one is supported directly on the guide surfaces (22). Since guide surfaces are inclined in the direction of delivery of the package blanks (B), the lowest one of the package blanks (B) deflects to the maximum degree, and a gap is formed between the lowest package blank and the overlying package blank (B). Further, the package blank (B) can be delivered as it gets over the restrainer lugs (24) by elastic deformation.
