Batch feeder for piece goods made of flat material

A batch feeder, comprising a feeder pit for stocking and gravity conveying of piece goods made of flat material in a downward conveying direction, the feeder pit comprising an upper opening for batch-based feeding of the piece goods, a lower opening for extraction of the piece goods, and at least two lateral pit delimitations comprising a first pit delimitation and a second pit delimitation located opposite to one another for guiding of the piece goods, each pit delimitation comprising an interior surface facing the feeding pit,

• wherein the interior surface of the first pit delimitation comprises carrying structures formed thereon for supporting the piece goods on one side, the carrying structures arranged on top of each other and configured to protrude into the feeder pit, and
• wherein the interior surface of the second pit delimitation is substantially smooth, having a roughness of less than 1 mm and formed for smooth guiding of the piece goods,
• wherein the carrying structures form retaining floors having a distance from one another in the conveying direction such that the piece goods can incline increasingly while moving on the second pit delimitation in the conveying direction until the piece goods slide off the carrying structures of one retaining floor onto the carrying structures of the retaining floor directly below, and
• wherein the first pit delimitation comprises at least two rails on which the carrying structures are formed.
