PROBLEM TO BE SOLVED: To provide a batch stacking apparatus which enables smooth feeding of corrugated cardboard sheets to a back stopper and alignment-stacking thereof while preventing the corrugated cardboard sheets from being bent. SOLUTION: The apparatus comprises an ejection conveyor 9 at the downstream of a carrier conveyor 8, a pressing feeder belt 13 with both ends lifted up which presses the corrugated cardboard sheet 3 like covering the ejection conveyor 9 and the carrier conveyor 8, a back stopper 14 to neatly align both ends of a batch of corrugated cardboard sheets 3, and a tension pulleys 50, 51 placed at both sides of the back stopper 14 to adjust the tension of the pressing feeder belt 13, the back stopper 14 and the tension pulleys 50 and 51 being placed in-line of the pressing feeder belt 13, wherein the back stopper 14, the tension pulleys 50 and 51 are formed movably back and forth in accordance with the length of the corrugated cardboard sheets 3. This enables smooth feeding to the back stopper 14, and batch stacked corrugated cardboard sheets can be neatly aligned with no violent rebound at the back stopper 14 and no bending of the corrugated cardboard sheets 3.
