ABSTRACT:
A stacking apparatus has lower and upper continuous, rotating elastic cords 10, 11, between which delivered sheets 2 are conveyed to a pair of transport rollers 3. The rollers 20, 21 of the pair have wedge-shaped recesses 26, 27 with stop shoulders 28, 29, which are in alignment when the rollers are in their normal or rest position. The sheets strike these shoulders and stack up into a bundle 55, which is transported away in response to a discharge signal by the synchronous rotation of the rollers through an integral number of revolutions. The apparatus enables an efficient gathering of sheets into a precisely aligned bundle, which facilitates further processing.
