Abstract: An apparatus for stacking flat articles on-edge has a helical drive assembly with spaced-apart helical screws. The helical screws receive and hold the articles on-edge therebetween, and eject the articles towards a stack holding unit. The stack holding unit is configured to hold a stack of articles on-edge separately from the helical screws. The apparatus includes a conveyor that supports the lower edges of the articles during their transport to the stack holding unit. The stack holding unit has an article entry opening with a height that is smaller than a height of the articles to be stacked during operation, and the height of the article entry opening is preferably adjustable.

Abstract: An inserting apparatus for placing a product in an envelope is provided with a discharge path. The discharge path is provided with a skewed roller conveyer which comprises a plurality of rollers arranged at an angle relative to the discharge conveying direction, to align the envelopes along a stop extending in the conveying direction of the roller conveyer. The discharge path is provided with at least one pressing device extending above the roller conveyor to press envelopes towards the roller conveyor, the pressing device comprising at least one array of vertically moveable, rotatable balls. The roller conveyor is provided with at least one endless transport belt for the envelopes, extending opposite the at least one pressing device, the endless belt extending substantially transversally with respect to the rollers.
