A method for generating decks of sheet elements (18) comprises the steps of positioning a set of numerous sheet elements (18) onto a transport surface of a transport device (30) to partly overlap in transport direction (T). The set of overlapping sheet elements (18) is moved against a stop member (44). The stop member (44) is moved in the transport direction (T) with a lower velocity than a velocity of the transport surface. By maintaining displacement of sheet elements (18) which are not yet contacting stop member (44) all sheet elements are shifted towards stop member (44) to define a deck. The method is carried out by a corresponding device.

A blister package stacker having a nest inlet for reception of blister packages from a conveyor, a nest assembly for holding one of the blister packages, and a blister package collection tower for storing a stack of the blister packages. The nest assembly is configured to insert one blister package at a time upward into a bottom of the blister package collection tower. The blister package stacker may have a push arm which pushes the stack of the blister packages from the collection tower into storage tubes.

A blister collation system includes a blister packager with a blister seal station which seals a blister package with a medicament inside and a blister package stacker connected to the blister packager via a conveyor which moves individual blister packages. The blister package stacker has a nest inlet for reception of the blister packages from the conveyor, a nest assembly for holding one of the blister packages, and a first blister package collection tower for storing a stack of the blister packages. The nest assembly is configured to insert one blister package at a time upward into a bottom of the first collection tower. The stacker further has a tower gate holding the inserted blister packages and a mechanism for pushing the stack of the blister packages from the first collection tower into a storage container.
