In the device and the method for transferring blister packs, two blister packs are first transferred from a stamping station to an intermediate place element and then from the intermediate place element to a single-file conveying means. The two blister packs are placed on the intermediate place element next to each other in a row on either side of a longitudinal center plane of the device. During the transfer from the intermediate storage element to the conveying means, both blister packs are picked from above from their intermediate place positions and also placed from above in the common final place position. When in the final place position, each blister pack has the same side facing up as in the corresponding intermediate place position but now with a rotation of 180&#xb0; around its center. In addition, the blister packs acquire a lateral offset from the longitudinal center plane during the transfer.

Device and method for transferring blister packs

An apparatus for sealing a cover film to a blister film having blisters holding respective small objects has a feed roll rotatable about an axis and formed with an array of radially outwardly open recesses arrayed like the blisters of the blister film. The blister film passes over the feed roll with the blisters in the recesses. A sealing roll is rotatable about an axis generally parallel to the feed-roll axis and presses the cover foil down against the blister foil on the feed roll. The feed roll is rotated to pull the films in a travel direction between the rolls so that the cover film is sealed to the blister film between the blisters thereof. A sensor detects movement of the sealing roll transversely of the feed-roll axis. A controller generates an output when the detected movement exceeds a threshold.
