Abstract

A blister-pack package is made by forming a strip with a plurality of fields of upwardly open pockets and filling the pockets with respective objects while leaving at least one pocket empty and then scanning the fields and determining an address of the empty pocket in the respective field. A refilling head is then loaded at a stationary location with at least one of the objects. The loaded refilling head is then positioned above the empty pocket in accordance with the determined address, and the object is dropped from the loaded and positioned head into the empty pocket.
