Abstract: A production-machine door assembly has an annular frame fixed on the production machine and defining an opening through which access to its workspace is possible. A plurality of door panels in a closed position are generally coplanar and substantially cover the opening with edges of the door panels immediately juxtaposed. Respective releasable hinges at the edges pivotally connect the door panels together and are releasable to allow separation of the door panels from one another. A guide structure serves for, when at least one of the hinges is released, folding the door panels together.

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.
