ABSTRACT:
The invention relates to an apparatus for wrapping and closing a blank (1) of wrapping material around an article to be packaged. The wrapping blank consists of a rectangular piece of protective cardboard (3, 4), serving as an outer jacket for the package, and of a wrapper element (2) fastened to the other surface of said protective cardboard and wrappable around an article. The side edges of a package are closable by folding both ends (3, 4) of protective cardboard around the side edges of an article. Folding the ends of a protective cardboard manually strains the wrists of a packing person which is why this working step is automated by means of an apparatus comprising a mechanism for folding the ends (3, 4) of a protective cardboard, a conveyor track (5, 13) and pusher elements (32) that can be reciprocally driven on either side of the center axis of said conveyor track, and press elements (22) therebelow for pressing the side edges of a package while said pusher elements (32) travel along the top surface of a package.
