Machine for packing an object in a plastic sleeve - compresses sleeve into bellows form before passing object through

摘要

The machine consists of a mechanism for pre-arranging the plastic sleeve destined to enclose the object. The sleeve is fed into a magazine and folded bellows fashion until there is sufficient plastic sheet in the magazine to cover the entire object. The plastic is stretched sideways to ensure that the object will enter the sleeve. When it is placed in position to be wrapped, the object moves away from the magazine, pulling the plastic folded sheet with it. When the item is wrapped, the plastic sheet is cut and welded so as to form a seal at each end.
