METHOD OF PRODUCING CONDITIONED FIBROUS MATERIALS WITH A REDUCED TENDENCY TO WRINKLE DUE TO VACUUM PACKAGING AND IF DESIRED VACUUM PACKAGING THE SO CONDITIONED MATERIALS

摘要

There is provided an apparatus for wrapping commodities, which may be compressible, and a corresponding method, in which a commodity is conveyed along a fixed path, a pair of opposed lengths of wrapping material are fed in an opposed relationship and in registry, the commodity is inserted between the opposed lengths of the wrapping material which have a leading end which has been sealed to form an open-sided and open-trailing end envelope, the lateral sides of the wrapping material are then sealed, and thereafter, a bag length is severed from the pair of lengths of wrapping material and sealed. Preferably, the commodity is fed under compression in between the opposed lengths of wrapping material, maintained under compression while the wrapping material is side-sealed and is vacuum-packaged while also under compression.
