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.
Apparatus for wrapping a commodity comprising means for supplying a pair of opposed lengths of air-impermeable wrapping material each having a pair of opposed free lateral edges, means for placing said pair of lengths of wrapping material in registry, said lengths of wrapping material being secured together along a leading edge to form an open-sided envelope having a closed leading portion, means for advancing said commodity along a fixed path into engagement with said wrapping material between said pair of sheets of wrapping material, means for sealing said opposed free lateral edges of said pair of sheets of wrapping material together to form an envelope having closed sides and a closed leading portion with said commodity therein, means for severing said opposed lengths of wrapping material across the width thereof to form a container length, means for sealing said open trailing end to form a wrapped commodity enclosed in a wrapper.
A method of wrapping a commodity comprising the steps of supplying a commodity to be wrapped, supplying a pair of opposed lengths of wrapping material each having a pair of opposed free lateral edges, placing said opposed pair of lengths of wrapping material in registry, said lengths of wrapping material having a closed leading end, advancing said commodity along a fixed path into engagement with the wrapping material between the opposed sheets of wrapping material, sealing the free lateral edges of the sheets of wrapping material together to form an envelope having closed sides and a closed leading portion with said commodity therein, severing the opposed lengths of wrapping material across the width thereof to form a container length, and sealing the open trailing end to form a wrapped commodity enclosed in a wrapper.
