Embodiment Construction

[0016] refer to figure 1 , reference number 1 designates as a whole a packaging machine according to the invention.

[0017] This packaging machine 1 allows packaging of products starting from a strip 3 of wound material. Specifically, this tape 3 is wound on a roll 2 . In the case of food wrapping, the wrapping material may be a film in polymer form. The wrapping material may also include an inner or outer cover suitable for the product to be packaged. Additionally, the wrapping material is heat sealable.

[0018] The roll 2 is unrolled to provide said coiled material 3 . The belt 3 is then advanced along the advancing direction "A".

[0019] The packaging machine 1 comprises a cartridge-forming device 5 . This forming device comprises drive means (not shown) for the cylinder 5, which cause the cylinder 5 to move in said advancing direction "A".

[0020] The forming device also comprises a tubular forming member 4 of known type, operatively located downstream of the ro...

Abstract

A packaging machine (1) comprises a device for the formation of a tube (5) of wrap material into which a succession of products (6) can be inserted; a sealing device (7) being active on said tube (5) to make a succession of seals (23) transverse to the direction of advancement "A" of tube (5) and to define a corresponding succession of pockets (11) for holding the products (6); an air-removing device (13) being active on each pocket (11) in correspondence of a respective aperture (25) to produce a vacuum inside each pocket (11); and an additional sealing device (22) operatively located at least in correspondence of the air-removing device (13) for isolating said aperture (25) and hermetically sealing the pocket (11).

Description

technical field [0001] The invention relates to a packaging machine and a method for packaging articles. In particular, the machine and method according to the invention are applied to the packaging of foodstuffs such as bakery products, cold pork and the like. In the following description, reference is made to such an application without prejudice to the generalization. Background technique [0002] Packaging machines are known for packaging items starting from a wound strip of plastics material. [0003] The strip unwound from the roll is moved in the feed direction towards the cartridge-form, which is plastics material and is operatively located downstream of the roll. Specifically, a tape is wound around this profile to form the cartridge by overlapping the two side edges of the tape. Furthermore, the barrel is completed by longitudinally welding said side edges to each other by means of first welding means provided corresponding to the profile. [0004] Packaging ma...
