ABSTRACT:
Packaging apparatus for helically wrapping articles with a stretchable flexible film of wrapping material. A first conveyor (11) transports unwrapped articles towards a wrapping material applicator (13) and a second conveyor (12) transports helically wrapped articles. The first and second conveyors are spaced apart and the wrapping material applicator (13) is disposed between the first and second conveyors. The wrapping material is applied between the first and second conveyors to wrap an article disposed in space between the conveyors. The applicator has a rotary ring (14) supported in rotation by a fixed guide ring. Wrapping film reels are mounted on the rotary ring and unwound around tensioning rollers. Relative motion of the guide and rotary rings is converted into rotation of the tensioning rollers by a gear train so the wrapping material is stretched prior to application to the articles. The packaging apparatus may be used to wrap any material around any sort of article.
