Abstract
A packaging machine is described for forming, filling and sealing bags with a product. The machine forms a film into an elongate, side-sealed tube as it travels in a first direction, and severs the elongate tube into individual, open-ended, bag-length elements. These are then transported in a second direction transverse to the first direction, and a bottom seal formed on them to convert them into open-topped bags. A carousel is arranged to receive the open-topped bags. Product is introduced into each of the open-topped bags, and a top seal formed on each of them to convert them into filled, sealed bags, as the bags travel round the carousel.

A packaging machine for continuous operation for forming, filling and sealing bags of a product comprising:
- means for forming a film into an elongate, side-sealed tube as it travels in a first direction, means for severing the elongate tube into individual, open-ended, bag-length elements, belt means for transporting the said elements in a second direction transverse to the first direction, means for forming a bottom seal on said elements to convert them into open-topped bags, a carousel in-line with said transporting means that are continuously moving for receiving the open-topped bags as the open-topped bags travel tangentially to said carousel at a speed substantially matching that of said carousel, so that the transport means transport said elements continuously onto said continuously moving carousel, and means for introducing product into each of the open-topped bags and for forming a top seal on each of the bags to convert them into filled, sealed bags, as the bags are moved round the carousel.
A packaging machine for forming, filling and sealing bags with a product comprising:
- means for forming a film into an elongate, side-sealed tube as it travels in a first direction, means for severing the elongate tube into individual, open-ended bag-length elements, means for forming a bottom seal on said elements to convert them into open-topped bags, a carousel arranged to receive the open-topped bags, transporting means for continuously transporting said elements in a second direction transverse to said first direction and tangential to said carousel to introduce said elements tangentially to said carousel at a speed substantially matching that of said carousel whereby the transporting means transports said elements continuously onto said continuously moving carousel, and means for introducing product into each of the open-topped bags and for forming a top seal on each of the bags to convert them into filled, sealed bags as the bags are moved around the carousel;
- said transporting means comprising a picker mechanism having gripper means for receiving open-ended bag length elements traveling in said first direction and for gripping said elements to cause them to move in said second direction, said gripping means comprising at least one traveling belt.
