Abstract:
This invention is directed to multiple sealing bars to seal articles moving on a conveyor (2) inside a sleeve (4) that forms a continuous film tube (5). Retracting conveyors act to collapse the tube between the articles so that the collapsed portion of the tube can be sealed. The synchronization of the sealing bars with the movement of retracting conveyors allows for a continuous motion machine where the products inside the film do not stop.
