ABSTRACT:
An automatic or fully automated machine for fabricating flexible containers sometimes known as squeeze containers. The containers are fabricated from flexible plastic tube stock. The machine embodies stages or stations arranged in line at which operations are performed on the stock material, the final operation being the filling and sealing of the container. The stations include an initial heating station for producing the desired flexibility in the material. As the stock is advanced, an initial slit is made part way through the tubing. Initial sealing is performed at a further station which fabricates the discharge end of the container. The stock is advanced in steps. At a final station, the fabricated container is filled and sealed. All of the operations are automated and are sequenced by way of automatic, pneumatic, and electrical controls.
