Patent attributes
This is a double acting, multi-lane machine and method for the forming, filling and sealing of plastic or paper film pouches of various sizes commonly used to hold liquid viscous, dry, particulated or powdery materials or other substances. The machine includes a four roll film dispensing station, a multi unit pump or dispensing station, one of each double acting stations such as side seal station, pull wheel station, cross seal station, and cross cut station. The invention provides for production of a multitude of pouches in a manner of two sets of two films allowing to double the production output of current machinery without any change to cycle time or increase of operational time. Coordination and movement of the various stations is accomplished through electronic computer control, working in conjunction with multiple motion controlling devices such as servo motors, air cylinders, belts, linkages and the like. The machines stations and components are adjustable or interchangeable so that pouches of various lengths and widths may be formed.
