Abstract
A relatively high speed packaging machine of the type in which a heated film is formed by application of pressure to provide an enclosure for encapsulation of articles on a substrate utilizes a conveyor, a heater and film transport means disposed above the conveyor. Pressure forming means and cutting means are movably supported on the frame for reciprocal movement along the frame and for movement vertically relative to the conveyor to effect forming of the film and cutting of the film into units. Drive means simultaneously drives the conveyor and film transport means as well as the pressure forming means and cutting means in movement towards the exit end of the conveyor. The drive means also returns the pressure forming means and cutting means and moves them in a vertical path relative to the conveyor. Control means operates the drive means to effect the times operation thereof while the conveyor moves continuously.
