Abstract
An improved stripping and sealing operation in a form, fill and seal packaging system is provided. Stepper and servo motors are computer controlled including by a 3-axis coordinator operating the X and Y motion of the sealing jaws, as well as the Y' motion of the film/tube feed. The Y motion is provided by oscillatory driving movement of the carriage to move the stripper/sealing jaws in a substantially constant modified sine wave profile. The Y' motion is variable and tracks the carriage to precisely size and form the bag. Blousing is also provided by tube/carriage relative motion also induced by varying the film/tube feed.
