Abstract of the Invention A combined blousing, stripping and sealing operation is disclosed for providing increased speed and efficiency to a form, fill and seal packaging system. An AC/DC brushless servo motor 60, 50 is utilized for driving the stripping/sealing carriage 12, as well as operating the sealing jaws 30, 32 to form the bags B from a continuous film tube T. Each servo motor 60, 50 drives a crank 62, 36 that is coupled for oscillating movement in response to a programmable index controller 58. Drive linkage 63 connects the crank to the carriage/sealing jaws. The blousing function is provided by a pair of plates 54, 55 on the top of the sealing jaws. On the return movement of the carriage 12, the plates 54, 55 contact the bottom of the bag next in line to bulge the sides for receipt of the product. The programmable index controller 58 provides a signal to the carriage/sealing jaws in dependence on an external signal indicative of the selected bag size being packaged.
