Abstract
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 is utilized for driving the stripping/sealing carriage, as well as operating the sealing jaws to form the bags from a continuous film tube. Each servo motor drives a crank that is coupled for oscillating movement in response to a programmable index controller. Drive linkage connects the crank to the carriage/sealing jaws. The blousing function is provided by a pair of plates on the top of the sealing jaws. On the return movement of the carriage, the plates contact the bottom of the bag next in line to bulge the sides for receipt of the product. The programmable index controller provides a signal to the carriage/sealing jaws in dependence on an external signal indicative of the selected bag size being packaged.
