A machine and method for the manufacture of a continuous production of pneumatically filled packaging pillows for use as void fill packaging for the safe shipping of articles. A strip of flattened preformed film material with a repeated sealing pattern is advanced along a path through the machine and include a common inflation channel that is guided onto a longitudinally extending inflation tube at a first station. The inflation tube has an orifice through which pressurized air is expressed in controlled fashion to inflate pillow chambers that emanate off the common inflation channel of the film material. The film material is advanced to a second station where continuous longitudinally extending heat seals are formed in the film material in a manner to trap and confine a quantity of air inside the inflated pillow chambers. The film material is then advance to a third station where the common inflation channel is slit open in order to release the film material from the inflation tube of the machine. An advantageous aspect of the invention is that the film material is advanced along the path from station to station in a continuous motion.
