Abstract: For use on a form, fill and seal bagging machine a left side bag gripping member and a right side bag gripping member are located in association with a movable component of the bagging machine as, for instance, the head seal.

Abstract: A Stirling engine heater head is constructed to provide an annular heat exchange region defined between a pressure vessel sidewall and the engine displacer cylinder. From an external manifold, through which a heated fluid flows, either heat pipes or heat exchange tubes are sealingly introduced into the heat exchange region. Thermal energy is thus transferred to the engine working fluid, while the heated fluid is maintained isolated from the vessel walls and the displacer cylinder.
