Abstract
An improved system for applying internal treatment gas in the manufacture of glassware such as bottles or the like. An independent primary treatment system and backup treatment system are disclosed, with each treatment system monitoring itself to detect malfunctions. The backup system is automatically actuated whenever the primary system malfunctions. Simultaneous malfunctions of both systems cause glassware to be rejected from the conveyor line for a predetermined period, producing a gap which pinpoints the arrival of possibly untreated ware.
