Abstract
A spout and hood assembly for an air flow bag packer in which the spout consists of an inner product supply tube surrounded by a shell providing a vent area to which a vacuum is supplied to evacuate the air from the bag as it is filled. The shell is tapered and oval-shaped to conform to the bag sleeve and so that the vent area cross section increases toward the vacuum source to prevent plugging of the vent area. The bottoms of the supply tube and the shell engage one another to reduce the possibility of any product escaping through the vent system during the filling cycle. The spout is affixed to and surrounded by a generally cylindrical dust hood which is also vented to a dust collection system. A dust shield, attached within the hood, surrounds the spout with a clearance so as to provide a venturi effect to better draw any dust into the dust collection system.
