Abstract

Abstract A product packaging apparatus for the automated conveyance and packaging of predetermined quantities of products or materials in individual, flexible bags. The apparatus comprises an infeed conveyor for feeding a flow of material to be packaged to a packaging means and means for shutting off the flow of material from the infeed conveyor to the packaging means. The packaging means includes a receptacle, weighing means, support means for holding a plurality of flexible bags beneath the receptacle, closure means for opening, filling, and removing the bags, and a control means associated therewith for controlling the operation of the above means for shutting off the flow of material from the infeed conveyor to the packaging means. Means are included on the closure means for grasping each bag to be filled to keep the bag open and for directing a stream of air into the bag to initially open the same.
