Abstract
A method and apparatus is disclosed for supplying a predefined quantity of bulk material to a packaging system. An amount of bulk material which closely approximates the desired package weight is discharged from a surge bin into a loss-in-weight feeder. Accurate single package weight loading of the loss-in-weight feeder yields a lower percentage of weight variance during feeder discharge than more heavily loaded feeders. In addition, the apparatus includes weight bearing springs mounted within the weighing mechanisms of the loss-in-weight feeder such that the weighing mechanisms are not damaged by overloading. The method of accurate filling of the loss-in-weight feeder prior to discharge and the spring protected loss-in-weight feeder cause package portions having optimal weight variance to be supplied for packaging.
