ABSTRACT:
Apparatus for filling discrete open or valve type bags with metered quantities of flowable bulk material has a gravity flow duct the upper end of which receives metered quantities of bulk material and the lower end of which discharges successive metered quantities into discrete bags. The rate of gravity flow of bulk material in the duct is regulatable by an adjustable flow restrictor which is adjusted, each time a different bulk material is gathered into metered quantities, in such a way that the rate of flow is just below that rate which causes the descending material to clog the duct. This is ascertained by starting with an adjustment at a rate well below that which results in clogging and by stepwise increasing the rate until the period of discharge of a metered quantity abruptly increases to thus indicate that the duct is being clogged. The rate of discharge is then reduced to a value at least slightly below the rate at which clogging occurs to thus ensure that the periods of time which elapse during discharge of metered quantities of bulk material into discrete bags are as short as possible without risking clogging of the duct.
