First Claim
1. A method for automatically controlling a powder bagging machine, said powder bagging machine having a weighing means for measuring the weight of powder dispensed and a means for dispensing the powder into a container, said method comprising the following steps in sequence:
- (a) operating said dispensing means during a first stage at a predetermined high speed for a predetermined time,(b) measuring the weight of powder dispensed during said first stage and comparing said measured weight with a desired total weight,(c) operating said dispensing means during a second stage at a decelerating speed, the rate of deceleration determined by the measurement taken in step (b).

Abstract
Means and method for automatically controlling a powder bagging machine, said powder bagging machine having a weighing means for measuring the quantity of powder dispensed, and a means for dispensing the powder into a container, said automatic control means comprising a comparator means for sensing deviations in weight as measured by said weighing means, a control means for analyzing said weight deviations and for controlling the dispensing means. The method of the present invention comprises operating said means so as to effect a multi-stage filling cycle, the first stage comprising operating said dispensing means at a predetermined high speed for a predetermined time, the second stage(s) comprising controlled rate(s) of deceleration of said dispensing means, and the optional last stage comprising operating said dispensing means at a predetermined low speed or at a low rate of deceleration from a predetermined low speed until the desired weight of powder is dispensed.
