ABSTRACT:
A method of and apparatus for dispensing pre-determined proportions of two or more different materials from supplies thereof, comprising the steps of dispensing one of the materials onto a moving conveyor band adapted gravimetrically to sense the rate of supply of that material, and when the required rate is sensed as by a strain gauge, dispensing a second material onto the band and sensing the rate of supply of the second material until the required rate is established, continuing the foregoing procedure until all of the materials are being dispensed in accordance with the desired pre-determined proportions and thereafter continuously or intermittently monitoring the composite supply, and in the event of a variation therein, arresting the supply of materials one or more at a time until the source of variation has been detected and corrected, the supply of materials then being continued.
