ABSTRACT:
A machine and process function to fill cavities with metered amounts of particulate material. An applicator wheel includes a series of equally spaced apart peripheral pockets each having a perforated bottom wall, and a vacuum manifold inside the wheel includes a vacuum chamber for supplying vacuum to the perforated bottom walls of the pockets as the wheel rotates. Particulate material from a filling chamber of such material outside the wheel is withdrawn into the pockets by the vacuum chamber. A downstream vacuum relief on the vacuum manifold functions to discharge particulate material from the pockets into the cavities at a predetermined discharge location on the wheel. Adjustment structure is connected to rotatably adjust the position of the vacuum manifold within the applicator wheel to thereby advance or retard the discharge location depending upon the speed of the machine.
