ABSTRACT:
An improved powder feeder having a hopper with an opening in its bottom. A resiliently deformable element is positioned in the opening of the hopper. The element has a flexible exterior dimension and is suitably positioned in relation to the opening to prevent the free flow of material through the opening. The element is mounted on an axle having an axis of rotation. The element is capable of carrying a metered volume of material through the opening as it is rotated. The axle is connected to a variable speed motor. As the element turns, the material flows into the element and moves through the hopper opening in precisely metered amounts relative to the volume and the speed of rotation of the element.
