Abstract
A vibratory feeder for cohesive particulate solids such as powders and the like. A conveyor frame supports a flexible conveyor membrane and is excited by a vibrator. The vibrator produces standing waves defined by nodes in the sectional configuration of the membrane transverse to the direction of material flow, with the sections between the nodes effecting periodic, alternately inverting flexures to release adhering solids.
