Resilient element material for a vibratory feeder is molded of a resilient plastic resin to have a base and generally upright elements molded integrally with the base and having upper ends that cooperate to support objects being fed vibrationally. The upright elements are configured so they bend in the feed direction and brace against bending in a direction opposite to the feed direction. This can be done by providing abutments or buttresses adjacent the elements, or configuring the elements so that the weight of the objects places a load on their upper ends spaced toward the direction of feed from respective lines perpendicular to the base through the centers of the bottoms of the elements. The upright elements then bend consistently in the feed direction under the weight of the objects during vibration to convey the objects along. The elements can also be molded to be tapered and to incline from a perpendicular to the base toward the direction of feed to bend reliably in the feed direction.
