ABSTRACT:
A positive flow vibratory feeder uses a support element extending along a feed path and vibrated in a plane perpendicular to the support element and extending along the feed path. The support element is covered with a feed pile material having resilient bristles of uniform length uniformly inclined toward the direction of feed from a plane generally perpendicular to the support element and transverse to the support element. A fixed holder generally parallel with the support element and spaced from the feed pile material is covered with pile material having resilient bristles of uniform length extending toward the feed pile bristles. The tips of the holding pile bristles are spaced from the tips of the feed pile bristles by slightly less than the thickness of the objects being fed to hold the objects in engagement with the tips of the feed pile bristles during vibration, and the holding pile bristles are inclined toward the direction of feed to cooperate with the feed pile bristles to produce a positive flow for said objects.
