ABSTRACT:
A vibratory material feeder including a vibrating gate, particularly suited for feeding fibrous materials. The invention includes a vibrating material feed tray having a section providing a tapered smooth transition from vertical to horizontal for material being fed, and a section including a vibrating gate. The vibrating gate is connected to a vibrating gate support member which is connected, by rotatable supports, to first and second relatively movable portions of the vibratory material feeder. As the material tray vibrates, the vibrating gate support member causes the vibrating gate to move with motion opposite to that of the vibrating tray, and with greater magnitude. The smooth transition from vertical to horizontal, combined with the synchronized motion of the vibrating gate, promotes uniform material flow and prevents material agglomeration, particularly for fibrous materials.
