Abstract

A vibration or shaking feeder combined with a drum which is rotated at high speed is disclosed. The vibration feeder includes a container having a helical ledge around the inner wall of the container for making articles in the container travel to rise up the helical ledge by vibratory motion of the container. The articles advanced up to the uppermost ledge are transferred to the outer drum rotated at high speed and fed to a next stage for further processing.
