Abstract
This disclosure relates to a counter for elastic rings, comprising a screw having a spiral groove which is slightly wider than the width of an elastic ring and is slightly deeper than the thickness of the elastic ring. The screw has an open discharge end, and a plurality of sorting rollers are loosely mounted in series on a support shaft located above and parallel to the screw and are independently capable of rotation and vertical movement. The sorting rollers contact a spiral ridge of the screw, and are arranged such that while the screw is rotated and the elastic rings are fed to the feed end thereof, the elastic rings are loosely moved into the spiral groove of the screw by the sorting rollers, and then sequentially delivered from the discharge end of the screw to a counting means.
