ABSTRACT:
A method and apparatus is disclosed for receiving a helical formation of rings free falling from the delivery end of a conveyor and for gathering the rings into an upstanding cylindrical coil, The free falling rings encircle a vertically disposed guide and are supported initially on elevated intercepting elements. The interceptor elements are gradually lowered past a coil plate onto which the accumulated rings are transferred. The coil plate is then lowered to accommodate continued formation of the coil, and the intercepting elements are returned to their elevated position.
