Abstract

A method of turning a plurality of stackable cups to a position where the cups repose on their open and wider ends, the cups having a height which is less than the greatest diameter of the cups at their open ends, in which the cups are taken to a first zone on a continuously forwardly driven conveyor belt randomly assuming a position reposing on their bottom ends, reposing on their open ends or lying on one side. The cups are then moved through a second zone where those cups which are lying on one side are raised to a position where they repose on their open ends. Next, the cups are moved through a third zone where those cups reposing on their bottom ends are tipped over to a position where they repose their open ends. Finally, the cups are collected into a row and arranged after each other and led to a zone where the cups not reposing with their open ends on the belt are removed from the belt, whereafter the cups reposing on their open ends are led in a row to a position for stacking. The invention also relates to an apparatus for carrying out the method.
