Abstract: A mechanism for automatically orientating cup bodies includes a cup-body rotating element, an element for measuring a peripheral configuration of the side wall of a cup body, and a central control element for comparing the peripheral configuration of the side wall thereof with a peripheral configuration of the side wall of a sample cup body as determined in advance. The central control element determines whether the two peripheral configurations coincide with each other, and determines the angle by which the cup body is to be rotated to orientate it in a selected direction for the connection of a handle thereto at a predetermined position thereon if the two peripheral configurations do not coincide with each other. Then, the central control element rotates the cup-body rotating element by the required angle to orientate the cup body in the selected direction.
