An apparatus is disclosed for producing a serial flow of balls comprising a ball feeding apparatus cooperating with means for rotating it about an axis. The apparatus comprises: (a) a container for receiving balls to be fed having a wall symmetrically disposed about said axis and a base fixed to and enclosing one end of this wall, the base having at least one outlet port extending therethrough and spaced along its periphery; and (b) at least one tubular member corresponding to the port, the member being fixed at one end to the base at the port, curving away from the base and towards the axis, for leading balls away from the container to an outlet at the other end of the tubular member. The tubular member has its outlet in closer proximity to the axis than the port on the container base.
