A device for a turning machine automatically separates partially-turned stockings from completely-turned stockings. All stocking leaving the machine are guided on a slide to a pneumatic ejection tube with photoelectric cells and reflectors. The distance between two photoelectric cells is adjusted so that, when a stocking is completely turned, its point and its edge simultaneously darken both cells. A cylinder is then actuated so that a guiding slide adopts a discarding position and the stocking falls in to a container. The guiding slide then returns to its initial position. When stocking is not turned, both photoelectric cells are not darkened simultaneously, the cylinder is not actuated, the guiding slide remains in the vertical position and the stocking falls into a different container.
