Abstract: To bring about selection of the loops of heddles of the flat type with open heads, individually from the packet of loops hanging on a track whose horizontal guides pass through both heads, upper and lower, of the loops, use is made of: a binary track which guides the loops, having two sections joined together by a step descending in the direction of the heddling zone; and, beyond said step: a plate for stopping the packet of loops in such a way that that loop which comes in turn to the front of the packet and which is pushed against said plate, is unsupported by the track; and, above said step and tight against said plate: a flat-headed vertical blade only slightly thinner than one loop and having reciprocating motion, which blade acts axially on the peak of said loop that is unsupported by the track in such a way as to cause it to drop down said step onto the lower leg of the track and enable it to be selected from the packet; and, at the side of said step, a pusher, having horizontal reciprocating motion, w
