Abstract: A device for transferring tubular fabrics, particularly panty hose, the opening or mouth of which is fitted on support hangers which are spaced apart from one another and hold the mouth at an open position, and for transferring such tubular fabrics onto a rigid body adjacent to and aligned with the hangers by inverting the tubular fabrics on such rigid body. The device includes a slide longitudinally movable on a fixed guide, jaws mounted on the slide and includes four discrete rotable elements in two pairs on two discrete planes, a pan projecting forwardly of the slide and freely axially movable relative thereto against the action of a spring, plungers supported from the jaws which project for insertion in the mouth or opening of the tubular fabric as the slide moves forward, followed by lifting such fabric out of the support hangers when the jaws are spread out.
