  • Patent number: 4955656
    Abstract: A gripping device for nappy workpieces which is capable of handling both small and large pieces of textile materials. A gripping device is provided having a base part and a slidable part, between which is provided a substantially closed hollow to which pressurized gas is supplied through a series of slots. The slidable part is moved in such a manner that the slots are squeezed together and the gripping device grips the nap of the upper piece of textile material. Pressurized gas is led through the upper piece to the piece lying immediately below to ensure efficient separation of the upper piece from the piece below, and avoiding the inadvertant lifting of more than one piece at a time.
