  • Apparatus for stretching tubular material with a least one closed end on a stretcher
    Patent number: 5316188
    Abstract: An apparatus for stretching tubular material with at least one closed end on a stretcher, in particular for stretching stockings, pantyhose, and the like on an elongated stretcher, is described, in which the tubular material is pulled onto the stretcher by means of belt drives. Each stretcher has at its lower end an end member at which there is provided a sensing device by means of which the belt drives are shut off as soon as the closed end of the tubular material arrives in the region of the end member. With the sensing device, the belt drives are reliably shut off regardless of the length of the tubular material being pulled on, which not only prevents slippage of the drive rollers of the belt drives, but also ensures complete pulling onto the stretcher.
