  • Patent number: 4084306
    Abstract: An apparatus for transporting and wrapping pipe insulation comprising a frame and a pair of arms mounted on the frame for swinging movement about a longitudinal axis. A row of longitudinally spaced vacuum pads is suspended and on each arm a pair of transversly spaced rows of longitudinally spaced vacuum pads are suspended on the arms inwardly of the first-mentioned rows on said arms. Vacuum can be selectively supplied to the rows of vacuum pads. Means are provided for swinging the arms toward and away from one another whereby when the arms are extended and the vacuum pads are brought into engagement with a generally flat piece of insulation, the insulation is engaged and may be lifted and transported by manipulating the frame to bring the insulation adjacent a length of pipe and the arms may thereafter be swung inwardly to wrap the insulation about the length of pipe.
