Abstract: An apparatus and a method for sorting out shredder waste allows for lower sorting cost and higher sorting accuracy to be achieved. Shredder waste is fed into a hopper to untangle it. The untangled shredder waste is quantatively supplied into a separating duct wherein the shredder waste is subjected to steam by a steam injector so as to be further untangled. The shredder waste that has been further untangled in the separating duct is carried, while being agitated, into a striker. In the striker, the shredder waste is struck by chains that swing as a rotating shaft rotates, so that harness waste or the like is separated from the shredder waste. The separated harness waste or the like is transferred onto a conveyor through an outlet. On the conveyor, the harness waste is separated from heavy materials, such as rubber and rigid plastics.

Abstract: A trolley wire is paid out under tension from a drum on a traveling railroad car and is guided by a guide roller device on a following car to be hung by temporary hangers on a previously installed messenger wire, the guide roller device having a cradle rotatably supporting several transverse horizontal rollers and vertical rollers which respectively form a horizontal guide surface and two opposed vertical guide surfaces of large radii of curvature to prevent permanent bend sets in the trolley wire. The cradle is rockably supported on transverse pivot pins so that it can swing and optimally adapt to changes in the wire direction, and the mechanism thus supporting the cradle is also movable in the up-and-down directions and the in the transverse left-and-right directions.
