<p>PURPOSE:To obtain the subject apparatus free from the troubles such as electrical shock of worker and ignition of fly waste by spark by connecting a power source to a reel, connecting the reel to an ending work truck via a cord and constantly applying a rotational force to the reel in the direction to wind the cord. CONSTITUTION:An ending work truck traversing along each unit of plural spinning units arranged in a row is supplied with electrical power by the subject power feeding apparatus having the following structure. A power source is connected to a reel 13, the reel 13 is connected to the ending work truck 2 through a cord 14 and the reel 13 is constantly forced by a forcing apparatus 21 in the direction to wind the cord 14. The cord 14 is wound on the reel when the ending work truck 2 is approaching the reel and, on the contrary, the cord is delivered from the reel 13 by rotating the reel against the winding force when the ending work truck 2 is separating from the reel. Supply of electric power to the ending work truck can safely and smoothly be performed by this apparatus.</p> |
