Abstract:

This invention relates to a payoff device particularly suited for coiled wire which is packaged without a reel. The device includes a clamp assembly rotatably supported at one end by a frame which may be affixed to a truck or other vehicle. The clamp assembly has a mandrel featuring a plurality of clamp pads connected to a main rotatable shaft by a scissors linkage which may be stationary or may push the pads in a radial direction against the interior surface of the coiled wire. Two end plates support the coil laterally and one of the end plates is removable so that the coil can be placed on the clamp assembly. The clamp assembly is supported by a frame whose upper portion is rotatable such that the payoff direction can be changed. The device also includes a brake and a stop pin to prevent unwanted rotation of the clamp assembly and a locating pin to prevent the unwanted rotation of the upper portion of the support frame.
