Abstract
Abstract A device for removing flash from rails after resistance butt welding, mounted on a welding machine case and split along the vertical axis of the rail, comprising three cutters embracing the rail along the entire cross-sectional perimeter thereof and coupled with a hydraulic cylinder drive, one of said cutters is pivotally mounted on said case, split along the vertical axis thereof and contacts the rail rolling surface, while the two side cutters which embrace the sides of the rail head, the web and the base flange of the rail are arranged symmetrically relative to the vertical axis of the case and hinged thereto, the top portions of said side cutters being linked by an articulated rod.
