<p>1. Device for the reprofiling of rails by continuous milling, comprising a support member (8) having a relative linear displacement with respect to a fixed or movable rail (1), the said support member (8) comprising before the milling tool (5) in the direction of displacement, reference guiding means (6) for the cutting depth of the tool pass bearing against the upper face of the rolling surface (2) of the rail and reference guiding means (9) of the lateral cutting depth of the tool bearing against the lateral face (2b) of the rolling surfaces of the rail (2) characterized by the fact that the tool cutting depth guiding means of the tool are formed of a circular plate (6) mounted for free rotation on a vertical, or slightly inclined, shaft (7) fast with the support member (8) ; that the lateral cutting depth guiding means for the tool are formed of a conical roller (9) mounted for free rotation on the same shaft (7) as the said plate (6) ; and by the fact that the tool is constituted by a shaped milling cutter (5) working simultaneously on the upper said surface and on its lateral face.</p> |
