Method and apparatus for continuous hammer of the railway rail rectification stage.

摘要

1. Method for the continuous on track reprofiling of at least one rail (12) of a railway track according to which one displaces along the track at least one assembly of grinding units (10) angularly displaced the ones with respect to the others and submitted to the pressure with which each grinding unit (10) is applied against the rail, characterized in that the said pressure is automatically controlled in function of at least one parameter which represents the dimensions of the sides (L) of a predetermined polygon (6) circumscribed to a reference profile (7) and the sides of which (L) are parallel to the corresponding active surfaces of the grinding wheels of the grinding units.
