ABSTRACT:
The device for reprofiling the head of at least one rail comprises a support (1, 2, 12, 13, 9) carrying at least one grinding unit (3, 4, 6, 7) pivotally mounted about an axis (8) extending parallel to the longitudinal axis of the rail (11). This grinding unit has a grinding wheel (3) driven in rotation by a motor (4) and structure (7) for displacing axially the grinding unit (3) to apply it against a side line of the head of the rail (11) and thus compensate its wearing off. It comprises structure (9, 10, 19, 20, 21) for displacing the axis of pivoting (8) of the grinding unit (3, 4, 6, 7) parallel to itself, in a direction transverse to the longitudinal axis of the rail (11). Servo-mechanism is provided to make dependent on each other the pivoting of the grinding unit (3, 4, 6, 7) and the displacement of its axis of pivoting (8).
