ABSTRACT:
A fine grinding device for the continuous reprofiling in situ of the surface of the head of at least one rail of a railway track includes at least one fine grinding unit per rail. Each one of these fine grinding units carries a beam (1) on which are mounted rotatably at least two pulleys (4, 8) situated slightly above the rail (3) and around which is arranged an endless abrasive brand (5) working in the longitudinal direction of the rail. Between these two pulleys (4) there is a biasing shoe (12) that contacts the rail over a rectangular surface and that is subjected to the action of a jack supported by the beam (1) and acting on the shoe (12) with a determined force for applying the abrasive band (5) against the head of the rail (3) without any vibration. At least one of the pulleys (4) is driven in rotation by a motor to set the abrasive band (5) into motion.
