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.
A device for the in situ continuous fine reprofiling of a surface of at least one rail of a railway track, including four fine grinding units that each include a beam on which are mounted rotatably at least two pulleys for being situated slightly above a rail when the device is operating and around which is arranged an endless abrasive web for moving in a longitudinal direction of a rail when the device is operating, wherein between two of the pulleys there is a biasing shoe subjected to the action of a jack supported by said beam and for acting on the biasing shoe with a force to bias the abrasive web against a rail when the device is operating, without any vibration, wherein at least one of the pulleys is driven in rotation by a motor to drive the abrasive web into motion, and wherein each of said fine grinding units is mounted tiltably on a central support that is carried by two lifting jacks and a drawbar.
