Abstract

Verfahren zum Schleifen der Lauf- und/oder Führungsflächen von Schie­ nen oder dgl., bei dem die Laufflächen durch ein endloses, umlaufendes und gegen die Laufflächen bewegbares Schleifband geschliffen werden, wobei die Lauf- und/oder Führungsflächen der Schiene von einem quer zur Längsachse der Schiene umlaufenden und die Lauf- und/oder Füh­ rungsflächen unter Vorspannung zumindest teilweise umschlingenden Schleifband geschliffen werden, sowie Vorrichtung zur Durchführung des Verfahrens, bestehend aus einer auf zumindest einer Schiene des Glei­ ses geführten fahrbaren Schleifmaschine mit einem endlosen Schleif­ band, welches über eine Antriebsrolle und einer mit Abstand davon an­ geordneten Umlenkung umläuft und über dieselben gegen die zu schlei­ fenden Flächen der Schiene bewegbar ist, dadurch gekennzeichnet, daß die Umlenkung aus zwei verhältnismäßig geringen Abstand voneinander ausweisenden Umlenkrollen (16, 17) gebildet ist, daß die Achsen der Umlenkrollen (16, 17) und der Antriebsrolle (19) parallel zur Längs­ achse der Schiene (3) angeordnet sind und somit das Schleifband (22) quer zur Längsachse der Schiene (3) umläuft und daß zumindest eine Um­ lenkrolle (16, 17) zur teilweisen Umschlingung der Flächen (2) der Schiene (3) unter die Oberkante der Lauffläche (2) der Schiene (3) absenkbar ist. Method for grinding the running and / or guiding surfaces of Schie NEN or the like, in which the treads by an endless, revolving and sanding the movable sanding belt against the treads, wherein the running and / or guide surfaces of the rail from a cross to the longitudinal axis of the rail and the running and / or Füh around prestressing at least partially wrapping around Sanding belt are sanded, and device for carrying out the Method consisting of one on at least one rail of the slide This guided mobile grinding machine with an endless grinding tied, which via a drive roller and one at a distance from it orderly redirection revolves and about the same to be worn fenden surfaces of the rail is movable, characterized in that the deflection from two relatively small distance from each other Identifying pulleys (16, 17) is formed that the axes of the Deflection rollers (16, 17) and the drive roller (19) parallel to the longitudinal axis of the rail (3) are arranged and thus the grinding belt (22) rotates transversely to the longitudinal axis of the rail (3) and that at least one order Steering roller (16, 17) for partially wrapping the surfaces (2) of the Rail (3) under the upper edge of the tread (2) of the rail (3) is lowerable.
