The device for finishing the continuous field trimming of the surface of the head of at least one rail of a railway track comprises at least one finishing unit per line of rails. Each of these finishing units comprises a beam (1) on which are mounted so as to rotate at least two pulleys or wheels (4, 8) located just above the rail (3), around which pulleys or wheels is fitted an abrasive belt (5) working lengthwise on the rail. Between two of these pulleys or wheels (4) is a foot (12) acted on by an actuator (14) pressing against the said beam (1) and acting on the foot (12) with a set force so as to apply the abrasive belt (5) to the running surface of the rail (3) with no vibration. At least one of the pulleys (4) is rotated by a motor to drive the abrasive belt (5).
Le dispositif pour la finition du reprofilage en voie et en continu de la surface du champignon d'au moins un rail d'une voie ferrée comporte au moins une unité de finition par file de rails. Chacune de ces unités de finition comporte une poutre (1) sur laquelle sont montés de façon rotative au moins deux poulies ou galets (4,8) situés légèrement en dessus du rail (3), autour desquels est disposée une bande abrasive sans fin (5) travaillant dans le sens longitudinal du rail. Entre deux de ces poulies ou galets (4) se trouve un patin d'appui (12) soumis à l'action d'un vérin (14) prenant appui sur ladite poutre (1) et agissant sur le patin (12) avec une force déterminée pour appliquer la bande abrasive (5) contre la surface de roulement du rail (3) sans aucune vibration. Au moins une des poulies (4) est entraînée en rotation par un moteur pour mettre la bande abrasive (5) en mouvement.
