Abstract

In order to be able to locate stuck rollers of a roller way as early as possible, with longer operational interruptions being avoided and the demounting of constructional parts of the roller way being not necessary, an arrangement for this purpose includes a supporting body which is movable along the roller way and carries a frictional head. The frictional head is pressable against the surface areas of subsequently arranged rollers. Means are provided for recording and measuring a difference between the velocity of the supporting body with which the latter is moved along the roller way and the velocity of the frictional head getting into contact with a roller.
