A device for correcting transverse position of a fabric which is continuously fed in longitudinal direction into a treating machine, such as a dyeing machine, which comprises a correcting roll around a part of which said fabric is carried while it is fed to said machine, said correcting roll including a shaft, means for driving said shaft, flanges fixedly formed on said shaft adjacent its opposite ends, a plurality of slidable bars so supported by said flanges that the bar is fixed relative to the flanges in the peripheral direction but slidable relative to the latter in the axial direction, a cylindrical cam for imparting reciprocal sliding motion to the respective slidable bars and being freely rotatable on said shaft, a first stop means for stopping said cylindrical cam in first position where sliding motion is exerted to the slidable bars in one direction at said part of the correcting roll, a second stop means for stopping said cylindrical cam in second position where sliding motion is exerted to the slidable bars in the opposite direction at the same part of the correcting roll and selvedge-sensing means for sensing the selvedge of the fabric to produce correcting signal which is applied to one of the first and second stop means to stop the cylindrical cam in one of said first and second positions.
