An apparatus for napping a textile material includes a plurality of rollers for advancing the material to be napped in continual longitudinal movement and a plurality of napping rollers arranged in contact with the material to be napped and adapted for rotational movement. The napping rollers includes one group of napping rollers arranged in contact with one side of the material and a second group of napping rollers arranged in contact with the opposite side of the material. The rollers for advancing the material and the napping rollers are operatively connected to each other. A drive for generating the movement of the material and rotation of the napping rollers is provided in the apparatus. A device for varying a speed and direction of the movement of the napping rollers to provide alternate oscillating movement thereof is arranged in the apparatus. The speed-varying device is connected to the drive to provide a periodical swaying movement of the material to be napped simultaneously with alternate oscillating movement of the napping rollers.
