The tensioning rollers face each other and actuation elements are provided which act on at least one of the tensioning rollers to turn it about the corresponding axis in order to tension the knitted fabric which is formed by the needles and passes between the tensioning rollers. The tensioning device comprises first detection elements for detecting the degree of tension of the fabric in a region of the portion of fabric that lies between the needle work area and the tensioning rollers. The first detection device is operatively connected to the first actuation element in order to vary or maintain the rotation rate of the tensioning rollers as a function of the detected tension degree tension and of a preset tension degree.
