ABSTRACT:
A device (15) for centering a tubular fabric (10) comprises a central fixed supporting portion (16) located within the fabric. A pair of oscillating arms (17) each having an end mounted to said central fixed portion (16), are kept divaricated against the tubular fabric. A motor driven roller unit (18) is secured to the free end of each oscillating arm (17) and has an electric motor (19). Motors (19) control rotation, in the same direction of rotation, of respective supporting members (21) each fitted with a plurality of idle rollers (22). The rollers (22) are angularly equally spaced around their respective supporting member (21) and are free to rotate about respective axes of rotation transverse to the direction of advancement of the fabric. Rotation of supporting members (21) in the same direction causes the fabric to rotate, while oscillating arms (17) keep the fabric stretched.
