<p>A dyeing tube includes a plurality of coaxial rings (3) each of which is connected to the adjacent rings (3) through a plurality of pliable linking members consisting in a pair of opposing arcs (4, 4') having a wide bending radius, the chord of each arc being a length of the upper or lower surface of a ring (3), said pair of arcs (4, 4') being centrally united at a spacer (5) projecting above and below inside the two arcs (4, 4') for an overall height equal to the distance between two adjacent rings (3) in the compressed condition of the tube. The thickness of the arcs (4, 4') progressively increases in a symmetrical way from the tube central portion (A) towards the ends. <IMAGE></p> |
