<p>The ironing roller (10) comprises a first annular chamber (4) in communication with an inlet (5) and an outlet (6) arranged to rotate about a longitudinal axis (E), where said first annular chamber (4) forms a passage through which a heat carrying fluid heated by heating means located inside the ironing roller (10) circulates, a circuit external to the annular chamber (4) being arranged to lead the heat carrying fluid from the outlet (6) to the inlet (5) of the chamber (4). A second annular chamber (8) adjacent and coaxial to said first annular chamber (4) is provided, said two annular chambers (4, 8) being intercommunicated for the circulation of the heat carrying fluid from one of said annular chambers (4, 8) to the other, and where one of said annular chambers (4, 8) carries out a heat uptake function and the other one carries out a heat transfer function.</p> |
