Abstract:
    A method for the continuous gradual stretching and drying of industrial hides and similar products comprises at least one step (a) involving the initial partial drying of the completely wetted hides supplied following a treatment with liquids, such as tanning, retanning or dyeing, until their relative moisture content is reduced to between 45 % and 65 %, at least one step (b) involving the final stretching of the hides by means of localised mechanical stresses able to recover the shrinkage resulting from the partial drying thereof, characterized in that, after said initial partial drying step (a), at least one intermediate stretching step (c) is performed, followed by intermediate partial drying (d) followed by at least one intermediate stretching step (e) before proceeding to said step (c) involving the final drying and heat-fixing of the hides.
