Abstract

Un modulo di stiro a più stadi comprende un certo numero di coppie di rulli di stiro comprendenti almeno una coppia di rulli di stiro superiore e almeno una inferiore di riferimento, ogni coppia di rulli di stiro comprendendo due rulli aventi assi sostanzialmente paralleli e sostanzialmente la stessa lunghezza assiale e tutte le coppie di rulli di stiro avendo assi sostanzialmente paralleli disposti sostanzialmente perpendicolari al piano di riferimento: tale disposizione sfalsata delle coppie di rulli di stiro essendo definita sostanzialmente da uno sfalsamento longitudinale di ognuna delle coppie di rulli di stiro superiore rispetto ad una coppia di rulli di stiro inferiore adiacente. Tale sfalsamento corrispondendo sostanzialmente alla lunghezza di lavoro di una coppia di rulli di stiro superiore: tale piano teorico di riferimento avendo un'inclinazione tra 20 e 60 gradi rispetto ad un piano orizzontale.A multi-stage stretch module comprises a certain number of pairs of stretch rollers comprising at least one pair of upper and at least one lower reference roll, each pair of stretch rollers comprising two rollers having axes that are substantially parallel and substantially the same axial length and all pairs of stretch rollers having substantially parallel axes arranged substantially perpendicular to the reference plane: this offset arrangement of the pairs of stretch rollers being defined substantially by a longitudinal offset of each of the pairs of stretch rollers greater than a pair of adjacent lower stretch rollers. This offset corresponding substantially to the working length of a pair of upper drawing rollers: this theoretical reference plane having an inclination between 20 and 60 degrees with respect to a horizontal plane.
