1. A machine for winding a web material into a plurality of secondary reels, the machine comprising:
a web material feeding path;
a winding station, adapted to receive one or more secondary winding cores and to form secondary reels of web material therearound; and
an in-line measurement arrangement for measuring the Poisson's ratio of the web material, wherein the in-line measurement arrangement for measuring the Poisson's ratio comprises in combination:
a first measurement device adapted to measure a first feeding speed of the web material in a first position of the web material feeding path of the web material towards the winding station;
a second measurement device adapted to measure a second feeding speed of the web material in a second position of the web material feeding path of the web material towards the winding station, downstream of the first position of the web material feeding path;
a first device adapted to acquire information on a first width of the web material in the first position of the web material feeding path; and
a second device adapted to acquire information on a second width of the web material in the second position of the web material feeding path.
