| (57) With a textile machine including a large number of yarn processing units that produce
packages, in spite of an attempt to make the yarn lengths of packages uniform on the
basis of a yarn speed detected for each unit by a yarn speed sensor, the yarn length
of an actually produced package varies among the units as a result of an inherent
error in the yarn speed sensor. The present invention provides a winder 100 including
a large number of winding units 1 each having a yarn speed sensor 7 that detects a
yarn speed, a sequencer 12 that calculates the yarn length of a winding package 4
on the basis of the detected value from the yarn speed sensor 7, and a winding device
20 that forms a winding package 4. The winder 100 includes a setting member 41 that
transmits correction information for each of the yarn speed sensors 7 to the corresponding
sequencer 12. Each of the sequencers 12 corrects the detected value from a corresponding
one of the yarn speed sensors 7 on the basis of the correction information to calculate
a correction value for a corresponding yarn speed to calculate the yarn length of
the corresponding winding package 4 on the basis of the correction value for the corresponding
yarn speed (Fig. 2).
