Method and arrangement for feeding, with yarn of constant absorbed length, a textile machine operating on a plurality of yarns
Abstract:
A method for feeding a plurality of yarns with constant values of fed length to a textile machine, each yarn unwinding from a spool and cooperating with a feed device, arranged to maintain the tension of the yarn at a predefined constant value before being directed to the textile machine. At least one control unit controls the feed to this machine such that an absorbed yarn length value to be maintained for each yarn fed to the textile machine is set or self-learnt. After measuring an actual value of the yarn length absorbed by this machine and comparing it with this predefined value, the control unit acts upon one or more feed devices and modifies the tension value of the corresponding yarn in order to make these absorbed yarn length values equal to the predefined value. A method for implementing this method is also claimed.
