Abstract:
A method of threading an advancing yarn onto a rotating bobbin tube at the commencement of a winding operation wherein a traversing mechanism traverse the advancing yarn along the rotating bobbin tube in define a traverse range, and comprising the steps ofguiding the advancing yarn by means of a yarn guide located at a threading position which is adjacent one end of the rotating bobbin tube and outside the traverse range,moving the yarn guide and the advancing yarn axially along the bobbin tube from the threading position to the traverse range so as to cause the advancing yarn to be transferred to the traversing mechanism, and so as to form a transfer tail wind on the bobbin tube between the threading position and the traverse range, andcontrolling the speed of the movement of the yarn guide as it moves along the bobbin tube from the threading position to the traverse range as a function of the winding speed such that a predetermined number of winds are deposited on the bobbin tube within the transfer tail wind.
