Abstract
A bobbin trace system in which a bar code for distinguishing a bobbin is affixed on a tray on which the bobbin to be fed from the spindle on the fine spinning frame to the winder is inserted upright, the bar code is read by a bar code reader and at the same time the yarn characteristic of the bobbin of the code is detected, the yarn characteristic thus detected is transferred to the controller which controls the operation of the winder, and the controller reads the code of the tray to be fed to the winder and feeds the bobbin characteristic corresponding to this code back to the winder, thereby controlling the operation of the winder on the basis of the bobbin characteristic thus fed back.
