ABSTRACT:
A method and winding apparatus for detecting feed bobbins having feed properties that do not correspond to a predetermined quality when winding feed bobbins onto cross-wound bobbins in an automatic bobbin winding machine is disclosed. The method comprises the steps of measuring the winding speed, counting yarn breaks before a predetermined threshold speed is reached for forming a yarn break count, detecting the quality of a given feed bobbin by comparing the yarn break count with a predetermined number and determining that the given feed bobbin has not attained a predetermined quality if the yarn break count reaches the predetermined number; if the quality is not attained, the given feed bobbin is rejected and the winding process is continued with a new feed bobbin.
