Yarn winding apparatus and method of producing a yarn package

摘要

A yarn winding apparatus having a fitting structure at connecting portion of a spindle (8) and a motor shaft (12), which fitting structure is constructed with a hole provided at the end surface of the motor shaft and an end portion of the spindle inserted into the hole or a hole provided at the end surface of the spindle and an end portion of the motor shaft inserted into the hole. At the connecting portion, the fitting structure forms a deflection control means for substantially conforming deflections of the spindle and the motor shaft with each other by supporting the spindle based on stiffness of the motor shaft. <IMAGE>
