Abstract
The method of forming an overwound thread transfer tail entails moving a thread guide carrier which supports a thread guide in a first direction against an abutment and permitting the thread guide carrier to recoil and thereby cause a return movement of the thread guide after striking said abutment. The apparatus for performing the method comprises a thread guide and a movable member movable in a predetermined direction and connected to the thread guide. An abutment serves for limiting movement of said movable member in such predetermined direction, and structure is provided for moving the movable member against the abutment in a manner such as to cause recoil of the movable member.
