Abstract: A thread displacement device for displacing a thread on a winding body includes a thread guide, which, depending on a movement of the winding body, can be freely selectively moved back and forth along a curved path defined by guide means. The thread guide has a thread guide roller rotatably mounted about a thread guide roller rotational axis to guide and press the thread against the winding body, said thread guide roller being configured as a self-directing roller. The guide means includes a flexibly deformable traction means, which can be guided back and forth via deflection rollers and/or deflection rods and on which the thread guide is directly fastened.
