(+9.10.87, 8.12.87, 27.1.88, 8.3.88, 22.4.88(2), 25.5.88, 9.6.88-DE-734235, 741544, 202267, 807535, 819534, 813602, 817639, 819675) Yarn winder comprises at least one traverse guide which reciprocates between end reversal points, at each of which is an energy storing unit which receives kinetic energy from the traverse guide, and then returns the energy to the guide to accelerate its reversal. The energy storing unit comprises a rotational mass, of pivot amplitude defined by a stop pin and pref. loaded by a spring. Pref. the traverse guide is on a slide coupled alternately to upper and lower runs of a moving endless belt, or to the top runs of two oppositely moving belts.
