ABSTRACT:
A yarn winder provided with a long spindle (1) having a length of, for example, more than 800 mm, and free from vibration even when used at a high working rotation is provided by various aspects of the present invention. According to a first aspect, the dynamic unbalance of the spindle (1) is corrected by field-balancing in at least three planes including the mid-portion of the spindle (1) by an influence coefficient matrix method. According to a second aspect, the respective spindle (1, 14) mounted on a revolving drum (9) has a natural frequency different from each other so that no resonance occurs when the two spindles (1, 14) are rotated at substantially the same rotational speed. According to a third aspect, a bobbin holding portion (2) of the spindle (1) is formed by two cylindrical hollow bodies (103, 104) each having shorter length that can be easily machined without eccentricity. The rearward cylindrical hollow body (104) has a thicker wall thickness in a region closer to a connection (130) to the forward cylindrical hollow body ( 103) and a thinner thickness in a region farther therefrom, so that a weight of the cylindrical hollow body (104) does not adversely influence the vibration of the spindle. Also, an improved method for donning bobbins (115a through 115d) on the spindle (1) without eccentricity by the use of a stop (124) for providing a vacant distance (P) adjacent to the topmost bobbin (115d) before the same occupies a normal working position.
