Abstract

A spindle shaft is flexurally elastic at its shank part mounted in a bearing sleeve. The spindle shaft carries a belt-engaging wharve which is arranged underneath the neck bearing and to which a drive belt engages to rotate the spindle shaft. The bearing sleeve is arranged to have radial play within a spindle housing 10. The bearing sleeve is fastened at its lower end via a flexurally elastic tilting joint 40 to the spindle housing 10 connected rigidly to the spindle rail. The pulling force of the drive belt engaged to the wharve during operation deflects the bearing sleeve radially by tilting it about the tilting joint. Such deflection brings about, on the other hand, a pivoting of the bobbin-carrying upper part of the spindle shaft about the neck bearing in the opposite direction as a result of the bending moment occurring on the shank part, an inclination of the spindle shaft with its upper part is thus avoided.
