ABSTRACT:
A bobbin holder of a winder wherein a shaft carrying a bobbin holding disk or projection is supported in a bushing by needle or ball bearings which carry the radial load, and the lower end of the shaft is supported by a thrust receiving plate which in turn is supported by a thrust receiving ball disposed for rotation at the bottom of the bushing and for carrying the thrust load. Alternatively, the lower end of the shaft is terminated in the form of a truncated cone and is supported by more than three balls which carry both the radial and thrust loads. A flanged seal and a seal ring are mounted on the upper outside of the bushing to prevent the intrusion of cotton fibers and dust into a bearing chamber of the bushing.
