Method and means for mounting a drive roll in a high speed winder

摘要

The present invention provides a way of mounting a drive roll in a high speed winder, in which a drive roll bracket for holding a drive roll is pivotally supported by a pivot whose axis is an intersection line between a vertical plane equally dividing a distance between opposite remote end surfaces of a wound thread package and a horizontal plane that is tangential to a bottom surface of the drive roll or a horizontal plane in the proximity thereof, and a press contact force between said drive roll and the bobbin holder shaft or wound thread package is applied entirely by the intermediary of said pivot.
