ABSTRACT:
A bobbin revolver for winding textile filaments has a rotatable chuck carrier with a plurality of bobbin chucks. The carrier is rotatable on a central shaft to urge the chucks successively towards a friction drive drum which rotates bobbins on the chucks to wind filament packages thereon. A fluid coupling, comprising co-axial, relatively rotable parts having communicating passages therethrough, is provided around the shaft to pass pressure fluid to and/or from devices on the carrier. The fluid coupling is arranged so that there is no relative rotation of its parts during winding of a package, thereby avoiding disturbance of the contact pressure between a package and the friction drum through sliding friction between the coupling parts.
