Abstract
The spindles of a flyer spinning frame are each mounted in respective chambers which are defined by telescopically slidable rings. The lowest ring on each sleeve is sealingly fixed on a spindle rail, while the uppermost ring on each sleeve is attached to a common, vertically movable support. The chambers, which are open at the top, are connected to the suction side of a ventilating fan by ducts, which extend through the spindle rail, and by flexible lines.
