<p>Apparatus is described for inhibiting fluid flow and fibre package (3) motion in a fibre blowing operation. The apparatus comprises a fluid flow passageway (8) with a valve (9), and a bypass passageway (7) for the fibre package (3) in the vicinity of the valve (9). A flexible membrane (11) is interposed between the fluid flow passageway (8) and the fibre bypass passageway (7), which membrane bears against the fibre package (3) and closes the bypass passageway when the valve (9) is closed.</p> |
