Abstract : Apparatus for pneumatically pulling an optical filament from test bobbin and winding the optical filament onto the surface of a non-rotating spool. The filament is guided about the surface of the spool by one or more streams of fluid at supersonic flow and is wound into a groove in the cylindrical surface of the spool. The filament is wound onto the supply bobbin so that withdrawal of the filament from the supply bobbin imparts a twist to the filament as it is withdrawn and the filament is wound onto the spool in a direction which imparts a twist to said filament in the opposite direction to that the twist imparted by pulling the filament from the supply bobbin is offset by the twist imparted to the filament while winding the filament on the spool.
