Abstract

In a textile-processing operation wherein a filament is displaced longitudinally continuously past a treatment station and a liquid is applied to the moving filament at the station, a supply of the liquid is held in a container spaced from the station and connected via a conduit to an applicator at the station. Space above the liquid in the container is filled with a gas that is devoid of free oxygen and that is in direct contact with the liquid. This gas above the liquid is pressurized in the container to controlledly force the liquid from the container through the conduit to the applicator at the station. The liquid is kept out of contact with oxygen until it actually has been applied to the filament. In fact the filament is passed over a small-diameter orifice formed in a guide and the liquid is forced from the orifice. The filament directly engages the guide at the orifice and covers the orifice so that the liquid does not contact the ambient air until after it is applied to the filament.
