Abstract
A device and method for applying a liquid to at least one advancing yarn which is guided over a surface of a driven godet in contact therewith. A liquid is supplied through a plurality of capillaries to the surface. To this end, the pore-sized openings of the capillaries are evenly distributed on the godet surface being wetted.
Claims20
A method of applying a liquid to an advancing yarn comprising the steps of
- providing a godet which defines a cylindrical outer surface and a central axis, and a plurality of substantially radially directed capillaries formed in the godet and communicating with the outer surface so as to define openings on the outer surface which are distributed circumferentially thereabout, with the capillaries having a diameter ranging between about 10 μm and 1000 μm, and with the godet being mounted for rotation about said central axis, and a liquid supply system comprising an annular groove extending axially into said godet and being radially offset from the central axis of the godet, with the annular groove communicating with said capillaries,
- guiding the advancing yarn into contact with the outer surface of the godet while causing the godet to rotate about said central axis, and while
- metering a liquid into the annular groove and through the capillaries and openings and onto the outer surface of the godet and so that the liquid is applied to the advancing yarn.

- a plurality of substantially radially oriented capillaries formed in the godet and communicating with the outer surface so as to define openings on the outer surface which are distributed circumferentially thereabout, with the capillaries having a diameter ranging between about 10 μm and 1000 μm, and
- a liquid supply system connected to the capillaries for supplying a liquid to the capillaries and thus to the openings on the outer surface, said liquid supply system including an annular groove extending axially into said godet and being radially offset from the central axis of the godet.
