This invention relates to an improved device
for applying liquids for the treatment of ?la
mentary material and is particularly concerned
with the application of liquids to running lengths
of single ?laments, bundles of twisted or un
twisted ?laments, yarns and the like.

excessively small calibre since it is not intended
to use correspondingly smaller calibre ori?ces 15 to form a jet so that it is substantially free of
and/or reduced pressure to prevent the appli
cation of a needlessly excessive amount of liquid.
Under these conditions, the ori?ces tend to clog
with the result that the liquid is not applied
in as uniform quantities as desired unless fre
quent cleaning of the ori?ces is performed. '
It is an object of this invention to provide
a device for applying liquids to ?lamentary ma
terial which will be substantially free of clog
ging and which applies the liquid to the ?la
mentary material with a minimum of frictional
contact therewith. It is a further object of the
invention to provide a form of liquid applying
_ apparatus which is capable of the maximum ef
clogging. The liquid applying section is brought
down substantially to a point l0 which over-hangs
the trough or groove 3 in the body of the device.
This pointed formation is shown more or less '
as a pyramidal body, but it could as wéll be
conical or of ‘any other shape provided it ter
minates in substantially a ‘point. This pointed
structure serves to guide substantially all of the
liquid coming from the bore 9 opening into the
bottom of the guiding groove 1 to the running ?la
ment or ?lamentary bundle, and the liquid thus
transferred to the ?lament or ?lamentary bundle

with liquid comprising a member having a pointed
structure, a longitudinal ?lamentary guideway
through said member terminating substantially
at the point of said member, means for introduc
ing a perforation l3 through the pointed struc

ing groove 1 to the underside M of the pointed
structure l0 in a direction somewhat toward the
point. It has been found that this perforation

guiding groove ‘I to the underside M of the 10 having a liquid diverting surface spaced from
