Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
141 words
Apparatus for applying a liquid finishing agent to a textile thread or yarn, comprising valved liquid finishing agent supply means, a finishing agent supply nozzle connected thereto to discharge liquid finishing agent downwardly as a free-falling jet; a suction nozzle positioned below said agent discharge nozzle and having a suction orifice coaxially in register with the discharge orifice of said finishing agent supply nozzle, said nozzles having substantially circular cross-sections, the inside diameter of said suction nozzle being substantially equal to the inside diameter of said supply nozzle; and a fiber guide at said suction orifice to maintain a moving thread or yarn in contact with said suction orifice; the distance between the discharge orifice of said agent discharge nozzle and the suction orifice of said suction nozzle being about 1/2 to 20 times the inside diameter of said suction orifice.
