Abstract
Abstract This invention relates to a method and apparatus for forming glass filament in which a fluid is applied to the filament which is passed in contact with a suction means to contact the filament with air to remove the fluid from the filament and subsequently applying a sizing composition to the filament.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
Apparatus for applying a coating to a filament having a liquid on the surface thereof comprising: (a) a walled member, the wall of said member having an aperture communicating through the wall of said member; (b) a liquid-absorbing material, adapted for contact with said filament, and positioned in contact with said aperture; and, (c) means providing a suction to the interior of said walled member to aid in removal of said liquid from from said filament, (d) means for applying a coating to said filament upon disengagement from said contact with said liquid-absorbing material.
Claim 2
Dependent Claim
94 words
Apparatus for applying a coating to a filament having a liquid on the surface thereof comprising: (a) a walled member, the wall of said member having an aperture communicating through the wall of said member; (b) a liquid-absorbing material, adapted for contact with said filament, and positioned in contact with said aperture; and, (c) means providing a suction to the interior of said walled member to aid in removal of said liquid from from said filament, (d) means for applying a coating to said filament upon disengagement from said contact with said liquid-absorbing material.
Claim 3
Dependent Claim
13 words
The apparatus of claim 1 in which said aperture comprises an elongated slot.
Claim 4
Dependent Claim
18 words
The apparatus of claim 1 in which walls of said slot diverge from the centerline of said slot.
Claim 5
Dependent Claim
32 words
The apparatus of claim 3 in which one of the walls of said slot projects outwardly a distance greater than the outward projection of the other of the walls of said slot.
Claim 6
Independent Claim
66 words
A method of applying a size composition to a glass filament having a quenching fluid on the surface thereof which comprises: (a) passing said glass filament into contact with suction means; (b) drawing air into contact with said glass filament; (c) withdrawing said quenching fluid from the surface of said glass filament into said suction means; and (d) applying a size composition to said glass filament.
Claim 7
Independent Claim
66 words
A method of applying a size composition to a glass filament having a quenching fluid on the surface thereof which comprises: (a) passing said glass filament into contact with suction means; (b) drawing air into contact with said glass filament; (c) withdrawing said quenching fluid from the surface of said glass filament into said suction means; and (d) applying a size composition to said glass filament.
Claim 8
Dependent Claim
21 words
The method of claim 5 in which said filament is passed into contact with liquid-absorption means superimposed on said suction means.
