Abstract
Abstract Apparatus for producing and collecting continuous glass filaments is provided comprising: feeder means for supplying a plurality of streams of molten glass to be drawn into filaments; means for applying a liquid to said filaments; a rotatable member adapted to wind said filaments in layers therearound and to draw said streams into said filaments; distribution means for supplying a plurality of streams of gas to at least partially dry the filaments wound around said member, said streams being directed into contact with the layers along the length thereof and over a portion of the arcuate periphery of the layers; and collection means for removing the moisture containing air from around the periphery of said layers of filaments, said collection means extending along the length of said layers and over a portion of the arcuate periphery of the layers.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
180 words
Apparatus for producing and collecting continuous glass filaments comprising: feeder means for supplying a plurality of streams of molten glass to be drawn into filaments; means for applying a coating to said filaments; a rotatable member adapted to wind said filaments in layers therearound and to draw said streams into said filaments; a plurality of spaced apart fingers having an orifice therein to direct a body of gas as a plurality of streams to at least partially dry the coated filaments wound around said member, said gas being directed into contact with the layers along the length thereof and over a portion of the arcuate periphery of the layers; and collection means for removing the vapor containing air from around the periphery of said layers of filaments, said collection means being comprised of a housing having an arcuate, foraminous inner surface positioned adjacent said fingers, the orifices of said fingers being located between said layers and said foraminous surface, said foraminous surface extending along the length of said layers and over a portion of the arcuate periphery of the layers.
Claim 2
Dependent Claim
180 words
Apparatus for producing and collecting continuous glass filaments comprising: feeder means for supplying a plurality of streams of molten glass to be drawn into filaments; means for applying a coating to said filaments; a rotatable member adapted to wind said filaments in layers therearound and to draw said streams into said filaments; a plurality of spaced apart fingers having an orifice therein to direct a body of gas as a plurality of streams to at least partially dry the coated filaments wound around said member, said gas being directed into contact with the layers along the length thereof and over a portion of the arcuate periphery of the layers; and collection means for removing the vapor containing air from around the periphery of said layers of filaments, said collection means being comprised of a housing having an arcuate, foraminous inner surface positioned adjacent said fingers, the orifices of said fingers being located between said layers and said foraminous surface, said foraminous surface extending along the length of said layers and over a portion of the arcuate periphery of the layers.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1 wherein said fingers and said collection means extend around a majority of the arcuate periphery of the layers.
Claim 4
Dependent Claim
23 words
The apparatus of claim 4 wherein said fingers and collection means are movable with respect to the axis of rotation of said member.
Claim 5
Dependent Claim
38 words
The apparatus of claim 1 further comprising a flexible baffle extending from an end of said collection means toward said member to assist in confining the vapor containing air to a zone between the layers and the housing.
Claim 6
Dependent Claim
18 words
The apparatus of claim 1 further comprising means for heating the gas to be supplied by said fingers.
Claim 7
Dependent Claim
36 words
The apparatus of claim 1 wherein said fingers and said collection means are positioned such that the gas supplied by the fingers contacts the layers and then passes between said fingers and through said foraminous surface.
