Abstract
Abstract A binder applicator for applying liquid binder to textile fibers is described which involves a roller having a slightly concave surface from end to end. The roller is provided at each end with a rim to direct binder towards the center of the roller surface. The applicator housing is provided with an inlet to direct binder into the housing and an outlet for the removal of binder, the outlet means being adjustable in height inside the applicator housing to maintain a liquid depth in the housing sufficient to insure that the roller passes through the liquid during rotation to maintain binder on the surface of the roller.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
154 words
A roller applicator for applying solution to fibers drawn across the surface thereof comprising a housing, a freely rotatable cylindrical applicator contained in said housing, said housing being provided with a port through which the roller is exposed to the atmosphere and out of which a portion of the surface of the applicator protrudes; means to feed the solution across the surface of the roller inside of said housing; means to remove excess solution from the housing continuously; means associated with the applicator surface to direct flow of solution on the surface of said roller towards the center thereof and away from the ends thereof, said means including a concave applicator surface and collar means on each end of said applicator, said collars having diameters greater than the diameter of any portion of the applicator located therebetween, to thereby direct fluid from said collar towards the center of said applicator along said concave surface.
Claim 2
Dependent Claim
154 words
A roller applicator for applying solution to fibers drawn across the surface thereof comprising a housing, a freely rotatable cylindrical applicator contained in said housing, said housing being provided with a port through which the roller is exposed to the atmosphere and out of which a portion of the surface of the applicator protrudes; means to feed the solution across the surface of the roller inside of said housing; means to remove excess solution from the housing continuously; means associated with the applicator surface to direct flow of solution on the surface of said roller towards the center thereof and away from the ends thereof, said means including a concave applicator surface and collar means on each end of said applicator, said collars having diameters greater than the diameter of any portion of the applicator located therebetween, to thereby direct fluid from said collar towards the center of said applicator along said concave surface.
Claim 3
Dependent Claim
48 words
The apparatus of claim 1 wherein baffle means are provided across the width of the applicator and adjacent its surface to provide a blanket of fluid on the surface continuously when the roller is rotating and fluid is being fed to the baffle surface on a continuous basis.
Claim 4
Dependent Claim
61 words
The apparatus of claim 1 wherein fluid fed to the housing is contacted with a baffle directing the fluid away from the surface of the roller applicator and wherein fluid level control means in the housing is at a level such that the roller applicator is at least partially in contact with solution in the housing at all times during operation.
Claim 5
Dependent Claim
121 words
An applicator system for applying solution to fibers passed in contact with the surface thereof comprising a housing, fluid inlet means communicating with the interior of said housing, a cylindrical roller applicator positioned in said housing and freely rotatable therein, adjustable liquid level control means in said housing to limit the depth of fluid contained therein, means on the surface of said roller applicator including a concave applicator surface and a collar on each end of said applicator, said collars being greater in diameter than the diameter of any portion of the applicator located therebetween to thereby direct fluid contacted with the surface of said applicator towards the central portion of said surface of the applicator and away from the collars.
Claim 6
Dependent Claim
121 words
An applicator system for applying solution to fibers passed in contact with the surface thereof comprising a housing, fluid inlet means communicating with the interior of said housing, a cylindrical roller applicator positioned in said housing and freely rotatable therein, adjustable liquid level control means in said housing to limit the depth of fluid contained therein, means on the surface of said roller applicator including a concave applicator surface and a collar on each end of said applicator, said collars being greater in diameter than the diameter of any portion of the applicator located therebetween to thereby direct fluid contacted with the surface of said applicator towards the central portion of said surface of the applicator and away from the collars.
