Abstract
Abstract An apparatus for impact dyeing a bundle of fibers wherein the fiber bundle is sandwiched between an open belt and an impervious belt and brought into contact with a compartmented porous belt containing a dye, the porous belt contacting the open belt. Impact forces applied through the impervious belt to the porous belt drive the dye from the porous belt through the open belt and into the bundle of fibers.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
An apparatus for impact dyeing a bundle of fibers, comprising: a. an anvil roll, b. a porous belt extending across the anvil roll for carrying a supply of dye, c. an open belt extending across the anvil roll in contact with the porous belt for carrying a bundle of fibers, d. an impervious belt extending across the anvil roll in contact with the fiber bundle and the open belt, and e. means adjacent to the anvil roll for applying impact forces through the impervious belt to the porous belt to drive the dye through the open belt into the fiber bundle.
Claim 2
Independent Claim
101 words
An apparatus for impact dyeing a bundle of fibers, comprising: a. an anvil roll, b. a porous belt extending across the anvil roll for carrying a supply of dye, c. an open belt extending across the anvil roll in contact with the porous belt for carrying a bundle of fibers, d. an impervious belt extending across the anvil roll in contact with the fiber bundle and the open belt, and e. means adjacent to the anvil roll for applying impact forces through the impervious belt to the porous belt to drive the dye through the open belt into the fiber bundle.
Claim 3
Dependent Claim
36 words
The apparatus of claim 1 wherein the porous belt is divided into a plurality of porous dye carrying cells, said cells being separated by impervious partitions to prevent lateral flow of the dye in said belt.
Claim 4
Dependent Claim
21 words
The apparatus of claim 2 wherein the size of the cells is no greater than about one-half inch by one-half inch.
Claim 5
Independent Claim
195 words
An apparatus for impact dyeing a bundle of fibers, comprising: a. an anvil roll, b. a first roll spaced from and parallel to the anvil roll, c. a porous belt extending around the anvil roll and the first roll for carrying a supply of dye, d. a pair of second rolls spaced from and parallel to the anvil roll, e. an open belt extending around the anvil roll and the second rolls for carrying a bundle of fibers, said open belt being in contact with the porous belt at the point where the porous belt is in contact with the anvil roll, f. a plurality of third rolls spaced from and parallel to the anvil roll, g. an impervious belt extending around the third rolls and contacting the open belt and the bundle of fibers at the anvil roll, the third rolls being so positioned that the path of the impervious belt substantially defines a triangle, and h. means positioned adjacent to the anvil roll and within said triangle for applying impact forces to the impervious belt to drive the dye from the porous belt through the open belt and into the bundle of fibers.
Claim 6
Independent Claim
195 words
An apparatus for impact dyeing a bundle of fibers, comprising: a. an anvil roll, b. a first roll spaced from and parallel to the anvil roll, c. a porous belt extending around the anvil roll and the first roll for carrying a supply of dye, d. a pair of second rolls spaced from and parallel to the anvil roll, e. an open belt extending around the anvil roll and the second rolls for carrying a bundle of fibers, said open belt being in contact with the porous belt at the point where the porous belt is in contact with the anvil roll, f. a plurality of third rolls spaced from and parallel to the anvil roll, g. an impervious belt extending around the third rolls and contacting the open belt and the bundle of fibers at the anvil roll, the third rolls being so positioned that the path of the impervious belt substantially defines a triangle, and h. means positioned adjacent to the anvil roll and within said triangle for applying impact forces to the impervious belt to drive the dye from the porous belt through the open belt and into the bundle of fibers.
Claim 7
Dependent Claim
55 words
The apparatus of claim 4 wherein the means for applying impact forces comprises an impact cam mounted for substantially reciprocating motion and having thereon a hammer portion movable into contact with the impervious belt, and eccentric drive means for reciprocating the impact cam to apply impact forces through said impervious belt to said porous belt.
Claim 8
Dependent Claim
36 words
The apparatus of claim 4 wherein the porous belt is divided into individual dye carrying cells, said cells being separated from each other by impervious partitions to prevent lateral flow of the dye in said belt.
Claim 9
Dependent Claim
21 words
The apparatus of claim 6 wherein the size of the cells is no greater than about one-half inch by one-half inch.
Claim 10
Dependent Claim
16 words
The apparatus of claim 6 wherein the cells size is about one-eighth inch by one-eighth inch.
