Abstract
Abstract This application is directed to a device and method for applying dye to fabric. The device includes an oscillatory wiper blade which channels dye into streams; the falling streams are divided by a moving wire member supported on a circulating band. A portion of the dye may then be distributed onto the teeth of an adjustable comb-like device from which the dye finally drips upon the fabric to form an irregular pattern. The remainder of the dye falls directly onto the fabric, after being subdivided by the circulating band.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
82 words
In a device for the continuous dyeing of a moving textile in which liquid dye streams discharge onto the textile, the improvement comprising means to divide said streams which includes a band member adapted to support webs affixed thereto which are approximately parallel to the direction of movement of said textile, said band member adapted to circulate in an endless loop perpendicular to the direction of movement of said textile, and wherein said webs are positioned to pass through said dye streams.
Claim 2
Dependent Claim
82 words
In a device for the continuous dyeing of a moving textile in which liquid dye streams discharge onto the textile, the improvement comprising means to divide said streams which includes a band member adapted to support webs affixed thereto which are approximately parallel to the direction of movement of said textile, said band member adapted to circulate in an endless loop perpendicular to the direction of movement of said textile, and wherein said webs are positioned to pass through said dye streams.
Claim 3
Dependent Claim
36 words
The device of claim 1 comprising a doctor blade with a series of channels thereon, which lead to the formation of said liquid dye streams and means to impart an oscillatory motion to said doctor blade.
Claim 4
Dependent Claim
21 words
The device of claim 2 wherein the distance between said webs is a fractional integer of the distance between said channels.
Claim 5
Dependent Claim
24 words
The device of claim 1 wherein the plane of said webs is substantially parallel to the plane of said textile positioned below said webs.
Claim 6
Dependent Claim
26 words
The mechanism of claim 1 wherein a comb-like device having teeth is positioned between said web and said textile in the discharge path of said dye.
Claim 7
Dependent Claim
25 words
The device of claim 5 wherein means is provided to adjust the angle of said teeth with respect to the plane of said textile therebelow.
Claim 8
Dependent Claim
17 words
The device of claim 5 wherein the teeth of said comb are rounded in an upward turn.
Claim 9
Dependent Claim
26 words
The device of claim 1 wherein said band member is supported and driven by a pair of rotating rollers positioned on opposite sides of said textile.
Claim 10
Dependent Claim
40 words
The device of claim 1 wherein said band Member comprises two loop members positioned on opposite sides of a plane through said dye streams and said web members are supported at each end thereof by one of said loop members.
