Abstract
Abstract A method of treating carpet and apparatus for dyeing of carpet is provided wherein a plurality of spray nozzles are disposed in a spray line transverse to the direction of movement of a carpet. Each spray nozzle is connected to a mixing chamber where air and treating liquid, preferably dye, are applied at selected pressures between 0 and 60 p.s.i. Depending on the relative pressure of the air and liquid dye, the mixture is caused to be either atomized or foamed through the spray nozzles onto the face of a moving carpet web. Each nozzle is connected to its own separate mixing chamber the input of which are controlled through a corresponding control valve which turns on and off the spray nozzle by opening and closing a corresponding gas valve and corresponding dye valve. A method and apparatus for solid color dyeing uses a number of reciprocating spray nozzles, each spray nozzle receiving mixed dye and air from a corresponding mixing chamber and spraying the dye, which is foamed or atomized by the air, directly onto a carpet. Separate valves control the dye going into each mixing chamber and are mounted on a fluid control chamber. The field of spray width is adjustable such that different width carpets may be dyed.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
95 words
A method of treating a continuously moving textile web, the steps comprising: (a) conveying the web past at least one treating station; and (b) mixing gas and treating liquid in a plurality of separate mixing chambers disposed at said at least one treating station to create a fine foam spray applied directly onto the web through a plurality of spray nozzles disposed at said at least one treating station and corresponding on a one-to-one basis with said plurality of mixing chambers, each spray nozzle spraying the foam from the corresponding one of said mixing chambers.
Claim 2
Independent Claim
95 words
A method of treating a continuously moving textile web, the steps comprising: (a) conveying the web past at least one treating station; and (b) mixing gas and treating liquid in a plurality of separate mixing chambers disposed at said at least one treating station to create a fine foam spray applied directly onto the web through a plurality of spray nozzles disposed at said at least one treating station and corresponding on a one-to-one basis with said plurality of mixing chambers, each spray nozzle spraying the foam from the corresponding one of said mixing chambers.
Claim 3
Dependent Claim
22 words
The method of claim 1 wherein said foam is sprayed out from said spray nozzle within 21/2 inches of said mixing chamber.
Claim 4
Dependent Claim
25 words
The method of claim 1 further comprising the step of: reciprocating said plurality of spray nozzles while the mixed foam is sprayed onto the web.
Claim 5
Dependent Claim
59 words
The method of claim 1 further comprising the steps of: operatively connecting a plurality of dye valves to a source of dye to cause dye to flow to said plurality of mixing chambers, and wherein there is one dye valve for each mixing chamber, and said connection of said plurality of dye valves to said source is accomplished simultaneously.
Claim 6
Dependent Claim
16 words
The method of claim 4 further including the step of: reciprocating said plurality of mixing chambers.
Claim 7
Dependent Claim
40 words
The method of claim 4 wherein said plurality of spray nozzles are arranged in at least two rows and said reciprocating step includes reciprocating each of said at least two rows out of phase with respect to any other row.
Claim 8
Dependent Claim
31 words
The method of claim 6 further including the step of: reciprocating said plurality of mixing chambers, some mixing chambers reciprocating in phase with each row of said at least two rows.
Claim 9
Dependent Claim
34 words
The method of claim 4 wherein said plurality of spray nozzles are arranged in two rows, and said reciprocating step includes reciprocating each row 180° out of phase with respect to the other row.
Claim 10
Dependent Claim
105 words
Apparatus for treating a continuously moving textile web comprising: (a) a plurality of liquid valves; (b) a plurality of mixing chambers corresponding on a one-to-one basis with said plurality of liquid valves, each mixing chamber having a first input connected to a gas pressure source and a second input connected to the corresponding one of said liquid valves for receiving gas and liquid, respectively, and for mixing gas and liquid to create a foam, (c) a plurality of nozzles for spraying said foam from a corresponding one of said mixing chambers onto a textile web, and (d) reciprocating means for causing said nozzles to reciprocate.
Claim 11
Dependent Claim
105 words
Apparatus for treating a continuously moving textile web comprising: (a) a plurality of liquid valves; (b) a plurality of mixing chambers corresponding on a one-to-one basis with said plurality of liquid valves, each mixing chamber having a first input connected to a gas pressure source and a second input connected to the corresponding one of said liquid valves for receiving gas and liquid, respectively, and for mixing gas and liquid to create a foam, (c) a plurality of nozzles for spraying said foam from a corresponding one of said mixing chambers onto a textile web, and (d) reciprocating means for causing said nozzles to reciprocate.
Claim 12
Dependent Claim
62 words
The apparatus of claim 9 wherein said plurality of liquid valves are fluid pressure controlled valves mounted on an external wall of a control fluid chamber, said external wall having a through opening at the location of corresponding liquid valve, each liquid valve controlled by the pressure of a control fluid in said control fluid chamber just inside of the corresponding opening.
Claim 13
Dependent Claim
40 words
The apparatus of claim 9 further comprising: an internal wall at least partly within said control fluid chamber for isolating a predetermined number of said liquid valves from the control fluid pressure which controls the remainder of said liquid valves.
Claim 14
Dependent Claim
25 words
The apparatus as set forth in claim 11 wherein said predetermined number of liquid valves correspond to and control a predetermined number of said nozzles.
Claim 15
Dependent Claim
26 words
The apparatus of claim 9 wherein said mixing chamber is mounted to said reciprocating means such that said reciprocating means causes said mixing chambers to reciprocate.
Claim 16
Dependent Claim
26 words
The apparatus of claim 9 wherein said reciprocating means includes two reciprocating members, each of said nozzles being mounted to one of said two reciprocating members.
Claim 17
Dependent Claim
70 words
The apparatus of claim 14 further comprising support surface means underlying at least a portion of each of said two reciprocating members for supporting said two reciprocating members above a continuously moving textile web, and upper guide means disposed above at least part of each of said two reciprocating members, and wherein said upper guide means and said support surface means together hold said two reciprocating members against vertical movement.
Claim 18
Dependent Claim
22 words
The apparatus of claim 15 further comprising linear polyethylene bearing portions to bear the relative movements as said two reciprocating members reciprocate.
Claim 19
