Abstract
Abstract Apparatus for continuously scouring and blooming an advancing pile carpet includes facilities for first wetting the pile side of the carpet with a hot water spray, and then immersing the carpet in a first tank containing hot water. The carpet is then advanced past a high pressure spray positioned above the first tank which directs a high impact spray at the pile to remove the finish on the pile and provide the initial blooming or bulk development of the yarn. The carpet then passes through a second tank containing hot water and past a final spray which rinses away any residual finish and provides the final blooming. Water to supply the high pressure spray is pumped from the second tank. The first and second tanks are interconnected so that water can flow from the first tank into the second tank to supply the pump. Facilities are also provided to remove the finish from the water in the first tank.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
142 words
Apparatus for scouring and blooming a pile carpet comprising: a first and second tank, each at least partially filled with water, said first and second tanks being interconnected to provide water flow therebetween; means for advancing the carpet through said first tank and then through said second tank; first spray means positioned above said first tank for spraying the pile side of said advancing carpet with hot water prior to entering the water in said first tank; second spray means positioned above said first tank for spraying said pile side of said carpet with hot water under high pressure as it exits from the water in said first tank; third spray means for spraying said pile side of said carpet as it exits from said second tank; and means for pumping water from said second tank to supply said second spray means.
Claim 2
Dependent Claim
142 words
Apparatus for scouring and blooming a pile carpet comprising: a first and second tank, each at least partially filled with water, said first and second tanks being interconnected to provide water flow therebetween; means for advancing the carpet through said first tank and then through said second tank; first spray means positioned above said first tank for spraying the pile side of said advancing carpet with hot water prior to entering the water in said first tank; second spray means positioned above said first tank for spraying said pile side of said carpet with hot water under high pressure as it exits from the water in said first tank; third spray means for spraying said pile side of said carpet as it exits from said second tank; and means for pumping water from said second tank to supply said second spray means.
Claim 3
Dependent Claim
38 words
Apparatus for scouring and blooming a pile carpet as set forth in claim 1 including means for controlling the flow of water from said first tank to said second tank to provide an adequate supply for said pump.
Claim 4
Dependent Claim
29 words
Apparatus for scouring and blooming a pile carpet as set forth in claim 1 wherein the pressure of said second high pressure spray means is at least 100 p.s.i.g.
Claim 5
Dependent Claim
39 words
Apparatus for scouring and blooming a pile carpet as set forth in claim 3 wherein said high pressure spray is directed at a predetermined angle to said carpet in a direction opposite to the path of said advancing carpet.
Claim 6
Dependent Claim
34 words
Apparatus for scouring and blooming a pile carpet as set forth in claim 4 wherein said predetermined angle is at least 15* as measured from a line perpendicular to said path of said carpet.
Claim 7
Dependent Claim
49 words
Apparatus for scouring and blooming a pile carpet as set forth in claim 5 including means positioned substantially opposite to said second high pressure spray means for supporting said carpet a predetermined distance from said second spray means to provide uniform impact of the spray transversely across said carpet.
Claim 8
Dependent Claim
220 words
Apparatus for scouring and blooming a pile carpet comprising: a first and a second tank each adapted to be at least partially filled with water, said tanks being interconnected to provide water flow therebetween; means for continuously advancing a carpet first into and out of said first tank, and then into and out of said second tank; first spray means positioned above said first tank for uniformly spraying the pile side of said carpet prior to entering the water in said first tank; second spray means positioned above said first tank for uniformly directing a high pressure spray at the pile side of said carpet after leaving the water in said first tank to remove the finish on said pile and initiate blooming thereof; means for maintaining a substantially constant level of water in said first tank and draining excess water and removed finish therefrom; third spray means positioned above said second tank for uniformlY spraying the pile side of said carpet after leaving the water in said second tank; means for heating the water in said first and second tanks; means for pumping water from said second tank to supply said second spray means; and means for controlling the flow of water from said first tank to said second tank to provide an adequate supply for said pumping means.
Claim 9
Dependent Claim
220 words
Apparatus for scouring and blooming a pile carpet comprising: a first and a second tank each adapted to be at least partially filled with water, said tanks being interconnected to provide water flow therebetween; means for continuously advancing a carpet first into and out of said first tank, and then into and out of said second tank; first spray means positioned above said first tank for uniformly spraying the pile side of said carpet prior to entering the water in said first tank; second spray means positioned above said first tank for uniformly directing a high pressure spray at the pile side of said carpet after leaving the water in said first tank to remove the finish on said pile and initiate blooming thereof; means for maintaining a substantially constant level of water in said first tank and draining excess water and removed finish therefrom; third spray means positioned above said second tank for uniformlY spraying the pile side of said carpet after leaving the water in said second tank; means for heating the water in said first and second tanks; means for pumping water from said second tank to supply said second spray means; and means for controlling the flow of water from said first tank to said second tank to provide an adequate supply for said pumping means.
Claim 10
Dependent Claim
36 words
Apparatus for scouring and blooming a pile carpet as set forth in claim 7 wherein said second spray has a pressure of at least 100 p.s.i.g. and is directed at an angle against the advancing carpet.
