Abstract
Abstract A method for continuously scouring and blooming an advancing pile carpet includes first wetting the pile side of the carpet with 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: 6
Claim 1
Independent Claim
126 words
A METHOD OF SCOURING AND BLOOMING A PILE CARPET COMPRISING: ADVANCING A WETTED CARPET INTO AND THROUGH A FIRST TANK AT LEAST PARTIALLY FILLED WITH HOT WATER AND IMMERSING SAID CARPET IN THE WATER; DIRECTING HIGH PRESSURE SPRAY OF HOT WATER AT A PRESSURE OF AT LEAST 100 P.S.I.G. AT A DOWNWARD ANGLE AT THE PILE SIDE OF SAID CARPET AS IT EMERGES FROM THE WATER IN SAID FIRST TANK; ADVANCING SAID CARPET INTO AND THROUGH A SECOND TANK AT LEAST PARTIALLY FILLED WITH HOT WATER AND IMMERSING SAID CARPET IN THE WATER; DIRECTING A RINSING SPRAY AT SAID PILE SIDE OF SAID CARPET AS IT EMERGES FROM THE WATER IN SAID SECOND TANK; AND SUPPLYING SAID HIGH PRESSURE SPRAY WITH WATER FROM SAID SECOND TANK.
Claim 2
Independent Claim
126 words
A METHOD OF SCOURING AND BLOOMING A PILE CARPET COMPRISING: ADVANCING A WETTED CARPET INTO AND THROUGH A FIRST TANK AT LEAST PARTIALLY FILLED WITH HOT WATER AND IMMERSING SAID CARPET IN THE WATER; DIRECTING HIGH PRESSURE SPRAY OF HOT WATER AT A PRESSURE OF AT LEAST 100 P.S.I.G. AT A DOWNWARD ANGLE AT THE PILE SIDE OF SAID CARPET AS IT EMERGES FROM THE WATER IN SAID FIRST TANK; ADVANCING SAID CARPET INTO AND THROUGH A SECOND TANK AT LEAST PARTIALLY FILLED WITH HOT WATER AND IMMERSING SAID CARPET IN THE WATER; DIRECTING A RINSING SPRAY AT SAID PILE SIDE OF SAID CARPET AS IT EMERGES FROM THE WATER IN SAID SECOND TANK; AND SUPPLYING SAID HIGH PRESSURE SPRAY WITH WATER FROM SAID SECOND TANK.
Claim 3
Independent Claim
143 words
A method of scouring and blooming a pile carpet comprising: continuously advancing the pile carpet; spraying the pile side of said carpet with a first hot water spray to uniformly wet the pile of said carpet; immersing said advancing carpet in a first tank of hot water to loosen the finish on said pile; directing a high pressure spray at a downward angle at the pile side of said carpet as it emerges from the water in said first tank to remove the finish and initiate blooming; immersing said advancing carpet in a second tank containing hot water; spraying the pile side of said carpet as it emerges from the water in said second tank to wash away any residual finish and to provide the final blooming of the pile; and pumping water from said second tank to supply said high pressure spray.
Claim 4
Independent Claim
143 words
A method of scouring and blooming a pile carpet comprising: continuously advancing the pile carpet; spraying the pile side of said carpet with a first hot water spray to uniformly wet the pile of said carpet; immersing said advancing carpet in a first tank of hot water to loosen the finish on said pile; directing a high pressure spray at a downward angle at the pile side of said carpet as it emerges from the water in said first tank to remove the finish and initiate blooming; immersing said advancing carpet in a second tank containing hot water; spraying the pile side of said carpet as it emerges from the water in said second tank to wash away any residual finish and to provide the final blooming of the pile; and pumping water from said second tank to supply said high pressure spray.
Claim 5
Dependent Claim
50 words
A method of scouring and blooming a pile carpet as set forth in claim 1 including: draining water from said first tank to maintain a substantially constant level and continuously remove the finish therein; and providing a path for water to flow from said first tank into said second tank.
Claim 6
Dependent Claim
42 words
A method of scouring and blooming a pile carpet as set forth in claim 3 including supporting the carpet transversely across the width thereof as it advances past said high pressure spray to insure uniform impact of the spray on said carpet.
