Abstract
Abstract The invention relates to a winch dyeing machine for tubular fabrics in which the fabric is passed through a passageway by the circulation of dye liquor therethrough and on being lifted from the passageway is ballooned by air issuing from a jet or jets, a trigger arm engaged by the fabric operating a valve to control the air jet to regulate the size of the balloon, a roller engaging a metering roller delivering the fabric to the passageway to close the balloon at one end to prevent air from entering the passageway inside the fabric and liquor sprays are directed onto the fabrics as it is lifted from the passageway to close the balloon at the other end.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
201 words
A winch dyeing machine having means for the removal of surplus liquor in the dyeing of tubular fabrics comprising means defining an arcuate passageway upwardly open at opposite ends, a driven metering roller for traversing said fabric through the machine, means comprising controlled jets of dye liquor whereby the fabric leaving said metering rollers is folded in a sinuous manner and directed down into one end of said passageway, means at the other end of said passageway for lifting the fabric from the passageway and directing it toward said metering roller, air jet means effective on the fabric after it has been raised from the passageway and before it passes over said metering roller for ballooning said fabric, a control valve assembly for said jet means, means engaged by the raised fabric connected to said control valve assembly for regulating the size of said ballooning, means for directing jets of said liquor onto the fabric as it is raised out of said passageway to prevent air from the ballooned portion from passing to the fabric in said passageway, and means engaging the fabric at the periphery of said metering roller for preventing air from passing over the roller with the fabric.
Claim 2
Dependent Claim
201 words
A winch dyeing machine having means for the removal of surplus liquor in the dyeing of tubular fabrics comprising means defining an arcuate passageway upwardly open at opposite ends, a driven metering roller for traversing said fabric through the machine, means comprising controlled jets of dye liquor whereby the fabric leaving said metering rollers is folded in a sinuous manner and directed down into one end of said passageway, means at the other end of said passageway for lifting the fabric from the passageway and directing it toward said metering roller, air jet means effective on the fabric after it has been raised from the passageway and before it passes over said metering roller for ballooning said fabric, a control valve assembly for said jet means, means engaged by the raised fabric connected to said control valve assembly for regulating the size of said ballooning, means for directing jets of said liquor onto the fabric as it is raised out of said passageway to prevent air from the ballooned portion from passing to the fabric in said passageway, and means engaging the fabric at the periphery of said metering roller for preventing air from passing over the roller with the fabric.
Claim 3
Dependent Claim
24 words
The machine defined in claim 1, wherein said means engaged by the fabric is a movable trigger arm positioned by said control valve assembly.
Claim 4
Dependent Claim
32 words
The machine defined in claim 2, wherein said control valve assembly comprises a valve spindle connected to said trigger arm and connected to be subject to compressed air at a control pressure.
Claim 5
Dependent Claim
63 words
A winch dyeing machine as in claim 3 in which the valve operating the trigger arm is opened by compressed air supplied to a chamber surrounding the valve spindle at a greater pressure than the pressure in the machine, the ratio between the cross section of an spindle and the orifice in the valve seat being predetermined to maintain the operating force constant.
Claim 6
Dependent Claim
28 words
The machine defined in claim 1, wherein said passage has perforated walls internally of the machine and a pump is provided for circulating dye liquor through said jets.
Claim 7
Dependent Claim
31 words
The machine defined in claim 1, wherein said means at periphery of said metering roller is a spring biased pressure roller engaging the fabric on the periphery of said metering roller.
Claim 8
Dependent Claim
36 words
The machine defined in claim 6, wherein said pressure roller is mounted on a spring biased lever, and means is provided for latching said lever in inoperative position while the machine is being loaded with fabric.
