Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 76 words
A TUFTED OR PILE TEXTILE CONTINUOUS DYEING METHOD INCLUDING CAUSING A LENGTH OF SAID TEXTILE TO TRAVEL CONTINUOUSLY WHILE APPLYING A LIQUID WETTING AGENT AND THEREAFTER A DYEING LIQUID TO ITS PILE; WHEREIN THE IMPROVEMENT COMPRISES PRESSURE SQUEEZING SAID TEXTILE AFTER APPLYING LIQUID WETTING AGENT AND PRIOR TO APPLYING DYEING LIQUID AND UNDER PRESSURE SQUEEZING CONDITIONS SQUEEZING OFF AND DISTRIBUTING SAID AGENT UNIFORMLY IN SAID TEXTILE THROUGHOUT THE LATTER AND INCREASING SAID TEXTILE''S ABSORBING POWER UNIFORMLY.
Claim 2
Dependent Claim 76 words
A TUFTED OR PILE TEXTILE CONTINUOUS DYEING METHOD INCLUDING CAUSING A LENGTH OF SAID TEXTILE TO TRAVEL CONTINUOUSLY WHILE APPLYING A LIQUID WETTING AGENT AND THEREAFTER A DYEING LIQUID TO ITS PILE; WHEREIN THE IMPROVEMENT COMPRISES PRESSURE SQUEEZING SAID TEXTILE AFTER APPLYING LIQUID WETTING AGENT AND PRIOR TO APPLYING DYEING LIQUID AND UNDER PRESSURE SQUEEZING CONDITIONS SQUEEZING OFF AND DISTRIBUTING SAID AGENT UNIFORMLY IN SAID TEXTILE THROUGHOUT THE LATTER AND INCREASING SAID TEXTILE''S ABSORBING POWER UNIFORMLY.
Claim 3
Dependent Claim 27 words
The method of claim 1 in which said wetting agent is applied to said textile by completely immersing said textile in a body of said wetting agent.
Claim 4
Dependent Claim 26 words
The method of claim 1 in which said squeezing is effected by passing said textile between rolling surfaces which do not deflect under the squeezing pressure.
Claim 5
Dependent Claim 30 words
The method of claim 3 in which the pressure exerted by said surfaces on said textile squeezes off said agent substantially as much as is possible by using said surfaces.
Claim 6
Dependent Claim 63 words
The method of claim 1 in which said application of dyeing liquid is effected by causing said textile to travel substantially horizontally with its pile upwardly and said dyeing liquid is poured on said textile''s pile in the form of a uniform continuous dyeing liquid film of uniform quantity and extending transversely for the width of said textile which is to be dyed.
Claim 7
Dependent Claim 23 words
The method of claim 5 in which said quantity is limited substantially to the dyeing liquid absorption of the pile of said textile.
Claim 8
Dependent Claim 26 words
The method of claim 6 in which said squeezing is effected by passing said textile between rolling surfaces which do not deflect under the squeezing pressure.
Claim 9
Dependent Claim 30 words
The method of claim 7 in which the pressure exerted by said surfaces on said textile squeezes off said agent substantially as much as is possible by using said surfaces.
Claim 10
Dependent Claim 27 words
The method of claim 8 in which said wetting agent is applied to said textile by completely immersing said textile in a body of said wetting agent.
Claim 11
Dependent Claim 35 words
The method of claim 6 in which after said application of dyeing liquid the pile of said textile is momentarily pressed backwardly and downwardly without forming a body of liquid in front of this pressing.
