Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
A winch dyeing machine for the dyeing of a continuous length of fabric in open or rope form comprising a winch, means including retaining side walls defining an arcuate chute having an inlet end open upwardly to receive fabric from the winch and an outlet end open upwardly to discharge the fabric under pull from the winch, spray means for supplying dye liquor into the chute at said inlet end to provide and maintain a body of dye liquor within the chute and so directed as to assist passage of the fabric being dyed along the chute, said spray means being adapted to direct liquor onto opposite sides of the fabric before it enters the chute, means for alternately operating said spray means at opposite sides of the fabric for aiding in pleating the fabric entering the chute, and suction pump means connected to withdraw liquor from said chute at a region adjacent the position where the fabric risEs out of the body of liquor toward said outlet end of the chute.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
108 words
A machine for dyeing fabric in open or rope form comprising means including a winch and a chute for traversing the fabric in pleated formation through the machine, means for supplying dye liquor into the chute, means for extracting liquor from the chute at a level below that at which the liquor is supplied to the machine and returning the liquor to the supply means for recirculation with the pleated fabric through the machine, means for ballooning a tubular fabric after leaving the chute and before passing over the winch and means for traversing the fabric spirally to prevent creasing in the same place on a subsequent passage.
