Abstract
Abstract Deep heating of the pile of a pile fabric is accomplished rapidly by an electrifier roll and the heated pile fibers are acted upon by a downwardly weighted embossing or texturing roll or bar having temperature approximating that of the pile fibers. The position of the patterning roll or bar is adjustable, and control is exercised over both axial and rotational movements thereof to enable the production of different pattern effects.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
151 words
A method of treating pile fabric comprising: advancing the pile fabric along a path extending sequentially through a heating zone, a texturing zone and a cooling zone, mechanically contacting in said heating zone the pile face of the advancing fabric with relatively moving heating means having at least one heated edge portion which moves along the pile fibers to heat the fibers along substantial portions of their lengths to a temperature level at which they can accept a permanent set, mechanically reorienting the pile fibers relative to the backing of said fabric as the advancing fabric moves through said texturing zone and while said pile fibers are in the heated condition imparted to them by said heating means, said reorienting being carried out without imposing deleterious temperature changes upon said pile fibers, and allowing said pile fibers to cool in said cooling zone to set the fibers in their reoriented conditions.
Claim 2
Independent Claim
151 words
A method of treating pile fabric comprising: advancing the pile fabric along a path extending sequentially through a heating zone, a texturing zone and a cooling zone, mechanically contacting in said heating zone the pile face of the advancing fabric with relatively moving heating means having at least one heated edge portion which moves along the pile fibers to heat the fibers along substantial portions of their lengths to a temperature level at which they can accept a permanent set, mechanically reorienting the pile fibers relative to the backing of said fabric as the advancing fabric moves through said texturing zone and while said pile fibers are in the heated condition imparted to them by said heating means, said reorienting being carried out without imposing deleterious temperature changes upon said pile fibers, and allowing said pile fibers to cool in said cooling zone to set the fibers in their reoriented conditions.
Claim 3
Dependent Claim
29 words
A method according to claim 1 wherein said step of mechanically reorienting the heated pile fibers is carried out in the absence of material temperature changes in said fibers.
Claim 4
Dependent Claim
34 words

Claim 5
Dependent Claim
14 words
A method according to claim 3 wherein said heat-insulating surface bears a relief pattern.
Claim 6
Dependent Claim
53 words
A method according to claim 1 wherein said step of mechanically reorienting the heated pile fibers is carried out by advancing the pile fibers relative to the surface of a member pressed against the pile face to cause said fibers to catch and bunch together and produce localized density variations in the pile.
Claim 7
Independent Claim
183 words
A method of treating pile fabric comprising: advancing the pile fabric along a path extending sequentially through a heating zone, a texturing zone and a cooling zone, contacting in said heating zone the pile face of the advancing fabric with a relatively moving heating medium which moves the pile fibers of said fabric relative to each other to expose said fibers to contact with the heating medium along substantial portions of their lengths, mechanically reorienting the heated pile fibers relative to the backing of said fabric as the advancing fabric moves through said texturing zone, and allowing said pile fibers to cool in saiD cooling zone to set the fibers in their reoriented conditions; said contacting step being an electrifying step in which the pile is brushed and combed mechanically and in which heated metal edges move along the pile fibers to polish and heat the fibers to a temperature level at which they can accept a permanent set, and said mechanical reorienting occurring while the pile fibers are in this heated condition and without imposing deleterious temperature changes upon the pile fibers.
Claim 8
Independent Claim
183 words

Claim 9
Dependent Claim
78 words
A method according to claim 6 wherein said electrifying step is carried out to impart a forwardly directed lay to the pile of the advancing fabric, and wherein said step of mechanically reorienting the heated pile fibers is carried out by advancing the pile fibers beneath a downwardly weighted member having an edge against which the forwardly directed pile fibers may catch in a random fashion to produce randomly sized and shaped localized density variations in the pile.
