Abstract
Abstract A method and apparatus to automatically adjust baffle setting for variations in processing conditions when using a yarn treating fluid jet having a baffle adjacent its outlet end. The baffle is mounted for free movement toward and away from the outlet end of the jet and defines with the adjacent outlet end surface of the jet a mutually shared area greater than the crosssectional area of the exit of the treatment channel of the jet. The baffle is mounted at a position of equilibrium with respect to the fluid flow rate from the jet and can automatically adjust for minor changes in flow rate to maintain uniform operability.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
82 words
In a yarn treating apparatus including a jet having inlet and outlet ends connected by a passage through which yarn together with fluid passes for treatment, the improvement comprising: a baffle mounted adjacent to said outlet end for free movement toward and away from said outlet end, said baffle having a surface facing said outlet end, said baffle surface defining with said outlet end a mutually shared area greater in area than the cross-sectional area of the passage at said outlet end.
Claim 2
Dependent Claim
82 words
In a yarn treating apparatus including a jet having inlet and outlet ends connected by a passage through which yarn together with fluid passes for treatment, the improvement comprising: a baffle mounted adjacent to said outlet end for free movement toward and away from said outlet end, said baffle having a surface facing said outlet end, said baffle surface defining with said outlet end a mutually shared area greater in area than the cross-sectional area of the passage at said outlet end.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1, said baffle being spaced from said passage at said outlet end.
Claim 4
Dependent Claim
22 words
The apparatus as defined in claim 2, said baffle being pivotally mounted for swinging movement toward and away from said outlet end.
Claim 5
Dependent Claim
23 words
The apparatus as defined in claim 1, including means for limiting the travel of the baffle toward the outlet end of the jet.
Claim 6
Dependent Claim
82 words
In a method for operating a yarn treating jet that includes passing yarn together with high velocity fluid through the jet passage from its inlet to its outlet end at a fixed rate and impinging the yarn and fluid against a baffle located near the outlet end of the jet the improvement comprising: mounting said baffle for free movement toward and away from the outlet end of the jet at a location of equilibrium for the baffle at said fixed flow rate.
Claim 7
Dependent Claim
82 words
In a method for operating a yarn treating jet that includes passing yarn together with high velocity fluid through the jet passage from its inlet to its outlet end at a fixed rate and impinging the yarn and fluid against a baffle located near the outlet end of the jet the improvement comprising: mounting said baffle for free movement toward and away from the outlet end of the jet at a location of equilibrium for the baffle at said fixed flow rate.
