Abstract
Abstract A fluid yarn processing jet of trilaminar construction wherein a recessed discontinuous inner lamina forms a yarn processing duct which has at least one fluid entry port thereto and wherein an outer lamina is readily removable to facilitate the placement of yarn within the duct. All exterior edges in the vicinity of the duct which are resultant from the recessing of the inner laminar are rounded so as to prevent yarn damage.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
67 words
A yarn processing jet of trilaminar construction comprising a yarn duct having at least one fluid entry port thereto, said duct being formed by a discontinuous inner lamina which is recessed from the edges of the outer lamina, the edges forming a portion of the entrance and exit of said duct are radiused in a manner such as to maintain a quadrilateral cross section in said duct.
Claim 2
Dependent Claim
67 words
A yarn processing jet of trilaminar construction comprising a yarn duct having at least one fluid entry port thereto, said duct being formed by a discontinuous inner lamina which is recessed from the edges of the outer lamina, the edges forming a portion of the entrance and exit of said duct are radiused in a manner such as to maintain a quadrilateral cross section in said duct.
Claim 3
Dependent Claim
21 words
The apparatus of claim 1 wherein an outer lamina is readily removable to facilitate the placement of yarn within said duct.
Claim 4
Dependent Claim
18 words
The apparatus of claim 1 wherein said duct has two fluid entry ports disposed on opposite sides thereof.
Claim 5
Dependent Claim
13 words
The apparatus of claim 1 wherein said duct has a substantially rectangular cross-section.
Claim 6
Dependent Claim
15 words
The apparatus of claim 1 wherein said fluid entry port has a substantially rectangular cross-section.
Claim 7
Dependent Claim
14 words
The apparatus of claim 1 wherein said fluid entry port is circular in cross-section.

Claim 11
Dependent Claim
95 words
A yarn processing jet of trilaminar construction comprising a body member having fluid inlet means disposed therein, a yarn duct having a mirror-like finish and having at least one fluid entry port thereto said duct being formed by a recessed discontinuous inner lamina and being connected to said fluid inlet means through said fluid entry port, all yarn exposed edges of the exterior laminae are radiused and all edges forming a portion of the entrance and exit of said duct are radiused in a manner such as to maintain a quadrilateral cross-section in said duct.
Claim 12
Dependent Claim
