Abstract
Abstract The method of knitting two-ply segments extending coursewise of a rib fabric on a knitting machine of the type having two sets of needles, for example cylinder and dial needles, a plurality of feeds, and means at a selected feed for guiding the yarn forming each ply into the path of the hooks of the needles on which it is being knit and into the hook-opposite side of the other set of needles. The feeding of the yarns to their respective sets of needles is carried on at a single yarn feed without reliance on any special cams or delayed timing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
241 words
A method of knitting a two-ply segment of a fabric wherein each ply of said fabric is independent of the other ply on a rib gated knitting machine of the dial and cylinder type having dial needles and cylinder needles and at least a yarn feed station For each two-ply segment of fabric, said method comprising: a. guiding the yarn to form one of said plies into knitting position on the hook-side of the shanks of certain of said cylinder needles at said yarn feed station, at least two of said certain cylinder needles being immediately adjacent one another, and said yarn extending on the hook-opposite side of the shanks of said dial needles, said yarn being fed into knitting position along a path which defines an angle exceeding the tangent to the cylinder formed by the cylinder needles taken at the point where the yarn is first engaged by the cylinder needles; b. simultaneously guiding a second yarn to form the other ply in said two-ply segment into knitting position on the hook-side of the shanks of certain of said dial needles at least two of said certain dial needles being immediately adjacent one another, and said yarn extending on the hook-opposite side of the shanks of said cylinder needles; and c. synchronously moving said certain dial and cylinder needles at said yarn feed station into knitting position to form both plies of said two-ply segment at the same feed.
Claim 2
Independent Claim
241 words
A method of knitting a two-ply segment of a fabric wherein each ply of said fabric is independent of the other ply on a rib gated knitting machine of the dial and cylinder type having dial needles and cylinder needles and at least a yarn feed station For each two-ply segment of fabric, said method comprising: a. guiding the yarn to form one of said plies into knitting position on the hook-side of the shanks of certain of said cylinder needles at said yarn feed station, at least two of said certain cylinder needles being immediately adjacent one another, and said yarn extending on the hook-opposite side of the shanks of said dial needles, said yarn being fed into knitting position along a path which defines an angle exceeding the tangent to the cylinder formed by the cylinder needles taken at the point where the yarn is first engaged by the cylinder needles; b. simultaneously guiding a second yarn to form the other ply in said two-ply segment into knitting position on the hook-side of the shanks of certain of said dial needles at least two of said certain dial needles being immediately adjacent one another, and said yarn extending on the hook-opposite side of the shanks of said cylinder needles; and c. synchronously moving said certain dial and cylinder needles at said yarn feed station into knitting position to form both plies of said two-ply segment at the same feed.
Claim 3
Independent Claim
189 words
A method of knitting a two-ply segment of a fabric, wherein each ply of said fabric is independent of the other ply, on a rib gated knitting machine of the type having dial needles and cylinder needles and also having a yarn feed station, said method comprising the steps of: a. guiding a first yarn for one of said plies into knitting position on the hook-side of the shanks of all said cylinder needles, but on the hook-opposite side of the shanks of said dial needles, said first yarn being fed into knitting position along a path which defines an angle exceeding the tangent to the cylinder formed by the cylinder needles taken at the point where the yarn is first engaged by the cylinder needles; b. simultaneously guiding a second yarn for the other ply into knitting position on the hook-side of the shanks of all of said dial needles, but on the hook-opposite side of the shanks of said cylinder needles; and c. synchronously operating all of said dial and cylinder needles into knitting position to form both plies of said two-ply segment at the same feed.
Claim 4
Independent Claim
189 words
A method of knitting a two-ply segment of a fabric, wherein each ply of said fabric is independent of the other ply, on a rib gated knitting machine of the type having dial needles and cylinder needles and also having a yarn feed station, said method comprising the steps of: a. guiding a first yarn for one of said plies into knitting position on the hook-side of the shanks of all said cylinder needles, but on the hook-opposite side of the shanks of said dial needles, said first yarn being fed into knitting position along a path which defines an angle exceeding the tangent to the cylinder formed by the cylinder needles taken at the point where the yarn is first engaged by the cylinder needles; b. simultaneously guiding a second yarn for the other ply into knitting position on the hook-side of the shanks of all of said dial needles, but on the hook-opposite side of the shanks of said cylinder needles; and c. synchronously operating all of said dial and cylinder needles into knitting position to form both plies of said two-ply segment at the same feed.
Claim 5
Dependent Claim
174 words
In a knitting machine of the type having dial needles and cylinder needles arranged in rib gated relationship and operated synchronously, a yarn guide means positioned in operative relationship with a yarn feed of the knitting machine, said guide means including a first opening therein for receiving a first yarn from a supply source and directing said first yarn into knitting position on the hook-side of the shanks of all dial needles, but on the hook-opposite side of the shanks of the cylinder needles, said guide means also including a second opening therein for simultaneously receiving a second yarn from a supply source and directing said second yarn into knitting position on the hook-side of the shanks of all the cylinder needles, but on the hook-opposite side of the shanks of said dial needles, the yarn from said second opening being fed along a path which defines an angle exceeding the tangent to the cylinder formed by the cylinder needles taken at the point where the yarn is first engaged by the cylinder needles.
Claim 6
Dependent Claim
174 words
In a knitting machine of the type having dial needles and cylinder needles arranged in rib gated relationship and operated synchronously, a yarn guide means positioned in operative relationship with a yarn feed of the knitting machine, said guide means including a first opening therein for receiving a first yarn from a supply source and directing said first yarn into knitting position on the hook-side of the shanks of all dial needles, but on the hook-opposite side of the shanks of the cylinder needles, said guide means also including a second opening therein for simultaneously receiving a second yarn from a supply source and directing said second yarn into knitting position on the hook-side of the shanks of all the cylinder needles, but on the hook-opposite side of the shanks of said dial needles, the yarn from said second opening being fed along a path which defines an angle exceeding the tangent to the cylinder formed by the cylinder needles taken at the point where the yarn is first engaged by the cylinder needles.
Claim 7
Dependent Claim
92 words
The improvement according to claim 3, wherein said guide means comprises a plate having said first and second openings therein, said plate being attached to a portion of said machine and being disposed in a vertical plane, said first opening in the plates positioned at a point below the horizontal plane defined by the dial needles and on the hook-side of said cylinder needle shanks, said second opening being inwardly disposed in a radial direction from the cylinder formed by the cylinder needles and on the hook-side of said dial needle shanks.
Claim 8
Dependent Claim
71 words
The improvement according to claim 4, wherein said first opening is radially spaced from said cylinder needles and circumferentially spaced from a prescribed point on the cylinder where said first yarn is initially engaged by the cylinder needles, said radial and circumferential spacing being such that said first yarn is fed to said point at an angle exceeding a tangent to the cylinder formed by said cylinder needles at said point.
