  IMPROVEMENTS TO KNITTING METHODS ON CIRCULAR KNITTING MACHINES WITH INDEPENDENT NEEDLE.

  
 <EMI ID = 1.1>

  
dimensioning on circular knitting machines with independent needles.

  
The invention relates to the forming, in the manufacture by a circular type knitting machine with independent needles, of fabric

  
 <EMI ID = 2.1>

  
of such a design is the well-known enhanced or overloaded stripe in blue-red hosiery

  
In accordance with the present invention, there is provided a method of knitting on an independent needle circular knitting machine having two stitch cams (e.g. a stitch cam having and a back stitch cam on a cam block), which consists of: in selecting one or more needles and knitting with this or these selected needles only, using one of said stitch cams, and with other needles only using the other of said stitch cams, in a single passage of said needles in front of said cams; and subsequently select one or more different needles

  
needle or needles selected first, and knitting with said different needle or needles selected only,

  
using one of said painted cams in a subsequent passage of the needles in front of said cams.

  
 <EMI ID = 3.1>

  
first "when used above and in the appended claims, is to be understood as comprising a group of needles which, on the whole, is different from the group selected first, and does not exclude a case in which one or several needles are or are common to two different groups.

  
The first of said needles can be caused to knit a yarn by the first stitch cam so as to form a pattern in a fabric knitted by said other needles of another yarn by

  
said second stitch cam during said only one passage of the needles in front of the cams. After said one pass of said needles in front of said cams, the direction of knitting can be reversed so that the needles make another pass in front of said cams in the opposite direction; during said other pass a third thread is knitted by a few needles under the second mentioned stitch cam (for example the rear cam) so as to form a pattern on the fabric knitted by other needles at the first mentioned stitch cam ( for example the front cam) during the said other passage.

  
Further, according to the invention, there is provided a method

  
 <EMI ID = 4.1>

  
tes, a line of fabric in which one yarn and another yarn form separate loops with the other yarn floating across the loops of said one yarn, which includes selecting needles for knitting said one yarn,

  
lifting these needles to release their latches and picking up the yarn, lowering these needles below the level of the remaining needles which knit said other yarn, and to a depth sufficient to knit, and retaining said selected needles below the level of said remaining needles, while said remaining needles take said other thread, thereby forcing said other thread to be floated across the stripes in which said one thread has been knitted

  
 <EMI ID = 5.1>

  
Still further, according to the invention, there is provided a method for knitting on a circular knitting machine with independent needles, a pattern formed of one yarn and another yarn in a fabric.

  
of a third yarn, which consists in knitting in a row one or more loops of the said one yarn following the said drawing, -and in the same line, and during the same stroke of the machine, in knitting loops of the said third yarn and floating said third yarn through the stripes in which said loops of said one yarn have been knitted, then reversing the direction of knitting to knit the next row, knitting loops of said other yarn in said next row by according to said design, and in the same reverse stroke of the machine, knitting loops of said third yarn and floating said third yarn through the stripes in which said loops of said other yarn have been knitted-

  
Further, in accordance with the present invention, there is provided a single-station knitting method comprising a forward stitch cam and a reverse stitch cam, on an independent needle circular knitting machine, a fabric having a body. knitted from one yarn and a design knitted using a second yarn and in which the said one yarn is floated behind the loops of the said second yarn, which consists in reciprocating the needles that knit the said a yarn and the needles which knit said second yarn at said knitting station, to draw loops of said yarn under one of said cams and

  
in drawing loops of said second thread under the other of said cams.

  
In a method as defined in any one of the preceding paragraphs, some needles may be made to pass under a stitch cam to knit loops of a yarn and other needles may be made to pass over said stitch cam. to release their latches from the other wire.

  
Further, according to the invention, there is provided in or for a circular knitting machine with independent needles, a needle cylinder, a plurality of needles mounted in said cylinder, a knitting station having a stitch cam forward and a back stitch cam near said cylinder, means for selectively raising individual needles from said needles to release their latches and take up thread, and means for selectively lowering said individual needles and causing them to pass under the needle. said cam before stitches and consequently to pull loops of thread.

  
Further, in accordance with the invention, there is provided in and for a circular knitting machine, with independent needles, a needle cylinder, a plurality of needles in said cylinder, means for selectively moving individual needles of the needle. said needles from a common level to release their latches and take a drawing thread, means for returning said selected needles to said common level, and means for further selectively moving said needles which have taken up thread. drawing and get them to knit said drawing yarn.

  
A method and apparatus in accordance with the invention for producing a fabric comprising such a design enhanced with an overlaid pattern is described below by way of example with reference to the accompanying drawing in which:
Figo 1 is a schematic view of a tissue produced by a method and mechanism according to the invention; and, Figo 2 is a schematic representation of a cam path for needles and rods.

  
 <EMI ID = 6.1>

  
colored elements, B, Y, G and R, indicated by the strong black lines in the figure. The lighter lines intersecting the different diamonds represent ornamental threads or overlaid with one or more colors different from the color of the diamonds they intersect. A large number of color combinations can be used, the knitting method according to the invention offering wide possibilities for changing the yarn.

  
 <EMI ID = 7.1>

  
Bead wire 2 by interlinking hooks as shown at 3. This allows the bead wires to raise or lower the needles so that they follow the paths required by the knitting method which will be described.

  
The bead wires connected to the needles which are to knit an individual diamond, for example B with its overlapping or ornamental threads 0 and 0 ', are made to pass between leveling cams 4 and 5. The or

  
the needles which are to knit an overlaid or ornamental yarn, namely yarn 0, are then selected by selector blades such as 7 acting on bead stops such as 8. The selected bead wires and the corresponding needles are then raised by a master cam 9 acting on the master stops 10 of the rods up to the release positions of the latches and the wire take-up indicated at 11.

  
After the selected needles have taken their thread, they are lowered by the action of a deselecting blade such as 12 acting on bead stops 13. After the needles have started to be lowered by this deselecting action, they are brought in line with. the needles not selected by a cam 14 acting on the master stops 10. At this point, a cam or selector blade 15 is caused to act on the rod stops such as 13 to lower the selected needles. This causes the stops 16 of the selected needles to pass down and below the front stitch cam 17, and forces them

  
 <EMI ID = 8.1>

  
taken previously from the thread feed 18. These needles then pass through the path 19 and below the rear stitch cam 20.

Claims

Unselected needles that need to knit the color

united or the body part of the same line of the diamond, go straight through

through leveling cams 4 and 5 and not being affected by

selectors 7 and 15, are lifted over the front stitch cam 17

to release their latches and to take another wire, namely the wire of

body, feed 21, and pass under a guard cam 22 and towards

down along the back stitch cam 20. So the body thread is

knitted on all needles except those that had been selected

to take the overlaid or ornamental thread. The thread of your uni is floated

across these selected needles.

This completes a diamond line. The next row is knitted in a similar way but in reverse order. The selector cams

and the thread feeding of the ornamental thread are repeated on the other side

of the cam block so that in the reverse stroke of the machine needles are selected to take another overlaid or ornamental thread

0 ', and knit it at the backstitch cam 20, in the same way as

that described above for running forward of the machine, after which

the rest of the needles knit the body yarn as before, only under the stitch cam 17. In this way a design is knitted.

of one thread, i.e. the overlaid or ornamental thread 0, and another thread,

that is to say the ornamental thread 0 ', in a fabric formed of a third thread,

that is, the body thread.

In this way, overlaid or ornamental lines, small

diamonds. and other designs can be knitted. When the lines

overlaid or ornamental are oblique as shown in Fig. 1, we will understand

that one or more different needles is or are selected in each

row so as to knit the overlaid or ornamental yarn in different

lines or groups of lines.

Although the above description has been limited to knitting

by reciprocating an area of fabric adorned with an overload of another color, it should be understood that the method can also be employed to ornament any desired area of fabric knitted in a direction of rotation, the nature of the design or ornamentation being

determined by the kind of ornamentation mechanism available.

The accompanying drawing shows only two selector blades 7, two

deselector blades 12 ,. two selector blades 15, and only two rod stops 8 and 13 in addition to the master stop 10. It should however be understood that the selector blades 7 are only two of the blades

of a certain number of similar blades, each of which is suitable for cooperating

in a well-known manner with one or a number of linkage stops of which only the stops 8 and 13 are shown by way of example.

Similarly, the deselector blades 12 are only two of the blades

of a certain number of deselector blades each of which is suitable for cooperating with one of the rod stops, the stops 8 and 13 of which are shown

5 tees as an example. Similarly, the selector plates 15 are only

two plates of a number of selector plates, each clean

to cooperate with a rod stopper such as 8 or 13. Such groups <EMI ID = 9.1>

of needles suitable for cooperating with them, are well known, and the blades

and remaining stops to form the complete groups have been omitted from the drawings for the sake of clarity and due to the fact that it does not seem necessary to represent them to illustrate the description of the conforming method

to invention.
