Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for increasing stitches when knitting a fabric on a flat knitting machine, and the present invention relates to a method for increasing stitches in an arbitrary course in an arbitrary wale of a knitted fabric of a predetermined width; The aim was to obtain a structure with no holes in the selvedge positions, and to obtain a knitted fabric with uniform selvedge wales.

When knitting clothing such as a sweater, it is common practice to determine the shape of a knitted fabric in advance according to the shape of the body, and then increase or decrease the number of wales in a predetermined course to knit the knitted fabric in a predetermined shape.

However, when increasing the knitting width, if the increasing wales are located on both sides of the knitted fabric, as shown in Figure 1, which schematically shows the development of the sleeve part of the garment, the wales of selvage are located in the middle of the knitted fabric. If the sleeves are constructed by sewing selvage in order to gradually increase from the course of
The other parts now have a straight line shape. Therefore, the third
As shown in the figure, if you widen any wale of any course, the wale of selvage will be in a straight line, and when combing or linking selvage, it can be done easily and neatly, and As shown in FIG. 4, the sleeves thus made can have a uniform bulge throughout.

Furthermore, when the conventional intermediate wale was widened, a relatively large hole was created in the widened part, as shown in FIG.

The present invention relates to a method of knitting a knitted fabric that eliminates the above-mentioned conventional drawbacks, and an example of the method of the present invention will be explained below with reference to the drawings.

A knitting machine for carrying out the method of the present invention is provided with a pair of needle beds with their tips butted against each other, for example, two gold beds in the front and back are provided in a pair in an inverted V-shape, and the needle beds in the front and back are respectively provided. ``Secondly, use a flat knitting machine equipped with a reciprocating carriage.'' The front and rear carriages each have one or more sets of locks.

FIG. 5 shows the arrangement of the cams constituting the lock 1 provided on the carriage, and the needle 2° needle jack 3. Shows Plenosar 4. The compressor 4 moves within the groove by known mechanical and electrical means to move the bat 41 to A,
A click stop can be made at any of the three positions B and C. The front and rear locks provided on the front and rear carriages are arranged so that their centers are on the same line. The lock 1 is provided with a rising cam 6, a movable guard cam 6, a fixed guard cam 7, and a transfer rising cam 8 along the center line, all of which are symmetrical. Therefore, from now on, the symbols for the left part of each part of the cam will be explained by adding a to the symbol of the symmetrical structure part of the right part of the cam. The rising cam 6 has a chevron shape, and the shoulder part has two almost horizontal lines. A guide surface 51.52 is provided between the sloped guide surfaces 53, 54, 55.

At the center of the rising cam 6, following the slope 66, 668, provide four parts 67, 578 with a depth that allows the needle jack butt 31 to pass through, and at the center of the four parts 57, 67a, provide the transfer receive cam 9 so that it can freely appear and retract. The cam 9 has inclined surfaces 91, 91 on both sides that become higher toward the center.
A triangular cam 94 having guide surfaces 93 and 938 on the sides is provided at the center of the plane 92 between the inclined surfaces 91 and 918.

The triangular cam 94 is at the same height as the rising cam 5 when the transfer receive cam 9 protrudes. The transfer receive cam 9 has a guide surface 96° 958 on the upper edge including the top of the triangular cam 94. The movable guard cam 6 has legs opened in a roughly V-shape, and the guide surface 1 of the fixed guard cam whose lower inner surface is a guide surface 71.
．． It is located in a state where it is held in the middle of the rising cam 1a, and has a guide surface 61 on its lower surface that faces the guide surfaces 54, 52, 55 of the rising cam 6 at a constant distance. The movable guard cam 6 is moved in and out of the drawing in a direction perpendicular to the plane of the paper by a mechanism not shown. The space between the movable guard cam 6 and the rising cam 6 becomes a course through which the needle jack 30 butt 310 passes when the movable guard cam 6 protrudes.

The top of the guide surface 71 of the fixed guard cam 7 is a horizontal guide surface 62
, 628, and a downward protruding part 4 is formed between the horizontal guide surfaces 62 and 628. The transfer rising cam 8 is located at the upper part of the fixed gird 7, has a chevron shape with guide surfaces 81 and 818 made of slopes on both sides, and has a recess 82 formed at the top.

Reference numeral 9 denotes a stitch cam, which is provided at a predetermined distance from the guide surface 53 of the rising cam 6 and is vertically slidable in contact with the fixed guard cam 7. A stitch cam 10 is provided symmetrically to the stitch cam 9, has a predetermined distance from the guide surface 53a of the rising cam 5, and is provided so as to be vertically slidable in contact with the fixed guard cam 7. 11
is the guide cam. Reference numeral 12 denotes a presser cam, which is freely retractable in the direction perpendicular to the plane of the drawing, and when the presser cam 12 protrudes, it engages with the butt 41 of the presser 4, and pushes the presser 4 into a known groove in which the presser 4 is fitted. The pressed presser cam 12 pushes the needle jack 3 into the needle groove and prevents the needle jack butt 31 from engaging with the lock.
are arranged in three rows, with two-stage bushings 12-1,
12-2, 12-1a are placed on the bat 41 at position A of planosaur 4, and 12-3, 12-3a in the middle stage is placed on the bat 41 at position B ffl of -4, -
Plenosaur 12-4 of the G stage.12-48 is Brefsa-4
When the presser cams 12 are respectively engaged with the butts 41 at the 00 position and the presser cams 12 are protruding, the presser butts 41
Pressing causes the needle jack 3 to be pushed into the metal groove 1 by the presser 4.

Next, the method for knitting the knitted fabric of the present invention will be explained.

In the example shown in Fig. 16, when knitting with plain knitting, the wale W
This is an example of increasing the amount of water for every 3 courses. I'll explain next by following the movement of the sword in Wale W as it increases.

The knitted fabric is knitted using a pair of gold I beds arranged in a chevron shape, with a hook 2 on the inner front needle bed. Push the button on the rear needle bed to 2a.
Tozuro. As is the case with the general construction of a course without increase, all the needle jacks 3 are connected to the plexer 4 as the gear ridge advances (it advances in the direction of the arrow in Fig. 5).
The butt 31 is brought into contact with the guide surface 63 of the rising cam 5 without being subjected to the suppressing action of the rising cam 5, and the guide surface 51,
54°52.55, the needle jack 73 rises by contacting the bat 31, and the gold 12 integrated with the needle jack 3
reaches the highest position by the rising cam 5. At this time, since the twenty-one dollar jack Basotho 32 has a low bat, it does not engage with any of the cams.

When the ail of this flat knitting course is formed, the movable gird cam 6 protrudes and maintains the same height as the rising cam 6, the fixed girt cam 7, etc. The needle jack butt 31 that has reached the highest position is lowered by the guide surface 61a of the movable guard cam 6, during which yarn feeding is performed and the stitch cam 10
The needle 2 comes into contact with a and is further pulled down, passing through the stitch loop of the previous course and knitting a new course.

When knitting a course for increasing stitches, the transfer rising cam 8 is protruded from the lock 1 of the carriage on the front needle bed, and the i7J moving guard cam 6 is retracted, and the lock 1 of the carriage on the front needle bed is moved. In the lock 1, the transfer rising cam 8 is recessed, and the movable guard cam 6 and the transfer receiving cam 9 are made to protrude.

All the needles 2 on the front needle bed are raised as in the case of knitting the plain knitting of the previous course. For this purpose, the plane sirer 4 is not operated, and as the carriage moves, the butt 31 of the needle jack 3 is engaged with the guide surface 53 of the rising cam 6, and the needle jack 3 is raised.

When the needle jack butt 31 reaches the guide surface 51 and moves parallel to the progression of the gear ridge, the needle jack butt 32 comes into contact with the guide surface 81 of the protruding transfer rising cam 8, and the needle jack butt 3
2 rises. At this time, since the movable guard cam 6 is recessed, the needle jack butt 31 does not engage with the cam 6 and moves along the guide surface 71 of the fixed guard cam 7, and the needle jack 3 rises according to the transfer rising cam 8. I will do it. As the needle jack 3 rises, the hook 2 integrated with the needle jack 3 also rises, and the loop of the knitted fabric engaged with the stepped portion 21 of the needle 2 also rises to its highest position. As the gear ridge continues to shift, the needle jack butt 31 comes into contact with the downward protrusion 74 of the fixed guard cam 7, and at the same time, the needle jack butt 32 is positioned at the fourth part 82 of the transfer rising cam 8, and the needle jack 3 is slightly lowered. Due to this lowering, the loop L that has been engaged with the stepped portion 21 of the needle 2 becomes slightly loosened. The above is the state of the needle 2 on the front needle bed, but on the rear needle bed, only the hook 2a corresponding to the wale to be stitched is raised. The ff112
In order to put the needles other than a in a resting state, the butt 41 of the planecer 4 corresponding to the needle is moved to position A by a known mechanical or electrical means (not shown) and raised ◇12a Only the Plenosaur 4 is raised to the B position, for example. -And Plenosaur 12-1, 12-2
．． If the carriage is moved by protruding the presser cam 12-3, the presser butt 41 at position A will be moved to the presser cam 12-3.
The needle jack butt 31 engages with the rising cam 5 . Transfer cash register - without any combination with Bookcam 9 etc.
In other words, the gear ridge passes through without raising the needle 2.

The breather 4, which is in the raised position B, engages with the shower cam 12-3 due to the movement of the carriage and pushes the needle jack 3 into the hook r114 to be pushed. This, tL Ni, Needle Jack Butt 3
1 moves straight without engaging with the guide surface 53 of the rising circuit 5, but when the brefsur cam 12-3 and the presano piece 41 no longer engage with each other, the needle jack butt 31
will protrude from the saw groove. This position is exactly the position of the recess 57 of the rising cam 5. Next, the jack butt 31 ascends the slope 91, is pushed in slightly by the plane 92, engages with the guide surface 93 of the triangular cam 94 of the transfer receive cam 9, and is moved upward by the triangular cam 94. When the needle jacket 31 comes close to the top of the triangular cam 94, it comes off the plane 92 due to the force of the needle jack 30, is guided by both the guide surface 96 and the guide surface 93, and connects to the top of the triangular cam 94. At this time, the butts 31, 32° 41 are on the X-ray line in Figure 5.The needle 2a on the rear needle bed has its top slightly inserted into the lead 22 of the needle 2 on the front needle bed. The state of the needles 2, 2a is shown in FIG.

In addition, in the above theory 1, the needle 2 is attached to the front carriage.
5 and the raising of the needle 2a by the carriage on the rear surface are explained using FIG. The above method was used to explain the situation in an easy-to-understand manner. The same applies to the explanation above.

Next, due to the movement of the carriage, the butt 32 of the needle jack 3 on the front plate 1 engages with the ascending guide surface of the four parts 82 of the transfer rising cam 8, and the needle 2 reaches the highest position.
□ raise the loop L, which is locked to the stepped part 21 of the hook 2, to face the top of the needle 2a on the rear needle bed. At this time, the needle jack 3 of the needle 2a is
Transfer the butt 31 to the guide surface 9 of the transfer receive cam 9
5a, the needle 2a also rises slightly, and the head of the needle 2a looks over the loop L. At this time rose 1-3
1.32.44 is on the Vll line in FIG. 5, and the state of the fly is as shown in FIG. 7. As the gear ridge continues to advance, the butt 31 on the front needle bed moves along the guide surface 72a, and its height remains unchanged, but the butt 31 on the rear needle bed rises along the guide surface 95a of the transfer receive cam 9. and take the position shown in Figure 5--111. At this time, as the butt 31 rises, the rear needle bed Q12a enters the lead 22 of the needle 1 and passes through the loop L at the same time (
Figure 8). As the carriage advances, the needle jack 30 butt 31 on the front needle bed engages with the guide surface 1a of the fixed guard cam 7 and is pulled down, and the needle jack 30 butt 31 on the rear 61 bed is also pulled down by the guide surface 58a. Take the position shown in Figure 5 IX. At this time, as shown in FIG. 9, the thread 12.2a is lowered and the loop L is applied to the needle 2a, and the loop L is removed from the beam 22 and shifted to the neck t% of the needle 2. At this time, the thread feeding beak 20 Butt 31 of needle jack 3 on the needle bed is
The hook 22 of the needle 2 catches the thread 30 which has been pushed down to the lowest part of the fixed guard cam and is sheathed as shown in FIG. 10, and attempts to pull it into the loop L.

And the hook 2 on the rear needle bed is the needle jack butt 3.
1 is moving parallel to the guide surface 59a at the same height as before, so the loop L remains in the applied state. At this time, 31, 32, and 41 are on the X-ray in FIG. In history, when the gear ridge advances and the butts 31 and 32 are on the X-ray line in FIG. The needle 2a on the rear needle bed passes through the loop L, and the needle jack hat 31 of the needle 2a on the rear needle bed
6 is one or two garro. At this time, the brake cam 12-3a
Since the presser bat 41 is pushed, it jumps over the edge of the rising cam 5 and stops at that height. At this time, the rear jf, the secondary body 10a of the sushi floor rises and does not come into contact with the needle jack butt 31. As the gear ridge moves forward and backward, the needle jack butt 31 is lowered to the lowest position of the stage cam, and the needle assumes the most negative position, as shown in FIG. 5, X11.

At this time, Φ12 on the front needle bed passes the newly fed yarn 30 through the loop L to create a new loop La, and the needle 2a on the rear needle bed locks a part of the loop L to create a new loop. Make Lb. Therefore, the loop La is on the front needle bed side, and the loop Lb is on the front needle bed side.
G is made on the rear needle bed side, and flat stitches are made one after another on the front needle bed side by the needles adjacent to needle 2, but G is made on the rear needle bed side.
Only one loop Lb is created by jJ needles 2a. This state is shown in FIG.

When the knitting of the course is completed in the above manner, when the carriage turns back, the carriage reverses without taking the yarn feeding beak 20 with it, that is, without feeding yarn to the needles, and moves to the front (k1 floor). The loops mW, LX, LY・1, which are attached to the needles 2W, 2X, 2Y, etc. adjacent to the metal 12, which fixes the loops La, are attached to the needles 2W, 2X, 2Y, etc.
Needles 2aW, 2a on the rear needle bed opposite to 2Y...
Move to X, 2aY... (Figure 14). This transfer may be performed by conventionally known general means. It goes without saying that the same transfer copper as the Φ blinders 12, 2a described above may be used. By the above transfer [], the knitted fabric is hung on either the right or left side of the knitting [4J] on the sword of the front needle bed, and the other side is left with only the knitted fabric.

When the above-mentioned mouth transfer is completed, rack the front metal 1 bed by 1 pitch to the side where the knitted fabric is hanging. Then, by moving the carriage without carrying the yarn feeding beak, the plan 12a of rearwardization of one bed is carried out by conventional means.

Transfer LX... to the needles 2W, 2X, 2Y... on the front needle bed opposite to the sub-2a, 2aW... As a result, the two loops La and Lb created by the above means are locked to the needles 2 and 2W of the front needle bed, respectively. is shown in FIG.

After that, knit as usual using the needles on the front needle bed.
In Example-C shown in FIG. 16, G is increased by 1'' again after 2 courses in the same manner as above.

In the method O of the present invention, as described above, the first. Of the first and second Φ1 supported by the needle beds provided in the second front and rear 1st space J, the first needle of the increasing wale of the course knitted by the first needle Insert and lock the second gold 1 into the stopped needle loop, feed new yarn to the first needle, and pull down the first needle to remove the loop that was locked to the first needle. Let them go through a new loop, and also
The second Φ that is locked to the needle loop that is locked to the needle of
1 is also pulled down, and the needle loop is locked on a set of first and second needles facing each other in a given wale, and from the needle adjacent to the first gold 1 to the side edge of the knitted fabric ◇1. Transfer the locked needle loops to the second needles 1 on the opposite sides, move the first needle 1 bed one pitch to the side where the first needle is locking the needle loops, and Since the needle loop that is attached to the button has been transferred to the first gold thread 1, the stitches can be increased in any wale or course of the knitted fabric of the specified rlJ, Since the selhage wale of the knitted fabric is continuous from the start of knitting to the end of knitting, the knitted fabric knitted by the method of the present invention is free from ringing and other sewing operations afterward. It also has the characteristics of being efficient, giving a beautiful finish, and being able to be aligned.

Furthermore, in the method of the present invention, the structure of the widened part is widened by pulling out the sinker loop between adjacent wales and creating a new needle loop between the two wales, as in the conventional method, so that the product has a large transparency. Unlike those that produce holes, the two-dle loops of one wale are anchored to the sinker loops of the other wale as well as to the sinker loops of one adjacent wale, so that the method of the present invention can be used. The knitted fabric also has the characteristic that no holes are formed in the widened part.

In addition, there are 10 locks used to carry out the method of the present invention, and three positions can be selected: knit, tuck, and miss. The IJ of the lock can be reduced compared to the case where locks for lkl transfer are used on both sides of the lock. In addition, since the cam for transferring is provided in the center of the rising cam, the knitting operation and the transferring operation can be performed at the same time.
