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 purpose of this is to obtain a structure that does not have holes in the selvedge positions, and to obtain a knitted fabric with uniform selvage wales.

When knitting clothing such as sweaters, it is common practice to determine the shape of the 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. There is.
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. When the sleeves are constructed by sewing selvage to gradually increase from the course of The situation has become apparent. Therefore, as shown in Fig. 3, if the selvage wales are widened in any wale of any course, the wales of the selvage will be in a straight line, and when suturing or linking the selvage, it can be done easily and with good appearance.
In addition, the sleeves thus made can have a uniform bulge over the entire sleeve, as shown in FIG.

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 has a pair of needle beds with their tips butted against each other. uses a flat knitting machine equipped with a reciprocating carriage. The carriages on the front and rear needle beds 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, and presser 4 relative to the lock 1.
The presser 4 can move within the groove and click-stop the butt 41 at any of three positions A, B, and C by known mechanical and electrical means. The front and rear locks provided on the carriages on the front and rear needle beds are arranged so that their centers are on the same line.
Lock 1 is along the center line, rising cam 5,
A movable guard cam 6, a fixed guard cam 7, and a transfer rising cam 8 are provided, all of which are symmetrical. Therefore, hereinafter, the reference numerals for the parts left of the center of each part of the cam will be explained by adding "a" to the reference numerals for the symmetrical structural parts of the right part of the cam. The rising cam 5 has a chevron shape, and has two substantially horizontal guide surfaces 51, 52 at its shoulder portion between sloped guide surfaces 53, 54, 55. At the center of the rising cam 5, an inclined surface 56,
Following the recess 56a, recesses 57 and 57a having a depth through which the needle jack butt 31 can pass are provided.
A transfer receive cam 9 is provided in the center of 7, 57a so as to be freely retractable. The cam 9 has inclined surfaces 91, 91a on both sides that become higher toward the center,
At the center of the plane 92 between the inclined surfaces 91 and 91a, there is a triangular cam 94 having guide surfaces 93 and 93a on the sides.
is provided. The triangular cam 94 is at the same height as the rising cam 5 when the transfer receive cam 9 is protruding. The transfer receive cam 9 has guide surfaces 95, 95a on its upper edge including the top of the triangular cam 94. The movable guard cam 6 has legs opened in a roughly V-shape, and is sandwiched between the guide surfaces 71 and 71a of the fixed guard cam 7 whose lower inner surface is a guide surface 71, and the rising cam 5 is located on the lower surface of the fixed guard cam 7. guide surface 54,5
It has a guide surface 91 that faces 2 and 55 at a constant interval. And movable guard cam 6
moves in and out 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 5 becomes a course through which the butt 31 of the needle jack 3 passes when the movable guard cam 6 protrudes. Guide surface 7 of fixed guard cam 7
The tops of the horizontal guide surfaces 62, 62a form a downward protrusion 74 in the middle of the horizontal guide surfaces 62, 62a. Transfer rising cam 8
is located at the upper part of the fixed guard cam 7, and has a chevron shape with guide surfaces 81 and 81a made of slopes on both sides, and a recess 82 is 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 5 and is vertically slidable in contact with the fixed guard cam 7. 1
A stitch cam 0 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 a guide cam. Reference numeral 12 denotes a presser cam, which is freely retractable in the direction perpendicular to the plane of the paper, and when the presser cam 12 protrudes, it engages with the butt 41 of the presser 4 to push the presser 4 into a known groove in which the presser 4 is fitted. The pressed presser 4 forces the needle jack 3 into the needle groove and prevents the needle jack butt 31 from engaging the lock. The presser cams 12 are arranged in three rows, with the upper presser cams 12-1, 12-
2, 12-1a is attached to the butt 41 in the A position of the presser 4, and the middle presser 12-3, 12-
Butt 41 with 3a in position B of presser 4
When the lower pressers 12-4 and 12-4a are respectively engaged with the butts 41 of the presser 4 at the C position and the presser cam 12 is protruding, the presser butts 41 are pressed and the presser 4 moves the needle jack 3 into the needle groove. It acts to push inside.

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

The example shown in FIG. 16 is an example in which the wale W is widened every three courses when knitting by flat knitting. The movement of the needle in the wale W where the stitches are widened will be explained next.

The knitted fabric is knitted with needles 2 on the inner front needle bed of a pair of needle beds provided in a chevron shape. The needle on the rear needle bed is designated 2a. As usual, the course is organized without any increase, and as the career progresses (5th
In the figure, it is assumed that the vehicle moves in the direction of the arrow. ) All the needle jacks 3 move the butt 31 to the guide surface 53 of the rising cam 5 without receiving the pressing action of the presser 4.
following the surface 53, the guide surfaces 51, 5
4, 52, and 55, the needle jack 73 rises, and the needle 2, which is integrated with the needle jack 3, reaches the highest position by the rising cam 5. At this time, since the needle jack butt 32 has a low butt, it does not engage with any cam. When knitting this flat knitting course, the movable guard cam 6 protrudes and maintains the same height as the rising cam 5, fixed guard cam 7, etc. The needle jack butt 31, which has reached the highest position, is lowered by the guide surface 61a of the movable guard cam 6, during which yarn feeding is carried out, comes into contact with the stitch cam 10a, is further lowered, and the needle 2 passes through the stitch loop of the previous course. Organize a new course.

When knitting a course in which the stitches are increased, the transfer rising cam 8 is protruded when the carriage lock 1 on the front needle bed is set, and the movable guard cam 6 is retracted when the carriage lock 1 is set on the rear needle bed. 1, the transfer rising cam 8 is retracted and the movable guard cam 6 and transfer receiving cam 9 are protruded. 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 presser 4 is not operated, and as the carriage moves, the butt 31 of the needle jack 3 is pressed against the guide surface 53 of the rising cam 5.
to raise the needle jack 3.
When the needle jack butt 31 reaches the guide surface 51 and moves parallel to the advancement of the carriage, 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 32 Rise. At this time, since the movable guard cam 6 is recessed, the needle jack butt 31 does not engage with the cam 6, but moves along the guide surface 71 of the fixed guard cam 7, and the needle jack 3 moves toward the transfer rising cam. It will rise according to 8. As the needle jack 3 rises, the needle 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 carriage continues to move, 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 3
2 is a concave portion 82 of the transfer rising cam 8
, and the needle jack 3 is lowered slightly. 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 needle 2 on the front needle bed, but on the rear needle bed, needle 2a corresponds to the wale that increases the stitches.
only can be raised. In order to put the needles other than the needle 2a into a rest state, presser 4 corresponding to the needle
The butt 41 of the needle 2a is positioned, for example, at the A position by known mechanical or electrical means (not shown), and only the presser 4 of the needle 2a to be raised is raised to, for example, the B position. And Presser 12-1,1
2-2, 12-3 are projected and the carriage is moved, the presser butt 41 in the A position engages with the presser cams 12-1, 12-2, and each time the presser cams 12-1 and 12-2 engage, the presser 4 is pushed in and the needle jack is moved. In order to force the needle 2 into the needle groove, the needle jack butt 31 does not engage the rising cam 5, the transfer receiving cam 9, etc., ie, the carriage passes without raising the needle 2.
The presser 4 in the raised B position engages and presses the presser cam 12-3 due to the carriage transition, thereby forcing the needle jack 3 into the needle groove. As a result, the needle jack butt 31 moves straight without engaging with the guide surface 53 of the rising cam 5, but when the presser cam 12-3 and the presser butt 41 no longer engage, the needle jack butt 31 protrudes from the needle groove. It turns out. This position is exactly the recess 5 of the rising cam 5.
7 position. Next, the jack butt 31 moves up the needle surface 91, is pushed in slightly by the flat surface 92, engages with the guide surface 93 of the triangular cam 94 of the transfer receive cam 9, and is raised by the triangular cam 94. When the needle jack butt 31 reaches the vicinity of the top of the triangular cam 94, it comes off the plane 92 due to the elastic force of the needle jack 3, and the guide surface 95 and the guide surface 93
and comes into contact with the top of the triangular cam 94.
At this time, the butts 31, 32, and 41 are on the line in FIG. 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 at this time is shown in FIG.

In the above explanation, the raising of the needle 2 by the front carriage and the raising of the needle 2a by the rear carriage are explained with reference to FIG. Although the carriage shown in FIG. 5 is actually in a symmetrical state to that shown in FIG. 5, the above-mentioned means have been used to make the explanation easier to understand. The same applies to the following explanation.

Next, as the carriage moves, the butt 32 of the needle jack 3 on the front needle bed engages with the raising guide surface of the recess 82 of the transfer rising cam 8, and raises the needle 2 to the highest position. 21
The loop L that is engaged with the needle 2a is placed opposite the top of the needle 2a on the rear needle bed. At this time, the needle jack 3 of the needle 2a raises the butt 31 by the guide surface 95a of the transfer receive cam 9, and the needle 2a also rises slightly, so that the head of the needle 2a looks over the loop L. At this time, the butts 31, 32, and 44 are on the line shown in FIG. 5, and the needle is in the state shown in FIG. As the carriage continues to advance, the butt 31 of the front needle bed moves along the guide surface 72a, and although its height does not change, the butt 31 of the rear needle bed moves along the guide surface 72a.
1 is the guide surface 95 of the transfer receive cam 9
a and rise to the position shown in Figure 5. At this time, as the butt 31 rises, the needle 2 on the rear needle bed
a enters the lead 22 of the needle 1 and passes through the loop L at the same time (FIG. 8). As the carriage progresses, the butt 3 of the needle jack 3 on the front needle bed
1 engages with the guide surface 71a of the fixed guard cam 7 and is pulled down, and the butt 31 of the needle jack 3 on the rear needle bed is also pulled down by the guide surface 58a.
Take the position shown in Figure 5. At this time, as shown in FIG. 9, the needles 2, 2a are lowered, and the loop L is applied to the needle 2a, and the loop L is detached from the lead 22 and located at the neck portion of the needle 2. At this time, the yarn feeding beak 20 is
Feed the yarn to the hook. As the carriage continues to move, the butt 31 of the needle jack 3 on the front needle bed is pushed down to the lowest part of the fixed guard cam, and the hook 22 of the needle 2 engages the fed thread 30 as shown in FIG. It stops and tries to pull into loop L. The needle 2 on the rear needle bed is placed on the guide surface 59 with the needle jack butt 31 at the same height as before.
Since it is moving parallel to a, the loop L remains applied. At this time, bats 31, 32,
41 is on the fifth diagram line. Further, when the carriage advances and the butts 31 and 32 are on the line XI in FIG. Go through the
The needle 2a of the rear needle bed has its needle jack butt 31 raised on the inclined surface 56. At this time, the presser butt 41 is pressed by the presser cam 12-3a, so it jumps the edge of the rising cam 5 and remains at that height. At this time, the stitch cam 10a on the rear needle bed rises and does not come into contact with the needle jack butt 31. As the carriage advances further, the needle jack butts 31 of the front needles are lowered to the lowest position of the stitch cam, as shown in FIG. 5XII, and the needles assume the lowest position.
At this time, the needle 2 on the front needle bed is loaded with the newly fed yarn 3.
Pass 0 through loop L, create a new loop La,
The needle 2a on the rear needle bed locks a part of the loop L to create a new loop Lb. Therefore, the loop La is made on the front needle bed side, and the loop Lb is made on the rear needle bed side, and in front of the front needle bed, flat stitches are made one after another by the needles adjacent to needle 2. One needle 2a on the needle bed side
Only one loop Lb is created by . This state is shown in FIG.

When knitting of the course is completed as described above, when the carriage turns back, the carriage reverses without carrying the yarn feeding beak 20, that is, without feeding yarn to the needles, and the front needle bed is Needles 2W, 2X, 2Y adjacent to needle 2 that locks loop La
Loops LW, LX, LY that are locked to ......
are transferred to the needles 2aW, 2aX, 2aY... on the rear needle bed opposite to the needles 2W, 2X, 2Y... (Fig. 14). This transfer may be performed by conventionally known general means. Needless to say, the above-mentioned needles may be transfer needles similar to needles 2 and 2a. As a result of the above-described stitch transfer, the needles on the front needle bed are covered with knitted fabric on either the right or left side of the knitted width, and the other side is left with only the needles.

At the stage where the above stitch transfer is completed, set the front needle bed 1
Lattle it to the side where the knitted fabric is hanging by the pitch. Then, by transferring the carriage without carrying the yarn feeding beak, needle 2 in the rear needle bed is removed by the usual means.
Loop Lb that is locked to a, 2aW, 2aX...
Transfer LW, LX... to needles 2W, 2X, 2Y... on the front needle bed opposite to the needles 2a, 2aW.... As a result, the two loops La and Lb created by the above means are connected to the needles 2 and 2W of the front needle bed, respectively.
This means that one wale has been added here. This state is shown in FIG.

Thereafter, knitting is continued as usual using the needles on the front needle bed, and in the example shown in FIG. 16, the stitches are increased again in the same manner as described above after two courses.

In the method of the present invention, the first and second
Of the first and second needles each supported by a pair of front and rear needle beds, the first needle of the course knitted by the first needle is engaged with the first needle of the wale that is to be widened. Insert and lock the second needle into the needle loop that has been locked, feed a new yarn to the first needle, and pull down the first needle to insert a new loop into the loop that was locked to the first needle. At the same time, the second needle that is engaged with the needle loop that is engaged with the first needle is also pulled down, and the needle loop is engaged with a pair of first and second needles facing each other in a predetermined wale. stop,
A needle loop that is secured to a needle from a needle adjacent to the first needle to one side end of the knitted fabric is connected to a second needle opposite to the first needle.
, move the first needle bed one pitch to the side where the first needle locks the needle loop, and move the needle bed that is locked to the second needle to the opposite side. Since the stitches are transferred to the knitted needles, the stitches can be increased in any wale of a knitted fabric of a predetermined width or in any course, and the selvage wale of a knitted fabric can be knitted from the beginning of knitting of the knitted fabric. Since the knitted fabric is continuous all the way to the end, the knitted fabric knitted by the method of the present invention has the characteristic that it can efficiently produce a beautiful finish even in subsequent linking and other sewing operations.

Furthermore, in the method of the present invention, the structure of the widened part is enlarged by pulling out the sinker loop between adjacent wales and creating a new needle loop between both wales, as in the conventional method, so that there is a large transparency in this part. Unlike fabrics that have holes, the needle loops of one wale are locked to the sinker loops of that wale as well as the sinker loops of adjacent wales, so the knitted fabric knitted by the method of the present invention Another feature is that there are no holes in the widened area.

The lock used to carry out the method of the present invention is one lock, which can select three needle positions: knit, tuck, and miss, as well as receive and receive stitch transfer, and has eyes on both sides of the conventional knitting lock. The width of the lock can be reduced compared to a lock that uses a transfer lock. Furthermore, since the cam for receiving the stitches is provided at the center of the rising cam, knitting and transfer operations can be performed simultaneously.
