Description

TECHNICAL FIELD The present invention relates to a method of joining knitted fabrics by a flat knitting machine and the joined knitted fabrics.

When knitting clothes without sewing, a first knitted fabric such as a front knitted fabric and a second knitted fabric such as a back knitted fabric are joined at shoulder portions. Patent Document 1 (Patent No. 5619008) discloses knitting two wales for binding off between a first knitted fabric and a second knitted fabric. The first knitted fabric is bound off by forming double stitches of the stitches of the first knitted fabric and the stitches of the first bind off wale, and the double stitches of the stitches of the second knitted fabric and the stitches of the second bind off wale are formed. The second knitted fabric is bound off by forming. However, if the first knitted fabric or the second knitted fabric has a stepped portion, a hole will open in the vicinity of the stepped portion.

FIG. 2 of Patent Document 2 (Patent No. 5349268) discloses binding off a first knitted fabric and a second knitted fabric using two yarn feeders. In this knitting method, one yarn feeder is used for knitting the first knitted fabric and the second knitted fabric, and the other yarn feeder is used for bind off. In Patent Document 2, even if the first knitted fabric or the second knitted fabric is knitted in parallel with joining, a step for two stitches does not occur, and the hole at the stepped portion is inconspicuous. However, since the joining method of Patent Document 2 requires two yarn feeders, it takes time and effort to finish the yarn during mass production.

Prior art other than bonding is shown. It is known that the split stitch is used to widen a first stitch into two stitches, a new stitch and an old stitch. Further, Patent Document 3 (Patent No. 5695846) discloses widening by empty needle knitting and twisting.

SUMMARY OF THE INVENTION An object of the present invention is to provide a knitting method and a knitted fabric which can be knitted with a small number of yarn feeders and in which holes are not conspicuous at a stepped portion of a joining portion.

The present invention uses a flat knitting machine having at least a pair of front and rear needle beds,
The first knitted fabric and the second knitted fabric are joined by forming double stitches of the stitches of the end portions of the first knitted fabric and the second knitted fabric and the stitches of the bind-off wale,
In a method for joining knitted fabrics, wherein at least one of the first knitted fabric and the second knitted fabric has a stepped portion at the terminal end,
Using one yarn feeder, knitting the bind-off wale and the knitted fabric having the stepped portion,
As the bind-off wale, knitting a wale that forms the stitch at the end portion and the double stitch and an additional wale with the stitch at the end portion and the stitch that does not form the double stitch,
The knitted fabric having the stepped portion is widened on the lower side of the stepped portion to form an additional stitch generated by the widening and a double stitch of the additional wale.

Further, in the knitted fabric of the present invention, the first knitted fabric and the second knitted fabric are joined by the double stitches of the stitches at the ends of the first knitted fabric and the second knitted fabric and the stitches of the bind-off wale,
In the knitted fabric having a stepped portion at the terminal end of at least one of the first knitted fabric and the second knitted fabric,

The knitted fabric having the stepped portion is characterized by having widening stitches on the lower side of the stepped portion, and double stitches of the additional stitches generated by the widening and the stitches of the additional wale.

According to the present invention, the knitting can be performed with one yarn feeder, so that the yarn can be easily finished. In addition, even at the stepped portion, no conspicuous hole is formed at the joining portion of the knitted fabric. Furthermore, the additional wale increases the strength of the bind-off in the wale direction, thereby stabilizing the shape of the joint.

Preferably, the widening stitch is performed by split stitching, and one of the old stitches and the new stitches generated by the split stitch and the double stitch of the additional wale are formed, and the stitches of the bind off wale other than the additional wale are used to form the double stitches. A stitch positioned on the next course of the double stitch and a double stitch of the other stitch are formed. In this way, both the old stitch and the new stitch generated by the split stitch are connected to the bind off wale, so that the hole in the stepped portion becomes less conspicuous.

More preferably, in the knitted fabric having the stepped portion, a new stitch is formed in a wale on the lower side of the stepped portion adjacent to the wale on which the split knitting is performed, and the new stitches and the additional wale are not included. The double stitches of the stitches facing the new stitches are formed with the stitches of the bind off wale. By doing so, the new stitches are also joined to the bind off wale, so that the hole in the stepped portion becomes even less conspicuous.

Preferably, the bind off wale comprises at least one wale comprising a first wale forming the stitches and the double stitches of the first knitted fabric, a second wale forming the stitches and the double stitches of the second knitted fabric, and the additional wale. ,
After arranging the stitches of the bind off wale on the needle bed on the first knitted fabric side, the double stitches of the stitches of the second wale and the stitches of the end of the second knitted fabric are formed, and a new stitch is formed on the second wale. form,
After arranging the stitches of the bind off wale on the needle bed on the second knitted fabric side, the stitches of the first wale and the stitches at the end of the first knitted fabric are overlapped, and the next stitch is formed on the first wale. Form. In general, the back stitch has a smaller bulge than the front stitch, the stitch of the first wale is a back stitch when viewed from the first knitted fabric side, the stitch of the second wale is a back stitch when viewed from the second knitted fabric side, and the bulge of the bind off wale is become inconspicuous.

Preferably, the bind off wale includes a first wale forming the stitches and the double stitches of the first knitted fabric, a second wale forming the stitches and the double stitches of the second knitted fabric, and a widening stitch of the first knitted fabric. A first additional wale forming a double stitch and a second additional wale forming a widening stitch and a double stitch of the second knitted fabric are provided. With this configuration, the first additional wale prevents the formation of holes in the stepped portion of the first knitted fabric, and the second additional wale prevents the formation of holes in the stepped portion of the second knitted fabric.

The following is a preferred embodiment for carrying out the invention.

1 and 2 show the knitting method in the embodiment. The flat knitting machine used has four needle beds, FU (upper front), FD (lower front), BU (upper rear), and BD (lower rear), and stitches can be freely transferred between the front and rear needle beds. and each needle bed can be racked independently. However, using a flat knitting machine equipped with a pair of front and rear needle beds, the needles on the needle beds are divided into two sets with every other needle. Similar knitting can be achieved if the needles are regarded as needles in the lower needle bed. The black triangle is yarn feeder 1, which feeds yarn to the needle on the needle bed. Except for the case where a plurality of yarns are used for design reasons, only one yarn feeder is required, which simplifies the handling of the yarns at the start and end of knitting.

The stitch row held on the knitting needles A to G of the FD is the first knitted fabric 2, and the stitch row held on the knitting needles a to g of the BD is the second knitted fabric 3. In the embodiment, these are the front knitted fabric of the clothing. It is the back knitting fabric. In the embodiment, the first knitted fabric 2 and the second knitted fabric 3 are bound off using the bind off wales α, β, γ. In the example, the second knitted fabric 3 is pre-knitted along the shoulder and no new course is formed during joining knitting. On the other hand, in the first knitted fabric 2, a new course is knitted by flechage in parallel with the joining knitting. In this knitting, a bind-off wale γ as an additional wale is arranged at the extreme end position on the side of the first knitted fabric 2 as the front knitted fabric. Further, when a new course is knitted by turning back in order to provide a lower front, a stepped portion is generated at the end of the new course. When a stitch that is not connected to the bind-off wale is formed in the stepped portion, a hole is formed. According to the present invention, the hole is made inconspicuous at the step portion of the new course end portion due to the turning back.

For both the first knitted fabric 2 and the second knitted fabric 3, a new course may be knitted by turning back in parallel with the joining knitting. In this case, in addition to arranging the bind-off wale γ as an additional wale on the side of the first knitted fabric 2 that is the front knitted fabric at the extreme end, an additional wale is further added on the side of the second knitted fabric 3 that is the back knitted fabric. do it. Further, the type of knitted fabric to be knitted is not limited to clothing, and any knitted fabric may be used as long as it has a stepped portion due to the knitting of a new course in parallel with the joining knitting.

In this specification, a wale means a row of stitches connected to each other by a sinker loop and a needle loop, and a course means a row of stitches connected to each other by a crossover yarn between sinker loops.

For example, wales α, β, and γ for binding off the third stitch are provided, the inner wale α forms a double stitch with the stitch of the second knitted fabric 3, and the wale β is a wale for binding off the second knitted fabric 3. A wale for forming the stitches and double stitches of the first knitted fabric 2 and for binding off the first knitted fabric 2 . Also, wale γ is an additional wale,
・Increase the strength along the wale direction of the bind off portion composed of the bind off wales α, β, γ,
- By forming the stitches of the knitted fabric 2 and the double stitches at the stepped portion of the first knitted fabric 2, the holes are prevented from opening. The row of stitches held by the knitting needles A to G indicates the stitches of the first knitted fabric 2 and joins the stitches of the bind off wale β. Furthermore, the row of stitches held by the knitting needles a to g indicates the stitches of the second knitted fabric 3 and joins the stitches of the bind off wale α.

The S+ number indicates each step, and S0 indicates the initial state in splicing knitting. In S1, new stitches are formed on the wales γ, β, and the stitches of the wales α, β, γ are transferred to the needle bed FD. In S2, the needle bed BD (BU) is racked to the right, the stitch held on the knitting needle a of the second knitted fabric 3 is superimposed on the stitch of the wale α, and a new stitch is formed in the wale α in S3. In S4, the needle bed BD (BU) is racked leftward, the stitches of the wales α, β, and γ are transferred to the needle bed BD, racking is further leftward in S5, and the knitting needle A of the first knitted fabric 2 is moved. Overlap the stitches held on the wale β. The state of the knitted fabric after executing S5 is almost the same as the state of S0.

At locations other than the stepped portion, the process returns from S5 to S1, and the cycle of S1 to S5 is repeated. By executing S1 to S5 once each, the first knitted fabric 2 and the second knitted fabric 3 were bound off by one wale each, and one new stitch was formed on each of the bind off wales α, β, and γ.

The stitches of the wale β joined to the first knitted fabric 2 are formed on the needle bed BD on the side of the second knitted fabric 3 (S1), and the stitches of the wale α joined to the second knitted fabric 2 are formed on the side of the first knitted fabric 2. A needle bed FD is formed (S3). In this way, the stitch of the wale β becomes a back stitch when viewed from the side of the first knitted fabric 2, the stitch of the wale α becomes a back stitch when viewed from the side of the second knitted fabric 3, and the bind-off loop at the time of joining is inside the joint. By arranging them, the bulge of the bind off wale can be reduced. This point also applies to S6, S12, and S14 in FIG.

In the embodiment, a new course is knitted on the first knitted fabric 2 by flechage in parallel with the joining knitting. When knitting a new course by turning back, S6 to S14 are executed following S5. After forming new stitches on the wales γ and β in S6, the stitches on the wales α, β and γ are transferred to the needle bed FD. In S7, the needle bed BD (BU) is racked rightward, and the stitches of the wales α, β, γ are transferred to the needle bed BU. In S8 and S9, the first knitted fabric 2 is knitted for two courses by turning back. In parallel with the flechage knitting, the needle bed BD (BU) is racked, and the knitting needle d holding the stitches of the additional wale γ and the knitting needle C forming the stepped portion face each other to form split knitting + double stitches in S10. prepare. Further, the needles holding these stitches face each other so that the stitch held on the knitting needle b can be transferred to the wale α.

Since two courses of the first knitted fabric 2 are knitted in S8 and S9, a stepped portion is formed between the stitches held by the knitting needles C and D. Therefore, in S10, a new stitch is formed in the stitch held on the knitting needle C, and this stitch is split knitted to branch into two stitches, the old stitch and the new stitch, which exist before the split knit. Then, for example, the old stitch m is superimposed on the stitch of the additional wale γ. Also, the new stitch generated by the split stitch becomes the stitch held on the knitting needle C, and this stitch is superimposed on the stitch of the wale β in subsequent steps. As a result, both the new and old stitches at the step portion formed in the first knitted fabric 2 are joined to the stitches of the bind off wale, and the hole at the step portion becomes inconspicuous. In S10, a new stitch is also formed on the stitch held on the knitting needle B on the right side of the knitting needle C of the first knitted fabric 2 . In S10, the new stitch for split knitting may be superimposed on the stitch of the wale γ. In addition, instead of the split stitch, the widening stitch is formed between the stitches held by the knitting needles B and C using racking, for example, by the empty needle knit + twist described in Patent Document 3, and the widening stitch is the stitch of the wale γ. You can layer it on.

In parallel with the split knitting, the stitch of the wale α is transferred to the FD in S10, and the stitch held on the knitting needle b of the second knitted fabric is superimposed on the stitch of the wale α in S11. Then, in S12, a new stitch is formed on the wale α. In S13, the stitch held on the knitting needle B of the first knitted fabric is superimposed on the stitch of the wale β, and the stitch of the wale α held on the knitting needle A of the FD is transferred to the knitting needle a of the BU. Then, in S14, new stitches are formed on the wales γ and β. The state of the knitted fabric after S14 is executed is substantially the same as the state after forming new stitches in S1 and before the transfer. After executing step S14, the stitches of the wales α, β, γ are transferred to, for example, the needle bed FD, and then S2 to S5 are executed. After that, the cycle of S1 to S5 is executed to bind off the stitches retained on the knitting needles C to G and the knitting needles c to g.

FIG. 3 shows an arrangement example of the bind off wales. (A) shows an example of binding in two rows of a bind-off wale δ for overlapping the stitches of the first knitted fabric 2 and the second knitted fabric 3 and an additional wale γ. The additional wale γ may be on either side of the wale δ. However, since the arrangement of (A) involves the formation of a third layer, it is difficult to knit. (B) shows an example in which an additional wale γ is assigned to the first knitted fabric 2 , a wale β is assigned to the bind off of the first knitted fabric 2 , and a wale α is assigned to the bind off of the second knitted fabric 3 . It is arbitrary to which wale the additional wale γ is assigned.

(C) shows the arrangement of bind-off wales when preventing holes from forming in the stepped portions of both the first knitted fabric 2 and the second knitted fabric 3 . In this case, two wales γ ₁ and γ ₂ are provided as additional wales, wale γ ₁ is used to prevent hole opening at the stepped portion of the first knitted fabric, and wale γ ₂ is used to prevent hole opening at the stepped portion of the second knitted fabric. Used for prevention. Also, the arrangement of the wales α, β, γ ₁ and γ ₂ is arbitrary. Three or more additional wales γ may be provided, but knitting becomes difficult.

As shown in FIG. 3(C), when an additional wale γ ₂ is provided and a new course is knitted in the second knitted fabric 3 in parallel with the bind-off, for example, after S14 in FIG. Adjust the arrangement of α, β, γ on the needle bed. Next, the knitting corresponding to S8 to S14 is performed by reversing the front and back of the needle bed, and split stitching is performed on the lower side of the step portion in order to prevent hole opening at the end caused by flechage knitting of the second knitted fabric 3. etc., and the old stitch or the new stitch at this time is superimposed _on the stitch of the additional wale γ2.

FIG. 4 shows the connection between the first knitted fabric 2 and the bind off wales β and γ in the example. In addition, the second knitted fabric is connected to the bind off wale α, but its illustration is omitted. Further, FIG. 5 shows the connection between the first knitted fabric 2 and the bind off wale β in a conventional example. The dotted lines in FIGS. 4 and 5 show the connection of stitches by double stitches, C1 to C3 are knitting courses, C1 is knitted to the right, and the binding wales γ and β are knitted in the upward direction from the bottom of the figure. Repeat the formation and turn your eyes down. Further, as the starting end of the stepped portion, C2 is knitted to the left, C3 is knitted to the right, and the steps are knitted with the courses C2 and C3 turned back. Compared with the embodiment of FIG. 4, the conventional example of FIG.
・ No additional wale γ
- The stitch m (the old stitch in the example) split at the step portion is not overlapped with the stitch of the wale γ. In the conventional example of FIG. 5, since the stitch r of the stepped portion is not connected to the bind off wale β, a hole is likely to open in the vicinity between the bind off wale β and the stitch r.

In FIG. 4, two courses (C2, C3) are knitted by flechage with respect to the old stitch (C1) held on the knitting needles D to J in parallel with the joining knitting. At this time, since a new stitch is formed in the stitches held by the knitting needles C and B, the height of the step portion is changed from the second stitch in FIG. 5 to the first stitch. Further, the stitch held on the knitting needle C is widened by split stitching or the like, for example, the old stitch m is overlapped on the stitch of the additional wale γ, and the new stitch p formed on the knitting needle C by split stitch or the like is overlapped on the stitch of the wale β. . Also, the stitch n held on the knitting needle B is superimposed on the stitch of the wale β. As a result, all the stitches on the outer periphery of the first knitted fabric 2 are overlapped with the wale β or γ in the vicinity of the stepped portion, so no holes are formed in the vicinity of the stepped portion. The knitting needle to be widened is not limited to the knitting needle C at the end on the lower side of the stepped portion, but may be the knitting needle B or the like adjacent thereto.

When the additional wale γ is provided, the number of stitches in the course direction increases and the bind-off width increases, so the strength of the bind-off wale increases. Therefore, when the present invention is applied to a garment, the bind-off wales α, β, γ are less likely to stretch when a force is applied in a direction parallel to the bind-off portion, and as a result, the shape of the garment is stabilized. It is also possible to adjust the degree of elongation by further reducing the number of stitches in the wale direction with respect to the additional wale γ by miss knitting.

FIG. 6 shows a joint portion of a garment knitted according to the embodiment, and FIG. 7 shows a joint portion of a garment knitted according to a conventional example without the additional wale γ. Although the hole is conspicuous at the joint portion in FIG. 7, the hole is not conspicuous on the side of the front knitted fabric (first knitted fabric 2) provided with the additional wale γ in FIG.

The embodiment has the following features.
1) Even if the first knitted fabric 2 or the second knitted fabric 3 has a stepped portion facing the bind off wale, the stepped portion does not have a hole.
2) When the number of wales for bind off is increased, the knitted fabric becomes difficult to stretch along the wale direction of the bind off, and the shape of the knitted fabric is stabilized.
3) Since the yarn can be knitted with one yarn feeder 1, the yarn can be easily finished. The additional wales γ need not be knitted with the same number of courses as the wales α and β, and the number of stitches in the wale direction of the additional wales γ may be smaller than the number of wales α and β in the wale direction.
4) The bulge of the bind-off wale can be hidden.

In FIG. 3, although the bind-off wales are shown up to a width of 4 wales, a larger number of bind-off wales, for example, about 20 wales, may be knitted. In this case, a large number of bind-off wales are arranged, for example, in half in a C-shape on opposing needle beds, and the bind-off wales α, β and additional wales γ ₁ , γ ₂ in the embodiment are placed near both ends of the C-shape. Deploy. In addition, among the stitches of the bind-off wale, the stitches other than the wales α, β, γ ₁ and γ ₂ (stitches excluding both ends of the C-shape) are knitted with front stitches (cotton stitches), and the raised wide shoulders are knitted. It can be used as a downcast eye.
