Description

The present invention relates to a method of knitting a knitted fabric for knitting a set-up portion serving as a starting end of the knitted fabric.

In the case of knitting a knitted fabric using a flat knitting machine, a punched thread stitch row consisting of punched threads is knitted on the needle bed of the flat knitting machine, and a set-up part is knitted continuously in the wale direction of the punched thread stitch row. do. A base knitting yarn different from the punched yarn is used for knitting the set-up portion. The base knitted fabric portion, which is the main body of the knitted fabric, is knitted continuously in the wale direction of the set-up portion. Here, the pull-out stitch row is knitted as a starting point for knitting the set-up portion, and is removed from the knitted fabric after the knitted fabric is knitted. That is, in the completed knitted fabric, the set-up portion becomes the starting end of the knitted fabric.

In a general method of knitting a set-up part, the end threads of the set-up part are not fixed, so the set-up part easily frays. In Patent Document 1, a stitch row for preventing fraying is knitted using a base knitting yarn, and some stitches of the stitch row are overlapped on the set-up portion, thereby making the set-up portion difficult to fray.

Japanese Patent Application Publication No. 2016-141905

Even in the knitted fabric obtained by the knitting method of Patent Document 1, the end yarns at the set-up portion must be manually tightened to prevent them from fraying. It is desired that this process, which used to be done manually, be performed by a flat knitting machine.

One of the objects of the present invention is to provide a method for knitting a knitted fabric in which end yarns at a set-up portion are treated on a flat knitting machine so as not to fray.

<1> The method for knitting the knitted fabric of the present invention is as follows:
Using a flat knitting machine including a first needle bed, a second needle bed facing the first needle bed, and a first yarn feeder,
In a method of knitting a knitted fabric, in which a set-up portion, which is a starting end of the knitted fabric, is knitted with a base knitting yarn fed from the first yarn feeder continuously in the wale direction of a thread stitch row knitted by the drawn threads. ,
a step A of moving the first yarn feeder from outside the knitting range of the thread-pulling stitch row toward the inside of the knitting range, and knitting an anchor stitch consisting of a hanging stitch with the base knitting yarn;
Step B of knitting a first stitch that is not continuous in the wale direction of the drawn yarn stitch row using the base knitting yarn;
a step C in which the first stitch is entwined with the sinker loop of the second stitch by knitting a second stitch that is continuous in the wale direction of the first stitch using the base knitting yarn;
A step of reducing the loop shape of the first stitch by applying tension to two sinker loops of the first stitch using a configuration provided in the flat knitting machine, and tightening the sinker loop of the second stitch by the first stitch. D and
After the step D, a step E of knitting the set-up portion is provided.

<2> In the method for knitting a knitted fabric according to <1> above,
In the step B, the first stitch may be knitted with twisted hooks.

<3> In the method for knitting a knitted fabric according to <1> or <2> above,
The flat knitting machine includes a racking mechanism that relatively racks the first needle bed and the second needle bed,
In the step D, tension may be applied to the two sinker loops by relatively racking the first needle bed and the second needle bed.

<4> In the method for knitting a knitted fabric according to <1> or <2> above,
The flat knitting machine is configured to be movable in the longitudinal direction of the first needle bed and the second needle bed, and includes a gripper that grips the base knitting yarn,
In the step D, tension may be applied to the two sinker loops by causing the gripper to grip the base knitting yarn and moving the gripper.

<5> In the method for knitting a knitted fabric according to any one of <1> to <4> above,
The flat knitting machine includes a cutter that cuts the base knitting yarn,
The method may include a step X of cutting the base knitting yarn with the cutter in the vicinity of the anchor stitch.

In the method of knitting a knitted fabric of the present invention, a first stitch that is not continuous in the wale direction of a pullout stitch row and a second stitch that is continuous in the wale direction of the first stitch are knitted, and a sinker loop of the second stitch is knitted. The first part is involved. Further, in the method of knitting a knitted fabric of the present invention, tension is applied to the sinker loop of the first stitch, so that the second stitch is tightened by the first stitch. By knitting the set-up portion in this state, the second stitch in the base knitting yarn is firmly fixed to the set-up portion. As a result, after knitting the knitted fabric, there is no need to manually treat the end yarns at the set-up portion so that they do not fray.

In the method for knitting a knitted fabric described in <2> above, a second stitch is knitted following the wale direction of the first stitch consisting of twisted hooks. In this case, since the two sinker loops of the first stitch intersect, the first stitch that tightens the second stitch is difficult to move. Therefore, the fixation of the base knitting yarn becomes stronger.

The method for knitting a knitted fabric described in <3> above can be carried out using a general-purpose flat knitting machine that is not equipped with a special mechanism. A racking mechanism is implemented in most flat knitting machines.

In the fabric knitting method described in <4> above, the base knitting yarn is directly pulled with a gripper to reduce the loop shape of the first stitch. As a result, the load on areas other than the area being pulled is reduced.

In the method for knitting a knitted fabric described in <5> above, the base knitting yarn is cut by a cutter near the anchor stitch. As a result, the productivity of knitted fabrics is improved because manual cutting work is no longer necessary.

FIG. 1 is a first knitting process diagram according to the method for knitting a knitted fabric described in Embodiment 1. FIG. 2 is a second knitting process diagram following FIG. 1. FIG. 3 is a loop diagram showing the locked state of the anchor stitch, first stitch, and second stitch formed in FIG. 1 on the needle bed. FIG. 4 is an explanatory diagram of the step of cutting the base knitting yarn by the cutter described in Embodiment 1. FIG. 5 is a first knitting process chart according to the method for knitting a knitted fabric described in Embodiment 2. FIG. 6 is a second knitting process diagram following FIG. 5.

Hereinafter, a method for knitting a knitted fabric according to an embodiment will be described based on the drawings. In the embodiment, the set-up portion is knitted by a flat knitting machine including a first needle bed, a second needle bed, and a first yarn feeder. More specifically, before knitting the set-up portion, knitting is performed to prevent the end threads of the set-up portion from fraying.

<Embodiment 1>
In Embodiment 1, a knitting example of the knitted fabric knitting method of the present invention using a four-bed flat knitting machine will be described based on the knitting process diagrams in FIGS. 1 and 2 and the loop diagram in FIG. 3. The four-bed flat knitting machine includes a lower front needle bed, a lower rear needle bed, an upper front needle bed, and an upper rear needle bed. Hereinafter, the lower front needle bed, the lower rear needle bed, the upper front needle bed, and the upper rear needle bed will be referred to as FD, BD, FU, and BU, respectively. FD and BD are facing each other. The FU arranged above the FD and the BU arranged above the BD face each other. FD and FU are first needle beds, and BD and BU are second needle beds. This flat knitting machine is equipped with a racking mechanism (not shown), and the FD and FU and the BD and BU can be racked relative to each other. Unlike this example, the flat knitting machine used for knitting may be a two-bed flat knitting machine.

"S+number" in the left column of FIGS. 1 and 2 indicates the number of the knitting process. The right column shows the knitting state in each knitting process. Black dots in the right column indicate FD, BD, and BU knitting needles. FU stitches are omitted in FIGS. 1 and 2. A gap 6g is formed between FD and BD. The circle mark in the right column indicates the stitch, the V-shaped mark indicates the hook stitch, and the inverted triangle mark indicates the first yarn feeder 9. The parts related to the knitting operation of each knitting process are shown with thick lines, and the stitches are filled out. The "I"-shaped vertical bar shown on the left side of the knitting needle is a reference line that virtually indicates the horizontal position of the needle bed. When the BD and BU are racked, the reference lines of the FD and FU and the reference lines of the BD and BU shift to the left and right.

Step S1 in FIG. 1 shows a state in which the thread stitch row 5 is locked in the FD and BD. The thread removal stitch row 5 is continuously knitted in the wale direction of a waste knitted fabric (not shown). The drawn thread stitch row 5 is composed of drawn threads 5Y. In the subsequent steps, the set-up portion 3 shown in FIG. 2 is knitted continuously in the wale direction of the drawn yarn stitch row 5.

In step S2 of FIG. 1, a part of the pull-out stitch row 5 that is locked on the FD is moved to the BU. Furthermore, in step S2, the first yarn feeder 9 that feeds the base knitting yarn 1 is moved to the right, and a plurality of anchor stitches 10 are knitted in the FD (step A). The number of anchor stitches 10 may be one. The first yarn feeder 9 is moving from outside the knitting range of the thread removal stitch row 5 toward the inside of the knitting range. The anchor stitch 10 is a hanging stitch formed on the empty needle, and is not continuous in the wale direction of the thread removal stitch row 5. The base knitting yarn 1 is a knitting yarn different from the drawing yarn 5Y.

In step S2, the first yarn feeder 9 is further moved to the right to knit the first stitch 11 consisting of hook stitches on the empty needles of the BD (step B). The first stitch 11 consisting of hook stitches is not continuous in the wale direction of the thread removal stitch row 5. The first stitch 11 may be located on the right side of the stitch 50 of the thread extraction stitch row 5. Stitch 50 is the rightmost stitch among the stitches in thread removal stitch row 5 that has been moved from FD to BU.

The above-mentioned step S2 is a so-called thread insertion process. A portion including a plurality of anchor stitches 10 in the FD is called a thread insertion portion 19. The base knitting yarn 1 is cut at the position of the white arrow in the subsequent process. By moving a part of the thread extraction stitch row 5 to the BU, the thread insertion section 19 is arranged outside the cylindrical extraction thread stitch row 5. As a result, the thread insertion section 19 is less likely to interfere with subsequent knitting.

In step S3, the stitches other than the rightmost stitch 50 among the stitches of the pull-out stitch row 5 that are locked in the BU are returned to the FD. Through this process, the thread insertion part 19 is pressed by the thread removal stitch row 5. Further, above the knitting yarn 1A that connects the anchor stitch 10 and the first stitch 11, the knitting yarn 5A that connects the stitch 50 and the stitch 51 intersects. Stitch 51 is the rightmost stitch among the plurality of stitches returned to the FD. In other words, stitch 51 is the stitch to the left of stitch 50 at the time of step S1. Both the knitting yarn 1A and the knitting yarn 5A are crossing yarns that cross between the FD and BD and cross the stitch gap 6g.

Furthermore, in step S3, the first yarn feeder 9 is moved to the left, and an additional stitch 13 consisting of a hanging stitch is knitted on the empty needle of BD. Through this process, the knitting yarn 1B that connects the first stitch 11 and the additional stitch 13 intersects above the knitting yarn 1A and the knitting yarn 5A, and the first stitch 11 becomes twisted. The twisted state of the first stitch 11 is maintained by the additional stitch 13.

Here, the configuration shown by the two-dot chain line in step S3 is the gripper 4. Gripper 4 is not used in embodiment 1. The configuration and usage of the gripper 4 will be explained in Embodiment 4, which will be described later.

In step S4, the first yarn feeder 9 is moved to the right, and a second stitch 12 following the first stitch 11 in the wale direction is knitted (step C). The loop diagram in FIG. 3 shows the locked state of the anchor stitch 10, the first stitch 11, and the second stitch 12 at the time when step S4 is completed. In FIG. 3, only one FD knitting needle and one BD knitting needle are shown. As shown in FIG. 3, the anchor stitch 10 is locked to the knitting needle of FD, and the second stitch 12 is locked to the knitting needle of BD. The second stitch 12 is continuous in the wale direction of the twisted first stitch 11. The first stitch 11 is entangled with the two sinker loops 121 and 122 of the second stitch 12.

Further, in step S4 of FIG. 1, after knitting the second stitch 12, the additional stitch 13 that is locked on the BD is moved to the empty needle of the FD. This movement of the additional stitch 13 is a preparation for step S5.

In step S5, after moving the first yarn feeder 9 to the left side of the second stitch 12, the BD and BU are racked relative to the FD and FU (step D). In this example, the BDs and BUs are racked to the right. Due to racking in S5, the knitting needles of BD shown in FIG. 3 move to the right. The sinker loop 111 of the first stitch 11 (corresponding to the knitting yarn 1A in step S3 in FIG. 1) is connected to the anchor stitch 10 that is locked to the FD, and the sinker loop 112 of the first stitch 11 (corresponding to the knitting yarn 1A in step S3 in FIG. 1) is connected to the anchor stitch 10 that is locked to the FD. The knitting yarn 1B (corresponding to the knitting yarn 1B) is connected to the additional stitch 13 (see step S4 in FIG. 1) that is locked to the FD. Therefore, when the first stitch 11 moves to the right along with the BD, tension is applied to the sinker loops 111 and 112, and the loop shape of the first stitch 11 becomes smaller. The sinker loops 121 and 122 of the second stitch 12 are tightened by the first stitch 11 having a smaller loop shape, and the second stitch 12 of the base knitting yarn 1 is fixed.

By moving the first yarn feeder 9 to the left in step S5, the base knitting yarn 1 is less likely to be pulled out from the first yarn feeder 9 during racking. When the first yarn feeder 9 is provided with a mechanism for suppressing the withdrawal of the base knitting yarn 1, it is not necessary to move the first yarn feeder 9 before racking. A specific example of such a mechanism is, for example, a pair of rollers that sandwich the knitting yarn described in JP-A No. 2021-172910.

In step S6 of FIG. 2, the stitch 50 is moved to the position where it was locked in S1 of FIG. 1, and the second stitch 12 is moved to the empty needle of the FD. After this step S6, the racking pitch of BD and BU returns to zero. In the subsequent step S7, the first yarn feeder 9 is moved to the right side of the second stitch 12, and then the first yarn feeder 9 is moved to the left to knit the fixed stitch row 2 (step E). The fixed stitch row 2 is continuous in the wale direction of all stitches on the left side of the second stitch 12 in the FD. All the stitches include the stitches of the pull-out stitch row 5 and the anchor stitch 10. The fixed stitch row 2 is part of the set-up portion 3. The method of knitting the set-up portion 3 is known and is not limited. For example, bag knitting may be performed after the plurality of stitches in the fixed stitch row 2 are distributed to the front and rear needle beds. In this case, a set-up portion 3 is formed by the fixed stitch row 2 and the bag-knitted portion.

In step S8, every other stitch in the fixed stitch row 2 is moved to BD. Step S8 is part of the known knitting method of the set-up section 3. Although not shown in this example, a set-up portion 3 is also knitted by a known method on the pull-out stitch row 5 that is locked to the FD and BD in step S8.

According to the knitting example of this example, the base knitting yarn 1 is firmly fixed to the set-up portion 3. Therefore, after knitting the knitted fabric, there is no need to manually treat the end yarns at the set-up portion so that they do not fray.

When the flat knitting machine is equipped with a cutter that cuts the base knitting yarn 1, the cutter may cut the base knitting yarn 1 in the vicinity of the anchor stitch 10 indicated by the white arrow S2 in FIG. 1 (Step X). The timing for cutting the base knitting yarn 1 is, for example, after step S8 in FIG. 2.

An example of the procedure for cutting the base knitting yarn 1 will be explained based on FIG. 4. FIG. 4 shows the base knitting yarn 1, the needle bed 6, the holding device 7, and the cutter 8. The left-right direction in FIG. 4 is the longitudinal direction of the needle bed 6, and the upward direction is above the needle bed gap 6g. The gap 6g is a gap between the FD and the BD, and is where knitting is performed using knitting needles. The holding device 7 is a device that holds the starting end of the base knitting yarn 1 on the outside of the needle bed in the longitudinal direction. The cutter 8 is arranged above the needle gap 6g and is configured to be movable in the longitudinal direction of the needle bed. The anchor stitch 10 indicated by a black circle is the leftmost anchor stitch 10 in step S2 of FIG.

FIG. 4A shows a state where step S8 in FIG. 2 has been completed. The anchor stitch 10 has already come off the needle bed 6 and is located below the needle gap 6g. Therefore, the cutter 8 cannot cut the base knitting yarn 1.

In FIG. 4(B), the holding device 7 is raised and the base knitting yarn 1 extending from the anchor stitch 10 to the holding device 7 is angled. By this operation, a portion of the base knitting yarn 1 near the anchor stitch 10 is positioned above the stitch gap 6g. Therefore, when the cutter 8 is moved to the vicinity of the anchor stitch 10 as shown in FIG. 4(C), the base knitting yarn 1 can be cut by the cutter 8 at a position near the anchor stitch 10. In addition, before FIG. 4(A), that is, at a stage when the first yarn feeder 9 is arranged outside the holding device 7, a mechanism for lifting the base knitting yarn 1 upward is arranged below the base knitting yarn 1. You can leave it there. In this case, the base knitting yarn 1 can be cut without raising the holding device.

<Embodiment 2>
In the second embodiment, a knitting example in which the first stitch 11 and the second stitch 12 are knitted in a procedure different from that in the first embodiment will be described based on FIG. The view of FIG. 5 is the same as FIGS. 1 and 2.

Step S1 in FIG. 5 shows a state in which the thread stitch row 5 is locked between the FD and the BD. In step S2, a part of the pull-out stitch row 5 that is locked on the FD is moved to the BU. Furthermore, in step S2, the first yarn feeder 9 that feeds the base knitting yarn 1 is moved to the right, and a plurality of anchor stitches 10 are knitted in the FD (corresponding to step A). In step S2, the first yarn feeder 9 is further moved to the right to knit the first stitch 11 consisting of hook stitches on the empty needles of the BD (corresponding to step B).

In step S3, the first yarn feeder 9 is moved to the left side of the first stitch 11, and then the first stitch 11 is moved to the FD. This step S3 brings the first stitch 11 into a twisted state.

In step S4, among the stitches that are locked in the BU, the stitches on the left side of the first stitch 11 are moved to the FD, and the first yarn feeder 9 is moved rightward to move the stitches in the wale direction of the first stitch 11. A continuous second stitch 12 is knitted. With this knitting, the first stitch 11 is entangled with the sinker loop of the second stitch 12. In step S4, a hanging stitch 14 is further knitted on the right side of the second stitch 12. The hook 14 facilitates the implementation of the next step S5.

In step S5, the first yarn feeder 9 is moved to the left to knit hook stitches 15 and tuck stitches 16. The hook 15 is formed on the empty needle between the second stitch 12 and the hook 14. The tuck stitch 16 is overlapped with the second stitch 12.

In step S6 of FIG. 6, the first yarn feeder 9 is moved to the right to knit a fixed stitch row 2 that continues in the wale direction of the second stitch 12, the pick stitches 15, and the pick stitches 14. In step S7, after moving the fixed stitch row 2 to the empty needles of the BD, the BD and BU are racked to the right. The racking direction may be to the left. The racking reduces the loop shape of the first stitch 11 (step S3 in FIG. 5), and the first stitch 11 tightens the sinker loop of the second stitch 12.

After step S7, the set-up portion 3 may be knitted by a known method, similar to the first embodiment.

<Embodiment 3>
In the third embodiment, a knitting example will be described in which the first stitch 11 is knitted by increasing the number of stitches. "Knitting" means moving the stitch R that is held on the knitting needle p of the needle bed P to the stitch q of the needle bed Q that is opposite to the knitting needle p, and knitting the stitch S pulled out from the stitch R on the knitting needle p. This is a known arrangement. Refer to FIG. 1 for explaining this example.

In this example, after the anchor stitch 10 is knitted in step S2 in FIG. 1, the stitch 50 is added. Due to the splitting, the stitch 50 is moved to the BD, and the first stitch 11 drawn from the stitch 50 is knitted. This first stitch 11 is pulled out from the stitch 50, but is not continuous in the wale direction of the stitch 50.

Next, the first yarn feeder 9 is moved to the left to knit a second stitch 12 that is continuous in the wale direction of the first stitch 11. Since the second stitch 12 is continuous in the wale direction of the first stitch 11, the first stitch 11 is entangled with the sinker loop of the second stitch 12. In this state, by racking BD and BU, the sinker loop of the second stitch 12 is tightened to the first stitch 11.

<Embodiment 4>
In Embodiment 4, an example of knitting in which the sinker loop of the first stitch 11 is directly pulled will be described based on FIG. 1.

In the fourth embodiment, steps S1 to S3 in FIG. 1 are performed. The flat knitting machine of this example includes a gripper 4 shown by a two-dot chain line. The gripper 4 is configured to be movable along the longitudinal direction of the needle bed independently of the first yarn feeder 9. The gripper 4 is configured to be able to grip the base knitting yarn 1 at the gap 6g.

The gripper 4 grips the knitting yarn 1B in step S3. Next, the first yarn feeder 9 is moved to the right, the additional stitch 13 is removed from the knitting needles, and the second stitch 12 is knitted. Finally, by moving the gripper 4 leftward or rightward, the knitting yarn 1B is pulled. As a result, the loop shape of the first stitch 11 shown in FIG. 3 becomes smaller, and the first stitch 11 tightens the sinker loops 121 and 122 of the second stitch 12. In the method of this example, no excessive load is applied to stitches other than the first stitch 11.
