Description

[Technical field]

[0001] The present invention relates to a method for knitting a tubular knitted fabric in which two tubular portions adjacent in the knitting width direction are joined together. [Background technology]

[0002] A flat knitting machine is used to knit a tubular knitted fabric in which multiple tubular parts are joined. When joining two adjacent tubular parts, the stitches of one tubular part overlap the stitches of the other tubular part at the crotch position of both tubular parts to prevent holes from being formed at the crotch position. A typical example of a tubular knitted fabric in which multiple tubular parts are joined is a glove.

[0003] In Patent Document 1, two adjacent tubular parts are knitted with full needles and joined together using a knitting member called a razor. Full needle knitting is knitting a fabric with no empty needles between adjacent stitches on the needle bed. There is also a term called needle-out knitting as a counter term to full needle knitting. Needle-out knitting is knitting a fabric with empty needles arranged between adjacent stitches on the needle bed. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2000-220064 A Summary of the Invention [Problem to be solved by the invention]

[0005] In a flat knitting machine that does not have a special knitting member such as a razor blade, in order to join two tubular parts, it is necessary to knit two tubular parts at different positions in the knitting width direction and overlap the stitches of one tubular part with the stitches of the other tubular part. In order to overlap stitch A, which is at a different position on either the front or rear needle bed P, with stitch B, stitch A is moved to needle bed Q opposite needle bed P. Next, stitch A, which is held on needle bed Q by racking, is placed in a position opposite stitch B, which is held on needle bed P. Finally, stitch A is moved to stitch B. In this way, to move stitch A to a different position on needle bed P, an empty needle for transfer is required on needle bed Q. In a four-bed flat knitting machine that has a needle bed for transfer, two tubular parts can be knitted with all needles. However, in a two-bed flat knitting machine that does not have a needle bed for transfer, it is necessary to knit the two tubular parts with a needle-out knitting, which results in coarse stitches on the two tubular parts.

[0006] An object of the present invention is to provide a method for knitting a tubular fabric, which can join two tubular parts knitted with all needles by using a two-bed flat knitting machine. [Means for solving the problem]

[0007] <1> The knitting method of the tubular knitted fabric of the present invention comprises the steps of: A method for knitting a tubular fabric, using a two-bed flat knitting machine having a front needle bed and a rear needle bed, in which the knitting needles provided on the front needle bed and the rear needle bed are latch needles, knitting a right tubular part and a left tubular part adjacent in the knitting width direction with all needles, joining a front left stitch row of the right tubular part to a front right stitch row of the left tubular part, and joining a rear left stitch row of the right tubular part to a rear right stitch row of the left tubular part, a step A of knitting the right tubular portion and the left tubular portion so that an initial empty needle area is formed between the front left stitch row and the front right stitch row, and between the back left stitch row and the back right stitch row, the initial empty needle area is an area in which empty needles are arranged in the knitting width direction in a number equal to or greater than the number of stitches joining the front left stitch row and the front right stitch row and in a number equal to or greater than the number of stitches joining the back left stitch row and the back right stitch row, moreover, A process B of moving a first stitch row, which is any one of the four stitch rows, to the initial empty needle area adjacent to the first stitch row in a knitting width direction; A process C of overlapping a second stitch row, which is held on the same needle bed as the first stitch row, on the first stitch row among the four stitch rows; A process D of moving a third stitch row, which is different from the first stitch row and the second stitch row, among the four stitch rows, to the initial empty needle area adjacent to the third stitch row; and step E of overlapping a fourth stitch row, which is the last of the four stitch rows, onto the third stitch row.

[0008] Here, in this specification, the term "all-needle knitting" also refers to knitting a fabric in which most of the fabric is in a full-needle state. In other words, in this specification, the term "all-needle knitting" also refers to knitting a fabric in which a part of the knitting width direction of the fabric is in a needle-out state and the remaining part is in a full-needle state.

[0009] <2> the above <1> In the method for knitting a tubular knitted fabric described in After step E, it is possible to repeatedly move two rows of stitches diagonally across the joint in parallel to four new empty needle areas formed outside the joint where the stitches of the right tubular section and the stitches of the left tubular section are overlapped.

[0010] Here, the above-mentioned "moving two diagonally positioned stitch rows in parallel" means "moving two diagonally positioned stitch rows in accordance with the movement of a carriage provided on the flatbed knitting machine in one direction." The carriage is a member that moves along the needle bed and drives the knitting needles provided on the needle bed.

[0011] <3> the above <1> In the method for knitting a tubular knitted fabric described in After step E, the stitch rows on the outside of the new empty needle area may be repeatedly moved to four new empty needle areas formed outside the joint where the stitches of the right tubular section and the stitches of the left tubular section are overlapped, thereby moving the new empty needle area to the outside of the knitting range of the right tubular section and the left tubular section.

[0012] <4> the above <1> from <3> In the method for knitting a tubular knitted fabric according to any one of the preceding claims, The number of empty needles in the initial empty needle area on the front needle bed may be different from the number of empty needles in the initial empty needle area on the rear needle bed. Effect of the Invention

[0013] The knitting method for the tubular knitted fabric of the present invention can join a plurality of tubular parts knitted with all needles even when using a two-bed flat knitting machine equipped with latch needles.

[0014] the above <2> According to the knitting method for a tubular knitted fabric described in, after the right and left tubular parts are joined, the empty needles formed on the outside of the joint between the right and left tubular parts can be moved toward the outside of the knitting range of the right and left tubular parts. In this knitting method for a tubular knitted fabric, the rows of stitches diagonally across the joint are moved in parallel, so the number of steps required to move the empty needles is reduced.

[0015] the above <3> According to the knitting method of the tubular knitted fabric described in the above, the empty needles formed outside the joint between the right and left tubular parts after the right and left tubular parts are joined are moved to the outside of the knitting range of the right and left tubular parts. Therefore, there are no empty needles within the knitting range of the right and left tubular parts. In this case, when a larger tubular part is knitted continuously in the wale direction of the joined right and left tubular parts, the stitches of the larger tubular part do not become coarse.

[0016] the above <4> According to the knitting method of the tubular knitted fabric described in the above, the number of joints on the front side and the number of joints on the rear side of the right and left tubular portions can be made different. [Brief description of the drawings]

[0018] Hereinafter, a method for knitting a tubular knitted fabric according to an embodiment will be described with reference to the drawings.

[0019] <Embodiment 1> FIG. 1 shows a glove 7 as an example of a tubular knitted fabric. The glove 7 of this example includes finger pouches 70, 71, 72, 73, and 74 corresponding to the thumb, index finger, middle finger, ring finger, and little finger, respectively. The finger pouches 70, 71, 72, 73, and 74 are each a tubular portion knitted with a full needle. The glove 7 also includes a two-piece body 75, a three-piece body 76, a four-piece body 77, and a five-piece body 78 corresponding to the palm. These are also tubular portions knitted with a full needle in a tubular shape. In the crotch portion 79 formed between the finger pouch 71 and the finger pouch 72, between the two-piece body 75 and the finger pouch 73, between the three-piece body 76 and the finger pouch 74, and between the four-piece body 77 and the finger pouch 70, a part of two adjacent tubular portions is joined by a double stitch. The crotch portion 79 joined by a double stitch connects adjacent stitches in the course direction so that no holes are formed between the two tubular portions.

[0020] The glove 7 of this example is knitted in the following procedure. Finger pockets 71 and 72 are knitted with all needles from their respective tips. Finger pockets 71 and 72 are joined, and two-piece body 75 is knitted with all needles in the wale direction of the joined finger pockets 71 and 72. Next, two-piece body 75 is joined to finger pocket 73 knitted with all needles. In the same manner, three-piece body 76, finger pocket 74, four-piece body 77, finger pocket 70, and five-piece body 78 are knitted in this order to form each crotch section 79, and the glove 7 is completed.

[0021] In this example, the knitting method of the tubular knitted fabric of the present invention is applied to the formation of the crotch portion 79. Hereinafter, the knitting method of the tubular knitted fabric of the present invention will be described using the joining of finger bags 71 and 72 as an example. The flat knitting machine used for knitting is a two-bed flat knitting machine equipped with a front needle bed FB and a rear needle bed BB. The knitting needles equipped on the front needle bed FB and the rear needle bed BB are latch needles. The front needle bed FB and the rear needle bed BB are configured to be rackable relative to each other, and stitches can be transferred between the front needle bed FB and the rear needle bed BB. In the two-bed flat knitting machine of this example, the rear needle bed BB is configured to be rackable.

[0022] Figures 2 and 3 are specific knitting process diagrams. The "S+number" in the left column of the knitting process diagram indicates the knitting process number. The right column shows the state of the stitches on the needle bed of the flat knitting machine. The black dots in the right column indicate knitting needles, the circle marks indicate stitches, and the double circle marks indicate double stitches.

[0023] Step S0 shows a state in which the right tubular portion 8 and the left tubular portion 9 adjacent in the knitting width direction are knitted with all needles. In this example, "right" and "left" respectively refer to the directions when looking from the front needle bed FB to the back needle bed BB. In this example, the left tubular portion 9 is a finger pocket 71, and the right tubular portion 8 is a finger pocket 72. No empty needles are arranged within the knitting range of the right tubular portion 8 and within the knitting range of the left tubular portion 9. For ease of explanation, the number of stitches in the right tubular portion 8 and the left tubular portion 9 is shown as being less than the actual number.

[0024] In this example, the front left stitch row 80F of the right tubular portion 8 and the front right stitch row 90F of the left tubular portion 9 are joined, and the back left stitch row 80B of the right tubular portion 8 and the back right stitch row 90B of the left tubular portion 9 are joined. The front left stitch row 80F is a stitch row consisting of some of the stitches including the end stitches on the left tubular portion 9 side among the stitches held on the front needle bed FB of the right tubular portion 8. The front right stitch row 90F is a stitch row consisting of some of the stitches including the end stitches on the right tubular portion 8 side among the stitches held on the front needle bed FB of the left tubular portion 9. The back left stitch row 80B is a stitch row consisting of some of the stitches including the end stitches on the left tubular portion 9 side among the stitches held on the back needle bed BB of the right tubular portion 8. The back right stitch row 90B is a stitch row consisting of some of the stitches including the end stitches on the right tubular section 8 side out of the multiple stitches held on the back needle bed BB of the left tubular section 9. The number of stitches in each of these four stitch rows 80F, 90F, 80B, 90B is three. That is, the number of joining stitches between the front left stitch row 80F and the front right stitch row 90F is three, and the number of joining stitches between the back left stitch row 80B and the back right stitch row 90B is also three. The number of joining stitches is not limited to three, and may be one, two, or four or more.

[0025] The right tubular portion 8 and the left tubular portion 9 are knitted so that an initial empty needle area 5F and an initial empty needle area 5B are formed between the front left stitch row 80F and the front right stitch row 90F, and between the back left stitch row 80B and the back right stitch row 90B, respectively (step A). ​​The initial empty needle areas 5F and 5B are areas in which empty needles equal to or greater than the number of joined stitches are lined up in the knitting width direction. In this example, the initial empty needle areas 5F and 5B are each formed by three empty needles.

[0026] From the state of step S0, the front left stitch row 80F is the first stitch row 1, the front right stitch row 90F is the second stitch row 2, the back right stitch row 90B is the third stitch row 3, and the back left stitch row 80B is the fourth stitch row 4, and joining of the right tube portion 8 and the left tube portion 9 is started. It is arbitrary which stitch row of the four stitch rows 80F, 90F, 80B, and 90B is to be the first stitch row 1. However, the second stitch row 2 is a stitch row that is held on the same needle bed as the first stitch row 1. In addition, the third stitch row 3 is one of two stitch rows that are held on a needle bed opposite to the needle bed on which the first stitch row 1 is held. The fourth stitch row 4 is a stitch row that is held on the same needle bed as the third stitch row 3.

[0027] In step S1, the rear needle bed BB is racked three pitches to the right relative to the front needle bed FB, the initial empty needle area 5B is positioned opposite the first stitch row 1, and then the first stitch row 1 is moved to the initial empty needle area 5B (part of process B). By moving the first stitch row 1, a new empty needle area 5W is formed to the right of the initial empty needle area 5F. The number of empty needles in the new empty needle area 5W is the same as the number of stitches in the first stitch row 1, which is 3.

[0028] In step S2, the rear needle bed BB is racked three pitches to the left, and the first stitch row 1 held by the rear needle bed BB is positioned opposite the initial empty needle area 5F, and then the first stitch row 1 is moved to the initial empty needle area 5F (the remainder of process B).

[0029] In step S3, the rear needle bed BB is racked three pitches to the left, and the initial empty needle area 5B is positioned opposite the second stitch row 2, after which the second stitch row 2 is moved to the initial empty needle area 5B (part of process C). By moving the second stitch row 2, a new empty needle area 5X is formed to the left of the first stitch row 1. The number of empty needles in the new empty needle area 5X is three.

[0030] In step S4, the rear needle bed BB is racked three pitches to the right to position the second stitch row 2 opposite the first stitch row 1, and then the second stitch row 2 is overlapped on the first stitch row 1 (the remainder of process C).

[0031] In step S5, the third stitch row 3 is moved to the new empty needle area 5X (part of process D). By moving the third stitch row 3, a new empty needle area 5Y is formed to the left of the initial empty needle area 5B. Furthermore, in step S5, the fourth stitch row 4 is moved to the new empty needle area 5W (part of process E). By moving the fourth stitch row 4, a new empty needle area 5Z is formed to the right of the initial empty needle area 5B.

[0032] In step S6, the rear needle bed BB is racked three pitches to the left to position the initial empty needle area 5B opposite the third stitch row 3, and then the third stitch row 3 is moved to the initial empty needle area 5B (the remainder of process D).

[0033] In step S7, the rear needle bed BB is racked 6 pitches to the right, and the fourth stitch row 4 is positioned opposite the third stitch row 3, and then the fourth stitch row 4 is overlapped on the third stitch row 3 (the remainder of process E). By steps S1 to S7 described above, a joint 6 is formed where the stitches of the right tubular portion 8 and the stitches of the left tubular portion 9 are overlapped.

[0034] Next, the stitch rows 11, 21, 31, 41 on the outside of the new empty needle areas 5W, 5X, 5Y, 5Z are repeatedly moved to the four new empty needle areas 5W, 5X, 5Y, 5Z formed on the outside of the joint 6, and the new empty needle areas 5W, 5X, 5Y, 5Z are moved to the outside of the knitting range of the right tube portion 8 and the left tube portion 9. The number of stitches in each of the stitch rows 11, 21, 31, 41 is the same as the number of empty needles in each of the new empty needle areas 5W, 5X, 5Y, 5Z, that is, three. A specific knitting procedure will be described with reference to FIG. 3.

[0035] In step S8, the stitch row 11 on the right side of the new empty needle area 5W is moved to the new empty needle area 5Z, and the stitch row 31 on the left side of the new empty needle area 5Y is moved to the new empty needle area 5X. The stitch rows 11 and 31 are diagonally positioned across the joint 6. The stitch rows 11 and 31 are moved to the new empty needle areas 5Z and 5X in parallel with the movement of the carriage in one direction. In other words, the two stitch rows 11 and 31 are moved in one process, so the number of processes required to move the empty needles is reduced. Unlike this example, the stitch rows 11 and the stitch rows 31 may be moved at different times.

[0036] In step S9, the back needle bed BB is racked three pitches to the left, and the new empty needle area 5W and the new empty needle area 5Y are positioned opposite the stitch rows 11 and 31, respectively. In step S9, the stitch rows 11 and 31, which are diagonally opposite each other across the joint 6, are moved to the new empty needle area 5W and the new empty needle area 5Y, respectively. Furthermore, in step S9, the stitch rows 21 and 41, which are diagonally opposite each other across the joint 6, are moved to the empty needle area formed by the movement of the stitch row 31 and the empty needle area formed by the movement of the stitch row 11, respectively.

[0037] In step S10, the rear needle bed BB is racked three pitches to the right, the stitch row 21 is moved to the front needle bed FB, and the stitch row 41 is moved to the rear needle bed BB. As a result, the new empty needle areas 5W, 5X, 5Y, and 5Z move three pitches each in the direction away from the joining portion 6.

[0038] By repeating the same knitting as in step S8 to step S10, the new empty needle areas 5W, 5X, 5Y, 5Z move to the outside of the knitting range of the right tubular portion 8 and the left tubular portion 9, and no empty needles exist within the knitting range. By knitting the double-stranded body 75 continuously in the wale direction of the right tubular portion 8 and the left tubular portion 9 from this state, the right tubular portion 8 and the left tubular portion 9 are joined together. In addition, because the double-stranded body 75 is knitted with full needles, the stitches of the double-stranded body 75 do not become coarse.

[0039] If the number of empty needles in each of the new empty needle areas 5W, 5X, 5Y, and 5Z is 1 or 2, the twin trunk 75 may be knitted without knitting as shown in Fig. 3. If the number of empty needles is small, the stitches of the twin trunk 75 are less likely to become coarse.

[0040] <Embodiment 2> In the second embodiment, a knitting example in which empty needles are distributed within the knitting ranges of the right tubular portion 8 and the left tubular portion 9 will be described with reference to Fig. 4. For ease of explanation, Fig. 4 shows the number of stitches in the right tubular portion 8 and the left tubular portion 9 to be greater than those in Figs. 2 and 3.

[0041] If the number of stitches in the right tubular portion 8 and the left tubular portion 9 is large, the number of knitting steps for removing empty needles from the knitting ranges of the right tubular portion 8 and the left tubular portion 9 increases. In the knitting of this example shown in step S20 of FIG. 4, after the joining portion 6 is formed, each of the empty needles constituting the new empty needle areas 5W, 5X, 5Y, and 5Z is distributed within the knitting ranges of the right tubular portion 8 and the left tubular portion 9. In this case, there is no need to remove empty needles from the knitting ranges of the right tubular portion 8 and the left tubular portion 9, and the number of knitting steps is dramatically reduced accordingly. The presence of empty needles within the knitting ranges may cause the stitches of the parts corresponding to the empty needles in the double body 75 continuing in the wale direction of the right tubular portion 8 and the left tubular portion 9 to become somewhat coarse, but the appearance and function of the glove 7 are hardly impaired.

[0042] <Embodiment 3> In the third embodiment, a knitting example in which the number of empty needles in the initial empty needle area 5F on the front needle bed FB is different from the number of empty needles in the initial empty needle area 5B on the back needle bed BB will be described with reference to FIG.

[0043] As shown in step S30 in Fig. 5, in this example, the back right stitch row 90B and the back left stitch row 80B each have three stitches, and the front right stitch row 90F and the front left stitch row 80F each have two stitches. The right tubular portion 8 and the left tubular portion 9 are knitted so that the initial empty needle area 5F is composed of four empty needles, and the initial empty needle area 5B is composed of three empty needles. From this state, the back right stitch row 90B is the first stitch row 1, the back left stitch row 80B is the second stitch row 2, the front right stitch row 90F is the third stitch row 3, and the front left stitch row 80F is the fourth stitch row 4, and joining of the right tubular portion 8 and the left tubular portion 9 begins.

[0044] In step S30, the first stitch row 1 and the second stitch row 2 are moved to the initial empty needle area 5B via the initial empty needle area 5F. More specifically, the four stitches consisting of the first stitch row 1 and the stitch adjacent to its left are moved three pitches to the right, and the second stitch row 2 is moved three pitches to the left. As a result, as shown in step S31, a joint 6 where the first stitch row 1 and the second stitch row 2 are overlapped is formed in the initial empty needle area 5B.

[0045] In step S31, the three stitches consisting of the third stitch row 3 and the stitch adjacent to its left are moved to the initial empty needle area 5F via the new empty needle area 5W formed in step S30. Furthermore, in step S31, the three stitches consisting of the fourth stitch row 4 and the stitch adjacent to its right are moved to the initial empty needle area 5F via the new empty needle area 5X formed in step S30.

[0046] As shown in step S32, a joint 6 is formed in the initial empty needle area 5F where the third stitch row 3 and the fourth stitch row 4 are overlapped. By moving three stitches including the third stitch row 3 in step S31, a new empty needle area 5Y is formed to the left of the three stitches. Also, by moving three stitches including the fourth stitch row 4 in step S31, a new empty needle area 5Z is formed to the right of the three stitches. Here, by moving the stitch to the left of the first stitch row 1 in addition to the first stitch row 1 in step S30, the relative arrangement of the new empty needle areas 5W, 5X, 5Y, 5Z becomes the same as that of the first embodiment. Therefore, after step S32, the new empty needle areas 5W, 5X, 5Y, 5Z can be efficiently moved to the outside of the knitting range of the right tube portion 8 and the left tube portion 9 by the same procedure as the knitting shown in FIG. 3 of the first embodiment.

[0047] In addition, the tubular knitted fabric of the present invention is not limited to gloves. For example, the tubular knitted fabric of the present invention may be footwear having finger pockets, knitwear such as trousers, or industrial materials such as covers. [Explanation of symbols]
