Abstract

PROBLEM TO BE SOLVED: To provide a new type of knitted loop-increasing method which can form a fine knitted loop-increasing point without hole formation on the loop-increasing point. SOLUTION: A knitted loop 10 for the missed stitch is formed on the needle adjacent to the needle connecting the knitted loop on the side edge of the first knitted fabric of missed stitch 10, then yarn-feeding opening is inverted to knit the second fabric, and the opening is inverted again to form the first fabric. Subsequently, a loop 10 of the missed stitch is formed on the needle before the needle formed the missed stitch 10 in the direction to which the yarn-feeding opening proceeds. The loop 10 of the missed stitch previously formed on the needle is transferred skipping the knitting yarn running between the loop of missed stitch of the other needle and the loop 12 on the side edge 12 of the knitted fabric connected to the needle in the opposing needle bed. The yarn-feeding opening is reversed to knit the second fabric thereby forming a knitted loop 12 of the following course to the loop of the missed stitch of the needle to which a loop is transferred to the needle in the opposing needle bed, and further, the feed opening is reversed. By knitting the first fabric, the loop 12 for the following knitting course can be formed on the loop 10 of' the other missed stitch.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention newly adds to a knitted fabric side end part in a process of knitting a knitted fabric formed by front and rear needle beds of a flat knitting machine as a tubular knitted fabric continuous at both ends thereof. The present invention relates to a knitting method for forming a widening stitch that increases a cylinder diameter by forming a stitch.

[0002]

2. Description of the Related Art Recently, the left and right sleeves and the body are knitted in advance as a tubular knitted fabric, and the knitting width is changed to form a knitted fabric having a desired shape. Various knitting methods for knitting a knitted fabric having a shape close to a finished product on a knitting machine by knitting while connecting are being studied. As a means for forming a knitted fabric into a desired shape, an additional stitch knitting for increasing the cylinder diameter is generally performed by forming a new stitch on an empty needle located outside the knitting width of the knitted fabric. There is. However, since the widening stitch is newly formed on the empty needle that does not hold the stitch, the stitch formed by the widening stitch has less tightness than the normal stitch because the stitches of the previous course do not exist. There is a problem that it becomes a stitch and a hole appears to be formed in the widening area. Therefore, the knitted fabric knitted on the knitting machine as a knitted fabric having a shape close to that of a finished product does not require the sewing work for joining the parts together, and the post-processing after the completion of knitting is significantly performed. Instead of omitting it, if a hole is formed at the place where the widening stitch is formed in order to increase the knitting width, it will appear on the surface of the knitted fabric as it is, and this will cause a decrease in commercial value.

As a method for solving the above-mentioned problems, the present applicant has previously filed Japanese Patent Publication No. 2-51810. In Japanese Patent Publication No. 3-51810, when knitting a tubular knitted fabric, the needle loops of the stitches forming the widening stitch are knitted so as to be in a twisted state in the knitting of the next course. There is disclosed a widening stitch knitting method in which the length of a stitch being stitched is shortened and a stitch adjacent to the widening stitch forming portion is pulled so that no hole is generated at the widening stitch forming portion.

[0004]

SUMMARY OF THE INVENTION The present invention is an improvement of the method disclosed in Japanese Patent Publication No. 3-51810 described above, in which a widening is formed by a relatively simple method and a hole is formed at the widening forming point. The purpose of the present invention is to provide a knitting method that does not occur, and in particular, it is possible to drastically increase the cylinder diameter and to form a widening stitch that can increase the degree of freedom in forming knitting. It is intended to disclose a method.

[0005]

A method for forming widening stitches in a tubular knitting machine according to the present invention is a flat knitted fabric having at least a pair of front and rear needle beds, and either or both needle beds are slidable from side to side. In the process of knitting fabric that is knitted in front and back using a machine as a tubular knitted fabric that is continuous at both ends, supply knitting yarn to the needle that holds the first knitted fabric. And forming a stitch for the next course, and supplying a knitting yarn to an empty needle adjacent to the needle that locks the side edge of the first knitted fabric to form an empty needle knit stitch. The second step of reversing the process and the yarn feeder, and supplying the knitting yarn to the needles of the needle bed holding the second knitted fabric to knit the stitches of the next course, reversing the yarn feeder, and While knitting the knitted fabric, the yarn is supplied from the needle in which the stitches of the empty needle knit are formed in the first step. Third forming the stitches of the empty needle knitting in the traveling direction of and the yarn is fed to the empty needles located in front
Step, the stitches of the empty needle knit formed in the first step are distributed between the stitches of the empty needle knit formed in the third step and the stitches which are the side edges of the first knitted fabric. The fourth step of transferring to the needle on the opposite needle bed over the existing knitting yarn,
Fifth step of reversing the yarn feeder and knitting the second knitted fabric to form the stitches of the next course on the stitches of the empty needle knit transferred to the needles on the opposite needle beds in the fourth step. And a sixth step of forming the stitches of the next course on the stitches of the empty needle knit formed in the third step by reversing the yarn feeder and knitting the first knitted fabric. According to this, once formed with the needle on the other needle bed, the increased stitch transferred to the opposite needle bed is twisted by half a turn, and the increased stitch becomes a short stitch. As a result, holes do not open in the widened area. In addition, one of the knitting yarns formed as the widening stitch and one of the knitting yarns of the other knitting yarn cross each other,
The surrounding stitches are attracted to the widening area, and holes are not formed in the widening area. Furthermore, since the knitted fabric in which a beautiful widening stitch portion is formed can be knitted by a simple knitting, the widening stitch can be formed without lowering the knitting efficiency.

In the fifth step, the stitches of the newly formed empty needle knit are transferred to the needles on the opposite needle beds, the front and rear needle beds are relatively moved, and then the needle beds are emptied again. The step of moving the stitch of the needle knit to an empty needle adjacent to the needle that locks the stitch at the side end of the first knitted fabric is included. According to the present invention, the widening stitch newly formed by the needle positioned outside the needle to which the widening stitch is to be locked is adjacent to the needle that has locked the stitch that has been the side end of the knitted fabric until then. Is moved to the needle.

FIG. 1 is a block diagram showing an embodiment of the present invention.
The case of knitting the sleeve member 1 as shown in FIG. 2 will be described in detail with reference to the drawings. In actual knitting, a large number of knitting needles are used for knitting, but here, for convenience of explanation, the number of needles used for knitting is set to be smaller than the actual number. In the knitting course diagram, the alphabets arranged above and below indicate the needles slidably mounted on the needle bed, the left and right arrows indicate the moving direction of the yarn feeder 1, and the up and down arrows indicate the transfer direction. The present invention includes at least a pair of front and rear needle beds, and a carriage (not shown) that slides left and right on the needle beds.
The knitting needle and the transfer cam provided on the knitting needle can be used for knitting with a general flat knitting machine configured to be capable of sliding back and forth.

First, when the present invention is carried out using a two-bed flat knitting machine having a pair of front and rear needle beds, the knitting course diagrams of FIGS. 2 and 3 and the widening stitches are formed according to the knitting course diagrams. This will be described with reference to FIG. 4, which is a loop diagram showing the widening stitch formation portion of the formed knitted fabric. FIG. 4 shows the place where the widening stitches are formed on the right side of the knitting course diagrams of FIGS.
FIG. 4 is a view in which the front side knitted fabric and the back side knitted fabric are developed to the left and right with the center as the center, and the alphabet indicates the needle used for forming the stitch and corresponds to FIGS. 2 and 3. In this embodiment, a two-bed flat knitting machine is used, and odd-numbered knitting needles (indicated by capital letters in the alphabet) on the front and rear needle beds are used for knitting the rear knitted fabric, and even-numbered needles (indicated by lowercase letters in the alphabet). ) Is used for knitting the front knitted fabric, and needles for knitting the front knitting fabric and needles for knitting the back knitting fabric are alternately arranged, and the needles on the opposite needle beds are used when transferring stitches. This allows transfer in the process of knitting in a tubular shape. Therefore, although it is possible to knit a knitted fabric including a knitting structure that is knitted using needles of both front and rear needle beds, such as rib knitting and links pattern,
In the following description, in order to make the description easy to understand, a case of a tubular knitted fabric knitted only with a plain knitting structure will be described as an example.

The actual knitting will be described. As shown in FIG. 2, in the course 1, the knitting yarns are supplied to the knitting needles b, c, d, e of the front bed FB to knit the front side knitted fabric X, and in the course 2, the yarn feeder 2 is reversed and the rear bed BB is formed. The knitting needles E, D, C and B are supplied with knitting yarns to knit the rear knitted fabric Y. The front side knitted fabric X and the rear side knitted fabric Y are produced by repeating the knitting shown in the course 1 and the course 2 by repeatedly supplying the knitting yarns to the knitting needles of the front and rear needle beds in an annular manner.
The cylindrical sleeve member 1 shown in FIG. Next, the knitting for forming the widening stitch is started. In the present embodiment, the front knitted fabric X and the rear knitted fabric Y each have one stitch at one end (for example, the right end) of the tubular knitted fabric. It is possible to form the widening stitches one by one and simultaneously form the widening stitches at both ends of the knitted fabric. Therefore, in the following description, a case will be described in which the front side knitted fabric X and the rear side knitted fabric Y are formed with widening stitches at both left and right ends to increase the cylinder diameter from the current 8th stitch to the 12th stitch.
As described above, in the present embodiment, since every other needle is used for knitting the front side knitted fabric X and the back side knitted fabric Y, the front side knitted fabric X has the needle a and the needle f of the front bed FB. A new stitch is formed on the back bed, and the rear knitted fabric Y forms a widening stitch on the back bed BB needles A and F.

First, in the course 3, the yarn feeder 2 is moved to the right, and the stitches of the front knitted fabric X whose side ends are located outside the rear knitted fabric Y are locked in the front bed FB. Knitting needle b
The front side knitted fabric X is knitted by supplying knitting yarns to c, d, and e, and the needle e that holds the stitch at the right end of the front side knitted fabric X is positioned forward in the traveling direction of the yarn feeder 2. A new stitch is formed by supplying the knitting yarn to the needle f of the front bed FB and hooking the knitting yarn. At this time, since the stitch of the previous course does not exist on the needle f, the newly formed stitch is in a state called the stitch 10 of the empty needle knit that is locked in the hook of the knitting needle. Next, in the course 4, while the yarn feeder 2 is being inverted, the knitting yarn is supplied to the needles E, D, C, B of the rear bed BB which holds the stitches of the rear knitted fabric Y and the rear knitted fabric is While knitting Y, the needle a of the rear bed BB, which is located in front in the traveling direction of the yarn feeder 2 of the needle B of the rear bed BB, which holds the stitch on the left side of the rear knitted fabric Y, Also supplies knitting yarn to newly form stitches of empty needle knit. Next, in the course 5, the yarn feeder 2 is reversed, and the knitting yarn is supplied to the needles b, c, d, and e of the front bed FB to form the stitches, and in the course 3, the stitches of the empty needle knit are formed. The knitting yarn is also supplied to the needle f of the front bed FB which is located in front of the needle F of the bed FB in the traveling direction of the yarn feeder 2 to form the stitch 11 of the empty needle knit. Next, in the course 6 of FIG. 3, the stitch 10 of the empty needle knit formed on the needle F of the front bed FB in the course 3 is transferred to the needle F of the rear bed BB. At this time, the stitch 10 of the empty needle knit that has been retained by the needle F has the knitting yarn 13 that extends between the stitch 12 that is retained by the needle e of the front bed FB and the stitch 11 of the needle f. Bed B beyond
It is transferred to the needle F of B. Further, in the above-mentioned course 4, the knitting yarn is supplied from the needle E located on the left side of the needle F of the front bed FB that lastly supplied the knitting yarn in the course 3.
Therefore, by transferring the stitch 10 of the empty needle knit locked to the needle F of the front bed FB to the needle F of the rear bed BB, the stitch of the empty needle knit locked to the needle F of the front bed FB is transferred. 10 is from the needle F of the front bed FB to the back bed BB
When the stitch is transferred to the needle F, the stitch is twisted by half a turn.

Next, in the course 7, the yarn feeder 2 is reversed, and the knitting yarn is supplied to the needles F, E, D, C and B of the rear bed BB to form stitches, and in the course 4, the empty needle knit is formed. An empty needle knit is supplied by supplying a knitting yarn to a needle A located forward in the traveling direction of the yarn feeder 2 of the needle a of the rear bed BB, which locks the stitch at the left end of the rear knitted fabric Y on which the stitch is formed. To form a stitch. At this time, by supplying the knitting yarn to the needle F of the rear bed BB to form the stitches of the next course, the stitch 10 of the empty needle knit transferred to the needle F of the rear bed BB in the course 6 becomes Since the needle is knocked over beyond the formed stitch 14, the normal stitch 14 is applied to the needle F of the rear bed BB.
Is formed. And in course 8, the needle a of the rear bed BB
By transferring the stitch of the empty needle knit that is locked to the needle a of the front bed FB, the knitting yarn that was locked to the needle a is engaged with the needle B of the rear bed BB as in the case of the course 6. The stitches are transferred to the needle a of the front bed FB in a state where the stitches are twisted half a turn over the knitting yarn crossing between the stopped stitch and the needle A of the rear bed BB. And in course 9, front bed FB
By supplying the knitting yarns to the needles a, b, c, d, e, and f of the above to form the stitches of the next course, the normal stitch 15 is formed on the needle f of the front bed FB, and the needle a is similarly formed. Ordinary stitches are also formed. Further on course 10, the needles FE of the rear bed BB
By supplying the knitting yarns to C, B, and A to form the stitches of the next course, the normal stitches are also formed on the needle A of the rear bed BB. As a result, new stitches are retained on the needles a and f of the front bed FB and the needles A and F of the rear bed BB, and the tubular diameter of the knitted fabric is increased by a total of 4 stitches compared to the state of course 1. Becomes

The knitted fabric in which the widening stitches are formed by the above knitting course is, as shown in FIG. 4, the stitch 10 of the empty needle knit transferred to the needle F of the rear bed BB, and the course 6 of the front bed FB. The knitting yarn 13 which crosses between the stitch 11 of the empty needle knit formed on the needle f and the stitch 12 formed by the needle e is in a crossed state. Therefore, the newly formed stitches are attracted to each other, and holes are prevented from being formed in the widening stitch portions. In addition, since the stitch 10 which is in a state of being half-twisted by transferring the stitches to the opposite needle bed after forming the stitches on one needle bed has a short stitch length, the stitches 11 and The stitch 14 is prevented from being lifted up, and a hole is not formed in the widening portion.

As shown in the above-described embodiment, in the courses 3 to 8 in which the knitting for forming the widening stitch is performed, the front knitted fabric X and the back knitted fabric Y are each knitted in two courses. It is carried out. As described above, in the widening stitch knitting method of the present invention, when the widening stitch is formed at either one of the left and right ends of the knitted fabric, the front side knitted fabric X1 and the back side are formed while the stitches for two courses are formed. A total of two stitches of the knitted fabric Y1 can be performed, and when the stitches are formed in parallel at both ends of the knitted fabric, the front knitted fabric X2 and the rear knitted fabric Y2 are added in total 4 It is possible to perform eye widening.
Therefore, the cylinder diameter can be rapidly increased by forming the widening stitches in parallel at both ends of the knitted fabric, and the degree of freedom in forming the knitted fabric is increased.

In the above embodiment, the case of knitting using a two-bed flat knitting machine having a pair of front and rear needle beds has been described as an example. However, the present invention is a pair of front and rear needle beds. A so-called four-bed flat knitting machine having an upper bed can also be knitted, and knitting course diagrams in that case are shown in FIGS. 5 and 6 (course 1 in FIG. 5 to course 10 in FIG. 6 is shown in FIG. 2). (For the course 3 and subsequent courses, FD indicates the lower front bed, FU indicates the upper front bed, BD indicates the lower rear bed, and BU indicates the upper rear bed.) In a four-bed flat knitting machine, by using the needles of the upper bed facing each other at the time of transfer, between the needles used to form the stitches as in the case of knitting with a two-bed flat knitting machine. It is possible to knit a knitted fabric including a knitting structure such as rib knitting and links pattern without arranging a transfer needle, but in the present embodiment, in order to facilitate the explanation, knitting is performed only with a flat knitting structure. Since the case of the knitted fabric is described as an example, the upper needle bed is not used for knitting in FIGS. 5 and 6. In the case of the two-bed flat knitting machine described in FIGS. 2 and 3, for example, in the course 5 of FIG. 2, the needle F of the front bed FB is a needle for knitting the rear knitted fabric, and the adjacent needles are While f is a needle for knitting the front knitted fabric, in the case of the four-bed flat knitting machine, the needle H of the front bed FB in the course 3 of FIG. 5 corresponding to the course 5 of FIG. The adjacent needle I is also a needle for knitting the front knitted fabric. As described above, in the case of the four-bed flat knitting machine, one of the stitches newly formed at the side end of the knitted fabric uses a needle located outside the needle for locking the stitch. Formed. Therefore, FIG.
The stitches formed outside the needles to be locked in the courses 6 to 8 are moved to appropriate positions. In other words, after transferring the stitches of the empty needle knit that are locked to the needles I of the lower front bed in the course 6 to the needles I of the lower rear bed facing each other and after racking the rear bed to the left by one pitch for the course 7 , The stitch of the empty needle knit that is locked to the needle of the lower rear bed is transferred to the needle H adjacent to the needle G of the front lower bed that locks the stitch at the side end of the front knitted fabric X. Similarly, in course 7, after transferring the stitch of the empty needle knit, which is locked to the needle B of the rear lower bed, to the needle A of the front lower bed, and in course 8, racking the rear bed further leftward by 1 pitch of needles. The transfer of the stitch is completed by transferring the stitch of the empty needle knit to the needle C of the rear lower bed. The knitted fabric knitted according to the knitting course diagrams shown in FIG. 5 and FIG.
The knitting structure is the same as when knitting is performed using the two-bed flat knitting machine shown in FIG.

The above description of the two-bed flat knitting machine is based on the premise that it can be carried out even when knitting a knitted fabric including a knitting structure such as rib knitting and links pattern. As shown in FIG. 2 and FIG. 3, every other needle is used for forming stitches, and a needle for transferring stitches is arranged between the needles used for forming stitches for knitting. When knitting only by the flat knitting structure, from the knitting course diagrams for the four-bed flat knitting machine shown in FIGS. 5 and 6, the front upper bed FU and the rear upper bed BU are shown.
The knitting is the same as that of the case in which the knitting is omitted, and knitting can be performed in a state called all needles without disposing a transfer needle between the needles used to form the stitches.

[0016]

As described above, in the widening stitch forming method in the tubular knitting of the present invention, one of the newly formed stitches is once formed with the needle on the other needle bed,
The newly formed stitch is interlocked with another newly formed stitch formed by the needle located forward in the traveling direction of the yarn feeder on the same needle bed as the stitch and the needle of the opposite needle bed. The knitting yarn extending between the stitches at the side edges of the stopped knitted fabric is crossed over and transferred to a needle on the opposite needle bed. Therefore, the stitches that are once formed by the needles on the other needle bed and transferred to the opposing needle bed are twisted by half a turn, and the stitches that have been increased become stitches of short length. Never opens. In addition, one stitch of the stitches formed as the widening stitch and one knitting yarn of the knitting yarns of the other stitch cross each other, and the surrounding stitches are attracted to the widening stitch formation portion. Therefore, no hole is formed in the widening area. Furthermore, since the knitted fabric in which a beautiful widening stitch portion is formed can be knitted by a simple knitting, the knitting efficiency is not reduced. Further, when the widening stitches are performed in parallel at both ends of the tubular knitted fabric, the tubular diameter can be rapidly increased, and the degree of freedom in forming the knitted fabric is increased.
