Description

  The present invention provides a yarn processing unit in which a yarn processing unit is provided in a knitting yarn used for knitting a knitted fabric with a flat knitting machine, and a property such as a color is switched in a knitted state in the knitted fabric. The present invention relates to a knitted fabric, a processing method thereof, and a design apparatus.

  Conventionally, in a flat knitting machine, a plurality of types of yarn feeders are used properly and a plurality of types of knitting yarns having different colors are switched to knit a knitted fabric. However, the type of knitting yarn that can be used is limited by the number of yarn feeders. If a yarn processing part is provided in the middle of the knitting yarn to be supplied from the same yarn feeder, and switching such as connecting different knitting yarns is performed, a plurality of types of knitting yarns are sequentially supplied from one yarn feeder. be able to. That is, the number of usable knitting yarns is not limited by the number of yarn feeders, and it becomes possible to knit a knitted fabric using many colors. When switching the knitting yarn by providing a yarn processing part in the middle of the knitting yarn, calculate the amount of knitting yarn used by knitting and make sure that the yarn processing part reaches the position where the knitting yarn is switched on the knitted fabric in advance. The timing for performing yarn processing is adjusted (for example, see Patent Document 1). The yarn processing portion remains knitted into the knitted fabric. It is described that the process of setting the position of the yarn processing unit is performed in the control device of the flat knitting machine. It is also known that the processing function provided in such a flat knitting machine can be provided on the design device side that creates knitting data of the knitted fabric.

When knitting a multicolored striped knitted fabric by using a plurality of yarn feeders and switching a plurality of types of knitting yarns every predetermined course, for example, the knitting yarn is used next from the switching point of each knitting yarn. A yarn is formed by the time. Since this transition yarn is generated outside the knitting width, it is cut. A processing method is also disclosed in which a knitting yarn surplus portion generated by cutting is drawn into a knitted fabric by extending the knitted fabric (see, for example, Patent Document 2).
Japanese Patent No. 2816784 Japanese Patent No. 3839496

  The yarn processing section as in Patent Document 1 is mechanically formed by a splicing device such as a knotter that connects and connects knitting yarns, or a splicer that connects and connects knitting yarns once. The position where the yarn processing portion is provided on the knitting yarn can be theoretically obtained by using the data for knitting the knitted fabric and calculating back the amount of knitting yarn used from the position where the knitting yarn is switched on the knitting ground. If the position of the yarn processing portion coincides with the position where the knitting yarn is switched on the knitting ground, the knitting yarn should be able to be switched only by knitting. However, even if the yarn processing portion is knitted at the knitting yarn switching position on the knitting ground, the yarn splicing portion that is mechanically formed by the yarn splicing device increases the thickness of the knitting yarn, and the knot or yarn splicing A surplus part also arises. When a knitted fabric including such a yarn linking portion is used as a knitted fabric, the knitted fabric may impair the aesthetic appearance. Even when the yarn connecting portion does not come out on the surface of the knitted fabric and comes out on the back side, there is a possibility that the wearer may feel a sense of incongruity when touched.

  Further, as the yarn processing, the same knitting yarn can be dyed to change the color. However, in dyeing, color bleeding tends to occur at the color switching position, and even if the yarn processing portion is accurately knitted at the color switching position of the knitted fabric, the appearance may be impaired.

  Furthermore, the occurrence of an error between the position of the yarn processing portion on the knitting yarn and the switching position of the knitting yarn on the knitting ground is unavoidable in reality. For this reason, in consideration of the error range, it is necessary to perform a process of knitting excess knitting yarn into the knitted fabric in the vicinity of the yarn processing portion of the knitting yarn so that it cannot be seen from the surface of the knitted fabric. However, the yarn processing portion mechanically formed by yarn joining or the like becomes thick or has a surplus end portion. Therefore, when knitting with a knitting needle, resistance is large, and there is a risk of catching or yarn breakage.

  If the yarn processing portion is included in the portion to be cut and removed as the transition yarn outside the knitting width as in Patent Document 2, the yarn processing portion can be removed from the knitted fabric. However, when the yarn processing portion is provided to switch the color of the knitting yarn of the striped knitted fabric, the knitting yarn supplied from the same yarn feeder is switched to knitting the next next pattern section. Therefore, when the knitting yarn is switched at the yarn processing section, there is no section that becomes the transition yarn outside the knitting width.

  An object of the present invention is to provide a knitted fabric having a yarn processing portion, a processing method therefor, and a design device so that the yarn processing portion can be easily removed to improve the quality of the knitted fabric.

According to the present invention, the properties of the knitting yarn supplied from the same yarn feeder for knitting the knitted fabric can be switched based on the data for knitting the knitted fabric at the position on the knitted fabric corresponding to the data.

After forming at least one of the unlocking portions to be applied, knitting of the knitted fabric is continued,
After the knitting of the knitted fabric, the yarn processing section processing method is characterized in that the knitting yarn in the transition section including the yarn processing section is cut and removed from the knitted fabric.

  In the present invention, the unwinding treatment is performed by tacking the knitting yarn to the knitted fabric at a plurality of locations.

In the present invention, as the knitted fabric, knitted fabrics knitted on the front and back needle beds of the flat knitting machine are connected on both sides of the knitting width and knitted into a tubular shape,
Forming the transition section on the outside of the tubular knitted fabric;
The knitting yarn of the transition section remaining after the cutting is drawn into the tubular knitted fabric and absorbed.

  In the present invention, the locking at the locking portion is performed by tucking the knitting yarn into a stitch forming the knitted fabric.

  Further, in the present invention, the locking at the locking portion is performed by winding the knitting yarn around a knitting forming the knitted fabric.

  Further, in the present invention, the locking at the locking portion is a knitting yarn near the folding position where the knitting yarn in the transition section reciprocates, and hooks the knitting needles that are not locking the stitches of the knitted fabric, The knitting yarn in the transition section is passed between the one surface side and the other surface side of the knitted fabric, and then it is performed by removing the hooks.

  Further, in the present invention, the knitting yarn is provided with a plurality of yarn processing portions at intervals, and the transition sections formed on different knitting courses including each yarn processing portion are arranged along a virtual straight line. It is characterized by that.

Furthermore, the present invention provides a knitted fabric design device for generating knitting data for knitting a knitted fabric with a flat knitting machine.
For the knitting yarn supplied from the same yarn feeder for knitting the knitted fabric, the knitting yarn properties are switched at the position on the knitted fabric corresponding to the data based on the data for knitting the knitted fabric. To process the yarn processing part while knitting the ground,

  According to the present invention, the knitting yarn supplied from the same yarn feeder for knitting the knitted fabric is knitted to the knitted fabric having a yarn processing portion for switching to a knitting yarn having a different property during knitting. It includes at least one of a stop part or a release part. The transition section is formed so as to reciprocate without being knitted into the knitted fabric with the knitting yarn in the section before and after the yarn processing section. By cutting the knitting yarn in the transition section including the yarn processing portion, the yarn processing portion can be easily removed from the knitted fabric. If the yarn processing portion is removed from the knitted fabric, the yarn processing portion will not lose its appearance or give a feeling of strangeness when the knitted fabric is worn, and the quality of the knitted fabric can be improved. If a part of the knitting yarn that reciprocates in the crossing section is locked to the knitted fabric by the locking portion, the knitting yarn in the crossing section is unlikely to hang down from the knitted fabric. Providing the unwinding portion on the knitted fabric side of the portion where the knitting yarn transitions to the crossover section can prevent the knitted fabric from being unwound even if the knitting yarn in the crossover section including the yarn processing section is cut and removed. .

  Further, according to the present invention, the unlocking process of the unlocking portion is performed by tucking the knitting yarn at a plurality of locations on the knitted fabric, so that the influence on the appearance and elongation of the knitted fabric can be reduced.

  According to the present invention, the transition section is exposed to the outside after the knitted fabric of the tubular knitted fabric, and the process of cutting the transition section can be easily performed.

  Further, according to the present invention, since the transition sections formed on different knitting courses are arranged along a virtual straight line, when cutting the transition section after knitting of the knitted fabric, the cutter is moved along the straight line. Thus, the processing can be performed efficiently.

  Furthermore, according to the present invention, before the knitting yarn is switched at the yarn processing portion, the yarn processing portion can be included in the transition section formed so that the knitting yarn is reciprocated without being knitted into the knitted fabric. After knitting of the knitted fabric, the knitting yarn in the transition section including the yarn processed portion is cut and removed from the knitted fabric, so problems such as the appearance when the yarn processed portion remains on the knitted fabric and the feeling of strangeness when worn are eliminated, The quality of the knitted fabric can be improved. Even if the yarn processing portion is not knitted into the knitted fabric with the knitting needle, the error in the vicinity of the yarn processing portion can be absorbed, and the nature of the knitting yarn can be switched at a position according to the knitting data on the knitting ground. If the locking portion is formed, the knitting yarn in the transition section including the yarn processing portion is stable and can be easily cut. By forming the unclamping portion, it is possible to prevent the knitted fabric from being unraveled even if the knitting yarn in the transition section including the yarn processing portion is cut and removed.

  Further, according to the present invention, since the unblocking process is performed by tacking a plurality of places on the knitted fabric, the process is easy and the influence on the appearance and elongation of the knitted fabric can be reduced.

  Further, according to the present invention, since the transition section that is reciprocated without being knitted into the knitted fabric is formed outside the tubular knitted fabric, the knitting yarn can be easily cut after the knitted fabric. Since the cut knitting yarn is drawn into the tubular knitted fabric and absorbed, the end yarn can be prevented from being seen from the outside of the tubular knitted fabric.

  Further, according to the present invention, the knitting yarn in the transition section is locked to the knitted fabric by tucking with the knitting yarn to the stitch forming the knitted fabric. We can keep weaving to the ground to a minimum. Even in a case where the yarn processing portion is applied to the tacked portion, the load for drawing the knitting yarn can be reduced.

  Further, according to the present invention, the knitting yarn in the transition section is locked to the knitted fabric by winding the knitting yarn around the knitting fabric forming the knitted fabric. Can be stopped.

  Further, according to the present invention, after the knitting yarn in the transition section is locked to the knitted fabric, the knitting yarn in the vicinity of the turn-back position is applied to the knitted fabric, and then the knitting yarn in the transition section is connected to one surface side and the other surface of the knitted fabric. Pass alternately between the sides. Since the stitches are removed after passing the knitting yarn through the knitted fabric, the portion passing through the knitted fabric can be easily removed after the transition yarn is cut.

  Further, according to the present invention, the transition sections formed by different knitting courses are arranged along a virtual straight line. Therefore, when the transition section including the yarn processing portion is cut after knitting of the knitted fabric, the cutting operation is performed in a straight line. Can be performed efficiently along.

  Furthermore, according to the present invention, a yarn processing portion is provided in the knitting yarn based on data for knitting the knitted fabric, and the knitting yarn before and after the yarn processing portion is not knitted into the knitted fabric, and can be easily processed by post-processing. The knitting data for enabling cutting can be generated so that the flat knitting machine is executed.

Explanation of symbols

1,11,21,31 Knitted fabric having yarn processing portion 2 Yarn processing portion 3 Border pattern 4 Crossover yarn 4a Forward crossover section 4b Return crossover section 5, 5a, 5b Tack section 6, 16, 26 Locking section 40 Design equipment

  FIG. 1 shows a schematic configuration of a knitted fabric 1 having a yarn processing portion as one embodiment of the present invention. A knitted fabric 1 having a yarn processing section is a flat knitting machine having needle beds opposed to each other, for example, and is a tubular knitted fabric in which a sweater or the like is knitted without sewing. Different knitting yarns are joined in advance by a yarn joining device. And a thread processing portion 2 that can be switched. A knitted fabric 1 having a yarn processing portion has a multicolor stripe-shaped border pattern 3 and is provided with an A color region 3a, a B color region 3b, a C color region 3c, and the like. The thread processing portion 2 is provided in the vicinity of the position where the border pattern 3 is switched between the A color area 3a and the B color area 3b, for example. In the knitted fabric 1 having the yarn processing portion according to the present embodiment, the knitting yarn is drawn out from the surface of the knitted fabric to the outside of the knitted fabric as the cross yarn 4, and the yarn processing portion 2 is included in the range of the drawn out cross yarn 4. . For this purpose, a knitting yarn having a length that absorbs an error in the position of the yarn processing unit 2 may be drawn out as a transition yarn 4 that is not knitted into the knitted fabric.

  The crossover yarn 4 is folded back at the tip so as to reciprocate between the forward crossover section 4a and the return crossover section 4b. Tack sections 5a and 5b are respectively provided in the knitted fabric at a portion where the crossover yarn 4 of the forward crossover section 4a is pulled out so as not to be knitted into the knitted fabric and a portion where the crossover yarn 4 of the crossover section 4b of the return path is returned. . As will be described later, in order to remove the yarn processing portion 2, the transition yarn 4 is cut and removed in a post-process after knitting of the knitted fabric 1 having the yarn processing portion. In the tack sections 5a and 5b, since the knitting yarn is tacked to the stitches of the knitted fabric at a plurality of locations, even if the transition yarn 4 is cut, the unraveling does not easily proceed. Similar unlocking can be performed not only by tucking at a plurality of locations but also by knotting. Details of knotting are disclosed in, for example, Japanese Patent Laid-Open No. 8-188842. However, the influence on the appearance and properties of the knitted fabric is preferable because the tack sections 5a and 5b are smaller than knotting. In addition, when showing both the tack sections 5a and 5b, it describes as the tack section 5. When the knitted fabrics are knitted with the front and back needle beds as in the knitted fabric 1 having the yarn processing portion, for example, the tack section 5a for pulling out the forward crossing section 4a is provided on the knitted fabric knitted with the front needle bed, If the tack section 5b to which the transition section 4b returns is provided on the knitted fabric knitted on the rear needle bed, the influence of the tack section 5 is more preferable. In the tack section 5, the knitting yarn is tucked to a plurality of knitting needles at intervals rather than continuous knitting needles.

  The forward crossover section 4 a and the return crossover section 4 b are formed by folding the leading end of the crossover thread 4. The vicinity of the tip of the crossover yarn 4 is locked to the knitted fabric as a locking portion 6. For example, a tuck can be used as the knitting operation for locking by the locking portion 6. Since the yarn processing portion 2 exists between the forward crossover section 4a and the return crossover section 4b, there is a possibility that the yarn processing section 2 may be caught on the locking portion 6. When the color is changed by dyeing or the like in the yarn processing portion 2, even if it is hooked on the locking portion 6, it can be knitted in the same manner as the knitting yarn of other portions. Even if the yarn processing portion 2 is connected to the yarn, if it is a tack, the amount of the knitting yarn drawn is less than that of the knit, so that the yarn processing portion 2 can also be knitted and locked in the knitted fabric. However, the knitting can be performed more reliably if the yarn processing portion 2 is not engaged with the locking portion 6 when the thickness of the knitting yarn or the like is increased by performing yarn splicing or the like.

  In the knitted fabric having the yarn processing portion of FIG. 1, the color is switched at the knitting end on the right side of the drawing. The length of the crossover yarn 4 is set by returning the knitting yarn from the knitting end to the inside of the knitting width so that the yarn processing section 2 exists in the forward crossover section 4a. You may set so that the thread process part 2 may exist in the crossover section 4b of a return path. When a plurality of yarn processing portions 2 are provided, the positions at which the transition yarns 4 are drawn out along the virtual straight lines 7a, 7b, and 7c in different knitting courses for processing each yarn processing portion 2 are set. As a result, when the crossover yarn 4 is cut, a plurality of crossover yarns 4 are arranged in a direction in which a cutting tool such as stagnation is applied. By moving the cutting tool along the straight lines 7a, 7b, 7c, it is possible to efficiently cut a plurality of locations.

  The knitted fabric 1 of the border pattern 3 as shown in FIG. 1 can be knitted by assigning a yarn feeder for each knitting yarn of each color if the number of colors to be used is not large. In this case, if the same color region exists at a distant position, a cross yarn is generated at the knitting end of the knitted fabric 1 along the surface of the intermediate region in the longitudinal direction of the drawing. In the example disclosed in Patent Document 2, such transition yarns are generated at a plurality of locations in the vertical direction in the figure. In order to cut the crossover yarn, a tool such as a shave must be applied in a direction perpendicular to the paper surface. Since the direction in which the tool is applied and the direction in which the transition yarns to be processed are arranged are perpendicular, the transition yarns must be cut several times individually. Further, when a long transition yarn is pulled out to the side end of the knitted fabric in a short section, the transition yarn must be cut in a state of hanging from the side end, so that the cutting efficiency is further deteriorated.

  FIG. 2 shows a schematic procedure for knitting a knitted fabric 1 having a yarn processing portion as shown in FIG. 1 and processing the yarn processing portion 2. On the left side, the steps of the procedure sequence are shown numerically.

  In step 1, the A color region 3a of the border pattern 3 is knitted in a cylindrical shape while circulating the knitting yarn around the front and back needle beds facing each other with the center line 8 of the tooth mouth interposed therebetween. In step 2, on the outside of the tubular knitted fabric, the transition yarn 4 of the forward transition section 4a in which the tack section 5a is formed on the knitted fabric knitted on the front needle bed is not knitted into the knitted fabric. Draw along the surface. The leading end pulled out so as to include the yarn processing portion 2 is locked to the knitted fabric by the locking portion 6, the crossover yarn 4 is folded back, and the knitting yarn is returned to the inside of the tubular knitted fabric from the crossover section 4 b of the return path. The knitting yarn in the return crossing section 4b returning to the knitted fabric is switched to the B-colored knitting yarn by the yarn processing section 2, and after forming the tack section 5b on the knitted fabric knitted on the rear needle bed, the step 3 The knitting of the B color area 3b is continued. By such knitting yarn switching, a color switching portion 3x is generated at the right end of the tubular knitted fabric.

  When the knitted fabric 1 having the yarn processing portion as shown in FIG. 1 is knitted, a post-process for cutting the transition yarn 4 in step 4 is performed. The transition yarn 4 is cut at a position 7 closer to the tack section 5 than the yarn processing portion 2. Since the cut portion protrudes outside the knitted fabric along the surface of the tubular knitted fabric, the cutting operation can be easily performed. Furthermore, if a plurality of cutting positions 7 are arranged along the straight lines 7a, 7b, and 7c as shown in FIG. 1, a plurality of positions can be cut efficiently. After cutting, as shown as step 5, the front end side of the transition yarn 4 including the yarn processing portion 2 is removed from the knitted fabric. Since only the crossover yarn 4 is locked to the knitted fabric by the tacking portion 6, if the pulling from the side including the yarn processing portion 2 in the forward crossover section 4 a or the return crossover section 4 b, The crossover yarn 4 that is not knitted in the knitted fabric can be easily pulled out. The end yarn remaining on the tack section 5 side after cutting can be made invisible from the outside by extending the knitted fabric in step 6 and drawing it into the inside of the tubular knitted fabric. Since both of the tack sections 5a and 5b are subjected to the unwinding treatment, the knitted fabric is prevented from being unwound from the end yarn.

  3 to 8 show a schematic procedure for knitting a knitted fabric 1 having a yarn processing section as shown in FIG. 1 with a four-bed flat knitting machine having front and rear two-stage needle beds. If the needle knitting is performed, the knitted fabric 1 having the yarn processing portion can be knitted by the same procedure even in a two-bed flat knitting machine having a single upper and lower needle bed.

  In each figure, the intermediate mesh indicates the state of the knitting needle for each needle bed. The lower and upper stages of the front needle bed are indicated by FD and FU, and the lower and upper stages of the rear needle bed are indicated by BD and BU. The position of the knitting needle on the front needle bed is indicated by A to O, the position of the knitting needle on the rear needle bed is indicated by a to o for the position of the stitches. The positions of the meshes correspond to the positions A to O and a to o of the knitting needles. However, the number of knitting needles is for convenience of explanation, and more knitting needles are usually used when actually knitting the knitted fabric. Circles shown in the squares indicate stitches. The V mark indicates a tack. When a stitch is newly formed by knit or when a new tack is performed, it is indicated by a thick line. The diagonal lines indicate the A-color knitting yarns with a lower left angle and the B-color knitting yarns with a lower right angle. An arrow in the mesh indicates a state where the stitch is transferred to the opposite needle bed.

  The left side of the cell indicates the numerical value of the step corresponding to the procedure. However, the numerical value of the step does not necessarily correspond to the stroke of the carriage, for example. In some cases, multiple strokes of the carriage are associated in one step. In addition, when a plurality of cam systems for driving the knitting needles are mounted on the carriage, one stroke of the carriage may correspond to a plurality of steps. The right side of the mesh indicates the moving direction of the yarn feeder for feeding the knitting yarn and knitting or forming the transition yarn.

  3 and 4 show a basic knitting procedure. In step 1 of FIG. 3, the course on the front needle bed side of the tubular knitted fabric is knitted in the left direction with the A-color knitting yarn. Next, in Step 2, the course on the rear needle bed side is knitted in the right direction with the A color knitting yarn. Such cylindrical knitting is repeated, and in the last course, knitting is not performed with the final knitting needle o. In this way, the A color area 3a in FIG. 1 is knitted except the final stitch. In step 3, the stitches locked to the knitting needles E to H of the FD corresponding to the section in which the crossover yarn 4 of FIG. 1 is pulled out are transferred to the BU knitting needles e to h by transfer. In the next step 4, the A color knitting yarn is tacked to the knitting needles N, L, and J of the FD to form the tack section 5a of FIG. From the vicinity of the position of the knitting needle H to the position of the knitting needle D, the knitting needle H is pulled out without being knitted into the knitted fabric to form the forward crossing section 4a of FIG. 1 is formed by tucking the leading end of the crossover yarn 4 to the knitting needle D that locks the stitches. Next, in step 5, the knitting yarn tucked onto the knitting needle D is folded back, and the crossing section 4b of the return path in FIG. 1 is formed without knitting into the knitted fabric up to the BD knitting needle j, and the knitting needles j, l, n of the BD are tacked. Thus, the tack section 5b of FIG. 1 is formed. The knitting yarns forming the return crossing section 4b and the tack section 5b are switched to B-color knitting yarns in the yarn processing section 2 of FIG.

  Next, in Step 6 of FIG. 4, the stitches locked to the knitting needles e to h of the BU are returned to the knitting needles E to H of the FD. The transition yarn 4 in this section is pushed out and goes out of the tubular knitted fabric. In step 7, stitches are formed on the final knitting needle o of the BD with B-colored knitting yarn. However, the yarn feeding direction is the left direction opposite to the right direction in which the A-colored knitting yarn is fed to the knitting needles a to n in Step 2. In step 8, the yarn feeder is kicked back to form a twist in the knitting needle o, and the yarn feeder is taken out of the knitting width so as to be on the right side of the knitting needle o. Without forming such a twisted stitch, it is also possible to perform the circular knitting by knitting the front knitted fabric in the left direction in FD and the rear knitted fabric in the right direction in BD. However, the stitch formed on the last knitting needle o of the BD is shifted by one course from the stitch formed on the first knitting needle O of the opposing FD. In order to prevent the difference in level when the knitting yarn is switched from the A color to the B color between the knitting needles O and o, it is preferable to perform processing as shown in Step 7 to Step 8.

  In step 9, the course on the front needle bed side of the tubular knitted fabric is knitted in the left direction with the knitting yarn switched to the B color. In step 10, the rear needle bed side course is knitted in the right direction. Hereinafter, when the knitting yarn is switched from the B color to the A color or another color, the same procedure is repeated to knit a tubular knitted fabric having a multicolor pattern of the border pattern 3 as shown in FIG. can do.

  FIG. 5 shows a main part of a procedure for knitting a knitted fabric in which the yarn processed portion 2 can be removed in a subsequent process in the same manner as the knitted fabric 1 having the yarn processed portion of FIG. Steps 1 to 4 are the same as those in FIG. In step 5, a return tack section 5b is also formed on the front needle bed side. However, when the knitting needles J, L, and N of the FD are tacked in the forward tack section 5a, the knitting needles I, K, and M are tacked in the backward tack section 5b. Thus, it is preferable to avoid overlapping of knitting needles to be tackled. This is because if the knitting needles to be tacked overlap, the flexibility of the knitted fabric may be impaired. The transfer at step 6 is performed in the same manner as at step 6 in FIG. Hereinafter, steps 7 to 10 may be performed in the same manner as in FIG.

  As shown in FIG. 5, the forward tack section 5a and the return tack section 5b may be formed on the same knitted fabric. The yarn processing section 2 can be removed by applying the present invention even to a single knitted fabric that is the subject of Patent Document 1 instead of a tubular knitted fabric. The switching of the knitting yarn by forming the yarn processing portion 2 is not only the border pattern 3 in which the knitting yarn is switched for each course as shown in FIG. 1, but also the diamond of the intarsia pattern knitted fabric as shown in FIG. A pattern in which the knitting yarn is switched during the course, such as a shape pattern, may be used.

  FIG. 6 shows a procedure for pulling out the transition yarn 4 without performing transfer at Step 3 in FIG. That is, after step 1 and step 2 in FIG. In step 4, the knitting yarn is tucked to the knitting needles N, L, and J of the FD, and then formed as the transition yarn 4, and the tip is locked to the knitting needle D of the FD by tucking. In step 5, the crossover yarn 4 is folded back, and the knitting yarn returning from the crossover section 4b on the return path is tucked to the knitting needles j, l, and n of the BD. The stitches are not returned as in step 6 of FIG. 4, and the same procedure as in steps 7 to 10 is performed. Since the stitches E to H are not transferred, the transition yarn 4 stays in the mouth of the needle bed and stays inside the knitted fabric knitted by the front and back needle beds. If the tubular knitted fabric is turned over after the knitting is completed, the transition yarn 4 can be easily cut and removed as in the examples of FIGS.

  7, as in FIG. 6, the transfer yarn 4 is formed inside the tubular knitted fabric without performing the transfer in Step 3 of FIG. 3, and the tack section is the same as in FIG. 5. The example formed in a knitted fabric is shown. Steps 1 and 2 are the same as in FIG. The transition yarn 4 is formed in step 4 in the same manner as in step 4 of FIG. However, the tack section 5b by the yarn returning from the return crossing section 4b in step 5 is performed using the knitting needles I, K, and M of the FD.

  FIG. 8 shows a procedure of another method for knitting the knitted fabric 1 having the yarn processing portion of FIG. In FIG. 8, the leading end of the crossover thread 4 is not wound around the stitch but wound around the stitch. That is, after performing Step 1 and Step 2 in the same manner as in FIG. 3, in Step 3, the stitch to be tacked in FIG. 3 is transferred from the knitting needle D of the FD to the knitting needle d of the BU. The point of transferring the knitting needles E to H of the FD to the knitting needles e to h of the BU is the same as that in FIG. In Step 4-1, after the knitting needles N, L, and J of the FD are tucked, the knitting yarn is pulled out from the knitting needle D to the left. In the next step 4-2, the stitches are transferred from the knitting needle d of the BU to the knitting needle D of the FD and returned to the original state. In step 5, the knitting yarn is fed rightward and tacked to the knitting needles j, l, n of the BD. The knitting yarn withdrawn to the left in step 4-1 becomes the forward transition section 4 a of the transition thread 4. By returning the stitches locked to the knitting needle D of the FD in step 4-2 from the knitting needles d of the BD, the portion near the tip of the crossover yarn 4 in the forward crossing section 4a is stitched to the knitting needle D. Pushed out of the mouth in position. The crossover yarn 4 rotates around the inner side of the stitch of the stitch locked to the knitting needle D of the FD by supplying the yarn in the right direction in Step 5, so that it is wound around the stitch locked to the knitting needle D and folded back. Is done. The folded portion of the crossover yarn 4 is locked by the winding around the stitch, and the crossover yarn 4 that is folded back becomes the crossover section 4b of the return path.

  In step 6, by transferring the stitches from the knitting needles e to h of the BU to the knitting needles E to H of the FD and returning them, in the section of the knitting needles E to H, the crossover yarn 4 is pushed out of the front mouth bed, and the cylinder Can be put out as a knitted fabric. Since the folded portion at the tip of the crossover yarn 4 is only wound around the stitch, even when folded at the yarn processing portion 2, it can be locked without being knitted with a tack.

  FIG. 9 shows an example in which the transfer yarn 4 is wound around the stitches locked by the knitting needles D of the FD as in FIG. In Step 3, the stitches locked to the knitting needles E to H are transferred to the BU knitting needles e to h, respectively, without transferring the stitches locked to the knitting needles D of the FD. In step 4-1, the knitting yarn is pulled out to the left of the knitting needle D, and then the stitches locked to the knitting needle D are transferred to the knitting needle d of the BU in step 4-2. The knitting yarn is pushed out of the mouth of the back needle bed with the stitch transferred to the knitting needle d of the BU. By supplying the yarn in the right direction in Step 5, the crossover yarn 4 enters the inside of the seam of the stitch locked to the knitting needle d of the BU, and is wound around the stitch at the folded portion and locked. In step 6, when the stitches locked to the knitting needles d to h of the BU are returned to the knitting needles D to H of the BD, the transition yarn 4 is pushed out of the cylindrical knitted fabric by the stitches locked to the knitting needles E to H. Is done. Regarding the stitches locked to the knitting needles D of the FD, when the stitches are locked to the knitting needles d of the BU before transfer, the inner part of the mouth becomes the outside of the tubular knitted fabric, The portion pushed out of the mouth is the inside of the tubular knitted fabric inside the mouth.

  FIG. 10 partially shows a schematic configuration of the knitted fabrics 11, 21, 31 having a yarn processing portion according to another embodiment of the present invention in the vicinity of the yarn processing portion 2. Elements having portions corresponding to those in FIGS. 1 and 2 are denoted by the same reference numerals, and redundant description is omitted.

  A knitted fabric 11 having a yarn processing portion shown in FIG. 10A is formed by passing the vicinity of the leading end where the crossover yarn 4 is folded through the inside of the cylindrical knitted fabric at the positions of the plurality of stitches 12, 13, and 14. The The bridging yarn 4 is passed through the outside of the tubular knitted fabric between the stitches 12, 13, and 14 or at adjacent stitch positions. In the knitted fabric 11, the locking portions 16 are formed in such a manner that the crossover yarns 4 are alternately passed inside and outside the knitted fabric. The forward crossing section 4a including the yarn processing section 2 and the return crossing section 4b are provided outside the tubular knitted fabric in the same manner as the knitted fabric 1 having the yarn processing section of FIG. However, the locking portion 16 in the section including the plurality of stitches 12, 13, 14 is not locked to the knitted fabric at the leading end of the crossover yarn 4 that is turned back. The crossover yarn 4 in the knitted fabric 11 is simply removed after cutting because the vicinity of the tip passes alternately between the outer side and the inner side of the knitted fabric in the section including the stitches 12, 13, and 14 of the knitted fabric. can do. Since the transition yarns 4 are locked by the plurality of stitches 12, 13, and 14, the transition yarns 4 can be securely locked until they are cut.

  In the knitted fabric 21 having the yarn processing portion shown in FIG. 10B, most of the crossover yarn 4 is fastened inside the cylindrical knitted fabric, and only the vicinity of the turning tip is passed through the stitch 22 to the outside of the cylindrical knitted fabric. The locking portion 26 is formed so as to be exposed to the above. The crossover yarns 4 are locked by the locking portions 26 by alternately passing the inside of the tubular knitted fabric at the stitch 22 and the outside of the tubular knitted fabric at the stitch adjacent to the left side of the stitch 22. Done.

  In the knitted fabric 31 having the yarn processing portion shown in FIG. 10 (c), the transition yarn 4 is unlocked at the tack section 5 and pulled out to the outside of the tubular knitted fabric. Omitted. Even if the crossover thread 4 is not locked, manual cutting is possible.

A schematic procedure for knitting 21 is shown. The description of the knitting in FIGS. 11 to 14 is performed under the same conditions as the descriptions in FIGS. Although the number of knitting needles is described so as to be different from each other, this is for convenience of explanation, and in actual knitting of the knitted fabric, a necessary number of knitting needles may be used.

  11 and 12, the knitted fabric 11 having the yarn processing portion shown in FIG. 10 (a) is knitted. In step 1, the course on the front needle bed side of the tubular knitted fabric is knitted in the left direction with the A-color knitting yarn. Next, the rear needle bed side course is knitted in the right direction with the A-color knitting yarn. Cylindrical knitting by such circular knitting is repeated, and in the last course shown as step 2, knitting is not performed with the final knitting needle w of BD. In this way, the A color area 3a in FIG. 10A is knitted except the final stitch. In step 3, the stitches locked to the knitting needles K to P of the FD corresponding to the section in which the transition yarn 4 in FIG. 10A is pulled out are transferred to the BU knitting needles k to p by transfer. Also, stitches locked to the knitting needles E, G, and I adjacent to the knitting needles F, H, and J of the FD corresponding to the stitches 12, 13, and 14 are moved to the knitting needles e, g, and i of the BU by transfer. Keep it. Further, the stitch that is locked to the knitting needle D of the FD to which the tip of the transition yarn 4 is hung is transferred to the knitting needle d of the BU, and the knitting needle D is left as an empty needle.

  In the next step 4, the A-color knitting yarn is tucked onto the knitting needles V and S of the FD and pulled out from the vicinity of the position of the knitting needle R to the position of the knitting needle D. Further, the forward crossing section 4a shown in FIG. 10A is formed on the knitting needle D which is an empty needle. Next, at step 5-1, the knitting yarn threaded around the knitting needle D is folded back and tacked onto the knitting needles s, v of the BD. The knitting yarn that forms the tack section 5 of FIG. 10A with the knitting needles V and S of the FD and the knitting needles s and v of the BD is from the A color on the forward path side in the yarn processing section 2 of FIG. By switching, the color is switched to B color on the return path side. Next, in Step 5-2, the stitches locked to the knitting needles e, g, i, k to p of the BU are returned to the knitting needles E, G, I, and K to P of the FD. The transition yarns 4 in the positions of the knitting needles E, G, and I and the sections of the knitting needles K to P are located on the front needle bed side on the outer side of the tooth opening with respect to the stitches locked by the respective knitting needles E, G, I, and K to P. Get out.

  In step 6 of FIG. 12, a stitch is formed on the last knitting needle w of the BD with a B-colored knitting yarn. However, the yarn feeding direction is the left direction opposite to the right direction in which the knitting needles A to v are fed to the knitting needles a to v in step 2, and the yarn feeder is kicked back in step 7-1 to Twists are formed, and the yarn feeder is extended to the right side of the knitting width. It is preferable to carry out such a process in order to prevent the difference in level when the knitting yarn is switched from the A color to the B color between the knitting needles W and w, as in steps 7 to 8 in FIG. is there.

  In step 7-2, the eyes of the transition yarn 4 hung on the knitting needle D of the FD are removed. Although the leading end of the crossover yarn 4 is released from the hook of the knitting needle D, it is possible to keep the locked state by alternately passing the inside and the outside of the tubular knitted fabric in the section of the knitting needles E to J. In step 7-3, the stitch is returned from the knitting needle d of BU to the knitting needle D of FD. At this time, the folded portion at the tip of the crossover yarn 4 is pushed out of the tooth opening by a stitch locked to the knitting needle D on the front needle bed side. Hereinafter, in Step 8, the course on the front needle bed side of the tubular knitted fabric is knitted in the left direction with the knitting yarn switched to the B color.

The forward crossing section 4a in FIG. 10 (a) is formed. Next, in step 5-1, the knitting yarn that has been threaded on the knitting needle D is folded back to form the return crossing section 4b. The knitting yarn is switched from the A color on the forward path side to the B color on the return path side by switching at the yarn processing section 2 in FIG. Next, in Step 5-2, the stitches locked to the knitting needles e of the BU are returned to the knitting needles E of the FD. The transition yarn 4 at the position of the knitting needle E is pushed out of the tooth opening by a stitch locked to the knitting needle E on the front needle bed side.

  In Step 6 of FIG. 14, a stitch is formed on the last knitting needle r of the BD with a B-colored knitting yarn. However, the direction of yarn feeding is the left direction opposite to the right direction in which the knitting needles a to q are fed to the knitting needles a to q in step 2, and the yarn feeder is kicked back in step 7-1 so that the knitting needle r Form a twisted eye, and feed the yarn feeder to the right of the knitting width. The formation of such a twisted line is the same as steps 6 to 7-1 in FIG.

  Step 7-2 to Step 7-3 are similar to Step 7-2 to Step 7-3 in FIG. 12, after the eye of the transition yarn 4 hung on the knitting needle D of the FD, and then from the knitting needle d of the BU. The stitch is returned to the knitting needle D of the FD, and the folded portion at the tip of the crossover yarn 4 is pushed out of the tooth opening by the stitch on the front needle bed side. Hereinafter, in Step 8, the course on the front needle bed side of the tubular knitted fabric is knitted in the left direction with the knitting yarn switched to the B color. Hereinafter, when the knitting yarn is switched from the B color to the A color or another color, if the same procedure is repeated, a cylindrical knitting having a border pattern 3 region as shown in FIG.
