TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in a bind-off process applied to a terminal end portion of a knitted fabric knitted by a flat knitting machine.
[0002]
[Prior art]
2. Description of the Related Art A bind-off processing method is known as a process for preventing the end of a knitted fabric of a knit product such as a sweater from loosening. As a method of performing this bind-off processing by a flat knitting machine, for example, as disclosed in Japanese Patent Application Laid-Open No. 2-91254 of the present applicant, the stitch course at the end of knitting of the knitted fabric is directed from one end of the knitted fabric to the other end. While forming the stitch, the formed stitch is superimposed on the adjacent stitch and is sequentially released from the knitting needle. When the knitted fabric is released from the knitting needles by being sequentially bound off from one end to the other end of the knitted fabric, downward tension is applied to the knitted fabric due to the weight of the knitted fabric or the action of the knitting fabric lowering device. As the number of stitches locked to the knitting needle decreases, the tension applied to the stitch locked to the needle gradually increases, so that the stitch formation is performed under the same loop length (or stitch value). The stitches formed by the effect are stretched. As a result, the sizes of the stitches constituting the chain stitch at the bind-off portion become non-uniform, so that the knitted fabric obtained by such a method causes a decrease in the commercial value of the product.
[0003]
Therefore, in order to address the above-mentioned problem, the present applicant has previously proposed a method disclosed in Japanese Patent Application Laid-Open No. Hei 7-133561. In this method, prior to the bind-off processing, the knitting yarn for suspension is passed over the knitting needle of the needle bed that locks the stitch for which bind-off processing is performed and the empty needle of the needle bed on the opposite side. The stitches are successively bound off from one end of the knitted fabric to the other end while the lower knitting yarn is stretched. According to this method, the stitched stitch is released from the needle, but since the hanging knitting yarn locked to the knitting needle of the other needle bed holds the stitch released from the knitting needle, the stitch is held down. It is possible to prevent the downward tension on the knitted fabric from gradually increasing with the progress of the stitching process, thereby making it possible to uniform stitches to be stitched off.
[0004]
However, in this method, it is a necessary condition that there are a large number of empty needles for hanging the knitting yarn for suspension in a predetermined section on the needle bed in the section where the bind-off processing is performed. If the stitches are locked to all the knitting needles and no empty needles can be secured, the above-described method cannot be performed, and the knitted fabric is restricted by knitting conditions. In addition, in this method, it is necessary to remove the hanging knitting yarn from the knitted fabric after knitting, or preparation is required when using a drawn yarn or a water-soluble yarn as the hanging knitting yarn. .
[0005]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to provide a bind-off processing method that makes uniform the size of a bind-off stitch without being restricted by knitting conditions of a knitted fabric.
[0006]
[Means for Solving the Problems]
In the present invention, at least a stitch of the terminal end portion locked by a knitting needle of a predetermined section on the needle bed of a knitted fabric knitted using a flat knitting machine in which a pair of front and rear needle beds are arranged opposite to each other is used. In a method in which one end is set as a starting point and the bind-off processing is sequentially performed toward the other end, a section where the bind-off processing of the knitted fabric is divided into several sections, and the knitted fabric on the starting side is held for each section. After performing the bind-off processing sequentially on each stitch in the section while keeping the starting side on the needle bed, the bind-off processing of the knitted fabric locked on the needle bed is performed. The starting point is released from the needle bed. Locking of the knitted fabric on the needle bed is performed by supplying and hooking a knitting yarn to one or a small number of empty needles located on the starting side of each section to be bound off, and the locked The knitted fabric is released from the needle bed by removing the hooked knitting yarn from the needle. Alternatively, instead of locking the knitted fabric on the needle bed by the hook, the stitch located on the starting side of the section to be bind-off-processed is divided and wrapped over an empty needle on the needle bed, and the locked state is achieved. The release of the knitted fabric from the needle bed is performed by removing the divided stitches from the needle. While the bind-off processing is sequentially performed on the stitches in the section, the knitted fabric on the starting side is held on the needle bed. Since the knitted fabric is hung on the needle bed by the needle that has locked the stitches that have not been stitched yet, the stitches that are not affected by the weight of the knitted fabric due to the progress of the stitching are not affected. Become. Then, after the binding is completed, the knitted fabric on the starting side is released from the needle bed to finish the knitting.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
A preferred embodiment of the bind-off processing method of the present invention will be described below with reference to the drawings. FIG. 1 shows a knitting block diagram. FIG. 2 is a diagram showing the relationship between the needles on the needle bed and the knitted fabric undergoing the bind-off processing. In the present embodiment, a case will be described in which, after knitting of the final course of the knitted fabric as an example of the knitted fabric 1 having a flat knitting structure, the stitches of the final course are bound off from the left side of the paper to the right. The numbers on the left in the figure indicate the numbers of the knitting blocks, and the arrows next to the numbers indicate the moving direction of the yarn supplying member. The lower alphabet indicates each needle of the needle bed. Further, the number of needles used for knitting is made smaller than the actual number of needles for convenience of explanation.
[0008]
First, the knitting yarn is supplied to the needles b, c, d,..., S, t of the front needle bed by the yarn supplying member 8 in the block 1 and knitting of the knitted fabric course 3 is performed. The needles t, s,..., D, c, and b are supplied and the knitting of the stitch course of the final course 4 of the knitted fabric is performed. Next, from block 3 to block 8, each stitch of the final course of the knitted fabric 1 locked by the needles b, c,... Shows where the eye processing is organized. When performing the bind-off processing of the stitch 4b locked to the needle b in the block 3, the knitting yarn is hooked to the empty needle a on the front needle bed on the needle bed, and then the knitting yarn is supplied to the needle b. The stitch 5b is formed. The place where the knitting yarn is hooked is indicated by reference numeral 6. Subsequently, the stitch 5b formed on the needle b is moved to the opposite needle on the rear needle bed, and the yarn feeding member is moved to the left over the needle b. Then, the stitch 5b moved to the rear needle bed is moved again to the needle c of the front needle bed and overlaps the stitch 4c locked by the needle c. Thus, the binding off processing of the stitch 4b locked to the needle b is completed. Next, a knitting yarn is supplied to the needle c to form a stitch 5c in order to perform a bind-off process of the stitches 4c and 5b locked to the needle c in the block 4, and the stitch 5c formed on the needle c is removed. Transfer to opposite needle on needle bed. Then, after moving the yarn supplying member to the left beyond the needle c, the stitch 5c moved to the rear needle bed is transferred to the needle d of the front needle bed. After the block 5, the knitting of the block 4 is sequentially performed on the stitches 4d, 4e,... Locked by the remaining needles d to s, so that the stitch 4 of the final course of the knitted fabric 1 is subjected to the bind-off processing ( Blocks 5-8). The knitting yarn 6 hooked on the empty needle a keeps being held by the needle a even while the bind-off processing is performed on each stitch. For this reason, as shown in the figure, the needle a holds the starting side of the knitted fabric to be bind-off processed, and even if the stitch 4 of the final course is sequentially released from the needle as the bind-off processing proceeds, the needle a The knitted fabric 1 is hung on the needle bed by the needle that locks the stitch a and the stitch not yet subjected to the bind-off processing. Since the knitted fabric 1 is hung on both sides in the knitting width direction, it is possible to suppress the influence of the knitted fabric 1 on its own weight and the like due to the progress of the binding. In the case where the flat knitting machine is provided with a pulling-down device having a pair of front and rear rotating rolls that can be opened and closed, the flat knitting machine is configured to close the rolls, sandwich the knitted fabric with the rolls, and stop the rotation of the rolls. Is more preferably controlled.
[0009]
Further, as another operation, the starting point side of the bind-off processing is positioned at the fixed point (needle a) on the needle bed, so that the stitch (chain stitch 5 formed at the time of bind-off processing) is based on this fixed point. The formation takes place. The dimensions such as the knitting width and the knitting length of the knitted fabric are actually shorter than those defined by the needles on the needle bed, and the knitted fabric shrinks when released from the needles of the knitting machine. However, since the starting side is fixed during the bind-off processing, an appropriate tension is given at the time of forming the stitch, so that the chain stitch 5 at the bind-off portion can have at least a predetermined length. In the case where the bind-off processing is performed using the hanging knitting yarn of the conventional method, the adverse effect due to the weight of the knitted fabric due to the progress of the bind-off processing can be prevented, but at the same time, the hanging knitting yarn is subjected to the bind-off processing. In order to prevent the lowering effect of the knitting machine from exerting on the stitches formed in the stitch, the tension in the pull-down direction is not applied at the time of stitch formation, the stitch degree is clogged, and the length of the chain stitch at the bind-off portion is reduced. There was a problem that the length was shortened, but there is an advantage that the bind-off processing method of the present invention eliminates the problem.
[0010]
In the state where the stitch processing is performed on the stitch 4s locked to the needle s in the block 8, the knitted fabric 1 is locked only by the needle a and the needle t on the needle bed.
Next, after the knitting yarn is supplied twice to the needle t in blocks 9 and 10 to form a stitch, in the subsequent block 11, the needles a and t are moved forward and backward without supplying the knitting yarn and hooked with the needle a. The knitted yarn 6 and the stitch locked by the needle t are released from the needle, and the knitted fabric 1 is removed from the needle bed to complete the knitting of the knitted fabric.
[0011]
<Modification>
Next, a modified example will be described. In the above-described embodiment, the knitting yarn is hooked to the empty needle, but here, the stitch of the final course locked by the needle of the knitted knitted fabric is divided into the needles of the front and rear needle beds, and the divided stitch is This is an example in which a bind-off process is performed on the other of the divided stitches in a state where one of the stitches is locked to a needle. As a method of dividing the stitch, a so-called extra stitch technique called split knit, transfer knit, split knit, or the like is used, for example. In the case of a spatula needle, as disclosed in Japanese Patent Publication No. 62-52063, the needle holding the additional stitch is advanced to the position where the stitch is transferred, and the needle on the other needle bed is moved to the position where the stitch is received. At the same time, the stitch is formed by supplying the knitting yarn only to the needle advanced to the position where the stitch is moved. As a result, the stitch is wrapped around the needles of the front and rear needle beds to be divided and a subsequent stitch is formed. Further, in the case of a compound needle, the forward or backward movement of the stitch is controlled by controlling the advancing and retreating of the slider at the time of transfer of the stitch without yarn feeding as disclosed in Japanese Patent Application Laid-Open No. 3-279448. There is a method of hanging over the needle.
[0012]
FIG. 3 shows a knitting block in which a stitch is divided by a compound needle disclosed in the above-mentioned JP-A-3-279448. Except for blocks 3, 4 and 11 in FIG. 3, the description is omitted because it is the same as FIG. After the knitting of the final course, in the block 3a, at the start of the bind-off processing, the stitch of the final course locked by the needle b of the front needle bed is also passed over the opposing needle b of the rear needle bed to divide the stitch. Next, in block 3b, a knitting yarn is supplied to the needle b of the front needle bed to form a chain stitch following the stitch of the final course, and the formed stitch is moved to the opposing needle c of the rear needle bed. Thereafter, the needle is moved to the needle c on the front needle bed and overlaps the stitch where the needle c is locked. Block-off processing is performed in blocks 4 to 10 in exactly the same manner as in FIG. Then, after the binding process is completed, the stitches locked by the needle b on the rear needle bed and the needle t on the front needle bed that lock one of the stitches divided in the block 11 are removed from the needles. Although the stitches of the final course are divided into the blocks 3a, a chain stitch formed in the bind-off processing, for example, a stitch formed by the block 3b may be divided and performed instead. After the binding is completed, when one of the divided stitches held by the needle on the needle bed is released from the needle, the same loop structure as in FIG. 1 is obtained. However, there is an advantage in that the knitting yarn is less likely to be slackened in this location than in a method in which the stitch is divided and the leading knitting yarn is hooked in order to hold the leading end side of the bind-off stitch by the divided stitch.
[0013]
FIG. 4 shows another modification. This is applicable when there are a plurality of knitting yarns used for knitting of the knitted fabric, and the knitting yarn is attached to an empty needle on the needle bed to lock the knitted fabric on the needle bed as in the above-described embodiment. Instead of hooking or splitting and knitting a stitch, a knitting yarn constituting a knitted fabric in an empty needle of a needle bed located on the starting side of an unused knitting yarn among a plurality of knitting yarns This is an example in which the knitted fabric is hooked on the needle bed by hooking so as to be entangled with the knitted fabric. After performing the stitch course 14 of the final course of the knitted fabric 10 while moving the yarn supply member 17 to the left, the yarn supply member 18 of the unused knitting yarn is moved to the right to move the needles w, x, and y. Then, the knitting yarns of the yarn supplying members 17 and 18 are entangled with each other by hooking the knitting yarn and then starting the binding knitting by the yarn supplying member 17.
[0014]
In the meantime, the knitted fabric of the knitted fabric may be other than a flat knitted fabric such as a rubber knit, The knitted fabric to be knitted may be a tubular knitted fabric having a two-layer cross section. Further, the binding process is performed while joining the two knitted fabrics while the front and back knitted fabrics are locked to the needles of the front and rear beds, for example, Japanese Patent Application Laid-Open Nos. 2-91254 and 4-209855. Needless to say, the present invention can also be applied to various kinds of stitched knitting, such as Japanese Patent Application Laid-Open No. Hei 7-316958.
Further, in each of the above-described embodiments, the single empty needle a of the front needle bed located outside the knitting width of the knitted fabric is used immediately before the knitting of the bind-off processing is started. Instead, it can be changed as appropriate as long as it holds the starting side of the knitted fabric to be bind-off processed and exhibits the same action as the present invention. Therefore, as the empty needle for holding the starting point side of the bind-off processing, use any of the needles on the front and rear needle beds as well as the inside and outside of the knitting width, or use the needle whose stitch was released during the bind-off processing. You may.
In addition, when there are many stitches to be bind-off processed in the section, the section is divided into several sections, and the knitted fabric on the starting side is retained for each section, so that the yarn having a small tensile strength and easy-to-cut is formed. It is convenient in some cases. In this case, the knitting yarn or stitch held on the needle bed is dropped at a time after the binding process is completed.
Also, holding the starting side of the bind-off processing on the needle bed is performed after the bind-off processing is started several times after the bind-off processing is started as long as the bind-off processing is not affected by the weight of the knitted fabric. Alternatively, it may be performed at the time of knitting the final course of the knitted fabric before the start of the bind-off processing or several courses before. If the processing is performed before the binding processing is started, a knitting yarn different from the knitting yarn used for the binding processing can be used.
[0015]
【The invention's effect】
As described above, in the method of the present invention, at least one of the original empty needles or the empty needles formed at the time of the bind-off processing may be used, so that the rubber knitted fabric or the tubular knitted fabric may be used. As described above, the present invention can be applied to a knitted fabric knitted by using all the needles, and there is no longer a limitation due to knitting conditions as in the related art.
