Definitions

  • the present invention relates to a knitting method of a fabric by a flatbed knitting machine in which, after a plurality of fabrics are joined by the flatbed knitting machine, it is repeated to move stitch for decreasing an integrated knitting width and to form stitch.
  • Figs.4 show, in Fig. 4(a) a basic structure (for example, see Patent Literature 2) of a flatbed knitting machine 1 to be used for knitting to join fabrics in a simplified manner, and in Fig. 4(b) a state immediately before the knitting to join fabrics of a knitted wear 5 is performed in a simplified manner, and in Fig. 4(c) a problem that is occurred at the time when joining.
  • the flatbed knitting machine 1 is provided with needle beds 3, 4 opposed to each other with respect to a needle bed gap 2 and knits a fabric such as the knitted wear 5 with knitting needles that are arranged to be lined up on each needle bed 3, 4.
  • the fabric that has been knitted is taken down by a take down device, which is provided under the needle bed gap 2 and includes a take down roller 6 and the like. In order to continue knitting fabric stably, the fabric needs to be pulled downward with an appropriate force.
  • a take down device which is provided under the needle bed gap 2 and includes a take down roller 6 and the like. In order to continue knitting fabric stably, the fabric needs to be pulled downward with an appropriate force.
  • sleeves 8 are knitted as separated tubular knitted fabrics at both sides of a body 7, and after the sleeves 8 reach to underarm portions 10a, they are joined to a single tubular body, then performing to move stitches in order to decrease the knitting width so as to reduce the diameter of the tubular body. In such case to move stitch, it is repeated to transfer stitch and to knit stitch, so that it is required to keep a state capable of taking down fabric appropriately in order to perform clear and knock-over reliably.
  • the separation knitting part 9a is inclined to the body 7 side, which is inner side of the knitting width, and a take down force is not applied to the outer side of the knitting width, there is a risk that knitting is not stable.
  • the separation knitting part 9a is required to have enough length to be caught by the take down roller 6 like as the separation knitting part 9b shown in Fig. 4(b) . If the separation knitting part 9b has enough length, the outer side of the knitting width thereof can be also made to be caught by the take down roller 6.
  • the separation knitting part 9b is made to be long in order to cause the take down force to be applied to the outer side of the knitting width thereof before performing to move stitch, stable knitting can be performed, however, the long separation knitting parts 9 and 9b use a large amount of knitting yarns, resulting in increase in production cost.
  • a technique, in which the take down roller 6 is made to retract for enabling a set up device to be used again in the flatbed knitting machine when the short separation knitting part 9a is set up on the way to knit the body 7, has been proposed, however, with the technique, the device is complicated to increase device cost.
  • the present invention provides a knitting method of a fabric by a flatbed knitting machine which is provided with at least a pair of needle beds and a take down device, the needle beds are opposed to each other with respect to a needle bed gap, and the take down device is arranged under the needle bed gap and takes down a fabric which droops after knitted, on the way to knit a base fabric which is to be knitted first, starting to knit an additional fabric, which is shorter in a length of a wale direction than the base fabric, by using a different section of the needle beds from a section of the needle beds which is being used to knit the base fabric, before a lower end of the additional fabric reaches the take down device, joining the additional fabric to the base fabric, and decreasing the knitting width of the fabric after the joining by repeating, to move stitch from the additional fabric side to the inner side of the knitting width of the base fabric, so as to overlap stitch; and to form new stitch subsequent to the overlapped stitch, characterized in that providing a separation knitting part on the lower end of the additional fabric so as
  • said shape of said separation knitting part has:
  • said separation knitting part is formed such that the large width portion and the small width portion have band-like shapes.
  • said base fabric corresponds to a body of a knitted wear
  • said additional fabric corresponds to a sleeve having shorter length than the body.
  • said body has a shape integrally continuous to a skirt portion with a flared bottom and at least a lower end of the skirt portion is knitted by using a section of a large range of needle beds containing the section to be used for knitting said short sleeve, and said separation knitting portion is knitted, after the range of the section of the needle beds to be used for knitting the body, is reduced and does not contain the section to be used for knitting the separation knitting portion.
  • a separation knitting part which is provided on the lower end of the additional fabric is made to have such a shape that an outer end portion, which is opposite to the direction to move stitch, is longer. If the lower end of the separation knitting part reaches a take down device, the lower end is not taken down uniformly, but the outer end portion side can be taken down first by the take down device.
  • the knitting width of the separation knitting part at the outer end portion only is narrowed and is made to have a necessary length, so that a usage amount of knitting yarn can be reduced. Even if the usage amount of the knitting yarn is reduced, a take down force can be made to act on the separation knitting part at the outer side of the knitting width reliably when performing to move stitch, so that it is possible to perform stable knitting.
  • the separation knitting part is formed by a large width portion having a knitting width corresponding to a knitting width of a lower end portion of said additional fabric and a small width portion having a knitting width smaller than that of the large width portion.
  • a usage amount of a knitting yarn for the small width portion is made less than that for the large width portion, and the separation knitting part, when performing to move stitch, is inclined to the outer side of the knitting width opposite to the direction to move stitch so as to be caught by a take down device, so that it is possible to perform stable knitting.
  • take down of the small width portion proceeds, the large width portion is caught by the take down device and a uniform take down force can be made to act on the lower end portion of the additional fabric overall.
  • said large width portion and said small width portion are formed to have band-like shapes, so that said separation knitting part can be knitted while making the respective knitting widths of the large width portion and the small width portion uniform and suppressing the usage amount of the knitting yarns to a minimum limit.
  • a knitted wear having half sleeves or the like which are shorter than a body, can be knitted stably while reducing said separation knitting part.
  • said knitted wear having a body with which a skirt portion with a flared bottom is integrated can be knitted by using needle beds effectively.
  • Figs. 1 show a simplified state where a knitting method of a fabric according to the present invention is applied to a knitted wear 10, as the example 1 of the present invention in (a), a simplified structure of a flatbed knitting machine 1 to be used for knitting, and in (c) a view showing an effect obtained by a separation knitting part 13 at the time when knitting to join fabrics.
  • the knitted wear 10 is knitted as a tubular knitted fabric, for which sleeves 12 are knitted as separated tubular knitted fabrics at both sides of a body 11, when the sleeves 12 reach to underarm portions 10a, they are joined to the body 11 so as to form one tubular body, and then performs to move stitch for narrowing a knitting width so as to decrease a diameter of the tubular body.
  • the knitted wear 10 itself is formed by knitting the same manner as the knitted wear 5 in Fig. 4(b) .
  • the sleeves 12 are started to be knitted on the way to knit the body 11 starting first to be knitted by a flatbed knitting machine 1, which is provided with at least a pair of needle beds 3, 4 being opposed to each other with respect to needle bed gap 2, and a take down roller 6 being arranged under the needle bed gap 2 and taking down the knitted wear 10 which has been knitted and droops.
  • the body 11 is knitted as a base fabric and the sleeves 12 shorter than the body 11 in the wale length are knitted as additional fabrics by using sections different from sections of the needle beds 3, 4 on which the body 11 is knitted.
  • the sleeves 12 are joined to the body 11 as the base fabric and then it is performed to move stitch for decreasing the knitting width of the knitted wear 10 as joined fabric.
  • separation knitting parts 13 provided on the lower ends of the sleeves 12 are different from the separation knitting parts 9, 9a, 9b in Fig. 4(b) .
  • the separation knitting parts 13 are provided on the lower ends of the sleeves 12 so as to be eccentrically located at the sides of outer end portions opposite to a direction to move stitch, which is rather than inner end portions adjacent to a section on which the body 11 is knitted, within the end portions of the sections on which the sleeves 12 are knitted, and so as to be longer at the outer end side.
  • the separation knitting parts 13 have large width portions 13b which have knitting widths corresponding to the lower ends of the sleeves 12, and small width portions 13a which are provided on the lower end portions of the large width portions 13b at the sides of outer end portions and have knitting widths smaller than those of the large width portions 13b.
  • the length from the lower end of the sleeve 12 to the underarm portion 10a is smaller than a height H from the take down roller 6 to the needle bed gap 2 as shown in Fig. 1(b) , however the length becomes sufficient by adding the separation knitting parts 13 to the sleeves 12 by the lengths to the lower ends of the small width portions 13a.
  • the lower ends of the separation knitting parts 13 at the side of the outer end portions can be taken down by the take down roller 6. If the lower ends of the small width portions 13a reach the take down roller 6, the separation knitting parts 13 can be caught by the take down roller 6 in a state of being inclined outward reliably because the lower ends are not uniform and the portions at the sides of the outer end portions are longer. On the separation knitting parts 13, it is sufficient that the small width portions 13a are caught by the take down roller 6 before performing to move stitch, so that the lengths of the separation knitting parts 13 in the wale direction are made shorter so as to have the lengths equivalent to the separation knitting parts 9b in Fig. 4(b) , for example.
  • the knitting widths of the small width portions 13a are smaller, so that a usage amount of knitting yarns for the separation knitting parts 13 can be smaller than that for the separation knitting parts 9b. If it proceeds to take down the small width portions 13a, the large width portions 13b are caught by the take down roller 6 and a uniform take down force can be made to act on the lower end portions of the sleeves 12 overall.
  • Figs. 2 show a shape of separation knitting parts 13 provided on the knitted wear 10 and examples of separation knitting part 14, 15, 16, 17 having other shapes.
  • the small width portions 13a and the large width portions 13b are formed to have band-like shapes and the small width portions 13a are provided on the lower ends of the large width portions 13b at the sides of the outer end portions.
  • the length of the large width portions 13b in the wale direction is defined such that the sleeves 12 are set up stably.
  • a sub roller is provided immediately under the needle bed gap 2 to perform auxiliary take down of the fabric.
  • the length of the large width portions 13b is defined such that the sleeves 12 can be set up in a state where the lower ends of the large width portions 13b are caught by the sub roller.
  • the length of the small width portions 13a is set so as to cover the shortfall in the length of the large width portions 13b which is not enough to be caught by the take down roller 6 before performing to move stitch after the sleeves 12 are knitted to the underarm portions 10a and joined to the body 11 as described above.
  • the number of stitches in the course direction of the small width portions 13a is required, for example, four knitted stitches.
  • small width portions 14a that are similar to the small width portions 13a of the separation knitting parts 13 may be provided on the lower ends of the large width portions 14b that are similar to the large width portions 13b at positions which are deviated inward slightly from the outer end portions thereof.
  • the extent of deviation is set up to approximately the knitting width of the small width portions, for example.
  • the large width portions 13b, 14b and the small width portions 13a, 14a of the separation knitting parts 13, 14 are distinguished from each other as band-like regions having different widths.
  • the large width portions 13b 14b and the small width portions 13a,14a are formed to have band-like shapes on the separation knitting parts 13, 14, so that they can be knitted while making the respective knitting widths uniform and suppressing respective usage amounts of knitting yarns to the minimum limits.
  • separation knitting parts 15, 16 can be formed by joining large width portions 15b, 16b that are similar to the large width portions 13b and small width portions 15a, 16a of which knitting widths vary continuously, respectively.
  • an intermediate portion 17c of which knitting width varies continuously is provided between a band-like small width portion 17a and a large width portion 17b that is similar to the large width portion 13b, and the length of the small width portion 17a and the intermediate portion 17c is made to correspond to the small width portion 13a.
  • a take down force can be made to act on the outer side of the knitting width reliably when performing to move stitch while reducing the usage amount of knitting yarns as in the separation knitting part 13, thereby realizing stable knitting.
  • the sleeves 12 are half sleeves that are shorter than the body 11, however, when a skirt or trousers are integrated with the lower portion of the body 11, the present invention can be also applied to long sleeves.
  • the body 11 may not be a tubular knitted fabric that is knitted so as to surround in the course direction, such as a sweater, alternatively the body 11 may be a C-shaped knitted fabric which has a cut portion in the course direction and is made by reciprocating knitting back and forth between both ends of the cut portion, such as a cardigan.
  • the base fabric and the additional fabrics are not limited to tubular knitted fabrics formed into double layers on the front and rear needle beds 3, 4 and may be a knitted fabric formed into a single layer.
  • the sleeves 12 as the additional fabrics are provided at and joined to both sides of the body 11 as the base fabric in the above example, however the present invention may be applied to a case where an additional fabric is provided at and joined to one side of a base fabric to be moved stitch in the same manner.
  • Fig. 3 shows a simplified structure of a knitted wear 20 to which a connection knitting method of a fabric as an example 2 of the present invention is applied.
  • a body 21 is a base fabric of the knitted wear 20, which has a shape integrally continuous to a skirt portion 21a with a flared bottom. At least the lower end side of the skirt portion 21 a is knitted by using a range W as a section of a wide range of the needle beds 3, 4 containing sections to be used for knitting sleeves 22 shorter than the body 21.
  • the separation knitting parts 13 are started to be knitted on the way to knit the body 21 at the inner side of the range W of the section of the needle beds to be used for knitting the skirt portion.
  • the sleeves 22 as the additional fabrics are started to be knitted from cuffs 22a continuous to the separation knitting parts 13 and the body 21 is knitted to underarm portions 21b in parallel, then the sleeves 22 are joined to the body 21. After joining, an integrated body containing shoulders 22b is formed while performing to move stitch for reducing the knitting width.
  • the separation knitting parts 13 are formed such that the lower ends of the small width portions 13a are caught by the take down roller 6 when performing to move stitch.
  • the section of the needle beds 3, 4 to be used for knitting the sleeves 22 and the separation knitting parts 13 are contained in the range W, however, when the small width portions 13a are started knitting, the knitting width of the body 21 has been reduced. Accordingly, the sleeves 22 and the separation knitting parts 13 can be knitted by using sections different from the section to be used for knitting the body 21. In case the separation knitting parts 9 as shown in Fig. 4(b) are used, the sleeves 8 and the separation knitting parts 9 are required to be knitted on the sections at the outer sides of the knitting width relative to the range W in Fig. 3 . When a ratio of the range W to the length of the needle beds 3, 4 is large and sections to be used for knitting the separation knitting parts 9 cannot be provided at both sides of the range W, the separation knitting parts 9 cannot be knitted.
  • the separation knitting parts 13 and the sleeves 22 are knitted. With this, the knitted wear 20 containing the skirt portion 21a with the flared bottom can be knitted by using the needle beds 3, 4 effectively.
  • the separation knitting parts 13 is knitted by using knitting yarns 24 prepared to be knitted into a separation knitting part 23 provided on the lower end of the skirt portion 21a in a state where the knitting yarns 24 are continuous to the separation knitting part 23.
  • the separation knitting part 23 is taken down by the take down roller 6, the knitting yarns 24 are taken down and the small width portions 13a of the separation knitting parts 13 continuous to the knitting yarns 24 are guided so as to be also caught by the take down roller 6 reliably.
  • the separation knitting parts 13, the separation knitting parts 14, 15, 16, 17 having other shapes as shown in Figs. 2 can be also applied to the knitted wear 20 in the same manner. That is to say, the knitted wear 20 having the body 21 with which the skirt portion 21a with the flared bottom is integrated can be knitted stably while reducing the usage amount of knitting yarns for the separation knitting parts 13, 14, 15, 16, 17 in comparison with separation knitting parts having enough lengths, even when the sleeves 22 are knitted later at the inner side of the section of the needle beds 3, 4 to be used for knitting the skirt portion 21.
  • the configuration in which the separation knitting parts provided on the additional fabrics are knitted with knitting yarns prepared to be knitted into the separation knitting part provided on the lower end of the base fabric, and the lower end of the base fabric and the lower ends of the additional fabrics are made to be connected with the knitting yarns can be also applied to the example 1.
