[Disclosure of the Invention]
[Technical Problem]
[0004] The present invention aims to provide a knitting method for strengthening a lateral
end part in a knitted fabric in a different process from that of Patent Citation 1
cited above, and to provide the knitted fabric.
[Technical Solution]
[0005] The present invention provides a knitting method for strengthening a lateral end
part in a knitted fabric, using a flatbed knitting machine having at least one pair
of front and back needle beds, wherein after a twisted stitch is formed on a back
side of the knitted fabric, a stitch in the lateral end part in the knitted fabric
is formed, then a new stitch following the twisted stitch and the stitch on the front
side facing the twisted stitch is formed by tubular knitting, and then the stitch
on the front side and the stitch on the back side which are formed by the tubular
knitting are overlapped with each other.
[0006] In the present invention, the lateral end part in the knitted fabric is formed at
each side of a bifurcating part from which the knitted fabric is separated into right
and left, and at least a pair of right and left stitches arranged in sandwich relation
to the bifurcating part are crossed with each other to form a cross part in the bifurcating
part.
[0007] Also, the present invention provides a knitted fabric knitted using a flatbed knitting
machine and having a strengthened lateral end part therein, wherein a twisted stitch
is formed on a back side of the knitted fabric before a stitch is formed in the lateral
end part in the knitted fabric, a new stitch following the twisted stitch and the
stitch on the front side facing the twisted stitch is formed by tubular knitting,
and the stitch on the front side and the stitch on the back side which are formed
by the tubular knitting are overlapped with each other.
[Advantageous Effects]
[0008] According to the present invention, the stitch in the lateral end part in the knitted
fabric is formed after the twisted stitch is formed on the back side of the knitted
fabric, then the new stitch following the twisted stitch and the stitch on the front
side positioned to face the twisted stitch is formed by the tubular knitting, and
then the stitch on the front side and the stitch on the back side which are formed
by the tubular knitting are overlapped with each other. This can provide the result
that the lateral end part in the knitted fabric can be increased in thickness and
thus in strength. Also, since the lateral end part in the knitted fabric can be increased
in strength, the line along which the lateral end part extends can be shaped into
a beautiful line. It is to be noted here that the term of the stitch used herein covers
not only a knitted stitch but also a tuck stitch or a double stitch.
[0009] Also, according to the present invention, the lateral end part in the knitted fabric
is formed at each side of the bifurcating part from which the knitted fabric is separated
into right and left, and at least a pair of right and left stitches positioned in
sandwich relation to the bifurcating part are crossed with each other to form a cross
part in the bifurcating part. The tubular knitting can provide the result that the
tension of the knitting yarn can be relieved so that the stitches used for crossing
can be easily transferred without being tensed. This can provide the result that the
area of the knitted fabric at the cross part and closest to the bifurcating part can
also be made free from tension, so that the knitted fabric can be beautifully shaped.
[0010] In the knitted fabric of the present invention, since the lateral end part is increased
in thickness and thus in strength, a V-neck part of a sweater or an armhole of a vest
can be shaped into a beautiful line.

[Mode for Carrying out the Invention]
[0012] In the following, the knitting of a V-neck part of the vest is described as a certain
embodiment of the present invention. In the knitting described in the following, a
two-bed type flatbed knitting machine is used which comprises a pair of front and
back needle beds, the back needle bed of which is capable of being racked relative
to the front needle bed, and at least two yarn feeders arranged over the needle beds.
For convenience of explanation, a fewer number of knitting needles than they are really
used are represented in the knitting diagram.
[Embodiments]
[0013] Fig. 1 is a view showing a front body 1 of a V-neck vest. The front body 1 of the
vest knitted in the embodiment is wholly knitted in plain knitting. The front body
1 comprises a full-width part 4 knitted up to a bifurcating part 2 in a direction
indicated by an arrow W, a right shoulder part 6 and a left shoulder part 7 which
are knitted while being separated into right and left from the bifurcating part 2.
Reference numeral 8 indicates an opening, and reference numeral 9 indicates a lateral
end part. The full-width part 4 and the right shoulder part 6 are knitted by using
a yarn feeder 10, and the left shoulder part 7 is knitted by using a yarn feeder 11.
A chain line X-X indicates a boundary line in the bifurcating part 2.
[0014] Figs. 2 and 3 are knitting diagrams showing the knitting of the bifurcating part
2 of the front body 1 shown in Fig. 1. Fig. 4 is a knitting diagram showing the knitting
process of a cross part in the bifurcating part 2 taken in the first three steps and
the subsequent knitting process of the right shoulder part 6 and the left shoulder
part 7 following the bifurcating part 2. Figs. 5-7 are knitting diagrams showing the
knitting processes following the knitting process of Fig. 4. Numbers at the left side
of the knitting diagrams designate knitting steps (S), and horizontal arrows designate
knitting directions and vertical arrows designate stitch-transfer directions. Reference
symbols FB and BB designate a front needle bed and a back needle bed, respectively.
Alphabetical letters A-T of big letters designate knitting needles of FB, and small
letters a-t designate knitting needles of BB. Circles indicate new stitches formed
or transferred in the respective knitting steps, Vs indicate tuck or pick-up stitches,
and double circles indicate double stitches. Illustration of the stitches which are
not involved in the knitting in the knitting steps and remain retained by the knitting
needles during the knitting is omitted. A line X-X indicates a boundary line of the
bifurcating part 2, as in the case of Fig. 1. The FB side may be represented as the
front side and the BB side may be represented as the back side.
[0015] In the following, the knitting steps S1-S28 shown in Figs. 2-4 are described. S1
shows the knitting of the full-width part 4 of the front body 1. The yarn feeder 10
is moved leftwards via a carriage (not shown) and the stitches are formed by the knitting
needles T-A of FB. In the subsequent steps from S2, the yarn feeder 10 and the yarn
feeder 11 are used for the knitting prior to forming the cross part.
[0016] In the step S2, the yarn feeder 11 is used so that stitches are sequentially formed
by the knitting needles T-N in the leftward direction. In the step S3, a stitch is
picked up to the right by the knitting needle m, and in the next step S4, a stitch
31 is formed by the knitting needle M of FB. Though these steps, the knitting yarn
extending from the knitting needle m to the knitting needle M of FB crosses over the
knitting yarn extending from the knitting needle N of FB to the knitting needle m
of BB, whereby a twisted stitch 21 is formed at the knitting needle m. Thereafter,
the same knitting steps as S3-S4 are taken in the steps S5-S6 and S7-S8, so that stitches
32 and 33 are formed by the knitting needles L and K, respectively, while also twisted
stitches 22, 23 are formed by the knitting needles 1 and m, respectively. In the step
S9, new stitches are formed to the right with respect to the twisted stitches 23,
22, 21 formed on the back side of the front body 1 in the steps S3-S8 and also tucked
by the knitting needle N of FB. In the step 10, stitches are formed to the left by
the knitting needles M-K of FB. In the step 11, stitches are formed to the right by
the knitting needles k-m of BB. In the steps S9-S11 mentioned above, tubular knitting
is carried out to move in a circular direction, using the knitting needles K-M of
FB and the knitting needles k-m of BB, whereby new stitches following the twisted
stitches 23, 22, 21 and the stitches 31, 32, 33 positioned to face them are formed,
so that the corresponding area of the knitted fabric is joined in a tubular form.
Then, in the step S12, the stitches retained by the knitting needles k-m of BB are
respectively transferred to and overlapped with the stitches retained by the knitting
needles K-M of FB. In the step S13, the yarn feeder 11 is moved leftwards for a while
and then stitches are formed by the knitting needles N-T of FB, so as to continue
from the stitch at the knitting needle M.
[0017] S14-S25 are in a symmetrical relation to the knitting of S2-S13 mentioned above with
respect to the line X-X. In the step S14, the yarn feeder 10 is used so that stitches
are sequentially formed to the right by the knitting needles A-G. In the step S15,
a stitch is picked up to the left by the knitting needle h, and in the next step S16,
a stitch is formed by the knitting needle H of FB. As a result of this, a twisted
stitch is formed at the knitting needle h of BB. Thereafter, the same knitting steps
as S15-S16 are taken in the steps S17-S18 and S19-S20, so that stitches are formed
by the knitting needles I and J, respectively, while also twisted stitches are formed
by the knitting needles i and j, respectively. In the step S21, new stitches are formed
to the left with respect to the twisted stitches formed on the back side of the front
body 1 in the steps S15-S20 and also tucked by the knitting needle G of FB. In the
step S22, stitches are formed to the right by the knitting needles H-J of FB. In the
step S23, stitches are formed to the left by the knitting needles j-h. In the steps
S21-S23 mentioned above, tubular knitting is carried out to move in a circular direction,
using the knitting needles H-J of FB and the knitting needles h-j of BB, whereby new
stitches following the twisted stitches and the stitches positioned to face them are
formed, so that the corresponding area of the knitted fabric is joined in a tubular
form. Then, in the step 24, the stitches retained by the knitting needles h-j of BB
are respectively transferred to and overlapped with the stitches retained by the knitting
needles H-J of FB. In the step S25, the yarn feeder 10 is moved rightwards for a while
and then stitches are formed by the knitting needles G-A of FB, so as to continue
from the stitch at the knitting needle H.
[0018] S26-S28 are the steps of crossing the stitches beyond the boundary of the bifurcating
part 2. In this embodiment, the stitch on the front side, arranged in sandwich relation
to the bifurcating part 2, is transferred to and overlapped with the stitch on the
back side formed next to the twisted stitch, so that it is crossed beyond the boundary
of the bifurcating part 2. In the step S26, the stitches at the knitting needles J
and K are respectively transferred to and overlapped with the stitches at the knitting
needles j and k. In the step S27, the double stitch retained by the knitting needle
k is transferred to the knitting needle J beyond the boundary of the bifurcating part
2. In the step S28, the double stitch retained by the knitting needle j is transferred
to the knitting needle K beyond the boundary of the bifurcating part 2. The crossing
of the stitches in the bifurcating part 2 is completed in the manner as mentioned
above.
[0019] Since in the steps S9-S11 and S21-S23, the tubular knitting is provided following
the twisted stitches and the stitches positioned to face them, the area near the cross
part can be strengthened by a thick and substantial knitted fabric.
[0020] Although in the illustrated embodiment, the cross part is formed by the stitch-transfer
process in the steps S26-S28, the cross part may be formed by an alternative overlapping
and crossing process, without being limited to such an illustrated process. For example,
as an alternative process, the stitches on the front side, positioned in sandwich
relation to the boundary of the bifurcating part 2, are crossed with each other first,
and, then, the stitches on the back side may be transferred to across the boundary
of the bifurcating part 2 and overlapped with the stitches on the front side. In this
alternative process, the stitches may be overlapped in a different positional relation
from that in the embodiment. Also, in this alternative process, a known holding technique
may be used (See Japanese Patent No.
2995464, for example). In the case where a four-bed type flatbed knitting machine is used,
an upper needle bed may be used for that process. The stitch-transfer process described
in the embodiment is more advantageous than those alternatives in that the number
of processes can be lessened.
[0021] Next, the knitting of the right shoulder part 6 and left shoulder part 7 following
the bifurcating part 2 is described with reference to Fig. 4 showing the steps subsequent
to S29 and Figs. 5-7. After the stitches are crossed in the bifurcating part 2, as
mentioned above, the narrowing process is carried out so that while the knitted fabric
of the right shoulder part 6 and the knitted fabric of the left shoulder part 7 are
knitted, respectively, the lateral end parts 9R, 9L on their side facing the boundary
of the bifurcating part 2 can gradually increase in distance from the boundary of
the bifurcating part 2. By this knitting process, an opening 8 of the V-neck part
is formed.
[0022] The knitting steps S29-S36 are fundamentally the same as the steps S2-S13 mentioned
above, although they are different in number of twisted stitches formed and in presence
or absence of the stitch-transfer process. In the step S29, the yarn feeder 11 is
used so that stitches are sequentially formed to the left by the knitting needles
T-N. In the step S30, a stitch is picked up to the right by the knitting needle m,
and in the next step S31, a stitch 51 is formed by the knitting needle M of FB. As
a result of this, a twisted stitch 41 is formed at the knitting needle m of BB. Likewise,
in the step S32, a stitch is picked up to the right by the knitting needle 1, and
in the next step S33, stitches 52, 53 are formed by the knitting needles L and K.
As a result of this, a twisted stitch 42 is formed at the knitting needle 1. In the
step S34, new stitches are formed to the right with respect to the twisted stitches
42, 41 formed on the back side of the front body 1 in the steps S30-S33 and also tucked
by the knitting needle N of FB. In the step S35, stitches are formed to the left by
the knitting needles M-K of FB. In the step S36, the tubular knitting is done, forming
stitches by the knitting needles 1 and m of BB, and then stitches are formed by the
knitting needles N-T. In the step S37, the stitches at the knitting needles K-R are
transferred to the knitting needles k-r, so that double stitches are formed at the
knitting needles 1 and m. In the step S38, the stitches at the knitting needles k-r
are transferred to the knitting needles L-S, for the narrowing. As a result of this,
the lateral end part 9L in the left shoulder part 7 increases in distance from the
boundary of the bifurcating part 2. Although in the process mentioned above, a twisted
stitch is not formed at the knitting needle k in the steps S33-S34, the twisted stitch
may be formed in the same manner as in the steps S30-S31. As an alternative to the
stitches 51, 52, 53 which are knitted stitches formed by the knitting needle M in
the step S31 and by the knitting needles L, K in the step S33, tuck stitches may be
formed. The tucking can tighten up the lateral end part 9L to produce a further strengthened
lateral end part.
[0023] The knitting of S39-S48 is in a symmetrical relation to the knitting of S29-S38 mentioned
above with respect to the line X-X. In this regard, however, the yarn feeder 10 is
used. By the narrowing in the step S48, the lateral end part 9R in the right shoulder
part 6 is gradually increased in distance from the boundary of the bifurcating part
2.
[0024] The steps S49-S57 are substantially the same as the steps S29-S38 mentioned above.
In this regard, however, since the narrowing is done in the step S38, the knitting
needles are each shifted rightwards from usual position by one. In the step 57, the
stitches at the knitting needles m and n are transferred to and overlapped with the
stitches at the knitting needles M and N, without using the narrowing in the step
S38.
[0025] The knitting of S58-S66 is in a symmetrical relation to the knitting of S49-S57 mentioned
above with respect to the line X-X. In this regard, however, the yarn feeder 10 is
used.
[0026] In the knitting processes subsequent to S66, the processes including the narrowing
in the steps S29-S48 and the processes not including the narrowing in the steps S49-S66
may be alternated every predetermined course by being repeated for example in an alternate
order, to form the opening 8 in the V-neck part.
[0027] In the knitting processes subsequent to S29 of Fig. 4, the knitting yarn connecting
between the stitches on the front side and on the back side of the knitted fabric
on the side closest to the boundary in the bifurcating part 2 is produced by the tubular
knitting and also the stitch on the front side formed by the tubular knitting and
the stitch on the back side are overlapped with each other, whereby the area around
the opening of the V-neck is increased in thickness and thus in strength. As a result
of this, since the area around the opening can be prevented from undulating or curling,
the V-shaped opening can be beautifully contoured. Also, the forming of the twisted
stitch and the tubular knitting following it are provided, as in the case of the knitting
of the stitches to form the cross part shown in S1-S28. Therefore, substantially the
same visual attractiveness and substantially the same thickness of the knitted fabric
can be provided to the area around the opening of the V-neck including the bifurcating
part.
[0028] Although in the illustrated embodiment, the tubular knitting after the forming of
the twisted stitches rounds in a single direction, as shown in e.g. the steps S2-S13,
the tubular knitting is not limited to this process. For example, as an alternative,
after a final tuck in the step S9, the knitting may be reversed in direction to turn
around at that final tuck so that the stitches may be formed in the order of the knitting
needles m, 1, k on the back side and the knitting needles K, L, M on the front side.
[0029] Although in the illustrated embodiment, the knitting needles, two or three at each
side, are used for forming the twisted stitch, the number of knitting needles used
may be varied to e.g. one at each side or three or more at each side. Also, the number
of knitting needles used for the tubular knitting following the forming of the twisted
stitch may be varied properly according to such variation.
[0030] Although in the illustrated embodiment, the knitting of the front body 1 using the
two-bed type flatbed knitting machine has been disclosed, the present invention is
applicable to known tubular knitting that a tubular body whose front body and back
body are joined at both lateral sides thereof is knitted on the flatbed knitting machine.
Although in the illustrated embodiment, the knitting of the bifurcating part in the
V-neck front body is illustrated as one example, the present invention is not limited
to the illustrated embodiment but is applicable to e.g. the knitting of a vest having
a placket formed to extend straight, without using the narrowing technique as shown
in e.g. the steps S38 and S48.
