ABSTRACT:
TECHNICAL FIELD
The present invention relates to a method of knitting fabric with a flat knitting machine and, more particularly, to a method of knitting fabric in which at least a part of loops in a flechage knitting region where yarn is caused to reverse in yarn feed direction at some midpoints of knitting width for knitting the region are transferred between front and back needle beds, for stitch move.
BACKGROUND ART
A variety of knitting methods have been proposed for knitting a fabric which is called integral garment, according to which when a front body of a vest or a sweater is knitted with a flat knitting machine, a neckline opening can be formed on the flat knitting machine to relieve a sewing operation after completion of the knitting. The applicant of this application previously disclosed in Japanese Patent No. 2538421 an integral garment knitting method in which the number of wales around an edge portion of a neckline opening of a vest or sweater is increased to increase a peripheral length of the neckline opening. The way of increasing the peripheral length of the neckline opening of the vest
101
as disclosed in Japanese Patent No. 2538421 will be described with reference to
FIGS. 7 and 8
. According to the knitting method disclosed in Japanese Patent No. 2538421, a front body
101
of the vest is knitted starting at a hem
102
toward a neckline opening
103
and then is forked into a right front body
101
a
and a left front body
101
b
. Starting with the neckline opening
103
, the right front body
101
a
and the left front body
101
b
are each knitted in the flechage knitting. From a line V in
FIG. 7
, the right front body
101
a
and the left front body
101
b
are each moved outwards, to form empty needles between the neckline opening
103
and the right and left front bodies
101
a
,
101
b
and then new loops are formed on the empty needles thus formed, to increase the number of wales around an edge portion
104
of the neckline opening
103
, so as to increase a peripheral length of the neckline opening
103
. Then, a collar
105
is formed around the edge portion
104
of the neckline opening
103
thus increased in number of wale, so that the collar
105
having a large diameter is formed. The knitting mentioned above can make a vest of a high commercial value having the neckline opening that can allow one's head to smoothly pass through when wearing.
The knitting for increasing the peripheral length of the neckline opening of the front body
101
of the vest is described with reference to the knitting course diagram of FIG.
8
. In the following, only the knitting for the left front body
101
b
will be described, because the same knitting is symmetrically performed for the right and left front bodies
101
a
,
1101
b
. The course
1
of
FIG. 8
shows a right side of the vest
101
knitted up to the line V of FIG.
7
. The needles A-D of the front needle bed are used for the neckline opening
103
and the needles E-K of the front needle bed are used for the left front body
101
b
. In the course
2
, the loops of the left front body
101
b
retained on the needles E-K of the front needle bed are transferred to the back needle bed. In the course
3
, after the back needle bed is racked rightward one pitch, the loops of the left front body
101
b
are transferred to the front needle bed, to make the needle E of the front needle bed an empty needle. In the next course
4
, a yarn is fed to the needle E of the front needle bed to form a new loop thereat and also fed to the needles F-L of the front needle bed. In the course
5
, the yarn is fed to the needles L-F of the front needle bed to knit the left front body
101
b
. In the course
6
, the loops on the needles F-L of the front needle bed are transferred to the back needle bed. In the course
7
, after the back needle bed is further racked rightward one pitch, the left front body
101
b
is transferred back to the front needle bed. In the course
8
, a new loop is formed on the needle F of the front needle bed and the yarn is fed to the needles G-M of the front needle bed. In the course
9
, the yarn is fed to the needles M-G of the front needle bed to knit the left front body
101
b
. Subsequently, by repeating the same knitting as the knitting of the courses
6
-
9
, new wale around the edge portion
104
of the neckline opening
103
is added on the needles E-G of the front needle bed to produce the state of the course
10
. Thereafter, in the course
11
, the yarn is fed to the needles N-A of the front needle bed. After this manner, the knitting of increasing the number of wales around the edge portion
104
of the neckline opening is completed. Subsequently, the same knitting is performed for the right front body
101
a
. Thereafter, the collar
105
is formed, with which the front body
101
is completed.
In addition to the knitting mentioned above, the flechage knitting is repeatedly performed to gradually narrow the knitting widths of the right and left front bodies, whereby shoulder drops
9
a
,
9
b
like those formed in the vest of
FIG. 1
are formed. However, according to the method disclosed by Japanese Patent No. 2538421, whenever the right and left front bodies
101
a
,
101
b
are moved outwards, as shown in the courses
3
and
7
of
FIG. 8
, all loops of the right and left front bodies
101
a
,
101
b
are transferred back to the front needle bed before the new loops are formed. Due to this, whenever the number of wales around the edge portion
104
of the neckline opening
103
is increased, the right and left front bodies
101
a
,
101
b
must be transferred between the front and back needle beds repeatedly. Accordingly, when the right and left front bodies
101
a
,
101
b
are knitted in the flechage knitting to form the shoulder drops
9
a
,
9
b
, the loops which are in the rest state must be transferred between the front and back needle beds repeatedly, due to which the increase of the number of wales around the edge portion
104
of the neckline opening
103
may cause problems of yarn breakage, elongation of loop, and the like. Thus, since the method disclosed by Japanese Patent No. 2538421 involves the problem that yarn breakage and like problems may be caused by the repeated loop transfer when the shoulder drops are formed, it has the disadvantage that the number of wales around the edge portion of the neckline opening cannot be increased to a satisfactory extent.
DISCLOSURE OF THE INVENTION
In order to solve the problems mentioned above, the present invention provides a method of knitting a fabric by using a flat knitting machine comprising at least a pair of front and back needle beds, at least either of which can be racked laterally, wherein a flechage knitting region is formed by a flechage knitting wherein a yarn feeder is caused to reverse in yarn feed direction at some midpoints of knitting width to put needle in a rest state sequentially from the needle positioned at an end of knitting width and a stitch move is performed in such a manner that at least a part of loops in the flechage knitting region are transferred between the front and back needle beds to move the loops laterally, and wherein after loops in a stitch move region which are moved laterally whenever an adequate number of courses of the flechage knitting region are knitted are transferred to an opposite needle bed, the front and back needle beds are moved relative to each other and, then, loops of wale which are put in the rest state in a process of the flechage knitting are held on the needle bed opposite to the needle bed on which loops of a next course are formed in a sequent flechage knitting until the stitch move is completed, and only the loops of the wale in which the loops of the next course are formed in the sequent knitting are transferred back to their originally retained needle bed prior to the forming of the loops of the next course, the knitting being repeatedly performed.
According to the construction of the present invention mentioned above, when a knitted fabric is knitte
