ABSTRACT:
TECHNICAL FIELD
The present invention relates to a knitted fabric joining method for forming machi (godets) at joints of tubular fabrics and to a joined knitted fabric.
BACKGROUND ART
Knit goods have parts, called machi (godets), formed at joints thereof. The machi are formed at underarms and crotches of the knit goods, to add more profound or depth to knit goods of a two-dimensional knitted fabric and produce the knit good suitable to one's figure and comfortable to wear.
In the following, a known method for forming machi

in a sweater

in knitting on a knitting machine will be described with reference to FIG.

. The sweater
101
comprises right and left sleeves

105
comprising front sleeves

and a body
106
comprising a front body
106

and a back body
106
b
. In the step A, the body
106
is knitted from a rib
109
, and the sleeves
104
,
105
are knitted from cuffs
111
,
113
in the direction indicated by an arrow Q. In the step B, the right and left sleeves
104
,
105
and the body
106
are each independently knitted in a tubular form until the sleeves
104
,
105
and the body
106
are joined together at the underarms of the sweater
101
. The right and left sleeves
104
,
105
and the body
106
are knitted up to the underarms at which they are abutted with each other, while their knitting widths are gradually increased. In the step C of the joining process for forming the machi (godets)

104
,
105
, each of the sleeves
104
,
105
is shifted toward the body. Then, loops of the sleeves
104
,
105
at their side ends on the body side are laid over loops of the body
106
, and then loops of the next course are formed at those double loops. Then, the newly formed loops are further laid over the loops at the interior side thereof and the next loops at the side ends of the sleeves
104
,
105
. This knitting is repeated to form the machi
103
a
,
103
b
and the line ZY of the sleeve
104
and the line z-y of the body
106
are joined together. In the step D, after the completion of forming the machi

a
,
103
b
, the yarn is fed circularly to the right and left sleeves
104
,
105
and the body
106
, and whenever an appropriate number of courses are knitted in the sleeve
104
,
105
, each of the sleeves
104
,
105
is shifted toward the body to join together the line Y-X of the sleeve and the line y-x of the body
106
. In the next step E, the yarn feed to the sleeves
104
,
105
is stopped at the joints at which the upper end line X-W of the sleeves
104
,
105
and the line x-w of the body are joined together, and whenever an appropriate number of courses are knitted in the body
106
, each of the sleeves
104
,
105
is shifted toward the body to join together the sleeves
104
,
105
and the body
106
. In the sweater
101
knitted in this manner, the sleeves
104
,
105
are joined to the body
106
in the step C, while the loops in the next course are formed in the sleeves
104
,
105
. Thus, regions R are formed in the sleeves
104
,
105
, and the lines Z-Y of the sleeves
104
,
105
, and the lines z-y of the body are joined together. As a result of the sleeves and the body being joined together in this manner, when the sleeves
104
,
105
are rotated from the body
106
centered on the machi

and spread out therefrom, the sleeves
104
,
105
cannot rotate further from their right-angled intersection with the body, as shown in
FIG. 16
showing the top positions of the sleeves
104
,
105
of the sweater
101
. This causes a restraint on free motion of the human body when wearing and provides uncomfortableness to wear. For convenience of explanation,
FIG. 16
shows the uppermost positions of sleeves
104

105
when rotated from the body
106

It is an object of the present invention to disclose a knitted fabric joining method wherein one tubular fabric to be joined to form the machi can be allowed to rotate up to a larger angle than its right-angled intersection with the other tubular fabric in the direction in which the distance between the both knitted fabrics increases, and a knitted fabric comprising tubular fabrics which are joined together in such a manner that one tubular fabric can rotate up to a larger angle than its right-angled intersection with the other tubular fabric in the direction in which the distance between the both knitted fabrics increases. It is another object of the present invention to disclose knitwear of a high degree of freedom of motion of the human body
DISCLOSURE OF THE INVENTION
To accomplish the objects mentioned above, the present invention provides a knitted fabric joining method for knitting at least two tubular fabrics, each comprising front and back knitted fabric parts opposite to each other in front and back, and joining together the at least two tubular fabrics in an overlapping relation by using a flat knitting machine comprising at least a pair of first and second needle beds, which are extended laterally and confront each other in front and back; each of which has a large number of needles; and at least either of which can be racked laterally to transfer loops between the front and back needle beds, the method comprising a knitted fabric joining step that loops of a final course in a joining region of a tubular fabric to be joined, which comprise a proper number of wale and are located at a side end portion thereof, and loops of a final course in a joining region of another tubular fabric are laid over each other in such a relation that the loops located at near side from a boundary between the front knitted fabric part and the back knitted fabric part are combined with each other and the loops located at far side therefrom are combined with each other, so as to be bound off, whereby a machi is formed at a joining point of the two tubular fabrics, and an integrated tubular fabric is knitted continuously from that joined tubular fabric.
The knitted fabric joining method of the present invention may comprise the steps:
a) that in the process of knitting first and second knitted fabrics in a half-gauge knitting and joining together those knitted fabrics, one of first and second needle beds is racked in a first direction with respect to the other needle bed and then a loop of the first knitted fabric at a side end thereof on the second knitted fabric side, which loop is retained on the first needle bed, is transferred to outside of a loop of the first knitted fabric at a side end thereof retained on the second needle bed and a loop of the first knitted fabric at a side end thereof opposite to the side end on the second knitted fabric side, which loop is retained on the second needle bed, is transferred to outside of a loop of the first knitted fabric at the side end thereof retained on the first needle bed, this knitting being repeated, whereby the first knitted fabric is made to circle in the first direction so that the loops in the joining region of the first knitted fabric can all be retained on the second needle bed,
b) that the one needle bed is racked in the first direction and then a loop of the second knitted fabric at a side end thereof on the first knitted fabric side, which loop is retained on the second needle bed, is transferred to outside of a loop of the second knitted fabric at a side end thereof retained on the first needle bed and a loop of the second knitted fabric at a side end thereof opposite to the side end on the first knitted fabric side, which loop is retained on the first needle bed, is transferred to outside of the loop of the second knitted fabric at a side end thereof retained on the second needle bed, this knitting being repeated, whereby the second knitted fabric is m
