Abstract

When knitting a tubular knitted fabric having a difference in the number of wales between a front knitted fabric and a back knitted fabric, knitted fabrics are knitted alternately while turning the tubular knitted fabric and jointing the front section having a large number of wales at middle portions. In one example embodiment, turning is performed such that one boundary of boundaries coupling the fabrics is positioned between front and back needle beds. The numbers of wales of the fabrics caught on the needle beds on both sides are equalized and the fabric of the front section having a large number of wales is knitted from one boundary to the joints at a middle portion of the knitting width. Subsequently, the tubular fabric is turned such that the other boundary is positioned between the needle beds, and the fabric is knitted from the boundary of the front section to the joints and then coupled.

Claims

1. A method of knitting a tubular knitted fabric using a flat knitting machine provided with at least a pair of front and back needle beds such that a front knitted fabric belonging to the front needle bed and a back knitted fabric belonging to the back needle bed are continuously formed on both sides in a knitting width and such that the number of wales is different between the front knitted fabric and the back knitted fabric, comprising:

a step on one side of carrying out turning such that the knitted fabrics caught on the needle beds on both sides have an equivalent number of wales, in which between continuous portions between a knitted fabric having a larger number of wales and a knitted fabric having a smaller number of wales, the continuous portion on one side in the knitting width is positioned between the pair of front and back needle beds, the needle bed to which the knitted fabric having a smaller number of wales belongs catches the knitted fabric having a smaller number of wales, the continuous portion on the other side, and an end portion of the knitted fabric having a larger number of wales, and the needle bed to which the knitted fabric having a larger number of wales belongs catches the knitted fabric having a larger number of wales except for the end portion; and

a step on the other side of carrying out turning such that the knitted fabrics caught on the needle beds on both sides have an equivalent number of wales, in which between the continuous portions between the knitted fabric having a larger number of wales and the knitted fabric having a smaller number of wales, the continuous portion on the other side in the knitting width is positioned between the pair of front and back needle beds, the needle bed to which the knitted fabric having a smaller number of wales belongs catches the knitted fabric having a smaller number of wales, the continuous portion on the one side, and an end portion of the knitted fabric having a larger number of wales, and the needle bed to which the knitted fabric having a larger number of wales belongs catches the knitted fabric having a larger number of wales except for the end portion,

wherein the step on the one side and the step on the other side are alternately repeated,

the knitted fabric having a larger number of wales is provided with a joint, within a range in which the joint is caught on the knitted fabric having a larger number of wales in both of the step on the one side and the step on the other side,

in the step on the one side, in the knitted fabric having a larger number of wales, a portion on the one side from the continuous portion on the one side to the joint is knitted,

in the step on the other side, in the knitted fabric having a larger number of wales, a portion on the other side from the continuous portion on the other side to the joint is knitted, and

the portion on the one side and the portion on the other side in the knitted fabric having a larger number of wales are linked to each other at the joint.

2. The method of knitting the tubular knitted fabric of claim 1, wherein in at least one of the front knitted fabric and the back knitted fabric, a dart is formed in a middle portion in the knitting width by decreasing and then increasing the number of wales in accordance with progress of course knitting.

3. The method of knitting the tubular knitted fabric of claim 2, wherein even when the knitted fabric in which the dart is formed is the knitted fabric having a smaller number of wales, the knitted fabric is knitted separately in the step on the one side and the step on the other side, and linking is carried out at the joint,

the joint is formed so as to be positioned on the same straight line in a wale direction, and

in each of the portion on the one side and the portion on the other side in the knitted fabric, a line in which a narrowing line is continued to a widening line of the dart is formed at the same interval from a line constituted by the joint.

4. The method of knitting the tubular knitted fabric of claim 1, wherein in at least one of the front knitted fabric and the back knitted fabric, a swell is formed in a middle portion in the knitting width by increasing and then decreasing the number of wales in accordance with progress of course knitting.

5. The method of knitting the tubular knitted fabric of claim 1, wherein in at least one of the front knitted fabric and the back knitted fabric, the number of wales is increased or decreased in accordance with progress of course knitting.

6. The method of knitting the tubular knitted fabric of claim 1, wherein the joint provided in the knitted fabric having a larger number of wales is knitted so as to be positioned on the same wale such that the joint is spaced away from the continuous portions between the front knitted fabric and the back knitted fabric, within a range of the knitting width in which the joint is caught on the same needle bed in both of the step on the one side and the step on the other side.

7. The method of knitting the tubular knitted fabric of claim 2, wherein the joint provided in the knitted fabric having a larger number of wales is knitted so as to be positioned on the same wale such that the joint is spaced away from the continuous portions between the front knitted fabric and the back knitted fabric, within a range of the knitting width in which the joint is caught on the same needle bed in both of the step on the one side and the step on the other side.

8. The method of knitting the tubular knitted fabric of claim 3, wherein the joint provided in the knitted fabric having a larger number of wales is knitted so as to be positioned on the same wale such that the joint is spaced away from the continuous portions between the front knitted fabric and the back knitted fabric, within a range of the knitting width in which the joint is caught on the same needle bed in both of the step on the one side and the step on the other side.

9. The method of knitting the tubular knitted fabric of claim 4, wherein the joint provided in the knitted fabric having a larger number of wales is knitted so as to be positioned on the same wale such that the joint is spaced away from the continuous portions between the front knitted fabric and the back knitted fabric, within a range of the knitting width in which the joint is caught on the same needle bed in both of the step on the one side and the step on the other side.

10. The method of knitting the tubular knitted fabric of claim 5, wherein the joint provided in the knitted fabric having a larger number of wales is knitted so as to be positioned on the same wale such that the joint is spaced away from the continuous portions between the front knitted fabric and the back knitted fabric, within a range of the knitting width in which the joint is caught on the same needle bed in both of the step on the one side and the step on the other side.
