The position of the needle bar, etc. may be moved by moving the needle bar cam 6, needle bar crank 7, and needle bar presser base 27 in the lateral direction.

本実施例の説明は、針棒に取付ける針数を三本に限って
行った。In the description of this embodiment, the number of needles attached to the needle bar was limited to three.

然し乍ら三本以上所望の数まで取付けることができるこ
とは前述の通りである。However, as mentioned above, it is possible to attach up to a desired number of three or more.

例えば一本の針棒に取付けた針数が第４図Ａの如＜１２
本等間隔である場合において、針ａから１まで針間隔を
更に狭くしたり広くしたりして等間隔に又は異なる間隔
に設定したいときは、所望の間隔に所望数の針を取付け
た一本の別の針棒を交換してキルテイングマシンに装着
すればよい。For example, the number of stitches attached to one needle bar is <12 as shown in Figure 4A.
If you want to make the needle spacing from needles a to 1 even narrower or wider to set them at equal or different intervals, use one needle with the desired number of needles attached at the desired spacing. Simply replace the needle bar with another one and attach it to the quilting machine.

この様にして一度に針数針間隔を変えることもできる。In this way, you can also change the stitch spacing by several stitches at a time.

本発明のよう＆怪、針棒装置を複数筒の組に分けて、そ

針間隔の設定を行うことを可能にするのは、ルーパー３
３の取付装置に特別の考慮を払ったからである。In the present invention, the needle bar device is divided into a plurality of cylinders, each of which is detachable and movable, and the number of needles can be increased or decreased, and different needle spacings can be set. looper 3
This is because special consideration was given to the mounting device in No. 3.

すなわち従来のキルテイングマシンの複数のルーパーは

らない。In other words, the multiple loopers of a conventional quilting machine are each attached to multiple predetermined looper drive shafts so that they operate transversely to the needles, so once the machine is assembled, the position of the looper cannot be changed. In order to move the needles corresponding to the changed needle positions and participate in the stitch formation, the mounting positions of the respective drive shafts must be moved.

このルーパー駆動軸の取付位置移動は機構的に極めて煩
雑であり且困難である。This movement of the mounting position of the looper drive shaft is mechanically extremely complicated and difficult.

Since it is provided so that it can be moved laterally, it is extremely easy to adjust it according to the needle position.

又糸引風３６についても同様なことがいえる。The same thing can be said about the thread pulling wind 36.

Because it is easy to increase or decrease the number of stitches and adjust the needle spacing, it is easy to increase or decrease the number of stitches and adjust the needle spacing for the entire machine in one quilting machine. , it is extremely useful to be able to construct stitches suitable for many types of sewing purposes using one machine.
