応する上下送り軸腕9a、9bとによって構成し、上記
送り軸5a、5bの揺動角度を夫々独立に変え得るよう
にする。In the present invention, as shown in FIG. 1, the feed shaft 5 in the conventional feed dog drive device shown in FIG. 5 is replaced with a hollow feed shaft 5a.
and a feed shaft 5b extending through the feed shaft 5a, and the feed bar @6 is configured by the feed shaft 5a and the feed shaft 5b, respectively.
5b, and the feed plate 7 is constituted by feed plate arms 6a, 6b and feed dog 4, respectively.
The upper and lower feed shaft arms 9 are configured by upper and lower feed shaft arms 9a and 9b that correspond to the feed tables 7a and 7b, respectively, and the upper and lower feed shaft arms 9 are configured by upper and lower feed shaft arms 9a and 9b that correspond to the feed tables 7a and 7b, respectively. The swing angles of the 5b can be changed independently.
本発明のミシンの送り歯駆動装置は上記のような構成で
あるから上記送り軸5a、5bの揺動角度に差を付けれ
ば、これによって夫々の送り歯4a、4bによる布の送
り量に差を生じ、布の送り方向を右曲がり又は左曲がり
等のように任意に変化することが出来る。Since the feed dog drive device of the sewing machine of the present invention has the above-described configuration, by making a difference in the swing angle of the feed shafts 5a and 5b, the amount of cloth fed by the respective feed dogs 4a and 4b can be made different. The feeding direction of the cloth can be changed arbitrarily, such as turning to the right or turning to the left.
