セット位置を調整することにより行われる。That is, the bifurcated vertical feed arm 24 moves back and forth due to the reciprocating movement of the vertical feed rod 15 disposed on one vertical feed cam 13 on the lower shaft. This back and forth movement is caused by the vertical feed arm 24.
Horizontal feed arms 28 and 36 are coupled together and are operated by feed rod 9, and vertical feed rods 31 and 31 provide horizontal and vertical movement to the feed table 19 and the two rivers. That is, this movement is transmitted to the joints with the left and right feed tables 19 and 20, and the feed 21 has horizontal and vertical differences due to the left and right feed tables 19 and 201 via the fulcrum shaft 22 and square pieces 23, 23, respectively. Dynamic feed is transmitted. The direction of the feed movement is adjusted by disengaging the feed cam pawl 6 and the feed cam 4 by pressing the pin 16, and adjusting the set position of the feed cam 4.

両面にわたる合理化に寄与し得るものである。In the present invention, the operation of one vertical feed cam provided on the geta and the vertical feed rod on the cam is transmitted to one forked vertical feed arm, and the two left and right feeds are transmitted via a link mechanism. Since the table is given horizontal and vertical feed motion, there is no need for special feed amount difference absorbing means added to either side of the left or right feed table, which was conventionally seen. Therefore, it is possible to eliminate the above-mentioned conventional defects, and contribute to streamlining both manufacturing and sewing operations.
