周知の布送り作用を行なう。 To describe the operation of the above configuration, the first feed table 6 does not reciprocate in the horizontal direction due to the swing of the horizontal feed shaft 1, and the first feed table 6 moves up and down via the feed arm 15 due to the swing of the vertical feed shaft 13. Because it moves back and forth in the direction,
The combination of both motions forms a periodic motion similar to a quadrilateral. Since the sub-feed table 7 is integrated with the main feed plate 6 via the eccentric pin 16, the sub-feed table 7 similarly makes a periodic motion close to a substantially quadrilateral shape.
Therefore, the main feed dog 18 and the sub feed dog 19 are
Perform the well-known cloth feeding action.

れば、容易に行なうことができる。 The height of the main feed dog 18 is adjusted by tilting the upper and lower feed arms 15 and eccentrically positioning the feed shaft 8. On the other hand, the approximate height of the sub-feed dog 19 can be set by moving its elongated hole 19a along the screw 21 and tightening the screw 21 at an appropriate position, and then rotating the eccentric pin 16. This can be fine-tuned. Further, the inclination of the sub-feed dog 19 in the front-back direction can be easily performed by rotating the eccentric pin 16.

る。 Incidentally, when the dial nut 24 is rotated, the pin 23b of the T-shaped member 23 moves up and down, and the pitch between the center of the pin 23b and the center of the horizontal feed shaft 1 changes.
The horizontal momentum of the sub-feed dog 19 can be changed.
