The feed dog is designed to give four movements: back and forth movement and up and down movement.

装置について提案した。 In response, the present applicant has developed a feeding device as shown earlier, that is, a rotating body 2 that rotates in conjunction with the rotary hook 1 and has an end cam formed on its upper surface, and a bracket 3 on one side that rotates back and forth and pivots in the vertical direction. A feed bar 4 is movably supported, and the other side is supported by the end cam of the rotating body 2, and an eccentric pin 6 is provided protruding from the rotating body and fits into a horizontal hole 5 formed in the feed bar 4. proposed a feeding device.

なくなつて布曲がりを生じる。Problems to be Solved by the Invention In the feeding device shown in the figure, the feeding dog is moved back and forth as well as up and down based on the rotational movement of a single rotating body. Although the structure is extremely simple compared to the structure that used a moving mechanism and a vertical moving mechanism, if there is even a slight play in the support part of the bracket 3, the feed dog 7 will move in the direction perpendicular to the feeding direction. The wobbling (in the direction of the arrow in FIG. 1) increases, and the fabric is no longer fed straight, causing the fabric to bend.

A cylindrical body top 12 which is coaxially provided on the rotating body and protrudes between both partition walls is fitted, and a pin 6 is further provided on the cylindrical body and protrudes at an eccentric position on the cylindrical body, and the feed base 4 It fits into the horizontal hole 5 formed in the. In addition, 1 in the figure
Reference numeral 3 denotes a convex portion formed on the center shaft side of each partition wall 11 to engage with the end cam 14 on the rotating body, and the convex portion is always pressed against the end cam 14 by a spring 15. However, the feed base 4 is the end face cam 1.
As the eccentric pin 6 rotates, it pivots vertically about the pivot 9, and as the eccentric pin 6 rotates, it reciprocates in the front-rear direction. During operation, the cylindrical body 12 rotates while being fitted between the partition walls, but since it is not eccentric, the feed table 4 does not move in a direction perpendicular to the feeding direction.

生じない。Effects As described above, in the present invention, a regulating means is provided on the side of the feed table to prevent it from moving in a direction perpendicular to the feed direction, so that the feed teeth do not run out and the fabric does not bend.
