At this time, since the grooves of the horizontal moving body conductor 12 are moved, the upper feeding tooth support portion 18 is connected to the second::! The lower surface of the feed dog 2 above the slightly U is in a state of being horizontal with respect to the cloth 3. 5 10 15 20 Next, as shown in Fig. 2(4), the upper feed shaft 9 is rotated in a predetermined direction, so that the upper and lower moving bodies 5 are lowered along the respective grooves of the upper and lower guide grooves 6, and are at the bottom dead center, thereby making the level The guiding body 12 is lowered, and at the same time, the upper feed horizontal axis 16 is reversed in a predetermined direction, and the horizontal moving body U is moved along the respective grooves of the horizontal guiding body 12 in the conveying direction of the cloth 3. At this time, since the horizontal moving body _ moves along each groove of the horizontal guide (four), the upper feed dog 2 is horizontally placed on the lower side with respect to the cloth 3, and the entire tooth portion of the feed dog 2 is pressed against the cloth 3, The cloth 3 is moved in the conveyance direction along the conveyance direction of the cloth 3, whereby the cloth 3 is conveyed in the conveyance direction. Further, as shown in the second (d) diagram, the upper and lower movable shafts 11 are raised in the predetermined direction by the upper feed shaft 9 and the upper and lower moving bodies 11 are raised along the respective grooves of the upper and lower guide bodies 6, thereby raising the upper and lower guide bodies 12, At the same time, the upper feed horizontal axis 16 is reversed in a predetermined direction, and the horizontal moving body U is moved along the respective grooves of the horizontal guide body 12 to the final retracted position. At this time, since the horizontal moving body u also moves along the grooves of the horizontal guide (4), the lower surface of the upper feed dog 2 is horizontal with respect to the cloth 3. Here, the upper feed dog 2 is attached to the connecting member 19 with respect to the thickness of the cloth 3, and is adjusted in the height direction to be mounted ', and the trajectory of the elliptical motion as shown in the third (_) is used. However, when the upper feed tooth is used 2 Pressing the picture in Fig. 4, when the thick part of the fabric is thicker than the thick part #3a of the cloth 3, the increase in thickness hinders the drop of the upper feed tooth 2 in the B-shaped shape L as shown in Fig. 5(a) As shown, the pin 21 is usually located at the lower end of the long hole, and the upper feed tooth 2 presses the thick portion of the cloth 3, as in the fifth_ It is shown that by pressing the _ potential magazine 2, the pin, the upper feeding branch 18, the connecting member D, and the upper feeding shirt are stopped at a position higher than the lowest point of the ordinary circular motion corresponding to the increase in the thickness of the cloth. During this period, the horizontal movement body is stopped in the same manner as the upper feed dog 2 or the like, and is stopped at the corner groove 12a of the horizontal guide body 12 at a position higher than the lowest point of the ordinary sugar circle movement corresponding to the increase in the thickness of the cloth. The motion in the horizontal direction is continued, so that the upper feeding tooth can be conveyed at a position higher than the normal point of the movement, corresponding to the position of S where the thickness of the cloth is increased, by the cloth 3, the surface. That is, the motion trajectory of the end portion deformed linearly below the ellipse gj as shown in Fig. 3(8) is taken. Also, the portion of the thickness of the portion of the green material 3 is not hindered by the drop of the upper feed tooth 2 Therefore, the spring 21 returns to the normal length, and the upper feed dog 2 also performs a normal elliptical motion. Thus, according to the present embodiment, the vertical moving body 5 and the horizontal guide body 12 are connected to each other. The guide body restricts only the horizontal direction of the horizontally moving body U of the horizontally moving body U in the vertical direction. Therefore, in the presser foot feeding device i of the present embodiment, the upper teeth 2 and the lower moving mechanism 7 and the horizontal are provided. When the driving of the moving mechanism 13 is performed in the circular motion, the lower surface of the upper feeding blade 2 is horizontal with respect to the cloth normally placed on the needle plate.
