この考案は、布に直線の縫目線を形成するよう
に布を縫合部へ案内するミシンの布案内装置に関
する。[Detailed Description of the Invention] This invention relates to a cloth guide device for a sewing machine that guides cloth to a seam portion so as to form a straight seam line in the cloth.

内できずに使用不能となる欠点を生じた。 Conventionally, when forming a straight seam as described above, as shown in Japanese Patent Publication No. 56-45639, etc., the direction of the fabric feed through the needle is placed before the sewing machine sewing part in the fabric feed direction. It is known that a guide surface along the cloth feeding direction is provided on one side of the line, and a pressing means is provided to apply rotational moment by pressing the cloth so as to bring the edge of the cloth closer to the guide surface. The conventional method can only be used when forming a seam along a straight edge of the fabric along the fabric feeding direction, and can only be used when sewing fabrics with bent fabric edges or in a straight line in a direction that does not follow the edge of the fabric. When forming eyes, it is difficult to guide the eyes, resulting in a disadvantage that the method becomes unusable.
この考案は、上記従来のものの欠点を除去する
ことを目的とする。 This invention aims to eliminate the drawbacks of the above-mentioned conventional ones.

い。 This invention has the above-mentioned structure. When sewing starts from point P1 in FIG. , 27 is pulled, one end of the wire 15 is fixed, and the holding plate 7 is rotated around the spindle 5 by the connecting body 13 to pull up the tip side (gears 18a to 18h), and one end of the wire 27 is fixed. action plate 2
3 is rotated around the support shaft 21, and the guide portion 28a is located above the needle drop point and is inclined with respect to the cloth feeding direction. At this time, the locking position of the guide body 28 in the longitudinal direction of the elongated hole 29 is adjusted using the scale 31 so that the length l 2 (FIG. 1) is obtained. The scale 2 is adjusted so that the folded edge of the cloth W is aligned with the guide portion 28a of the guide body 28 and the length l 1 (FIG. 1) is obtained.
Place the cloth W using 0. As the presser foot 2 is lowered by operating the knee switch, the electromagnet is deenergized, and the retaining plate 7 is rotated again by the force of the coiled springs 10 and 11, and the teeth at the lower ends of the gears 18a to 18h are clamps the fabric W on the planned seam formation line, and the connecting plate 22 holds the support shaft 2 by the action force of the coiled spring 25.
The guide body 2 is rotated clockwise in FIG.
The guide portion 28a of No. 8 is separated from the needle drop point. After that, when the sewing machine is driven, the cloth W is fed forward by the cooperation of the presser foot 2 and the feed dog, and at this time, the cloth W in front of the seam is moved between the sewing machine and the bed surface by the teeth of the eight gears 18a to 18h. The gears 18a-1 are clamped together.
Due to the 8h rotation, movement of the cloth W in the cloth feeding direction is allowed, but movement in a direction intersecting the cloth feeding direction is restricted, and the cloth W moves straight. In this embodiment, the dart stitching that starts sewing from point P1 in FIG.
You may make it guide by 18h. Further, it may be carried out in straight stitches other than dart stitches.

が得られる等の効果がある。 As described above, according to this invention, the rotating body, which has a sharp edge on its outer periphery and is rotatably supported around a horizontal axis that intersects with the machine frame in the cloth feeding direction, passes through the needle drop area. Multiple locations are placed on the fabric feed direction line and in front of the needle drop point in the fabric feed direction,
By providing the outer periphery so that it can be pressed against the fabric, it is possible to move the fabric straight even when the edge of the fabric is bent or when forming a seam on a straight line in a direction that does not follow the edge of the fabric. This has the effect of making the seams neater, improving the quality of the product, and providing a versatile cloth guide.
