ができる。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an innovative design of a presser leg of a sewing machine and its adjusting device, and in particular, as a kind of a wide range of application, a stable smoothness of a charge can be secured to enable a good sewing of a sewing machine. This refers to the leg of a sewing machine and its adjusting device. It has multiple sets of rolls on a flat press leg, and the contact between the rolls and the sewn product ensures smoothness when the sewn product is charged, and the sewing machine is sewn without causing irregular charge or wrinkles. In order to obtain the effect of straightness and beauty, and the contact area of the present invention with the sewn product is large, therefore, the effect of holding the sewn product with a small pressure is obtained, and the roll leaves a trail on the surface of the sewn product. It's a perfect thing to secure the cost without. Separately fixed with one leg to one horizontal and vertical adjustment pedestal, you can hold the leg and adjust the front and back and left and right as needed, hold the leg and hold the sewing object at the most suitable position Thus, the progress of sewing can be made advantageous.

にしている。2. Description of the Related Art High leg sewing machines commonly used are all used for sewing leather. However, leather is thicker than ordinary clothing and requires a great deal of force to help the leather fee. Therefore, all of the press legs are mainly roll type press legs (as shown in Fig. 8), and there is point contact between the roll type press legs and the sewn product, so the sewn product can easily hold a large press force and a small charge resistance. With the strength, the sewn product can be smoothly charged at the time of sewing, which makes the progress of sewing advantageous.

質に大きく影響している。This type of roll type press leg can solve the disadvantages disadvantageous in sewing flat type press legs, but such a method still has the following drawbacks. Hold. 1. Since the roll and the sewn product are in point contact with each other and have a small contact area, the sewn product often leaves traces of the roll on the sewn product surface, impairing the perfection of the sewn product surface. 2. Since the sewn product and the roll are in point contact with each other, the sewn product has a high degree of freedom, it is difficult to maintain the charge direction, and it is difficult to maintain the straightness of the sewing machine. 3. Since the positions of the sewing needle and the crimping point change when the sewn product is sewn, the leather is easily pulled up when the sewn product is sewn, causing a jump needle phenomenon. 4. When sewing both needles, the position of the sewing needle is at the front and back, so that when one of the needles is sewn, the sewn product cannot be well pressed, and the loosening phenomenon of the sewing thread structure is formed. 5. Since the sewn product and the roll are in point contact with each other, it is easy for the charges to be irregular at the time of sewing, which causes the uneven density phenomenon of the sewing machine sewing, which affects the sewing quality of the sewing machine. All of the above are disadvantages that occur when the commonly used roll-type press legs are actually applied, which results in poor sewing quality of leather or thick sewing machines and greatly affects the quality.

することができる。又As shown in FIG. 1, the holding leg 1 and the head pedestal 2 are connected by a single pin 3.
In addition, one spring 4 is incorporated between the both, and the action of the spring 4 maintains the balance of the restraining leg 1 (this is the same technique as generally used), and one notch 5 is provided on one side of the restraining leg 1. The notch 5 is provided with a sewing needle 6 (see FIG. 2).
(See) the sewing site. When separately sewing with two needles, the other sewing needle 7 is located on the side 8 of the starting end of the notch portion 5. In this way, both sewing needles are used to hold down the effect when sewing, and the jumping needle phenomenon is exempted. The center of the first roll 9 is located at the center of the radial of the notch 5 and is locked with the pin 10, and thereafter, a plurality of rolls 11 are provided if necessary, and as shown in FIGS. Is pushed on the charge gear 13 by the rolls 9 and 11 when advancing the sewing operation, and when the sewing needle returns through the sewn product 12, the sewn product 12 is set on the roll sets 9 and 11.
Is kept stable and will not be triggered.
The sewing thread is smoothly tied up there. The roll sets 9, 11 and the sewn product 12 and the charge gear 13 form a surface contact. Therefore, the charge gear 13 is the sewn product 12.
When a sewing machine 12 is driven, a large force receiving area is obtained to promote the sewing product 12, and the surface contact with the sewing product 12 makes it possible to easily maintain the charge direction of the sewing product 12 and to easily hold the sewing machine in a straight and beautiful manner.

残すのを免除することが出来る。Referring to FIG. 4, one lateral adjustment pedestal 14 is connected to the head pedestal 2, and one lateral slot 15 is provided in the lateral pedestal 14 to provide the elongated shape. The hole 15 connects the horizontal adjustment pedestal 14 to the horizontal adjustment tank 18 of the vertical adjustment pedestal 17 through a single bolt 16 so that the horizontal adjustment pedestal 14 can be slidably fixed to the left and right in the horizontal adjustment tank 18. In this way, add to the adjustment of the lateral position. FIG. 5 shows a variation of the present invention, in which the lateral adjustment pedestal 1 is used.
By changing 4 (see FIG. 4) into one horizontal adjustment bar 19, and providing one adjustment sleeve 20 on the vertical adjustment pedestal 17 to provide for connection through the horizontal adjustment bar 19,
This also makes it possible to obtain the above-mentioned effect of the lateral adjustment. Separately, the present invention can also obtain the same effect by a method such as a tail base, a gear, etc., so abbreviated words here. Referring to FIG. 6, it is an actual layout of the present invention, in which bolts 21 are screwed onto the holding bar 23 through the elongated holes 22 of the vertical adjustment pedestal 17 (see FIG. 5) to smooth the holding legs 1. It can be bonded onto the bar 23. The spring 24 provides a pressure source for the hold leg 1. Since the present invention achieves a good hold-down effect with a small pressure, the volume 25 can thus be adjusted to reduce the pressure of the spring 24, excluding the hold-down leg 1 from holding-down marks on the sewing surface.

The force is reduced, the smoothness and straightness of the sewn material charge are secured, and the roll set does not easily leave traces on the surface of the sewn material, which is useful for improving sewing quality and performing sewing. In addition, since it is possible to secure the external appearance of the sewn product, it is an invention that has one reformation.
