BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewing machine presser for winding cloth for sewing products.

[0002]

2. Description of the Related Art As a sewing machine presser for winding cloth for sewing products,
There is a three-roll presser for three-roll sewing (see Fig. 5 ) that folds the end of the fabric into three and sew it on. The three winding presser 2 1, the presser body 23 which is fixedly attached to the sewing machine, rolling guide unit 2 for guiding to entangle the end of the fabric
4, the receiving portion 25 to stabilize the state entrainment and responsible for the ends of the wound is Ru fabric is integrally formed, three winding retainer 21
The the rolling guide unit 24, Ru Tei guide piece 26 for three rolled seam is provided.

[0003]

An invention is the way, when Ru three winding sewing chair the ends of the fabric, the presser 2 1, although the feeding dough in the direction of arrow B, at the beginning sewing, the feed Is very difficult (especially when sewing the hem of a shirt, especially since the front part of the shirt is folded back.) is there.

Further, when the cloth is overwound or the cloth is not wound enough while sewing the cloth, there is a problem that the receiving portion 25 becomes an obstacle and the correction cannot be easily performed on the way. is there. Therefore, an object of the present invention is to provide a sewing machine presser for cloth winding sewing, in which it is easy to set the cloth at the beginning of sewing, and moreover, it is easy to correct the cloth when it is wound too much or when the cloth is not wound enough. To do.

[0005]

The technical means taken by the present invention to achieve the above-mentioned object is to guide the end portion of the cloth in three windings to the presser body 2 which is fixedly mounted on the sewing machine. Plan
The inner piece 10, in the fabric winding sewing sewing machine presser and a receiving portion 14 to stabilize the state entrainment and responsible for the ends of the wound are Ru fabric, fixing the guide piece 10 in the retainer body 2, Receiving
The part 14 is separated from the holding body 2 and the receiving part 1
4 can be pushed to the main body 2 and separated laterally from the guide piece 10.
It is in the point that I supported .

[0006]

When the sewing start portion of the cloth is set on the presser foot 1, the receiving portion 14 is separated from the guide piece 10 , and in this state, the sewing start portion of the cloth is rolled into three windings and set on the guide piece 10 . Then, the receiving portion 14 is brought close to the guide piece 10 and returned to the original position. In addition, when the fabric is overwound or the fabric is not wound enough while sewing the fabric, the receiving portion 14 is also proposed.
When the receiving portion 14 is separated from the inner piece 10 , the receiving portion 14 does not become an obstacle and the resetting can be easily performed.

As described above, the receiving portion 14 is connected to the guide piece 10
By separating the cloth from the cloth, it is extremely easy to set the sewing start portion of the cloth and the midway correction when the cloth is over-wound.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 to 4, reference numeral 1 denotes a three-roll presser, which is mainly composed of a presser body 2 and a detachable body 3 which is detachable from the presser body 2. At the rear part of the presser body 2, there is provided an attaching part 4 which is attached and fixed to a presser bar provided on the sewing machine so as to be movable up and down through attaching screws, and from the lower end of the attaching part 4,
A pressing portion 5 for pressing the cloth from above is extended forward, and a needle hole 6 for inserting a sewing machine needle is formed in the pressing portion 5. A support wall 4a is provided on the lower right side of the mounting portion 4 so as to project rightward.

At the front portion of the pressing portion 5, there is provided a winding guide portion 7 for guiding the end portion of the cloth to be wound into three folds. In the winding guide portion 7, a cloth feeding portion 8 is cut out on the inner side in the left-right direction, and a support portion 9 is provided on the outer side.
A guide piece 10 is arranged in the dough feeding section 8. The guide piece 10 is formed in a spiral shape from a spring plate, and guides the end portion of the cloth fed into the cloth feeding portion 8 to be folded in three. The end of the tri-folded material is fed to the lower surface side of the pressing portion 5 and fixed by sewing.

An L-shaped plate 11 is screwed onto the support portion 9, and the guide piece 10 is fixed to the inside of the front end of the L-shaped plate 11 so that the guide piece 10 can be replaced. . Further, the rear right end of the L-shaped plate 11 projects above the separating body 3 and serves to reinforce the separating body 3. At the rear part of the separating body 3, the pressing body 2
Is provided so as to sandwich the support wall 4a of the support portion 12a. The support portion 12 is provided in a U-shape. The support portion 12 and the lower wall of the support portion 12 penetrate the upper wall portion of the support portion 12 and the support wall 4a from above. The separating body 3 is rotatably attached to the holding body 2 around a vertical axis of the set screw 13 by a set screw 13 screwed to the portion.

The separator 3 is formed along the press body 2, is located in the front of the cloth feeding portion 8, and receives the end of the cloth wound by the guide piece 10 from the lower side. In addition to the provision of the receiving portion 14 for stabilizing the roundness, the knob 15 for facilitating the rotating operation of the separating body 3 is provided. The receiving portion 14 is provided with a needle 16 for assisting the winding of the cloth.

In the above structure, when the sewing start portion is set on the presser foot 1 when three-winding is sewn, first, the presser foot 1 is retracted to the upper position and separated as shown by phantom lines in FIG. The body 3 is rotated about the axis of the set screw 13 to separate the receiving portion 14 from the winding guide portion 7. Next, the sewing start portion of the material A is wound into a tri-fold shape and positioned below the presser body 2, and the presser 1 is lowered, so that the wound portion of the material A is spirally wound on the guide piece 10 of the winding guide portion 7. Located inside.

Thereafter, the separating body 3 is rotated to move the receiving portion 14
To the original position shown by the solid line in FIG. With the above operation, the sewing start portion is easily set. Further, when the cloth is over-wound or when the cloth is not sufficiently wound while sewing the cloth, the catching state is easily corrected by moving the receiving portion 14 away from the winding guide portion 7. You can

Further, even when the guide piece 10 is deformed,
By separating the receiving portion 14 from the winding guide portion 7, the receiving portion 14 can be easily repaired and adjusted (since the receiving portion 14 does not become an obstacle). The guide piece 10 may be sandwiched between the support portion 9 and the L-shaped plate 11 or may be welded to the support portion 9 .

[0015]

EFFECT OF THE INVENTION According to the present invention , a guide for guiding the end portion of the cloth into three windings is provided on the presser body 2 which is attached and fixed to the sewing machine.
A piece 10, the fabric winding sewing sewing machine presser and a receiving portion 14 to stabilize the state entrainment and responsible for the ends of the wound are Ru fabric, fixing the guide piece 10 in the retainer body 2, receiving Department
14 is separated from the holding body 2 and the receiving portion 14
Is supported on the presser body 2 so that it can be laterally separated from the guide piece 10.
By holding the receiving portion 14 away from the guide piece 10 , it is possible to set the starting portion of the material for sewing very easily. Moreover, when the material is overwound while sewing the material, When the fabric or the fabric is not fully wound, the rolled state can be easily corrected. Further, it is possible to perform the repair and adjustment of the deformation of the prior SL guide piece 10 very easily.
