[Problems to be solved by the invention However, in the conventional proposals such as the above,
As shown in FIG. 4, an enlarged sectional view of the holding portion, the ball box 31 placed on the body fabric 30 on the table 2 is pressed from above by the weight of the upper cloth substrate 3. Therefore, the upper surface of the upper cloth 31 of the upper cloth substrate 3 and the folding plate 27
There is a gap G between the lower surfaces of the ball box 31
Since no pressure is applied to the sewing machine, the beads and the cloth 31 are sent together substantially only by the frictional force with the body material 31 when being transferred to the needle drop position of the sewing machine.

However, at this time, since the upper cloth substrate 3 does not move and is in a stationary state, there is also a frictional resistance between the surfaces of the ball box 31 (this core material if there is a core material 32), the upper cloth substrate 3, and the binder 3a. acts to separate the ball box 31 from the body fabric 30 being transferred. In order to reduce this resistance, the upper cloth substrate 3
The surface is treated with PTFE (e.g. "°Teflon"), but depending on the fabric quality of the body material 30 and ball box 31, it may take some time before the large presser P and work cloth reach the needle position. This causes the ball box 31 to shift, causing the exact sewing position and the cutting position of the knife to shift, which not only impairs the quality of the sewing product, but in the worst case, there is a possibility that the workpiece will be defective. In addition, if the fabric is easily sewn, if it is sewn in a state where it is slightly stretched due to the am resistance between the table 2 and the upper fabric substrate 3, the elasticity will recover after the sewing is completed and shrinkage will occur.
“The puckering phenomenon sometimes degraded the quality of the sewing product.

[Means for solving the problem] Therefore, in the present invention, a means is provided to lift the upper cloth substrate until the large presser foot and the workpiece reach at least the needle position, thereby releasing the pressure due to the weight of the lower surface of the upper cloth substrate. The above object is achieved by pressing the ball box between the upper surface of the upper cloth substrate and the folding board surface, and forcibly sending the ball box by the frictional force.

[Function] With the above configuration, the ball box is forcibly transferred to the needle drop position without any displacement, while the valve fabric is fed by the pressure of the body clamp, and the pattern needle is also moved at the needle drop position. After the stitches are formed, pressing of the ball box is no longer necessary. As described above, it is possible to prevent poor sewing quality due to misalignment of the ball box or puckering.
