Claims

[Scope of utility model registration request]

A cloth support that supports the cloth to be sewn by a sewing machine such as dart sewing, a moving means for moving the cloth support from a position away from the needle drop of the sewing machine to the needle drop position, and a cloth transferred to the needle drop. The fabric holding device is provided with an upper holding plate, a lower holding plate, and an opening/closing means for opening and closing the upper and lower holding plates, and each of the upper and lower holding plates is formed above the needle drop. It has a vertically penetrating groove and left and right pressing surfaces formed on both sides of this groove, and after the cloth transferred between the upper and lower pressing plates is pressed at once by the left and right pressing surfaces on both sides of the needle drop, the cloth is A cloth supply and press device for a sewing machine, characterized in that the support is moved back and only the cloth is clamped and pressed from above and below by upper and lower press plates.
