る。2. Description of the Related Art For example, in a sleeve, an operator holds the both side edges of a cloth piece cut out from a cloth or the like, folds the same in two and supplies it to the needle drop of the sewing machine to remove the both side edges. It can be seen that both side edges of a piece of cloth that is sewn or folded in two are pressed and conveyed by a conveyor belt or the like and supplied automatically in synchronization with the sewing machine (Japanese Patent Application No. 62-331596). .

るという等の問題点があった。By the way, it is necessary for the operator to be skilled in order to feed both sides of the dough piece while holding it in the hand, and when feeding both sides by pressing them with a conveyor belt or the like. However, there is a problem in that it is difficult to align the both side edges on the conveyor belt, and it becomes more difficult especially when a long piece of fabric such as long sleeves is used.

る。 As described above, according to the present invention, the dough length of the dough piece is
Dough supplied on a table having a length equal to or larger than the size
The piece is pressed and conveyed by the conveyor belt, and the tip of the cloth piece is
If it is detected by a phototube installed at the rear of the thin film, the same transfer will be performed.
The belt retracted to the upper position and was fed onto the fixed piece.
The last edge of the dough is pressed and gripped by the swinging piece.
By this, the preparation system for sewing is prepared. Such a state
With the start of the sewing machine,
Position the mouse in the direction perpendicular to the fabric feeding direction.
As a result, the pieces of cloth are sewn reliably. Further
The last edge of the fabric is crimped and held via the mouse
Prevents the dough from coming off the mouse, and
Moves to the sewing machine position in synchronization with the sewing machine feed speed
By doing so, the mouse itself has a dough edge control mechanism and a dough piece.
The gripping and conveying mechanism of the dough is added,
Straight across the length of the fabric to the edges, and
The effect of automatically sewing the side edges of the material is obtained.
