図中２点鎖線で示したように立上り。The tatami edge sewing machine has a sewing machine body (2) that can move forward and backward on a rail (1), a sewing needle (3), a hook part (4), and a flat stitch presser foot (5). In addition, a tatami width cutting device (6) is provided. When cutting the edge of the tatami floor, it is better to cut it with an inclination of 3 to 10 degrees (usually 4 to 6 inches) with the front side of the tatami mat slightly protruding from the conventional method.
As shown in the figure, the tatami floor cutting blade (7) is installed on a slope (
α) is tilted by 5°. This tatami floor cutting blade (7
) has a roughly triangular blade that is pivoted so that it can make fine reciprocating movements (oscillations) at high speed.
The tatami floor (8) is cut as the sewing machine body (2) moves. When cutting the tatami floor, special care must be taken when cutting the edge corner of the tatami surface just before the cutting is finished. This part becomes twisted due to the weight of the cut end of the tatami mat, making it difficult to cut it properly. Therefore, in this device, the hook part (4) of the sewing machine is located in front of the cutting blade (7).
) is provided with a pick-up blade (9) that can rise further forward in the cutting direction. When the cutting of the tatami floor (8) approaches the end, this pick-up blade (9) is activated by the operation of the cylinder (10).
It rises as shown by the two-dot chain line in the figure.

丁を手で操作して同様の切断をしていた。The sewing machine body (2) moves in the opposite direction to cut the edge corner of the tatami surface. After this cutting operation is completed, the sewing machine body (2) moves forward again and the tatami floor cutting blade (7) completes the cutting. Previously, similar cuts were made by hand using a knife called a pick-up knife.

の進行面と同一面内となるよう取付けている。This vertical movement is caused by a cylinder (12) provided at the top. The tatami surface cutting blade (11) is located at the lower surface of the flat stab presser foot (5), and the tatami surface cutting blade (7) is located forward in the direction of travel from the position of the sewing needle (3).
It is installed so that it is in the same plane as the plane of travel.
