るように動作して布を折りたたむ。 The folding means C includes a presser foot 17a and an elevating body 17 which is movable up and down with a predetermined stroke via an air motor (not shown), although not shown in detail.
It consists of b. The presser foot 17a is the lifting body 1.
The lifting body 17b is supported by a spring force so that it can move vertically relative to the presser foot 7b, and the relationship between the lifting body 17b and the presser foot 17a is normally as shown in FIG. 3. From this state, the lifting body 17b is When lowered to the lowest level via the air motor, the presser foot 17a engages with the upper surface of the workbench 4, and the presser foot 17a moves slightly upward against the spring relative to the elevating body 17b, thereby sewing. Sometimes, even if the thickness of the beading fabric P changes, the beading fabric P is always lightly pressed and held on the body fabric W, and the beading fabric P is caused by friction with the fabric when the needle pierces or comes out of the beading fabric P.
It acts to prevent flapping. Further, needle holes 18, 18 are formed vertically in the presser foot 17a, opening at the front end in the cloth feeding direction and facing the needle of the sewing machine A. The cloth transfer means B and the cloth folding means C operate as detailed in Japanese Patent Application Laid-Open No. 185887/1987 to fold the cloth.

御するようにしていた。 And in such a device, the section l 1 at the beginning of sewing
When sewing, for example, the main shaft of the sewing machine is rotated once in order to activate the needle bar stop mechanism so as to switch the left needle bar from the rest state to the operating state, or the cloth transfer means B is moved from the standby position to the ready position. Since operations such as moving the connecting rod 19 and connecting the connecting rod 19 to the transfer table 11 (support body 21) by applying the air cylinder E3 must be performed before starting sewing, conventionally the flow shown in FIG. I tried to control it according to the chart.

するようにしていた。 In other words, when the sewing machine is stopped at the needle-up position and a start signal is generated due to manual operation of a pedal, etc., the thread tension device is released (to prevent the thread from falling out of the needle at the beginning of sewing). After letting out a predetermined length of thread from the thread supply source, the thread tension device is closed again, and the sewing machine motor 1 is started after the cloth folding means C is placed in the lower position and the welt cloth P is folded as shown in Fig. 3. Then, with both needle bars 3 at rest in the upper position, the main shaft of the sewing machine is rotated half a turn, and as the main shaft of the sewing machine rotates half a turn, the left needle bar 3, which should be at rest, is held at rest. The stop mechanism acts to release the lock of the right needle bar 3 and set it to the operating state, and once the sewing machine motor is stopped at the main shaft rotation angle corresponding to the needle up position. Then, after moving the cloth transfer means B from the standby position to the preparation position, the air cylinder E 3 is activated, but after the air cylinder E 3 is activated, the connecting rod 19 is securely locked to the support body 21. Air cylinder
A "grasp stabilization time" is required depending on the operating time of E 3 , etc., and after this "grip stabilization time" has elapsed, the sewing machine motor 1 is restarted, and the "ball" is adjusted in relation to the rotation angle corresponding to the next needle down position. I was trying to start the "Edge Stitch Routine".

業能率を著しく低下する欠点を生じた。 Therefore, in the past, before actually starting welt stitching, it was necessary to rotate the main shaft of the sewing machine once and then stop it once, and then restart the sewing machine after the "grasp stabilization time" of the connecting rod had elapsed. This resulted in a drawback that significantly reduced work efficiency.
