Next, the operation of this cloth support device will be described with reference to the flowchart of FIG. First, the values of the first and second positions of the dotted lines 21 and 22 detected by the sensor 17 shown in FIG. 5 are input to a control device (not shown). The values of the first position and the second position are the first position 21 with the lower limit value within the allowable range of the length 9a of the shoulder edge of the sleeve 9 in order to overlap the armhole of the body with the shoulder edge of the sleeve 9. , The upper limit is set to the second position 22, and the sleeve 9 having a shoulder lip that deviates from the range between the lower limit position and the upper limit position is not used due to poor size. Then, the sleeve 9 is attached to the sleeve support which is smaller than the first position, and the controller determines whether or not the foot switch is turned on (step 1), and a foot switch (not shown) is turned on. , Control device is sleeve bar 8
As the outer surface of the _{1-8 10} forms a length of the first position 22 of the shoulder periphery of the sleeve 9, the rotation speed from the origin is input to the pulse motor 6 (Step 2). Then, it is determined whether the operation of the pulse motor 6 is completed (step 3), and when the operation of the pulse motor 6 is completed, it is further determined whether the foot switch is turned on (step 4), and the foot switch is turned on. When the signal is input to the control device, the cylinder 12 and the manipulators 13 _{1 to} 13 _1
The positioning mechanism consisting of ₇ is loaded (step 5). Here, all the values of the sensors 14 near the manipulators 13 _{1 to} 13 ₇ are read (step 6), the cloth covering the sensors 14 is scraped off by the manipulator 13 (step 7), and all the sensors 14 wipe the cloth. It is determined whether or not it is detected (step 8), and the sensor 14 is prevented from being covered with cloth. Until the operation is completed, a predetermined fixed time is measured by a timer (step 9), and then all the data of the sensor 14 is read again (step 10).
The manipulators 13 _{1 to} 13 ₇ are operated so as to be detected in step 4 (step 11). And all the sensors 14
After detecting the cloth (step 12), it is determined whether the sensor 17 at the lower end of the peripheral edge of the sleeve 9 is on (step 13). If the sensor 17 is off, the peripheral edge of the sleeve 9 is located at the first position 2
Since it is smaller than the size of 1 and is defective, the motor 6 is shrunk to the origin (step 14), and the attached sleeve 9 is replaced with another sleeve and the process returns to the start. If the sensor 17 is off, the step motor 6 is driven (step 1
5), to expand the mobile sleeve bar _{8 1-8 10} to the second position 22 (step 16). Then, it is determined whether or not the sleeve bars 8 ₁ to 8 ₁₀ have moved to the second position (step 17), and it is determined whether or not the sensor 17 is on (step 18), and the sleeve bars 8 ₁ to 8 ₁₀ are determined. If is moved to the second position before the sensor 17 is turned on, the size of the peripheral edge of the sleeve 9 is larger than the specified size, so the motor 6 returns to the origin (step 19) and the sleeve 9 is replaced and started. Return to. If the sensor 17 is not turned on before the sleeve bars 8 ₁ to 8 ₁₀ are moved to the second position, the driving of the motor is stopped (step 20) and the manipulators 13 _{2 to} 13 ₃ ,
By driving 13 ₅ and 13 ₆ (step 21) and pressing the peripheral edge of the sleeve 9, it is determined whether or not the driving of these manipulators 13 is completed (step 22). securing the sleeve 9 to the sleeve bar 8 ₁₀ clamps the needle 16 to the cylinder 15 is driven (step 2
3). Then, by comparing the size position is the most optimum size of the pre-sleeve the rotational speed of moving the sleeve bars 8 _{1-8 10} by a pulse motor 6 (step 24), the smaller the size position, the pulse motor 6 the driving sleeve bar ₈ 1-8
The size of ₁₀ is reduced (step 25), and it is determined whether the pulse motor 6 has been driven until the size position is reached (step 26). If the size position is larger, the pulse motor 6 is driven to drive the sleeve bars 8 ₁ to 8 _10.
Is enlarged (step 27), and it is determined whether the pulse motor 6 has been driven until the size position is reached (step 28). After that, the manipulators 13 ₁ and 13 ₇ are driven (step 29), and the manipulators 13 ₁ and 13 ₇ are driven as controlled in steps 6 to 11, and the sleeve 9
The manipulators 13 ₁ and 13 ₇ are controlled so as to press the peripheral edges of the sleeves (step 30), and the mounting of the sleeve 9 on the sleeve support is completed.

[Problems to be Solved by the Invention] However, when the sleeve 9 is mounted on the sleeve support as described above, the lower edge of the peripheral edge of the sleeve 9 in step 18 is set as shown in a solid line 9a in FIG. Only a few of them are located near the sensor 17 provided at the lower end of the body, and the peripheral edge of the sleeve 9 has various stigmas. Therefore, even if the upper end is fitted, the shape at the lower end is as shown by the solid line 9b. Often. With the shape as shown by the solid line 9b, the cylinder 15 is driven to clamp the clamp needle 16 as in step 22.
In case of fixing the peripheral edge of the sleeve 9 to the sleeve bar 8 _10, then step 23 to step 30 is performed by the cloth edge control operation is performed, even trying to positioning from the solid line 9b to the state of the solid line 9a, the clamp Since the needle 16 fixes the lower end of the sleeve 9, the lower peripheral edge of the sleeve 9 cannot move in the lateral direction in FIG. Accordingly, or surplus cloth edge after the fabric edge control in the vicinity of the manipulator 13 _1, also manipulator 13
_In the vicinity of ₇ , there is a problem that the manipulator 13 ₇ moves to cause abnormal tension on the peripheral edge of the sleeve 9.

As described above, in the conventional cloth supporting device, when the lower end of the peripheral edge of the sleeve 9 is fixed by the clamp needle 16, when the shape of the peripheral edge of the sleeve 9 has a peculiar shape, the cloth near the outer periphery of the peripheral edge of the sleeve 9 is removed. However, there is a problem in that the peripheral edge of the sleeve 9 cannot be accurately positioned due to excess tension or abnormal tension, which results in poor seam accuracy.
