Next, a method of using the curtain manufacturing apparatus 11 having the above structure will be described. First, this curtain manufacturing device 11
A procedure for cutting the fabric K by means of will be described. (1) First, with the clamp portion 14 lowered,
The upper end of the cloth K which becomes the curtain 1 is clamped by the clampers 21, 2
The clamp beam 18 is clamped by 1 ... Further, by rotating the handle 56, the height of the length measurement limit switch unit 55 is set in accordance with the height of the curtain 1 to be manufactured.

(2) In this state, when the raising switch (not shown) provided in the control portion 61 is pushed down, the worm motor 17 is rotationally driven and the clamp portion 14 is raised. When the clamp portion 14 is detected by the deceleration limit switch 55b of the length measurement limit switch portion 55, the rotation speed of the worm motor 17 is decelerated, and the upward movement speed of the clamp portion 14 is decelerated.

The cutting device 25 cuts the lower end of the curtain 1 between the rails 23 and 24 to make the curtain 1 a predetermined length. In particular, when cutting a thick cloth or the like, both sides of the lower end of the cloth K are clamped, if necessary.

(4) When the lowering switch (not shown) provided in the control unit 61 is pressed after cutting by the cutting device 25, the worm motor 17 is driven in the reverse rotation and the clamp unit 14 is lowered. . When the clamp portion 14 is detected by the lower limit switch 51, the rotation of the worm motor 17 is stopped and the downward movement of the clamp portion 14 is stopped.

Here, the curtain manufacturing apparatus 11 of the present embodiment
During the cutting operation according to the above (1) to (4), the stamp device 32 marks the surface of the cloth K clamped by the clamp part 14 near the upper end.

Next, the stamping operation performed during the cutting operation will be described. First, various necessary data are input in advance from an input unit (not shown) provided in the control unit 61. Here, various necessary data includes an end dimension L1 from the edge of the fabric K to the edge of the first fold, a desired width dimension L2 for finishing, a desired fold number N1, and a fold number N2 (Fig. 7). Here, the folds 2 have one fold, two folds, three folds, etc. as shown in FIGS. 8A to 8C, and in these cases, the number of folds of the folds 2 is N2 = 1, N2 = 2 and N2 = 3.

Then, with the cloth K clamped on the clamp portion 14, as shown in FIG.
To the origin O. In this state, the stamp device 32 is moved to the end of the cloth K in the direction of the arrow in the figure. At this time, the clutch 33a is released. In this way, the movement amount of the stamp device 32 is detected by the encoder 35, the total length L3 of the cloth K is obtained by the control unit 61, and displayed on the display unit (not shown) of the control unit 61. After the stamp device 32 has finished moving, it is returned to the clutch 33a.

Then, the control section 61 calculates the knob size L4 (see FIG. 7) of the cloth K required for making the fold 2 by the following equation, and displays the knob size L4 on the display section.

[0028]

## EQU00001 ## L4 = {L3-2L1-L2} / 2N2

Next, the control unit 61 controls the pitches P1, P2 of the marks 3, 3, ... Made on the cloth K based on the total length L3, the knob size L4 and the various data L1, L2, N1, N2.
(See FIG. 10) is calculated by the following equation.

[0030]

[Equation 2]

Then, in the above (1), the worm motor 1
If you push down the lift switch to rotate 7
The moving motor 33 is also driven to rotate, and the moving motor 33
The rotation of the stamp device 3 causes the stamp device 3 to rotate, as shown in FIG.
2 is moved in the direction of the origin O along the clamp portion 14.
At this time, the moving amount of the stamp device 32 is measured by the encoder 35, and the measured data is transmitted to the control unit 61.

Then, the controller 61 controls the encoder 3
When the position of the stamp device 32 is detected based on the measurement data from 5 and it is confirmed that the stamp device 32 has reached the center position of the fold 2 formed on the curtain 1, the moving motor 33 is provided. The clutch 33a is operated to turn off the transmission of the rotational force of the moving motor 33 to the belt 34 and drive the stamp device 32. That is, the rod 42 is projected by the cylinder 41 of the stamp device 32, and the stamper 44 provided at the tip of the rod 42 stamps the mark 3 at the center of the fold 2 formed on the upper end of the cloth K. It

Further, the number N1 of folds created by this operation
Is repeated, and the marks 3, 3, ... Are pressed on the upper end portion of the cloth K at predetermined pitches P1, P2 in the width direction (see FIG. 8). Then, the cutting work is completed, and the clamp unit 1
Marks 3 and 3 pressed on the upper end of the cloth K removed from
... as a reference, and folds 2, 2, ... Are created based on the knob size L4 displayed on the display unit of the control unit 61.

As described above, according to the curtain manufacturing apparatus of the above-mentioned embodiment, since the cloth K to be the curtain 1 is suspended, the lower end of the cloth K is cut in the width direction.
It is possible to surely match the set length when actually used, and it is possible to manufacture a good curtain 1 with no variation in length dimension.

Further, during the cutting operation for cutting the height of the curtain 1 to a predetermined size, the curtain 1 is extremely easily and automatically operated.
Marks 3, 3, ... Can be placed at the center of the folds 2, 2, ... Then, the folds 2, 2, ... Can be formed extremely easily with reference to the marks 3, 3, ... Attached to the upper end of the curtain 1.

That is, when the folds 2, 2, ... Are created, the marking work of the marks 3, 3, ... Three, three ...
It is possible to significantly reduce the labor and time spent for the stamping work, and it is possible to greatly improve the efficiency of the work for creating the folds 2, 2. Further, since the marks 3, 3, ... Are mechanically attached, the accuracy of the marking position can be increased, and a curtain in a good finished state can be manufactured.

In the above embodiment, the stamp device 32
Although the stamping operation to the upper end portion of the curtain 1 is performed during the cutting operation of the curtain 1, the stamping operation by the stamping device 32 may be performed separately from the cutting operation of the curtain 1.

Further, the folds 2, 2 ... Created on the curtain 1
In addition to the types described in the embodiments, there are single folds as shown in FIG. 12 (a) or box folds as shown in FIG. 12 (b). Needless to say, the curtain manufacturing apparatus 11 can be applied.

The specific construction and structure of the curtain manufacturing apparatus 11 of the above embodiment is not limited to the embodiment.

[0040]

As described above, according to the curtain manufacturing apparatus of the present invention, the following effects can be obtained.
According to the curtain manufacturing apparatus of the first aspect of the invention, since the lower end portion of the cloth used as the curtain is cut in the width direction in a suspended state, the set length during actual use can be reliably matched. Therefore, it is possible to manufacture a good curtain without variation in length and dimension. According to the curtain manufacturing apparatus of the second aspect of the present invention, the stamping device moved in the width direction by the moving device marks the center of the fold near the upper end of the cloth clamped by the clamp part. Therefore, the work efficiency can be significantly improved as compared with the manual work. Further, since the marking is performed mechanically, the marking position can be made extremely accurate, and a curtain in a very good finished state can be manufactured.
