These are sandwiched, bent in the same manner as in FIG. 11A, accommodated in the aluminum frame 13, and fixed with a string or the like. Then, a plurality of such kraft papers and the first and second curtain fabrics accommodated between the three kraft papers are prepared in the aluminum frame 13, which are accommodated in the pressure kettle, and subjected to the steaming process. do. This process is the same as (I).
[0049]
Through the above processing, the shell-shaped pleating process of the curtain fabric is completed. Thereafter, the same processing is repeated.
[0050]
In the above processing, the size of the three kraft papers is slightly larger than that of the first and second curtain fabrics as in the case of the “cigarette case type”.
[0051]
(C) Manufacturing method of urethane material 12 Next, the manufacturing method of the urethane material 12 of the above shapes is demonstrated. In this production, an apparatus as shown in FIG. 12 is used. The movable table 21 accommodates the quadrangular prism type urethane member 20. The movable table 21 is placed on a fixed table (not shown) and is slidable in the longitudinal direction of the movable table 21. The both ends of the heart-shaped heater 22 are attached to the fixed base as shown in FIG. The moving table 21 is vacant so that the bottom surface portion thereof does not come into contact with both end portions of the heater 22 during movement. The heater 22 can control the power supply by the slider 23. Further, as shown in FIG. 13B, the heater 22 has a strip shape, the width is about 10 mm, and the thickness is about 1 mm. Further, each end of the heater 22 is covered with an insulator 24. Further, the intersecting portions of the heaters 22 are provided with a difference in the front-rear direction so that they do not contact each other.
[0052]
A method for manufacturing the urethane material 12 using such an apparatus will be described. When the moving base 21 moves in the direction of the arrow in FIG. The urethane member 20 processed in this way has a heart shape by bonding two so-called tear-shaped cross sections. Therefore, when the center of the urethane member 20 thus formed is cut by a band knife (steric cutting machine) 26 as shown in FIG. 14, two urethane members 12 having the same shape are formed.
[0054]
(C) In the above, among the three craft papers, the craft paper 1a corresponds to the first pattern paper, the craft paper 1b corresponds to the second pattern paper, the remaining craft paper corresponds to the third pattern paper, and one third pattern paper. However, this may be two or more. However, it is necessary to change the steaming heat treatment time, temperature, etc. according to the number of sheets when manufacturing the pattern, and when pleating the curtain fabric using these patterns, the same depending on the number of sheets. Adjustment is required. Further, the pleating may be performed without using the third pattern, that is, the curtain cloth is sandwiched only between the first pattern and the second pattern. In the above description, the fabric is a curtain fabric, but pleating using these patterns is generally applicable.
[0055]
(III) Features of the above-described “shell type” pleating method are as follows.
(A) Example of curtain fabric (target material) that can be pleated [0056]
