[Industrial applications]

 This invention relates to a curtain to which tack is applied by ultrasonic welding.

[0002]

[Prior art]

Generally, the curtain is provided with a tack of an arbitrary size on the upper part of the curtain so that the folds look beautiful and uniform, and it is customary to form the tack by sewing. A hook for hanging the curtain rail is attached to the back side. In Fig. 1 (a), tacks (T ₁ ), (T ₂ ), ... are provided on the upper part of the conventional curtain (X), and a hook (H) for hanging on the curtain rail described later is attached to the back side thereof. It is embedded. FIG. 1 (b) is an enlarged view showing a state where the tack (T ₁ ) is provided on the front side of the upper part of the curtain (X). The hook (H) is inserted on the back side of the tack (T ₁ ). (M) shows a tack (T ₁ ) and a sewing part for obtaining a hook (H) insertion point. FIG. 1 (c) is a view showing the back side of the tack (T ₁ ), and the hook (H) is inserted into the hook (H) insertion part made by the sewing machine hooking part (M). Indicates the status. Figure 1 (d) shows the perforation of the sewing part (M), where sewing of the sewing machine starts from point (m ₁ ), passes through points (m ₂ ), (m ₃ ), and then reaches point (m ₄ ). , (m ₅ ), (m ₆ ), (m ₇ ) indicate that the sewing operation is completed. At that time, the perforations between the points (m ₄ ) and (m ₅ ) are slightly widened so that the hook (H) can be easily inserted later.

[Problems to be solved by the device]

 In this invention, when tacking the polyester curtain, without using a conventional sewing machine, an ultrasonic welding device is used for bonding, and a hook for hanging on the curtain rail is made of synthetic resin, and the ultrasonic wave at the time of tacking is applied. At the same time as welding, the objective is to obtain a curtain with this synthetic resin hook fixedly attached.

[0004]

[Means for Solving the Problems]

 The upper tack of the polyester curtain is tacked by ultrasonic welding, and the upper tack of the polyester curtain is tacked by ultrasonic welding.At the same time, a synthetic resin hook is inserted in advance. The curtain has a tack applied by ultrasonic welding, which is characterized by welding.

[0005]

[Action]

 The curtain to which tack has been applied by ultrasonic welding of the present invention has significantly reduced the number of steps for hooking a sewing machine on the top of the conventional curtain, saves labor, and the conventional hook insertion work is complicated. By replacing the material with a synthetic resin material so that it can be attached at the same time as tacking, a curtain that can omit such hook insertion operation itself can be obtained.

【Example】

According to the embodiment of this invention, the operation for imparting the tacks (T ₁ ), (T ₂ ), ... Shown in FIG. It is performed by welding. Figure 2 shows the ultrasonic oscillator (A), which has an ultrasonic horn (B) that moves up and down at the bottom of the ultrasonic oscillator (A). Therefore, an iron receiving jig base (C) is provided. On this receiving jig table (C), place the part that forms the tack in the polyester curtain at the position (K) shown in the figure, and lower the ultrasonic oscillating horn (B), and apply a pressure of about 50 Kg. Ultrasonic welding is performed by oscillating sound waves. The array shape (f) of the welding points on the tip surface of the ultrasonic oscillating horn (B) is the array shape (f) shown in Fig. 3, which is the welded part (M ') in Figs. 4 and 6 described later. Then, the welded portion is cured and formed. Since the array shape (f) is formed intermittently, it softens during curing. The array shape (f) in FIG. 3 is based on the perforation (M) for providing the conventional tack in FIG. 1 (d).

In this case, it is appropriate that the ultrasonic capacity is 1,800 W, the ultrasonic oscillation time is about 1.5 seconds, and the cooling time is 1.5 seconds. During this cooling time, the ultrasonic oscillation horn (B) is turned on. Raise upward to complete welding. Conventionally, the time required to provide a tack by sewing with a sewing machine is generally about 15 seconds, but when the ultrasonic welding of the present invention is used, the time is shortened to 3 seconds, and moreover, it is caused by the work of sewing with a sewing machine. Therefore, troubles such as sewing machine thread breakage can be resolved. In this way, the tack (T ₁ ) provided on the polyester curtain (X ₁ ) is provided by welding at the welding portion (M '), and the ordinary hook (H) shown in FIG. 1 (c) is provided on the back side thereof. Insert it into the curtain of this invention.

Next, in the present invention, instead of the conventional hook made of metal, a wire-like locking piece (E) is integrally formed on one of the synthetic resin long thin pieces (F) as shown in FIG. 'used, the tuck-forming portion of the curtain during the ultrasonic welding, the hook (H provided hook (H)' sandwich) the entire advance, subjected to ultrasonic welding tack formation and at the same time, a tack (T ₁₎ part The curtain (X ₂ ) of this invention is formed.

[0009]

[Effect of device]

 The curtain to which tack has been applied by ultrasonic welding of the present invention has significantly reduced the number of steps for hooking a sewing machine on the top of the conventional curtain, saves labor, and the conventional hook insertion work is complicated. By replacing the with a synthetic resin material, it can be attached at the same time as tacking, so that such hook insertion operation itself can be omitted, and a truly rational curtain is obtained.
