400 and so on are some cases. But all these ultrasonic waves have one thing in common, that is, they do not have the ability to adjust according to the variable thickness of the webbing to be cut. Therefore, especially when they are cutting labels made from fabric tape, the result of the cutting is that they are products ranging from bad quality to unusable quality: W EP-AG 532 865 The method described is to correct the above-mentioned shortcomings by f-test, that is to set a pre-densifier at the front of the cutting knife. Wealth and ultrasonic domain devices are common, and will be cut _ the webbing will be thinned before cutting. But the result is that the adjustment of this pre-densifier is very difficult. Έ is either too little pre-densification or excessive pre-densification and cut the webbing. The task of the invention is to design a supersonic device of the kind described at the beginning of this article so that it can easily cut webbing of different thicknesses. This task is to apply for patents by means of new inventions The feature in No. 0 is achieved. Since the cutting blade is designed with different sections along the blade, when cutting, the appropriate thickness of the webbing is selected appropriately ^ applicable (210X25 ^ 公 Jt-^-( Please read the precautions on the back and then fill out this page)-* B7 B7 Printed by the Beigong Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 5.

With the ultrasonic device of the present invention, regardless of whether the cut webbing has a very thick or very thin position, it can be read very well. The cut edge of the webbing it cuts out Tightness is not easy to make hair, and the cutting edge itself has no fluff, and there will be no discoloration. It is expected to be only firm and strong, and at the same time, there is a lot of soft and secret money. Texture. This ultrasonic device not only enables the webbing to be processed to have many excellent characteristics, but also improves its self-reliance, especially for cutting knives and stone blocks. In this way, it improves the ultrasonic equipment_ Benefits, but also form a more favorable ratio of price and function. This ultrasonic device is suitable for cutting and welding a variety of webbing, whether the latter is knotted, knitted or woven, there is no problem . Even if the webbing has only a uniform thickness over its entire length, but because the ultrasonic device can be easily adjusted to fit the thickness of the webbing, it has brought benefits.

Printed by the Ministry of Economy, Central Standards and Administration of the Ministry of Economy, Labor, Consumers and Consumers Cooperatives A7 B7, commendation note (3.) The more point is that it can be used on the webbing whose thickness has been constantly changing due to the relationship of the pattern over its entire length. This situation occurs especially when multiple label tapes are woven together side by side to become a wide-width fabric, and then the wide-width fabric is cut to become the respective label tapes. At this time, the ultrasonic device can be used independently of the weaving of the webbing. However, it is more advantageous to directly set 14 ultrasonic devices in the production of weaving equipment, especially within the framework of the textile machine. Particularly advantageous embodiments of the present invention are described in Items 2 to 17 of the patent scope of the present application. First of all, of course, we can combine the ultrasonic oscillator with the anvil block and use it with the matching σ ', but it is more advantageous to use the ultrasonic oscillator and the cutting patch together with the stand block. In addition, each of the cutting blade and the stone block is equipped with an ultrasonic vibration = 〇 As described in the second item of the patent application, the side _-shaped surface 'is more advantageous, but U It is designed as a straight side as described in the three items of the Chinese patent application. The advantage of 2 can be as described in item 4 of the application file, and it has sharpness. Item 5 is edited as described in paragraph 5 of the patent application. Because of its quality, it can be used to dissolve the melted fabrics. It is especially advantageous to design it according to the method of the patent application No. (2).

Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs. Because of the smaller wedge angle, it is easier for thicker webbing to cut through the webbing knife. For thin webbing parts, it is more advantageous when the blade is larger. The latter enables the fast-passing webbing to be transmitted, and the wide sweeping and interpolating domains, so that the cutting rate will not be too fast, and at the same time, you can get a bright edge that is more obvious. In this way, the thinner webbing can reduce the amount of melted edges and can be leveled. · Basically, the cutter can be made into a straight cut as described in item 7 of the patent application scope, and the station block can be advantageously formed into a slightly curved shape so that the webbing will not be caught when passing through. In order to enable different parts of the cutting knife to be used, the cutting knife can be moved back and forth relative to the anvil block in the direction of the cut. Alternatively, the cutting blade can be moved without moving the anvil block along the incision. It is more advantageous to make the anvil block immobile as described in item 8 of the patent application scope, but it is more advantageous to make it into a rotatable circle as described in item 9 of the patent application scope The tube shape 'latter rotates as the webbing passes. The advantage of this type of anvil block is that it has a larger area of action, that is, the peripheral surface of the entire cylinder is scrambled, and the life of the anvil block can be greatly increased. In addition to this, this method is relatively gentle on the webbing itself, because the latter does not have to cause friction on the stationary bottom area during being cut and melted. As mentioned above, an ultrasonic oscillator is installed on the cutting blade and / or anvil. It is meaningful to apply the method described in item 10 of the patent scope like this. A more advantageous design of ultrasonic vibrator is described in item 11 of the patent application.
