The so-called initialization refers to the removal of the droplets in the mold (die, which may be dried and hardened, so that the η:: to be coated will result in bead formation). In the case of hardening of the condition, it will also be used for this reason. The industry has proposed various types of coatings (coating liquids) that are initialized at the front end of the mold before the coating. The top surface of the coating member is biased to make it close to the cleansing member (thin), and the cleaning structure is in a shape that can be closely attached to the front end portion of the sleeve portion, and is made of a polymer resin having a rotational elasticity. Then, the lip portion of the member (10) is moved to remove the adhered paint (coating liquid, droplet) 5 1323193 to the cleaning method (please refer to the patent document . A method of hardly scraping off a lip portion which is in contact with a mold body to remove a coating liquid held at a lip portion (refer to the patent document 'However, in this method, when the amount of liquid droplets is relatively large, especially dry hardening Feeling oblique if the job is dripping from the mold If the front end is completely removed, it is necessary to apply some degree of pressure to find these cleaning counties or the two together called the scraping device to move. Therefore, by scraping with the mold, these scraping The device is a three-loss device. The fine powder that has been removed by the wear-removal _ will be attached to the surface of the front end of the mold, and will be attached to the front end of the mold. a. If it is coated in this state, When the liquid is discharged, the 3 is peeled off, and when the surface of the coating film obtained by coating is fine, sometimes the monomer dissolved in the coating liquid is mixed, and the composition is different in the coating film. In addition to the method of m, etc., there is also a method of making the mold secret without contact with the mold itself. For example, the method of initializing the pre- iff front end by pressing the drum-shaped object ( Please refer to Patent Document 3) At this time, at the same time, foreign matter at the front end of the mold can be removed. Among the methods, since the scraping device or the like does not directly contact the mold during initialization, it can be A coating film having a relatively small foreign matter is obtained. However, since the original purpose of the method is to remove the foreign matter in order to be trimmed, the foreign matter is completely aged, and the coating is continuously applied to the roller-like object. By the way, if you use this method, the foreign matter on the coated film after completion will be attached, and it will be borrowed. Especially when the material is on the side of the mold (to be dyed &5; At the time of the 'in-stage period, foreign matter will continue to adhere. 'Also, at each initialization, the paint will be cleaned and reformed from the front end of the mold, but it will be coated on the drum 1323193. The material 'can't be in the material, re-recorded, and then the whole material, the object's physical state of the coating material (4) will be attached again from the reliance, even after a long period of use, in the spout: dry, state substance adhesion Therefore, it is difficult to perform initialization and some dry matter and solid matter tend to peel off and become a lining. In view of the various reasons described above, it is not possible to obtain a type that can be sufficiently satisfied without the attachment of foreign matter, and the mode is = technology. Therefore, it is necessary to stably obtain a non-connected mold front end of the coating material which has a very small amount of foreign matter, and a technique of blushing & This technique is used to soak the front end of the mold or contact it in a container, etc., and slowly rise it when it is used (please refer to the patent 'n non-contact type mold front end initialization method) The initialization method of the other end of the nuclear instrument is still not a ruthless decision.
