Description of Invention (4) (Please read the note on the back? Matters before filling this page) onto the film. The film passes through two screen drums In this way, the arrangement of the two screen drums falls on its axis perpendicular to the plane of the film. The screen drum on one side of the film is simultaneously used as a bearing to apply to the other side of the film. The other screen drums drive the mixing wheel. It is advantageous for the screen drums to align with each other in the axial direction and the direction of the film. In addition, the shafts of the two screen drums can also be aligned so that they fall in the same plane. The pair of screen drums in the film direction is achieved by properly selecting the roll rate of each drum. In the lotus turn, the roll rates of the two screen drums are equal, so the two screens move in synchronization with each other. The printing screen is aligned relative to other printing screens (in the circumferential direction or in the direction of the lotus walking). You can choose different lotus moving speeds until the printing screens are aligned with each other. In this specification, "alignment" means that the openings of one screen are at the same time as the local surface coating is deposited, and the screens of other screens are equal in overlap. Each mesh usually forms a dot grid. However, other arrangements are possible, such as multi-line. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. In another specific example, the first and second screens are the same design. For example, two identical screen drums can be used. Since the same printing pattern is selected, it can be ensured that both sides of the film can produce a local surface coating that is equal in the overlap. However, it is also conceivable to use a screen with fewer meshes than the S-screen, and the two screens are not exactly the same. It is particularly beneficial if each screen drum is driven by a servo motor, which allows the two screens to be aligned in the direction of the film lotus. After arranging each deposition device in the direction of the film lotus, the device contains an arrangement for laminating both sides of the film, so it provides a method for manufacturing such as San-6-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) 501951 A7 __B7_ V. Description of the invention (5) Sheet-like structure of layers. For laminates, such as tulle, embroidery material, or woolen goods. According to the method of the invention, it is particularly advantageous to use the above-mentioned device for depositing a local surface coating on a film. However, other devices can also be used. Local coatings are deposited on both sides of the film according to the invention. The surface coating on both sides of the film is such that the depositions are aligned with each other in such a way that all two sides of the film are coated, and all two sides have uncoated sections. Thus, the partial surface coating on one side of the film is at least partially equal to the partial surface coating on the other side of the film in the overlap. According to the film of the present invention, it is advantageous to manufacture the apparatus and method in the form of a K-type. However, other methods and devices can be used for the production of such films. The film contains a localized surface coating on both sides. According to the present invention, at least a portion of the surface coating on the first side and the surface coating on the second side are equal in overlap. The film is then coated on all two sides with uncoated sections on both sides. In the present specification, at least one part is equal in overlap, which means that each coating section on the first side of the film is placed in the same position as the coating section on the second side of the film. However, it is also possible that there are other coating sections on the second side, so that it is beneficial for one side of the film to be more sticky than the other side, for example, there are more adhesion points; Make the points formed on one side of the film larger than the points on the other side of the film. The coating is preferably deposited into spots on the film. As the coating layer, for example, polyurethane can be used. Usually about 50 points are deposited on the surface of the film per square centimeter (cm2).

The plastic K is liquefied in the screen drums 6a, 6b, and is deposited on the surfaces 4a, 4b of the film W through the mesh holes 11a · lib, and becomes partial surface coatings 2a, 2b. Specific examples of the various coated films W according to the present invention are shown in Figs. 3a to 3c. According to Section 3a (i), for each surface area 2a which has been coated on the film W-face 4a, a coated surface area 2b of the same size is formed at the same position on the other surface 4b. The pattern of the coating 2a on the surface 4a is thus equal to the pattern of the coating 2b on the other side 4b of the film W in overlap. Fig. 3b shows each coated area 2b on one side 4b of the film tf, and a surface area 2a is formed on the other side 4a. On the 4a side, another surface area 2a is further formed. In Fig. 3c, the points 2a on one surface 4a of the film W correspond to the points 2b on the other surface 4b. However, the sizes of the points 2a and 2b are different. In the application under M, the term “substantially equal in overlap” includes specific examples such as 3a to 3c. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. A specific example of a modification of the device according to the present invention is shown in FIG. For the fact that the partial surface coating calendars 2a and 2b according to Fig. 1 are directly deposited on the film W by the screen drums 6a and 6b, they are instead deposited on the substrates Ta and Tb provided in Fig. 4. The plastic K, which becomes a dot grid, is added to the substrates Ta, Tb, and then deposited on the film W. The substrates Ta, Tb are designed as rollers. The rolling speed of the screen drums 6a, 6b and the rollers Ta, Tb is -10-. This paper size applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 501951 A7 B7_ V. Description of the invention (1 (please First read the notes on the back and then fill out this page) Synchronize with each other and with the speed of film W. In this, the screen drums 6a, 6b are aligned with each other, so that the local surface coating calendars of the mutually aligned layers can be achieved. That is, the two sides of 4a and 4b are substantially equal in the overlap. Of course, the roller-shaped substrates Ta and Tb can be replaced with a tape-shaped substrate described in CH 648 497 or CH 663 310. Figure 5 shows that 2 The enlarged printing drums 6a and 6b represent the deposition area of plastic K on the film W.

Each screen drum 6a, 6b is installed to roll around the axis Al, A2. In the screen drum The left side of 6a, 6b indicates the meshes 11a, lib. The meshes 11a of one drum 6a are opposite to the meshes lib of the other printing drum 6b, and they run on the same plane perpendicular to the axis A. The following represents Mesh holes 11a, lib, and (not shown) mesh holes 11a, lib are connected to the mine, which are arranged to run perpendicular to the axes Al, A1 in the plane 12. The design of the printing drums 6a, 6b is the same. Especially in Two printing drums 6a, -11- This paper size applies to Chinese National Standard (CNS) A4 specification (210 X 297 mm) 501951 A7 __B7_ V. Description of the invention () 6b is arranged with the same number of holes and equal number of holes Ha, lib. So the mesh holes 11a of the screen drum 6a fall on the same plane 12 as the mesh holes 11b of other screen drums 6b. The drums 6a, 6b can be moved along the axes Al, A2. The movement can be performed manually or by a motor. In Figure 7 (b), the cymbal structure G designed as a tri-calendar layer according to the present invention is shown. The film W is based on this The invention becomes an intermediate calendar. A first material Ma is laminated on the film W-plane 4a. A second material Mb is calendared on the second face 4b of the film W. The materials Ma and Mb are made of tulle, woven material, or woolen fabric, and are formed as a thin film material by coating a spot-shaped local surface on the thin film W. Because the surface coatings 2a, 2b on the surfaces 4a, 4b are aligned with each other, moisture can be prevented from passing through the intermediate interval between the surface coatings 2a and 2b. A specific example of a modification is shown in Fig. 8 in which the film is enlarged in cross section through two deposition mechanisms. The design of the first deposition structure 3a is the same as the previous one, and it essentially contains a screen drum 6 so that the plastic K can be deposited on the 4a side of the film W. Contrary to the specific example of the upper case, the second sputtering device 33 has a design using an engraving roller 36. The engraving roller 36 includes deep recessed portions 35, which are distributed on the surface of the engraving roller in the same pattern, such as the mesh 11 of the stencil 6a. The engraving roller 36 is turned over the bath eaves containing plastic K. The plastic is scraped off from the surface of the engraving roller with a scraping blade 34, so that the plastic K remains only in the recessed portion 35. Plastic is splashed across the surface 4b of the film W from the recessed portion due to contact. In contrast to the mesh 11, the recessed portion 35 forms a clearly defined reverse surface for the screen drum 6a. This will allow stable operation. -12- This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm) ---------------- Install i I (Please read the precautions on the back before (Fill in this page)
