The present invention provides a method of making a louver of a horizontal blind, and a louver made by the method. The louver comprises a substrate having a front surface and a back surface. The front surface includes a first longitudinal edge, a second opposing longitudinal edge, and three adhesive regions. Each adhesive zone extends in the longitudinal direction of the louver. In one embodiment of the invention, the first, second, and third adhesive regions define two elongated blank regions that have no adhesive on the front surface to form the bonded through holes. In another embodiment of the invention, a method of forming a louver of a horizontal louver is disclosed. The method comprises the steps of: providing a substrate having a front surface having a first longitudinal edge, a second opposing longitudinal edge, first, second and third strips of adhesive regions, in sequence a longitudinal edge is arranged to the second longitudinal edge and forms first and second blank regions not containing the adhesive; the first longitudinal edge of the front surface is folded along the central axis of the first blank region to the second longitudinal surface of the front surface a rim such that the first adhesive region and the second adhesive region are combined to form the first elongated through hole; and the second longitudinal edge of the front surface is folded along the central axis of the second blank region The first longitudinal edge is such that the third adhesive region contacts the first longitudinal edge that is folded over and forms the second elongated through hole with the second blank region. -5- (3) 1276733 [Embodiment] The present invention provides an improved method of forming the louver 50 shown in Fig. 2 and the formed louver. The louver 50 according to the present invention can be easily and quickly combined, can be economically advantageous, and at the same time, is highly competitive in the market. In one embodiment, a louver substrate 20 for forming the lining according to the present invention is as shown in FIG. Show. The substrate 20 is made of a heat-treated louver material from a woven fabric, and a woven fabric can be optionally applied to the sheet. The woven fabric may be natural (e.g., silk, cotton, wool, etc.), or a synthetic product, and the woven fabric may be treated with a known fire retardant dye or water repellent, dustproofing agent, UV stabilizer, or the like. In one example, the substrate is a venetian woven fabric using natural or synthetic fibers and is immersed in the steps of impregnation, pressure stretching, slitting, heating, etc. as shown in Taiwan Patent Publication No. 1 79 031. form. Substrate 20 includes a front surface 22 and a back surface 24. The front surface 22 includes a first longitudinal edge 23, a second longitudinal edge 25 opposite the first longitudinal edge, and second, third and third elongated adhesive regions 26, 27, 28 are sequentially arranged by the first longitudinal edge to The second longitudinal edge 24 is formed with first and second blank areas 30, 36 that do not contain an adhesive. Each of the blank areas 30 and 36 has a central axis 3 2, 3 8 extending in the longitudinal direction of the substrate 20 . The manner in which the adhesive is applied to the front surface 22 can be carried out by any known method, for example, by a roller and a doctor blade. Preferably, the adhesive may be a hot melt adhesive such as a PU adhesive. In the embodiment of the substrate 20 shown in Fig. 3, the three adhesive regions 26 -6 - (4) 1276733 2 7 and 28 are arranged side by side along the longitudinal edges. In the preferred embodiment, the adhesive region 26 is applied with an adhesive. However, it should be noted that the region 26 may not be applied with the adhesive' while the width of the adhesive region 26 is selected as long as the first longitudinal edge can be fixed to the second adhesive. Fig. 4 and Fig. 2 show a method of the louver 50 according to the first embodiment of the present invention. As shown in Fig. 4, the substrate 20 is folded along the central axis 32 of the blank area 30 (Fig. 3) (Fig. 3), and the second longitudinal edge of the front surface is folded from the front first longitudinal edge 2 3 The edge 2 5 is such that the first region overlaps with the second adhesive region 27, and the first elongated through hole 40 is formed by the folded first blank region (Fig. 3). In the preferred embodiment shown, the minimum extent of the first longitudinal edge 23 being folded toward the width of the second adhesive 27 is, for example, 2 millimeters (mm). However, the leading edge 23 can also be folded over a greater or greater extent of the width of the second adhesive zone 27 as long as the first longitudinal edge 23 can be securely adhered to the second adhesive. In the next step, as shown in Fig. 2, the second longitudinal edge is folded along the central axis 38 of the blank region 36 such that the third adhesive region 28 is a portion 34 of the back surface 24 of the substrate 20. Thus, the second through hole 42 is formed (indicated by the broken line 44) and the louver 50 according to the first example of the present invention is completed. Fig. 5 shows a louver 5 依据 according to a second embodiment of the present invention, in which only a long through hole 52 (in a broken line) is formed in the louver 50. In this embodiment, the louver 50 is formed by forming a first surface adhesion 30 by using the first adhesion shown in FIG. 3 (the second contact strip with a vertical area and a small vertical area). No substrate -7-(5) 1276733 20 is formed. As shown in Fig. 6, the first longitudinal edge 2 3 of the front surface 22 is folded forward. The second longitudinal edge 25 of the face 22 makes the first The blank area 3 〇 and the second blank area 3 6 (shown in Fig. 3) coincide with each other. This causes the first longitudinal edge 2 j of the front surface to contact the viscous area 2 8 and form the back surface 2 4 as it is. a portion 34, as shown in Fig. 5, in the next step, the second longitudinal edge 25 is folded upwards so that the second brother's adhesive area 28 contacts the portion of the back side 2 4 3 4 ', thus, A through hole 52 is formed.
