Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for painting blind blades, and in particular, when the blades are set as a blind, the blind filter pattern composed of each pattern applied to the blind blade does not look unnatural. Concerning how to paint blind feathers.

Traditionally, blind blades have been lined up so that they do not overlap each other, and painted using methods such as silk screen printing. A desired pattern is formed on the printing plate used for printing, but when blind blades are set as a blind, adjacent blind blades always overlap by a certain number of millimeters, so this overlap is smaller than the desired pattern. The problem was that the pattern was shortened by the length of the overlapped part (double part), and the pattern overlapped, resulting in a discontinuous pattern, resulting in an unnatural pattern. Therefore,
Conventionally, in order to solve this problem, blind blades are set in advance as a blind and then printed using an inkjet method or a silk screen method, or a film with a pattern is printed on a single blind blade. Methods such as aligning the sheets one by one and pasting them together are used.

However, the former two methods have the drawback that it is difficult to express a photographic pattern, and only a monotonous or monochromatic pattern can be produced, while the latter bonding method has the drawback of lacking workability.

The present invention provides a method that overcomes all of the drawbacks of such conventional methods. That is, the present invention provides a method for painting blind blades made by coating an aluminum material with synthetic resin paint, in which the width of the blade is h, and the width of each blade is the same as the upper blade when set as a blind. , if the double width of the lower blade is W, then from the top edge of the blind
1.3.5.7.……Arrange the feathers placed at odd-numbered positions of 2n-1 with an interval P shown as P = 2h-2W, and transfer the painting using transfer paper containing sublimable dye. , while the blades placed at the even numbered positions of 2.4.6.8....2n from the upper end of the blind are placed below the arrangement position of the blades placed at the odd numbered positions by a distance L shown by L=h-W. The blades may be arranged at intervals P and transferred using another sheet of transfer paper that is the same as the transfer paper, or the feathers that would be placed at even-numbered positions may be placed at the odd-numbered positions. Arrange the blades at the same position as the blades to be removed, and move another sheet of transfer paper identical to the above transfer paper upward by a distance L.
This method of painting blind feathers is characterized by transferring the painting by shifting it by a certain amount.

Note that by preheating the blind blades in advance, the transfer efficiency during transfer decoration can be increased.

This will be explained in detail below using the drawings. That is, as shown in Fig. 1, aluminum blind blades 2 coated with acrylic baking paint and having a width h = 25 m/m are placed on a transfer table 1 at a pitch P = 43 m/m.
Set at intervals of In addition, P is the value obtained from P=2h−2W=2×25−2×3.5=43, assuming the blade double width W=3.5m/m, and this blade 2 is from the odd numbered group. .

Next, a transfer paper 3 on which a blind pattern has been appropriately formed with ink containing a sublimable dye is set on the blind blades 2, and a heating plate 4 heated to about 190° C. is brought close to the transfer paper 3. Preheat for about 20 seconds. Note that this preheating is performed on the blind blade 2.
This is to thermally expand the material and improve the subsequent transfer efficiency. Next, as shown in FIG. 2, the heating plate 4 is heated and pressed from above the transfer paper 3 to perform thermal transfer for 30 seconds. On the other hand, as shown in Fig. 3, the blind blades 5 of the even-numbered groups are shifted downward by 21.5 m/m, which is expressed by L = h - W = 25 - 3.5 = 21.5, so that the interval P = 43 m/m. Transfer paper 6 with the same pattern as the transfer paper on which the blind blades 2 of the odd-numbered group were transferred is set in the same position as the set position where the blind blades 2 of the odd-numbered group were painted, and transfer is performed in the same manner. Let's do it.

In addition, when the setting position of the blind blades 5 of the even-numbered group is set at the same place as the setting position of the blind blades 2 of the odd-numbered group, the setting position of the transfer paper 6 is shifted upward by 21.5 m/m and set. do.

Blind feathers painted in this way 2,
The painted state of No. 5 is shown in FIGS. 4 and 5. FIG. 6 shows a blind pattern formed by each of the blind blades 2 and 5 when the blind blades 2 and 5 are set as a blind.

Here, as the synthetic resin to be coated on the aluminum material, most synthetic resins can be used, but polyester resins, amino resins, aminoalkyd resins, vinyl chloride resins, vinyl acetate resins, acrylic resins, urethane resins, etc. are particularly preferred.

Further, the transfer paper containing a sublimable dye refers to the well-known sublimation transfer paper disclosed in Japanese Patent Publication No. 39-18793, Japanese Patent Publication No. 38-15013, and the like.

Since the present invention has the above-mentioned content, compared to the conventional method of painting blind blades, when the blades are set as a blind, the pattern of the blind consisting of each pattern applied to the blind blades is The practical effects of the present invention are great, such as the fact that the pattern does not look unnatural, the workability is good, and photographic patterns can be easily created.

Claims (1)

[Claims] 1. In a method of painting blind wings made by coating an aluminum material with synthetic resin paint, the width of the wings is h, and the width of each wing when set as a blind is If the double width of the blade and the blade below it is W, then the blade placed at the odd numbered position of 1.3.5.7....2n-1 from the top edge of the blind is expressed as P = 2h-2W. The blades are arranged at the even numbered positions of 2.4.6.8....2n from the upper edge of the blind, and the blades are placed at the odd numbered positions from the top of the blind. Shift the feathers downward by a distance L shown by L = h - W from the arrangement position of the feathers, arrange them at an interval P, and use another sheet of transfer paper that is the same as the above transfer paper to transfer the painting. Alternatively, the blades placed in even-numbered positions are arranged in the same position as the blades placed in odd-numbered positions, and another sheet of transfer paper that is the same as the transfer paper is moved upward a distance L.
