Description

[Detailed Description of the Invention] To obtain a honeycomb-like structure that can be used for a single period in a heat exchanger, dehumidifier, gas adsorption device, filter, etc., a single-wave molded body is made from two sheet materials such as paper or cloth. The most convenient method is to obtain a sheet material and laminate it, and packaging corrugated cardboard is also manufactured using the same process, but when the sheet material is passed between forming gears and formed into a wave shape, If the sheet material is torn due to being pressed in direct contact with the forming gear and being strongly pulled in the direction of its propagation, the performance of the resulting honeycomb-like structure will deteriorate or it will become completely unusable, and the sheet material will become very fragile. If the structure is coarse and the physical waveform is weak, such as carbon fiber paper, glass fiber paper, R paper, heat-softening synthetic side fat sheet, etc., the base side of the sheet is particularly easy to tear; However, it has the disadvantage that it tends to wrinkle, requires special skill and care in forming and laminating, and does not improve work efficiency.

The present invention eliminates the above-mentioned disadvantages, and provides a protective film between the sheet material and the forming roller, such as a film or a strong adhesive film, such as a polyester or other synthetic resin film, which is not tacky to the sheet material, the forming roller, or the pressure roller. By sandwiching a piece of paper or the like and bringing out the meshing part of the forming gear together with the sheet material, it is possible to reliably and easily produce a single wave molded object without fear of tearing the sheet material during molding, even if the sheet material is weak. .

The embodiment will be described below with reference to the drawings. As shown in FIG.
The forming gears (5) are connected to each other so that their teeth mesh with each other, and a pressure roller (6) is pressed against one of the forming gears (5), and the forming gears (5) are rotated at the same circumferential speed. (9) is an adhesive seed container, and the adhesive agent (11) is placed so that the transfer roller (lO) is partially immersed, and the adhesive roller (12) is placed in contact with the transfer roller (10) and forming gear (5). Place. The transfer roller (10) and the adhesive applicator roller (12) are driven to rotate at least one or both of them, and the adhesive applicator roller (12) is rotated by the forming roller (12).
5) means that tγ rotates at the same circumferential speed.

The protective film is a film that does not adhere to 7) (la) and the molded gear (5) and does not plastically deform into a υ wave shape when the molded gears (4) and (5) meet, for example, a saturated polyester, Select from synthetic resin films such as polyethylene, polypropylene, or kraft paper.

), the adhesive (11) is applied, and then the adhesive film (7) and the flat-concave sheet material (2) are guided between the forming gear (5) and the pressure roller (6), and the corrugated sheet material U) is applied. and the planar sheet material (2) are glued together to form a piece V,
A molded body (3) is obtained. The single-wave molded rhinoceros β) and protection film ()) are once washed as shown in the figure, the single-wave molded body (3) is used in the next process, and the protective films ('7) and (8) are repeatedly semi-permanently treated. It can be used in many ways. In addition, (131, (131・

An example of the obtained single-wave molded product is shown in FIG. 3, but the cross-sectional shape of the waves of the corrugated sheet (1) is of course not limited to the sine wave shape shown in the figure, but may also be a shape of connected semicircles, a round shape, A variety of waveforms are used, such as a shape that connects two sides of a triangle.

The single-wave molded body thus obtained is divided into four layered bales to form a honeycomb-shaped fI body, for example, a rotary type body as shown in FIG.
It is possible to obtain the Kaifu-style heat exchange element shown in Figure 5, and a confectionery for dehumidifiers, as well as sheets.

When one end and the other end of the small through holes of the laminate are alternately closed, a filter element is obtained.

In the above embodiment, when forming the sheet material (la 1), protective films (-') and (8) are applied to both sides of the sheet material (la 1). may be used.

As described above, when forming the corrugated sheet material (1), the present invention directly contacts the forming roller, and on the contact surface, the sheet material directly contacts the forming gear and is pressed, and receives tensile stress in the advancing direction and slides. ,! ≠ Eliminates the risk of tearing due to rubbing, and the sheet material is Japanese paper, metal, -4
K is also special, so it can be formed and laminated without any special care, such as when it is very thin like a board, or when it has a coarse structure like P paper or activated carbon fiber paper, and it is more effective than when a protective film is not used. This has the effect of significantly increasing work efficiency and reducing the amount of defects.
