As shown in the figure, conventional plastic honeycomb cores have been mainly manufactured by hot pressing. That is, by using upper and lower press molds 1 and 2 that are approximately plate-shaped and in which corrugated irregularities are continuously formed, a predetermined length of plastic material A is sandwiched between the press surfaces of such press molds 1 and 2, and A corrugated sheet B having corrugated irregularities is formed by heating and pressurizing, and the corrugated sheet B is formed into a corrugated sheet B, which is then released from the press molds 1 and 2. Such operations were repeated for each plastic material A to form corrugated sheets B one by one, and then these were stacked and bonded together to produce a honeycomb core.

First of all, there was a cost problem due to poor productivity. That is, press dies 1 and 2 are used to produce corrugated plates B one by one.
The honeycomb core manufacturing process is divided and cannot be carried out continuously, resulting in poor production efficiency and high costs. Second, there was a problem in that the longitudinal dimension of the honeycomb core was limited. In other words, since the length of the corrugated sheet B in the longitudinal direction is limited by the size of the press molds 1 and 2, and it is not possible to make a longer length, the longitudinal dimension of the manufactured honeycomb core is also limited. Ta. Third
Another problem was the shape of the honeycomb core. That is,
The corrugated sheet B is formed by pressing the plastic material A between the pressing surfaces of press molds 1 and 2 at once, and at that time, pressure is applied all over from the top and bottom at once, so there is little room for the pressure to escape, etc. The irregularities of the molded corrugated sheet B do not follow the irregularities of the press molds 1 and 2 accurately, and the shape tends to be inaccurate and uneven, and the honeycomb core manufactured thereby also has poor cell shape accuracy. This often resulted in poor quality problems.

が向上する。[Function] The method for manufacturing a plastic honeycomb core according to claims 1 and 2 of the present invention comprises the above-mentioned means, and therefore functions as follows. That is, a corrugated sheet is formed by heating and pressing a band-shaped plastic material while passing it between predetermined corrugate rollers, or by heating and then passing it between predetermined corrugate belts and pressurizing it between driving rollers. A plastic honeycomb core is manufactured by applying an adhesive to the corrugated sheets, cutting them, and stacking them together. First, the corrugated sheet is continuously molded, each process is not separated, and the plastic honeycomb core is manufactured continuously. Second, a band-shaped corrugated sheet is formed by pressing the band-shaped plastic material between rotationally driven corrugated rollers or driving rollers of a corrugated belt. Therefore, the length of the corrugated plate in the longitudinal direction is not limited, nor is the dimension of the manufactured plastic honeycomb core in the longitudinal direction. Thirdly, since the corrugated sheet is similarly formed, the pressure is concentrated on the plastic material at one point and not all over the plastic material at once. Therefore, a corrugated plate with accurate and uniform unevenness is formed, and the precision of the cell shape of the manufactured plastic honeycomb core is improved.
