Description

one

The known methods of making honeycomb material by gluing, for example, paper tapes with preliminary application of adhesive strips to the tape and the subsequent operations of forming a package, have little productivity and do not allow to automate the process.

The purpose of the invention is to increase labor productivity and automate the process of manufacturing cellular material.

For this, according to the proposed method, adhesive strips are applied from the middle of the tape to half of its width, bend it along the clean edges in the direction of the applied adhesive strips to the middle, then after polymerization, strips corresponding to the height of the honeycomb are cut off from the tape, folded into a block the mixed adhesive strips are glued together, then they are faced and stretched into a honeycomb with subsequent impregnation and filling of the aggregate into cells.

The proposed method is illustrated in the drawing.

Glue strips 3 (section A-A) are rolled out from a roll 1 on a half of the width of a tape 2 from its middle, then the tape 2 is bent with a guide roller towards the midpoint in the direction of glue strips (sections A-A, B- B, C-C) and is fed to the polymerization chamber 4, where the adhesive cures. Then the glued tape is cut by the mechanism 5, cutting off the strip of the required: size. The cut strip is again applied; adhesive strips, shifted by half a step relation;

glue strips previously applied; and then the strips are placed in the bag 6. The bag is pushed into the polymerization chamber, the latter is then end-faceted with its bottom surface; Nism 7. Then the package is stretched in;

honeycomb and served in the impregnation chamber, where the honeycomb cell is poured resin through the slit in: the pipe 8. The utility cell enters the; a polymerization chamber 9 where si- is blown; Charger compressed hot air. Cured;

honeycomb enters the blowing device W from which up comes; foaming material, for example, a Mipora, which fills the cells of the cell all the way, which means that the finished continuous cell goes to; the cutting mechanism 11, where sotoblocks 12 are cut from it of the required length and transported to the place of installation.

In order to increase labor productivity and automate the process, adhesive strips are applied from the middle of the tape at half its width, bend it along the clean edges towards the applied adhesive strips to the middle, then after polymerization they cut off

from the tape, strips along the length corresponding to the height of the honeycomb block are folded into a block with preliminary deposition of displaced adhesive strips onto the strips and glued together, then they are pressed and stretched into a honeycomb block with subsequent impregnation and cell filling operations.
