METHOD FOR MANUFACTURE ABSORPTION HOLDER CARTRIDGE Russian patent published in 2018 - IPC A62B19/00 

FIELD: human vital needs satisfaction.

SUBSTANCE: absorber sheets are rolled and a separating grid is placed between the absorber coils, wherein the absorber sheets are made in the form of a shell of a gas permeable material into which partially dewatered pasty absorbent material is placed. The difference of the method is that the shell is sealed by welding in the form of a sleeve with a seam on the outer side surface, after which the sleeve is turned inside out forming an internal seam which is unfolded into the middle part of the side surface. The sleeve receives a folded shape and the absorbent material is fed through the central portion, subsequently unfolding the sleeve into a strip and filling its free portion with absorbent material, the filled strip is profiled and subjected to IR drying to a predetermined humidity, and rolled together with the separation grid on the central tube. Before folding into a roll, the lateral surfaces of the separation grid are cut at a width of 2-3 mm at a distance from the end equal to the two outer turns of the spiral.

EFFECT: increased efficiency of the absorption cartridge by increasing the amount of absorber working out.
