ADSORBING DISPOSABLE DIAPER Russian patent published in 2013 - IPC A61F13/15 

FIELD: medicine.

SUBSTANCE: invention relates to method of manufacturing adsorbing disposable diapers (2) of open type with main part (4), which contains frontal area (6) with frontal lateral longitudinal edges (42), back area (8) with back lateral longitudinal edges (41) and located between them in longitudinal direction (28), intended for application between user's legs perineal area (10). Main part (4) contains adsorbing body (12) and with connected from two sides with back area (8) back lateral sections (20) and with connected from two sides with frontal area (6) frontal lateral sections (22), which pass in transverse direction (30) outwards beyond lateral frontal and back longitudinal edges (42, 41) of main part (4) and in applied state of adsorbing disposable diaper (2) connect frontal area (6) and back area (8) with each other. To form regions of cuts for legs lateral sections (20, 22) on, at least, facing perineal area (10) edges are made passing in oblique way to longitudinal direction (28) or curvilinear, and main part (4), at least, in perineal area is made in form of sand clock, and method includes the following stages: supply of endless flat cloth (50, 50a) of material in longitudinal direction (28) for manufacturing segments (66, 66a) of material for formation of lateral sections (20, 22), making first extractions (52) of material along first line (100) of cutting on lateral edge (70, 70a, 70b) of flat cloth (50, 50a) of material to form contour cuts in flat cloth (50, 50a) of material, with imaginary parallel PL to longitudinal direction, which in point P reaches maximal length of cut-out transversely to longitudinal direction (28) determining external partial area (80) and internal partial area (81) of flat cloth (50) of material. Folding flat cloth (50, 50a) of material, at least, on passing in longitudinal direction (28) first line (36) of bend, and line (36) of bend passes inside external partial area (80), separation of longitudinal segments of folded flat cloth (50, 50a) of material for corresponding formation of segments (66, 66a) of material, non-detachable fixation of segments (66, 66a) of material on corresponding longitudinal edge (91) of cloth (90) of main parts of diapers for formation of lateral sections (20, 22), making second extractions (53) of material along second line (101) of cutting, second line (101) of cutting includes lateral sections (20, 22) and corresponding longitudinal edge (91) of cloth (90) of main parts of diapers, with second line (101) of cutting crossing first line (100) of cutting in such a way that second line (101) of cutting does not pass through first line (36) of bend of frontal and back sections (20, 22).

EFFECT: due to the invention method possibility of stable direction and processing of not finished cloth of diapers with already attached lateral sections in high-speed machines for diaper production is achieved.
