Abstract RU 2694920 C2

FIELD: hygiene.

SUBSTANCE: problem is solved by means of stretching structure (20X) of absorbent product, including stretching section (80) and non-stretching section (70), extending from stretchable section (80), where the laminate consisting of the first sheet layer (20A), the second sheet layer (20B) and elastic film (30) between the first sheet layer (20A) and the second sheet layer (20B), extends over stretchable portion (80) and non-stretching section (70), first sheet layer (20A) and second sheet layer (20B) are connected to each other by a large number of point connections (40) through via holes (31) formed in elastic film (30) stretched along surfaces of first sheet layer (20A) and second sheet layer (20B) in tension direction, point connections (40) are arranged with intervals in direction of stretching and direction, perpendicular to stretching direction, end of stretching section (80) adjacent to non-stretching section (70) is intermediate stretching part (82), and the area of point joints (40) in the intermediate stretch portion (82) is greater than the portion of the area of point joints (40) in main portion (81) not including the intermediate stretchable portion (82).

EFFECT: task is to prevent rupture of elastic film along boundary between stretchable section and non-stretching section.
