Absorbent sanitary article and a method for producing the same

A method for producing absorbent sanitary articles, comprising:

• providing a continuous elastic laminate elongated in a longitudinal direction and comprising two continuous non-elastic outer layers and a plurality of elastic elements sandwiched between the two non-elastic outer layers, wherein said plurality of elastic elements are elastically stretchable in a transverse direction and are spaced apart from each other in the longitudinal direction, and wherein the plurality of elastic elements in the transverse direction are shorter than the non-elastic outer layers,
• providing an array of chassis each having a longitudinal axis, two side edges, rear and front waist sections, and a crotch section intermediate between the rear and front waist sections, each chassis including a topsheet having an outer surface which in use is adapted to be in contact with a user's skin, a backsheet, and an absorbent core set between the topsheet and the backsheet,
• transversely cutting said continuous elastic laminate to form individual gasketing elements each including two non-elastic outer layers and a transversally stretchable elastic film sandwiched between said two non-elastic outer layers, wherein the two outer layers are separate and distinct layers fixed to each other to sandwich the transversally stretchable elastic film therebetween, wherein the transversally stretchable elastic film is shorter than the two non-elastic outer layers both in the direction of said longitudinal axis and in a transverse direction orthogonal to the longitudinal axis, so that each individual gasketing element has two non-elastic longitudinal portions and two non-elastic transverse portions forming a non-elastic frame surrounding the transversally stretchable elastic film,
• applying said individual gasketing elements on the outer surface of the topsheet of a respective chassis in at least one of said rear and front waist sections, and
• attaching said individual gasketing elements to respective chassis along a C-shaped attachment profile including two opposite longitudinal portions and a transverse outer portion, wherein a central inner region of the individual gasketing element is detached from the outer surface of the topsheet to form a pocket open toward said crotch section,
• wherein the central region includes the transversally stretchable elastic film such that the transversally stretchable elastic film is detached from the outer surface of the topsheet and is surrounded on three sides by the C-shaped attachment profile, and
• wherein said individual gasketing elements are formed with a width in the transverse direction which is less than the width in the transverse direction of the respective rear or front waist section of the chassis.
