• at least one of the front body panel and the rear body panel is a combined panel, and the combined panel comprises a pair of leg elastic members arranged adjacent the pair of leg edges of the combined panel, wherein each leg elastic member extends at least partially in a direction other than parallel with the transversal direction,
• wherein the combined panel comprises, as seen along the longitudinal direction, a first panel portion and a second panel portion, the first panel portion and the second panel portion being connected by a connection region,
• wherein the first panel portion extends from the connection region in the longitudinal direction towards the waist edge of the combined panel, and the second panel portion extends from the connection region in the longitudinal direction towards the pair of leg edges, the second panel portion comprising the pair of leg elastic members,
• wherein the first panel portion comprises a first bottom layer and a first top layer being superimposed such that, in the first panel portion, the first bottom layer forms a bottom side surface of the combined panel and the first top layer forms a top side surface of the combined panel, the first panel portion further comprises a first set of elastomeric strands being sandwiched between the first bottom layer and the first top layer, the elastomeric strands being aligned substantially in parallel with each other and with the transversal direction, and being spaced apart from each other in the longitudinal direction, and
• the first panel portion is bonded by the first bottom layer being bonded to the first top layer by a welded bond pattern, attaching the first set of elastomeric strands between the first bottom layer and the first top layer, and
• the second panel portion comprises a second bottom layer and a second top layer being superimposed such that, in the second panel portion, the second bottom layer forms a bottom side surface and the second top layer forms a top side surface of the combined panel, wherein the pair of leg elastic members are sandwiched between the second bottom layer and the second top layer, and
• the second panel portion is bonded by the second bottom layer being bonded to the second top layer by adhesive bonds, attaching the pair of leg elastic members between the second bottom layer and the second top layer.

A method for forming a combined laminate material web for a disposable hygienic article, the combined laminate material web being continuous as seen in a machine direction and having a width in a cross-direction perpendicular to the machine direction, between a first side edge and a second side edge, the combined laminate material web defining a top side and a bottom side as seen in a thickness direction being perpendicular to the machine direction and to the cross-direction, the method comprising

• a welding bonding step comprising
• feeding a first bottom layer web, a first top layer web, and a first set of continuous elastic strands in the machine direction, and
• bonding the first bottom layer web to the first top layer web by a welded bond pattern so as to attach the first set of continuous elastic strands between the first bottom layer web and the first top layer web, the first set of elastomeric strands being aligned substantially in parallel with each other and with the machine direction, and being spaced apart from each other in the cross-direction;
• and
• an adhesive bonding step comprising:
• feeding a second bottom layer web, and a second top layer web in the machine direction, and feeding a set of one or more continuous additional elastic members to be sandwiched between said second bottom layer web and second top layer web, and
• bonding the second bottom layer web to the second top layer web by adhesive bonds so as to attach the set of one or more continuous additional elastic members, between the second bottom layer web and the second top layer web,
• the additional elastic members extending at least partially in a direction not parallel with the machine direction, so as to form
• a first web portion, wherein the first bottom layer web forms a bottom side surface and the first top layer web forms a top side surface of the combined laminate material web, and
• a second web portion, wherein the second bottom layer web forms a bottom side surface and the second top layer web forms a top side surface of the combined laminate material web,
• the second web portion being connected to the first web portion via a connection region extending along the machine direction.
