Absorbent article and method for manufacturing an absorbent article

An absorbent article comprising an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet, said article being arranged along a longitudinal axis and a transversal axis extending in a perpendicular direction in relation to the longitudinal axis and said article defining a front portion, a back portion and a crotch portion,

• wherein said absorbent core comprises
• an absorbent component enclosed by a core cover comprising an upper side and a lower side, and
• a sealing arrangement for joining said upper and lower sides and comprising two channel sealings, a first channel sealing in a first channel and a second channel sealing in a second channel, in said crotch portion, the first channel sealing defining a first channel sealing width and the second channel sealing defining a second channel sealing width,
• wherein the channel sealings are each formed by a thermo and/or mechanical welding pattern comprising a plurality of welding spots being arranged in the form of a first row along the longitudinal axis in which each welding spot extends along a first axis, and a second row along the longitudinal axis in which each welding spot extends along a second axis, said first axis and second axis defining a first angle in relation to each other, such that the first axis is not parallel to the second axis,
• wherein the sealing arrangement further comprises two side seams along sides of said core,
• wherein the channel sealings define a first effective channel sealing width and a second effective channel sealing width, respectively, and wherein the side seams define a third and fourth effective width, respectively, along said crotch portion and define a fifth and sixth effective width, respectively, along said front portion and back portion;
• said effective widths being defined as an extension of said sealing arrangement in a transverse direction of the article, along any cross-section of the crotch portion,
• wherein the sum of said first to sixth effective widths in the transversal direction is generally constant along said core.
