Apparatus for manufacturing an absorbent article with channels

An apparatus for manufacturing an absorbent article, said apparatus comprising:

• a. a rotating member for guiding a first sheet material along a surface thereof, wherein the surface of said rotating member is provided with at least one suction zone and at least one non-suction zone;
• b. an application unit configured for applying an absorbent material on said first sheet material on the rotating member;
• c. an air jet system configured for locally removing the absorbent material applied on at least one attachment portion of the first sheet material located above the at least one non-suction zone, such that at least one remaining portion of the first sheet material located above the at least one suction zone is covered with absorbent material and substantially no absorbent material is present on the at least one attachment portion;
• d. a sheet feed unit configured for applying a second sheet material on top of the absorbent material on the first sheet material;
• wherein one of said first and second sheet material is a top core wrap sheet material, and the other one is a back core wrap sheet material;
• e. an attachment unit configured for attaching said first sheet material to said second sheet material at least in the at least one attachment portion.
