A method for manufacturing absorbent cores for absorbent sanitary articles, comprising: providing a rotating forming wheel including a plurality of forming elements defining a peripheral surface of the forming wheel, each of the forming elements comprising at least one protruding rib inserted into a respective groove formed on a suction surface of the respective forming element, providing a forming chamber containing absorbent material facing a portion of the forming wheel; feeding a first nonwoven web onto the peripheral surface of the forming wheel upstream of the forming chamber; retaining absorbent material on said first nonwoven web at the suction surfaces of the forming elements connected to a suction source; blowing air through blowing surfaces of the protruding ribs, the blowing surfaces being spaced apart radially from respective suction surfaces; feeding a second nonwoven web onto the forming wheel over the absorbent material; and fastening together the first and second nonwoven webs along channels without absorbent material formed by the blowing surfaces.
An apparatus for manufacturing absorbent cores for absorbent sanitary articles, comprising: a rotating forming wheel including a plurality of forming elements defining a peripheral surface of the forming wheel; a forming chamber containing absorbent material facing a portion of the peripheral surface of the forming wheel; a first roller for feeding a first nonwoven web onto the peripheral surface of the forming wheel upstream of the forming chamber; and a second roller for feeding a second nonwoven web onto the peripheral surface of the forming wheel downstream of the forming chamber, wherein each of the forming elements comprises a suction surface connected to a suction source, and at least one protruding rib having a blowing surface selectively connected to a stationary blowing device, wherein: the at least one blowing surface and the suction surface are spaced apart from each other in a radial direction, and the protruding rib is inserted into a respective groove formed on the suction surface of the respective forming element.
