摘要： An absorbent article has a front side, a back side, a longitudinal axis, a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core between the topsheet and the backsheet. The absorbent core includes a first type of channels, wherein the top side and the bottom side of the core wrap are bonded to another, and a second type of channels, wherein the top side and the bottom side of the core wrap are not bonded or are less bonded to one another in this second type of channels than in the first type of channels. The absorbent material may also include cellulose and superabsorbent particles.

摘要： An apparatus for forming an absorbent pad for an absorbent sanitary article having a zone free of absorbent material to define a channel of the pad includes a forming drum, a first feed system for feeding a first web, a second feed system for feeding a second web, a spreader for spreading the absorbent material on the drum; a joining system for joining the first and second webs to define the channels. A first dispenser forms on the first web a layer of first adhesive substance according to a spreading pattern having zones free of the first adhesive substance corresponding to the channels. A second dispenser dispenses a second adhesive substance, whose adhesive force is greater than an adhesive force of the first adhesive substance, on the second web according to a pattern having a layer placed at a zone free of the first adhesive substance.

摘要： Provided is a method for producing a granular powder-containing sheet containing a granular powder in separated container rooms between two sheet materials. After the container rooms are formed in a first sheet material, the first sheet material is transported on the circumferential surface of an anvil roller. In the process of transportation, the granular powder that is fed from a granular powder feeding hopper through a feeding passage is received in the container rooms. Thereafter, the container rooms are covered with a second sheet material, and the two sheet materials are joined to each other on the peripheries of the container rooms.
