摘要：
An absorbent structure (70) comprising a substantially planar substrate (16), an auxiliary glue (72) applied directly over the substrate (16) on an auxiliary glue application area (71), an absorbent material comprising from 80% to 100% by weight of superabsorbent particles deposited on the substrate on an absorbent material deposition area (73) comprising a pattern of absorbent material land areas (75) separated by absorbent material-free junction areas (76), wherein the absorbent material deposition area can be notionally divided in eight deposition zones (Z1-Z8) of equal length along the longitudinal direction. A fibrous thermoplastic adhesive layer (74) covers at least some of the land areas and at least some of the absorbent material-free junction areas to thereby immobilize at least some of the absorbent material on the substrate. The absorbent material is profiled along the longitudinal direction of the structure so that at least one of the eight deposition zones is a zone of lower absorbent material amount (Z1, Z2, Z7, Z8) and the auxiliary glue (71) is absent, or present at a level of at least 50% by weight lower than the average amount of auxiliary glue in at least one of these zones (Z1, Z2, Z7, Z8) of lower absorbent material amount. The absorbent structure can be made in an absorbent core for absorbent articles such as diapers.Una estructura absorbente (70) que comprende un sustrato sustancialmente plano (16), un pegamento auxiliar (72) aplicado directamente sobre el sustrato (16) en el área de aplicación de pegamento auxiliar (71), un material absorbente que comprende de 80 % a 100 % en peso de partículas superabsorbentes depositadas en el sustrato en un área de depósito de material absorbente (73), que comprende un patrón áreas de depósito de material absorbente (75) separadas por áreas de unión libres de material absorbente (76), en donde el área de depósito de material absorbente puede, teóricamente, dividirse en ocho zonas de depósito (Z1-Z8) de igu
