PCT No. PCT/US95/07252 Sec. 371 Date Dec. 20, 1996 Sec. 102(e) Date Dec. 20, 1996 PCT Filed Jun. 7, 1995 PCT Pub. No. WO96/00547 PCT Pub. Date Jan. 11, 1996A process to make a profiled disposable absorbent product is disclosed. The disposable absorbent product has a first sheet, a second sheet and a fibrous core. The core is disposed between the first and second sheets and both sheets are joined to each other along a continuous or discontinuous line. The process comprises the steps of joining the first sheet to the second sheet along a line following at least part of the periphery of the core with a distance to the core of 3 mm to 8 mm; and calendering the core between the sheets in a calender to approximately uniform density, the calendering being such that the core expands along its periphery and thereby reduces the distance of between the edge of the core and the line joining the first sheet to the second sheet by 1 mm or more. The process provides absorbent articles with very small distances between the core and the line of joining the topsheet and backsheet of the absorbent article.
