A composite sheet which has a low basis weight and in which adhesive oozing can be inhibited. The composite sheet (1) is a sheet formed by bonding a stretch nonwoven fabric (2) to a nonstretch nonwoven fabric (3) with an adhesive (4). The stretch nonwoven fabric (2) is bonded in a stretched state to the nonstretch sheet. The stretch nonwoven fabric (2) has, on each side, sparse regions (21) and dense regions (22) alternately formed. The sparse regions (21) and dense regions (22) on one side are alternately formed in a second direction so that the dense regions (22) on this side do not overlie the dense regions (22) on the other side. The stretch nonwoven fabric (2) comprises thermoplastic fibers which have been stretched at least partly and elastomer fibers.

L'invention concerne une feuille composite de faible masse surfacique et dans laquelle le suitement d'un adhésif peut être inhibé. Ladite feuille composite (1) est formée par liaison d'un tissu nontissé extensible (2) à un tissu nontissé non extensible (3) au moyen d'un adhésif (4). Le tissu nontissé extensible (2) est lié de façon non extensible à la feuille non extensible. Le tissu nontissé extensible (2) comprend, sur chaque côté, une alternance de régions de faible densité (21) et de régions denses (22). Les régions de faible densité (21) et les régions denses (22) sur un côté sont formées par alternance dans un deuxième sens de façon que les régions denses (22) sur ce même côté ne recouvrent pas les régions denses (22) sur l'autre côté. Le tissu nontissé extensible (2) comprend des fibres thermoplastiques qui ont été étirées au moins partiellement et des fibres élastomères.
