Dispositif applicateur pour machine de nappage à tête mobile (2), destinée à napper une surface d'application (3) au moyen d'un ruban (4) de matière composite, ledit dispositif comportant un rouleau rotatif d'application (6) porté par une monture (5) solidaire de ladite tête mobile qui applique ledit rouleau contre ladite surface d'application et qui avance ledit rouleau transversalement à son axe de rotation pour que celui-ci applique en roulant ledit ruban sur ladite surface d'application. Selon l'invention, ce dispositif est caractérisé en ce que : - ledit rouleau rotatif d'application (6) comporte un arbre souple (6A) élastiquement déformable en flexion et un cylindre (6B) de matière élastiquement compressible solidaire dudit arbre ; - chaque extrémité dudit arbre est reliée à ladite monture (5) par un palier d'extrémité (7.1, 7.2) ; et - au moins un palier intermédiaire (10) est prévu entre lesdits paliers d'extrémité (7.1, 7.2) pour relier ledit arbre (6) à ladite monture (5). Applicator device for a laying machine with mobile head, for laying a composite material tape on a surface of application, said device comprising a rotary application roller carried by a mount fixed to said mobile head which applies said roller against said application surface and which advances said roller transversely to its axis of rotation so that while rolling it applies said tape on said application surface. According to the invention, this device is characterized in that said rotary application roller comprises a resiliently flexible shaft deformable under flexion and a cylinder of resiliently compressible material fast with said shaft, each end of said shaft is connected to said mount by an end bearing, and at least one intermediate bearing is provided between said end bearings for connecting said shaft to said mount.
