Abstract

Tête d'impression (10) à matrice de fils (46) permettant l'impression de points de petit diamètre se chevauchant pour une meilleure définition des caractères imprimés. La tête (10) comporte des fils (46) dont une partie est commandée par un premier groupe d'électro-­ aimants (18) montés en cercle et régulièrement espacés sur une première plaque de montage (14) et dont l'autre partie est commandée par un second groupe d'électro-­ aimants (19) montés en cercle et régulièrement espacés sur une seconde plaque de montage (16). Les électro-aimants (19) du second groupe sont décalés angulairement par rap­ port à ceux (18) du premier groupe. Les deux groupes de fils (46) qui, au voisinage des électro-aimants (18, 19) sont dis­ posés en cercle, traversent des guides (56, 71, 74) qui les disposent selon les lignes et colonnes d'une matrice. Une partie (56) des guides est formée par un élément creux (60) rempli de matériau thermodurcissable (59) dans lequel des passages (58) ont été formés par des fils-gabarits retirés après durcissement du matériau (59).
