Abstract

L'invention concerne une installation (10) de traitement d'éléments plats (12 ; 14), en particulier, en verre ou en bois, matière plastique, aluminium ou analogues. L'installation (10) comprend un dispositif d'avance (16) destiné à l'acheminement des éléments plats à traiter (12 ; 14) et un dispositif à pont, fixé à demeure (30), agencé transversalement au dispositif d'avance (16). Il est prévu, sur le dispositif à pont (30) une paire de supports réglables (32) sur chacun desquels est monté pivotant au moins une broche de traitement ou un système tournant (36) équipé d'une pluralité d'outils de perçage. Pour la réalisation d'une telle installation (10) il est prévu, avec un faible encombrement pour l'emplacement et la surface de base, et avec peu de frais d'investissement, sur l'un des supports (32) du dispositif à pont (30), en plus des outils de perçage (40), également un outil de meulage (42), ce dernier étant, de préférence, combiné avec un outil de polissage (44).
