Abstract
Dispositif d'entretoisement d'éléments disposés en un réseau triangulaire régulier, ce dispositif se composant de feuillards replies plusieurs fois, reliés en un treillis, formant entre eux des espaces hexagonaux et comportant des parties recourbées formant des appuis pour les éléments. Le treillis est formé de manière que les côtés des hexagones par lesquels deux feuillards sont en contact sont plus courts que les autres côtés libres et chacun de ceux-ci comporte deux languettes élastiques juxtaposées de manière que chacune fasse saillie dans l'un des espaces hexagonaux voisins. Application à l'entretoisement de tubes d'échange de chaleur.
