An improved method of affixing spheres (4) to a foil matrix (2) is described herein. First, a cell sandwich (32) is prepared. This cell sandwich (32) includes spheres (4) mounted on a foil matrix (2) which are disposed between upper and lower pressure pads (34 and 36. The cell sandwich (32) is then heated (e.g.. to about 530°C). The spheres (4) are then affixed to the foil matrix (2) by directing the all sandwich (32) through a roll press (48) which compresses the heated cell sandwich (32).

Procédé perfectionné de fixation de sphères (4) sur une matrice (2) sous forme de feuille consistant d'abord à préparer une cellule sandwich (32) comprenant des sphères (4) qui sont montées sur ladite matrice (2) et disposées entre des coussins (34 et 36) de pression supérieur et inférieur, puis à chauffer la cellule (32) (par exemple jusqu'à environ 530 DEG C). Les sphères (4) sont alors fixées sur la matrice (2) en dirigeant la cellule (32) à travers un laminoir (48) qui comprime la cellule (32) chauffée.
