Abstract

La présente invention est pourvue d'un élément de réception de pression (12) (rouleau de réception de pression (44)), d'un rouleau de pression (14), d'un générateur de force magnétique (15a), et d'un dispositif de chauffage (15b). Le rouleau de réception de pression (44) est positionné en contact étroit avec la surface arrière (1a) d'un matériau (1) à assembler constitué d'un corps non magnétique, dans une plage de jonction (4) dans laquelle le matériau (1) à assembler et un matériau de jonction (2) sont chacun superposés l'un sur l'autre par l'intermédiaire d'un adhésif (3). Le rouleau de pression (14) a une surface circonférentielle externe (14a) destinée à venir en contact étroit avec la surface du matériau de jonction (2), et est conçu de façon à pouvoir rouler le long d'une surface de matériau de jonction (2a). Le générateur de force magnétique (15a) génère une force de pression sur une partie prise en sandwich (5) prise en sandwich par la surface circonférentielle externe (14a) et l'élément de réception de pression (12). Le dispositif de chauffage (15b) chauffe la partie prise en sandwich (5).
