Abstract

LA UNION DE LAS HOJAS ELASTOMERICAS (82A, 82B) INCLUYE EN SUMINISTRAR UNA SUPERFICIE DE SOPORTE (22) CON UNA CAVIDAD (62) DENTRO DE ELLA. LAS PORCIONES FINALES (102, 104) DE LAS HOJAS ELASTOMERICAS (82A, 82B) SE SUPERPONEN DE TAL MODO QUE CADA PORCION FINAL FRANQUEA LA CAVIDAD (62). HAY UNA HERRAMIENTA (24) EN UN LADO DE LAS HOJAS ELASTOMERICAS OPUESTAS A LA CAVIDAD (62). UNA PARTE DE LA HERRAMIENTA (24) ENTRA EN LA CAVIDAD (62) PARA DEFORMAR LAS PORCIONES FINALES (102, 104) DE LAS HOJAS ELASTOMERICAS (82A, 82B) Y FORMAR UNA JUNTA QUE TENGA UN GROSOR MENOR QUE EL GROSOR COMBINADO DE LAS PORCIONES FINALES DE LAS HOJAS ELASTOMERICAS ANTES DE LA DEFORMACION.
