Abstract

Dans le procédé selon l'invention, on dispose en sandwich des bandes de papier 6a entre deux bandes de matière thermoplastique 30,31 que l'on accole en les faisant avancer entre des rouleaux presseurs chauffés 38,39, on découpe des fenêtres 43 destinées à recevoir les composants électro-chimiques actifs des éléments de la batterie, on ferme les fenêtres à l'aide d'éléments de séparation 45 et on obtient ainsi une série d'éléments de batteries électriques dont les bandes incorporées 6a constituent les moyens d'aeration qui évacuent les gaz vers l'extérieur et laissent entrer l'oxygène.In the method according to the invention, strips of paper 6a are sandwiched between two strips of thermoplastic material 30, 31 which are joined by making them advance between heated pressure rollers 38, 39, windows 43 intended for to receive the active electro-chemical components of the battery elements, the windows are closed using separating elements 45 and thus a series of electric battery elements is obtained, the incorporated bands 6a of which constitute the means of aeration which evacuates the gases to the outside and lets in oxygen.
