Description

       

      Separator    für elektrische Sammlerbatterien    Die Erfindung betrifft einen     Separator     für elektrische Sammlerbatterien, der aus  einem gewellten Blatt gelochten Kunststoffes  und einem ebenen Blatt zusammengesetzt ist,  das mit dem gewellten Blatt entlang der Be  rührungslinien der Wellen mit dem ebenen  Blatt verklebt ist.  



  Ein besonders brauchbarer     Separator     dieser bekannten Art ergibt sich, wenn gemäss  der     Erfindung    für das ebene Blatt poröses,  säurefest. imprägniertes Papier verwendet  wird.  



  Auf der Zeichnung ist ein Ausführungs  beispiel des     Erfindungsgegenstandes    darge  stellt.  



       Fig.    1 zeigt eine Ansicht des     Separators,     wobei das Papierblatt über einen Teil der       Separatorfläche    entfernt ist.  



  Füg. 2 stellt in grösserem Massstab einen       Teilqnersehnitt        @        ,durch    den     Separator    längs  der Linie     II-II    in     Fig.    1 dar.  



  Mit 1. ist ein gewelltes und gelochtes Blatt  aus     Polyvinylchlorid,    das beispielsweise     -unter     der geschützten Wortmarke      Igelit     gehandelt       wird,    bezeichnet. Ferner bezeichnet 2 ein Blatt  aus porösem, säurefest     imprägniertem    Papier  von weniger als 0,6 mm Dicke. Als besonders       geeignet    hat sieh eine Dicke des Papiers von  etwa 0,4 mm erwiesen. Beide Blätter sind auf  einandergelegt und an den Berührungslinien  der Wellen verklebt.

   Das Verkleben wurde auf       thermischem    Wege ohne zusätzliche Klebe  mittel durchgeführt, und zwar derart, dass  das aus thermoplastischem Kunststoff beste-         hende    gewellte Blatt entlang den Berührungs  linien der Wellen so lange erwärmt wird, bis  der Kunststoff erweicht. Dann wird das ge  wellte Blatt gegen das ebene Papierblatt ge  drückt und in dieser Stellung so lange gehal  ten, bis der Kunststoff wieder erstarrt, ist.  



  Die     Anwendung    des Papierblattes ergibt  besonders gleichmässige Verhältnisse für den  Stromdurchgang.



      Separator for electrical storage batteries The invention relates to a separator for electrical storage batteries, which is composed of a corrugated sheet of perforated plastic and a flat sheet which is glued to the corrugated sheet along the lines of contact of the waves with the flat sheet.



  A particularly useful separator of this known type is obtained if, according to the invention, the flat sheet is porous and acid-resistant. impregnated paper is used.



  In the drawing, an execution example of the subject invention is Darge provides.



       Figure 1 shows a view of the separator with the paper sheet removed over part of the separator surface.



  Add. 2 shows, on a larger scale, a partial cross section @ through the separator along the line II-II in FIG.



  1. A corrugated and perforated sheet of polyvinyl chloride, which is traded under the protected word mark Igelit, for example, is designated. Furthermore, 2 denotes a sheet of porous, acid-proof impregnated paper less than 0.6 mm thick. A thickness of the paper of about 0.4 mm has proven to be particularly suitable. Both sheets are placed on top of each other and glued to the lines of contact between the waves.

   The gluing was carried out thermally without additional adhesive, namely in such a way that the corrugated sheet made of thermoplastic material is heated along the lines of contact of the waves until the plastic softens. Then the ge corrugated sheet is pressed against the flat sheet of paper and held in this position until the plastic solidifies again.



  The use of the paper sheet results in particularly uniform conditions for the passage of current.
