Description

       

  



  Elektrisch geheiztes   Presspolster    zum Anvulkanisieren von Gummisohlen    an Schuhoberteile.   



   Beim Ankleben von Gummisohlen an den Schuhoberteil wird die Sohle durch eine Membrane angedrückt, welche durch PreBluft aufgebläht wird, sich an die gesamte Fläche der Sohle anschmiegt und den erforderlichen Druck ausübt. Um die Zeit, während welcher die Sohle unter Druck gehalten werden muss, zu verkürzen, wird die den Druck aus  übende    Membranoberfläche geheizt. Durch die Wärme wird das Trocknen des   Klebstof-    fes beschleunigt und dadurch die Zeit des Andrückens der Membrane verkürzt. Die erforderliche Temperatur für die üblichen Klebstoffe beträgt 60 bis 80  C, Die   Mem-    brane besteht gewöhnlich aus Gummi mit einer eingebauten elektrischen Heizeinlage.



   Das Befestigen von Gummisohlen an   Schuhoberteilen    durch Anvulkanisieren findet in derselben Weise statt wie das Ankleben. Nur in den angewendeten Temperaturen besteht ein Unterschied.



   Das Kleben kann bei beliebiger Temperatur bis zu   80  C    vor sich gehen, ohne Berücksichtigung der erforderlichen Zeit. Das Anvulkanisieren von Gummisohlen kann aber nur bei Temperaturen über   120  C    stattfinden und bei diesen Temperaturen wird die Membrane in kurzer Zeit unbrauchbar.



   Die Erfindung ermöglicht das Anvulkanisieren von Gummisohlen an Schuhoberteile ohne Beschädigung der Membrane und betrifft ein elektrisch geheiztes PreBpolster zum Anvulkanisieren von Gummisohlen an   Schuhoberteile,    bei welchem ein aus   Metall-    gewebe bestehender Heizkörper auf der Au ssenfläche der Presspolstermembrane   angeord-    net ist, zum Zwecke, dass der Heizkörper beim Anvulkanisieren die Gummisohle unmittelbar berührt. Der Heizkörper ist aus Metallgewebe hergestellt, was ermöglicht, dass er sich vollkommen an die Fläche der Sohle anschmiegt.



   Durch die unmittelbare Berührung des Heizkörpers mit der Sohle wird die zum Anvulkanisieren der Sohle erforderliche Wärme fast ohne Verluste auf die Sohle übertragen. 



  Durch das Eindrücken des Heizkörpers in die durch die Erhitzung am Anfang der Vulkanisation weich gewordene Gummisohle können durch entsprechende   Heizkorperfor-    men die Sohlen mit Zeichen, z. B. Verzierungen mit   Aufschriften,    Zahlen oder Buchstaben, versehen werden.



   In der Zeichnung ist ein   Ausführungs-    beispiel des Erfindungsgegenstandes dargestellt.



   Der Raum   1    für das Druckmittel (z. B.



  Pressluft) ist durch ein flaches Gefäss 2 und durch eine das Gefäss abschliessende Membrane 3 begrenzt. Auf dieser Membrane ist der Heizkörper 4 mit den Anschlägen 6 für den auf den Leisten aufgezogenen Schuhoberteil mit der Sohle 5 angebracht.



  



  Electrically heated press pad for vulcanizing rubber soles onto shoe uppers.



   When rubber soles are glued to the upper part of the shoe, the sole is pressed on by a membrane which is inflated by compressed air, clings to the entire surface of the sole and exerts the required pressure. In order to shorten the time during which the sole has to be kept under pressure, the membrane surface exerting the pressure is heated. The heat accelerates the drying of the adhesive and thus shortens the time it takes to press the membrane. The required temperature for the usual adhesives is 60 to 80 C. The membrane is usually made of rubber with a built-in electrical heating element.



   The fastening of rubber soles to shoe uppers by vulcanization takes place in the same way as gluing. There is only a difference in the temperatures used.



   Gluing can take place at any temperature up to 80 C, regardless of the time required. The vulcanization of rubber soles can only take place at temperatures above 120 C and at these temperatures the membrane becomes unusable in a short time.



   The invention enables rubber soles to be vulcanized onto shoe uppers without damaging the membrane and relates to an electrically heated PreBpolster for vulcanizing rubber soles onto shoe uppers, in which a heating element made of metal fabric is arranged on the outer surface of the press pad membrane for the purpose of the heating element touches the rubber sole directly during vulcanization. The radiator is made of metal mesh, which allows it to nestle completely against the surface of the sole.



   Due to the direct contact between the heating element and the sole, the heat required to vulcanize the sole is transferred to the sole with almost no loss.



  By pressing the heating element into the rubber sole, which has become soft as a result of the heating at the beginning of vulcanization, the soles with symbols, e.g. B. decorations with inscriptions, numbers or letters are provided.



   The drawing shows an exemplary embodiment of the subject matter of the invention.



   Room 1 for the pressure medium (e.g.



  Compressed air) is limited by a flat vessel 2 and a membrane 3 that closes the vessel. The heating element 4 with the stops 6 for the shoe upper with the sole 5 is attached to this membrane.
