  Verfahren zur Gummierung von Hoehdruckschäuehen. 



   Es ist bekannt, zu gummierende Waren auch mehrere Male mit Gummierungsmasse zu bestreichen. 



  Gemäss der Erfindung werden nun zwei Belagschichten verschiedener Zusammensetzung auf die Hanf-   schläuche   aufgebracht, was den Zweck hat Gummierungsschichten verschiedener Dichte übereinander auf dem Hanfschlauch hervorzubringen. Die auf dem Hanfmaterial zunächst liegende Schichte soll geringere Dichte aufweisen und dadurch   zusammendrückfähiger   sein als die sodann folgende Schichte, welche dem erhöhten Druck des durch den Schlauch getriebenen Mittels direkt ausgesetzt ist. Dies hat eine grössere Haltbarkeit und Dichtheit des so gummierten Schlauches zur Folge. Durch den Zusatz von Ocker zur Mischung für den ersten Belag und von Pudergraphit zur Mischung des zweiten Belages, wird dieser Dichteunterschied der beiden übereinanderliegenden Gummibeläge erzielt. 



   Die Wirkung wird noch dadurch verstärkt, dass man den zweiten Belag mit höherem Druck aufbringt, als der Aufbringdruck ist, den man bei Aufbringen des ersten Belages aufgewendet hat. 



   Gemäss der Erfindung besteht nun der erste Belag aus Benzol,   Rohgummi   und Ocker und der zweite Belag aus Benzol, Rohgummi und Pudergraphit. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Gummierung von Hochdruckschläuchen, bei welchem der Belag in zwei Schichten auf das Schlauchmaterial aufgebracht wird, dadurch gekennzeichnet, dass die erste Schichte aus Benzol, Rohgummi und Ocker und die zweite Schichte aus Benzol, Rohgummi und Pudergraphit besteht.

  Process for gumming high pressure shoes.



   It is known to coat goods to be gummed several times with gumming compound.



  According to the invention, two coating layers of different composition are then applied to the hemp hose, which has the purpose of producing rubber coating layers of different density on top of one another on the hemp hose. The layer initially lying on the hemp material should have a lower density and thus be more compressible than the layer which then follows, which is directly exposed to the increased pressure of the agent driven through the hose. This results in greater durability and tightness of the rubber-coated hose. By adding ocher to the mixture for the first covering and powder graphite to the mixture of the second covering, this difference in density between the two rubber coverings on top of one another is achieved.



   The effect is reinforced by the fact that the second coating is applied with a higher pressure than the application pressure that was used when the first coating was applied.



   According to the invention, the first coating now consists of benzene, raw rubber and ocher and the second coating consists of benzene, raw rubber and powdered graphite.



   PATENT CLAIMS:
1. A method for rubber coating high-pressure hoses, in which the coating is applied to the hose material in two layers, characterized in that the first layer consists of benzene, raw rubber and ocher and the second layer consists of benzene, raw rubber and powdered graphite.
