Method for producing a moulded rubber seal

Abstract

A method is provided for producing centering elements in a molded rubber seal that is reinforced with metal. Metal is cut out of at least one edge area of the metal element and the freed material is shaped by being bent upwards away from the plane of the metal element. Elastomer material is then molded around the bent material above the cavity created by the shaping process, in order to produce a pre-definable final contour.

1 . Procedure for the production of centering agents in the field of metallically strengthened rubber mold gaskets, in which in a border area of a metal element at least one free cut is made and material of the metal element bent out of a plane of the metal element to create a free space; introducting elastomer material into the free space and around the outwardly bent material during the formation of elastomeric sealing features of the gasket.  
   
   
       2 . Procedure according to  claim 1 , wherein the material is bent 90° from the plane of the metal element.  
   
   
       3 . Procedure according to  claim 1 , wherein the bent material is formed with polygonal cross section of the metal element and afterwards molded to a substantially circular cross section with elastomer material.
