Method and apparatus for making sealing rings of the radial type with sealing lip of fluoroplastic

Image Number 3 for United States Patent #5009742.

The invention relates to a sealing ring of the radial type comprising a reinforcement, a body, particularly of elastomer, and a sealing lip consisting of an annular washer, of fluoroplastic such as PTFE, made to adhere along an outside peripheral annular zone by one of its faces on an upper bearing surface of the body.The washer is subjected to a chemical attack treatment aimed at reducing its antiadhesive properties only over an outside annular peripheral zone, the radial area of the outside zone corresponding to the radial area of the upper bearing surface of the elastomer body of a ring on which the sealing lip is made to adhere.
