METHOD FOR IMPROVING THE MECHANICAL AND SEALING PROPERTIES OF ELASTOMER SEALS, AND SEALS PRODUCED BY THIS METHOD.

摘要

The process for manufacturing sealing packings according to the invention comprises a preparation phase for an elastomer in which fibres (14, 32), for example cellulose fibres or aramide fibres, are added and a shaping phase involving a process for causing the elastomer to flow so as to obtain a preferential alignment of the fibres (14, 32) inside the joint produced. This process makes it possible to obtain a joint in which the fibres can be aligned parallel to the contact surface of this joint which ensures dynamic sealing.
