ABSTRACT:
A method for production of lined gaskets or gasket inserts with which a pasty substance is arranged between the sealing surfaces (or correspondingly developed forms) and separated from these by two external layers, and hardened between the form-producing sealing surfaces. The pasty substance preferably contains a filler of quartz powder whose void fraction is filled with a 2-component artificial resin. The pasty substance can be applied with the assistance of a spray gun. A preferred form of construction of such a gasket contains a hardened material layer and a corrugated ring adjoining it, which, along an inner peripheral area are surrounded by a band-shaped shell and are arranged between two gasket insert rings, which for their part are surrounded by a customary shell of polytetrafluoroethylene or such-like. The production of gaskets of this type can take place at the point of use with the aid of simple means, so that costly operational interruptions can be shortened without expensive fitting operations or a re-ordering from a manufacturer being necessary.
