Abstract
A method of manufacturing a contact body is disclosed wherein the contact body is built up of thin layers of hydrated asbestos fibers shaped between mutually spaced support positions to form channels extending from end to end of the contact body. The layers have a coating thereon of at least one inorganic substance and the layer body is heated to at least the dehydration temperature of the asbestos, at which the water of crystallization is released by passing a current of hot gas through the channels in the contact body for a relatively short period of time in order to effect the intended action on the body.
