ABSTRACT:
An elastic supporting and sealing member, for mutually supporting a first body and a second body, and for sealing the gap between the first body and the second body, includes a first portion and a second portion of wire net and a piece of thermal foaming material, between the first and the second wire net portion, which expands and foams when it is heated up. A method of making such a member includes the steps of flattening a tubular shaped piece of wire net, and of introducing a strip shaped piece of such thermal foaming material between the two sides of the flattened tube of wire net, so that the longitudinal directions of the strip shaped piece of thermal foaming material and of the flattened wire net tube substantially coincide.
