ABSTRACT:
In order to make a synthetic membrane for a gas meter of the measuring chamber type, an initial structure (10) of polyester fibers (11), which are preferably woven, is placed between two films (26, 28) of hot meltable elastomer (polyurethane). The hot meltable material is raised to its softening temperature and pressure is applied to cause the films (26, 28) to adhere to the woven structure (10).
