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