Abstract

A plastics laminated fabric membrane, such as used for gas meters, has a central portion 12, offset to one side of the plane of a peripheral flange 11, and a convergent portion 14, interconnecting the flange 11 and portion 12, provided with a plurality of indentations 23, or 27, 271, Fig. 5, which overlap one another in the direction of the convergent portion 14.
