  • Method for manufacture of diaphragm and apparatus therefor
    Patent number: 4904318
    Abstract: A method and apparatus for the manufacture of a diaphragm from a fabric-containing sheet (material). The fabric-containing sheet produced by an extrusion molding machine in a width which is a multiple of the diameter of diaphragms to be manufactured is continuously fed in fixed pitches to a press vulcanizing device and an punching device, to permit automation of the manufacture of diaphragms and an appreciable reduction in the number of steps. This method, thus, improves the yield of materials used, permits down sizing of the production equipment, and reduces the motive power consumption.
