ABSTRACT:
A multi-cell gas-filled bag adapted for a dock fender, a connector for lighters and a float for supporting sand-flash pipe in reclaiming can be produced in a simple manner by uniting an inner sleeve made of an elastic rubber, and an outer sleeve made of an elastic rubber, each including a reinforcing material embedded therein, at a plurality of adhering circumferentially spaced longitudinal contact portions of the inner and outer sleeves, and introducing gas into non-adhering portions formed between adjacent adhering portions of the inner and outer sleeves to form cavities filled with the gas by the deformation of the inner sleeve.
