Heat Resistant Laminated Conveyor Belt and Manufacturing Method Thereof

A heat resistant laminated conveyor belt comprising a belt core layer made by a heat resistant non-metallic fiber substrate being impregnated with a fluororesin dispersion and then dried and sintered and a surface layer formed on said belt core layer via an adhesive layer made by a fluororesin film, said surface layer having a fabric structure using an element wire or wires made of at least one of a non-ferrous metal, inorganic compound, organic compound and carbon or having a structure in which said element wire or wires are arranged together.

A heat resistant laminated conveyor belt comprising a belt core layer made by a heat resistant non-metallic fiber substrate being impregnated with a fluororesin dispersion and then dried and sintered, an intermediate layer laminated on said belt core layer via an adhesive layer made by a fluororesin film, said intermediate layer being made by a heat resistant non-metallic fiber substrate being impregnated with a fluororesin dispersion and then dried and sintered, and a surface layer laminated on said intermediate layer via an adhesive layer made by a fluororesin film, said surface layer having a fabric structure using an element wire or wires made of a ferrous metal or having a structure in which said element wire or wires are arranged together.
