Claim:
1. A method of producing a heat-resistant laminated conveyer belt which comprises a fluororesin-coated core obtained by impregnating an aramid fiber woven fabric with a fluororesin dispersion and drying and sintering the fabric; and a reinforcement layer which is formed on the core through an adhesive layer and obtained by impregnating an aramid fiber woven fabric to which stretch properties are applied with a fluororesin dispersion and drying and sintering the fabric; and wherein the aramid fiber woven fabric of the core is a woven fabric by a plain-weave seamless loom and the woven fabric includes an S-twist weft yarn and a Z-twist weft yarn which are alternatively arranged, and the method comprising: thermally compression molding the reinforcement layer in a thickness direction of the reinforcement layer before thermally pressing the core, the reinforcement layer, and the adhesive layer arranged between the core and the reinforcement layer.
