PURPOSE: An apparatus and a method for manufacturing extrusion molding belts for producing hoses of a vacuum cleaner are provided to prevent the defects of products by maintaining the regular intervals of hollow protrusions and cooling a pressing mold band. CONSTITUTION: A method for manufacturing extrusion molding belts for producing hoses of a vacuum cleaner comprises following steps. A row of a pressing mold band(1) is shaped on an extrusion dice(4), and multiple hollow projections are integrated with the pressing mold band. The pressing mold band exhausted from the extrusion dice passes through a guide path of a guide dice(6) and then passes through a movable hole(11) of a shaping die(10). The movable hole is composed of grooves. Since pressing mold band passes through the cooling water, the regular intervals of multiple hollow projections are maintained, and the pressing mold band is cooled.
