METHOD FOR ATTACHING APEX OF A BEAD FOR MANUFACTURING A TIRE, CAPABLE OF IMPROVING THE QUALITY OF THE TIRE AND INCREASING PRODUCTIVITY

摘要

PURPOSE: A method for attaching apex of a bead for manufacturing a tire is provided to prevent the edge of the apex from being bent by finally attaching the apex to the bead after making a linear apex into a spiral circular body by moving a strew type conveyor.;CONSTITUTION: A method for attaching apex comprises the following steps: a step(S201) which linearly extrudes apex having a cross section of a right triangle; a step(S301) putting the extruded apex to a screw type conveyor; a step(S401) forming the apex which is loaded to a conveyor into a spiral circular body by expanding an outer diameter of the screw type conveyor in a constant rate; and a step(S501) attaching the aped and a bead by continuously supplying the apex to a device for attaching the apex.;COPYRIGHT KIPO 2010
