METHOD FOR MANUFACTURING TIRE COMPONENT MEMBER

An object of the present invention is to form a tire component member having a desired shape by a ribbon winding method without depending on skill and experience of an operator. Test conditions including the number of windings of winding a ribbon rubber around a forming drum and a feed pitch for moving the ribbon rubber in an axial direction of the forming drum for each rotation of the forming drum are set (Step S11), and a test sample is prepared under the test conditions (Step S12). With respect to the prepared test sample, a width, a cross-sectional area, and a thickness distribution in a width direction are measured (Step S13). Based on these results, the test conditions are corrected to obtain a correction condition (Steps S14 to S19).
