PROBLEM TO BE SOLVED: To provide a laminate molding method of a rubber strip capable of enhancing the quality of a laminate molding member by grinding down the stepped part of the rubber strip material spirally wound around a core drum in a sufficiently effective manner. SOLUTION: In the laminate molding method of the rubber strip for spirally winding the rubber strip material 1 extruded from an extruder around a rotating core drum while partially superposing the same on the core drum to mold the laminate molding member, a grinding-down roller 20, which is rotationally driven itself to grind down and bond the stepped part 1d, which is formed by partially superposing the rubber strip material 1, is provided. The grinding-down roller 20 is constituted so as to grind down the stepped part 1d to be ground down so that the synthetic speed vector V of the drum peripheral speed vector Vd accompanied by the core drum in the stepped part 1d to be ground down and the roller peripheral speed vector Vr accompanied by the rotation of the grinding-down roller 20 is turned toward the rubber strip material precedently wound in the direction almost right-angled to the winding direction of the rubber strip material 1 and the direction and rotational speed of the roller 20 are set.
