To provide a multi-layer rubber member manufacturing apparatus and a multi-layer rubber member manufacturing method whereby, change of a cross-sectional shape, size, ratio of rubber regions or the like of the multi-layer rubber member is easily performed only by change of a die plate of each rubber extruder, thereby achieving reduction of equipment cost and improvement of productivity.SOLUTION: There is provided a multi-layer rubber member manufacturing apparatus that forms a multi-layer rubber member G0 in which a cross section thereof is divided into a first rubber region Y1, a second rubber region Y2, and a third rubber region Y3. The manufacturing apparatus comprises first to third conveyors 5 to 7 for respectively conveying first to third rubber bodies G1 to G3 from the first to third rubber extruders 2 to 4. The second conveyor 6 has a downstream end E2L that is interrupted above the first conveyor 5, and a two-layered rubber QA is formed by stacking the second rubber body G2 to be sent from the downstream end E2L on the first rubber body G1 of the first conveyor 5. The third conveyor 7 stacks the third rubber body G3 on the two-layered rubber QA to form the multi-layer rubber member Q0.SELECTED DRAWING: Figure 2 【課題】 多層ゴム部材の断面形状、サイズ、ゴム領域の比率等の変更を、各ゴム押出し機のダイプレートの変更のみで容易に行い、設備コストの低減や生産性の向上を図る。【解決手段】 断面が、第１ゴム領域Ｙ１と第２ゴム領域Ｙ２と第３ゴム領域Ｙ３とに区分された多層ゴム部材Ｇ０を形成する。第１〜３のゴム押出し機２〜４からの第１〜３ゴム体Ｇ１〜Ｇ３を、それぞれ搬送する第１〜３搬送コンベヤ５〜７を具える。第２搬送コンベヤ６は、下流側端部Ｅ２Ｌが第１搬送コンベヤ５の上方で途切れ、下流側端部Ｅ２Ｌから送り出される第２ゴム体Ｇ２を、第１搬送コンベヤ５の第１ゴム体Ｇ１上に重ね合わせて２層ゴムＱＡを形成する。第３搬送コンベヤ７は第３ゴム体Ｇ３を、２層ゴムＱＡ上に重ね合わせて多層ゴム部材Ｑ０を形成する。【選択図】図２
