PROBLEM TO BE SOLVED: To suppress the formation of turbulence in a roll shape.SOLUTION: Provided is a rubber roll production device including: an extrusion part of cylindrically extruding an unvulcanized rubber material; a feed part of, in such a manner that the cylindrical rubber material is extruded from the extrusion port of the extrusion part in a state where it covers the outer circumference of a core material, feeding the core material into the rubber material; a grasping member of, in a state where the removal part from which the rubber material is removed in the tip side of the core material is projected from the extrusion port by a length in the axial direction or lower, grasping the removal part; and a movement mechanism of moving the grasping member to the extrusion direction of the extrusion part in accordance with the extrusion of the rubber material from the extrusion port. 【課題】ロール形状に乱れが生じるのを抑制する。【解決手段】未加硫のゴム材を円筒状に押し出す押出部と、円筒状の前記ゴム材が芯材の外周を被覆した状態で前記押出部の押出口から押し出されるように、前記ゴム材の内部に前記芯材を供給する供給部と、前記芯材の先端側において前記ゴム材が除去される除去部分がその軸方向長さ以下だけ前記押出口から突出した状態で、当該除去部分を把持する把持部材と、前記押出口から前記ゴム材が押し出されるのに伴って、前記押出部の押出方向へ前記把持部材を移動させる移動機構と、を備える。【選択図】図４
