PROBLEM TO BE SOLVED: To provide a rubber roll manufacturing apparatus capable of forming a hollow portion in which the space occupied by a core grid is hollowed with a rubber material, at intervals within a predetermined range.SOLUTION: The rubber roll manufacturing apparatus is constituted to include: a discharge unit 12 for alternately discharging a rubber roll portion 56 in which the outer peripheral surface of a core grid 22 is cladded with rubber material, and a hollow portion 58 in which the space occupied by the core grid 22 is hollowed with rubber material, obtained by successively feeding the core grid 22 at intervals to the central part of the cylindrically extruded unvulcanized rubber material; and an auto-running inhibiting member 72 for inhibiting the auto-running of the core grid 22 on the downstream side of the feeding direction of the core grid 22, into said feeding direction, when forming the hollow portion 58 in which the space occupied by the core grid 22 is hollowed with rubber material. |
