Abstract
A manufacturing apparatus of a rubber member includes an extruder that kneads and feeds a rubber material; a mouthpiece that discharges the rubber material supplied from the extruder; a support member that has a support surface opposing the mouthpiece; a rubber collection chamber that is formed between the mouthpiece and the support surface, that collects the rubber material discharged from the mouthpiece, and that has an opening in a front movement direction of the support surface with respect to the mouthpiece; and a shutter that opens and closes the opening. A plate-like rubber member is molded using the rubber material discharged from the mouthpiece onto the support surface by relatively moving the support surface and the mouthpiece.
