Tire heating press

The invention relates to a device for preheating at least one mold for a tire heating press, which has a coupling for applying a heating medium to the mold. The mold to be heated is enclosed by a receiving container (), which is secured within a framework and creates the coupling for the heating medium. The device helps to provide effective preheating of the mold by an insulating shroud (), which is positioned over the receiving container () during the preheating process and reduces heat dissipation into the surroundings.
