ABSTRACT:
A tire press for vulcanizing a tire includes two rotationally symmetrical vulcanizing tools which are situated inside the tire in the working position thereof and which have a tool diameter greater than the diameter of the tire. The tire press further includes an apparatus for introducing the tire into the tire press. The apparatus has a carrier; a moving and guiding mechanism for displacing the carrier parallel to the press axis and also in a plane perpendicular to the press axis between a tire-receiving position and a position at the vulcanizing tools; an auxiliary frame mounted on the carrier to be pivotal with respect thereto about an axis perpendicular to the press axis; and a tool mounted on the auxiliary frame for grasping one of the two tire beads. There are further provided spreading arms attached to the auxiliary frame; spreading shoes mounted on the spreading arms for grasping the other of the two tire beads; and a mechanism for moving the spreading arms away from one another to a distance exceeding an outer diameter of the tire.
