The invention relates to a device comprising a receiving device () for post-treating tires (). After vulcanizing the elastomer material, the tires () are subjected to internal pressure by means of support gas, and cooled. Said receiving device () is embodied such that it can maintain the tires () and also seal the inner chamber of the tires. Also, a pressurized gas supply is connected to the receiving device (). Said receiving device () comprises at least two fixed receiving areas () for at least two tires (). The tires undergo at least one introduction process using a positionable handling device ().

Device for post-treating tyres

A bladderless tire-curing press has upper and lower pressing disks cooperating with upper and lower bead rings. The pressing disks have circumferentially continuous outer surfaces engaging the beads and bounded inwardly by axial projections with conical centering surfaces which engage in recesses in the bead rings. The bead rings have projections engaging in grooves between the projections of the disks.

Bladderless tire-curing press

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.

Apparatus for charging a tire heating press

A loading process for a heated tire press is described herein in which a loader takes an unfinished tire from an unfinished tire stand and puts it between the tire forming pieces of the tire press. This loader travels with folded-in clamp jaws into the inside of the unfinished tire from below, engages it with extended clamp jaws inside of the upper bead from below, transports it in this position to the upper tire forming piece and raises it until its upper bead presses against the upper rim ring on the upper tire forming piece. The upper bead is held there by an auxiliary bellows, retaining fastener or the like. Subsequently the clamp jaws are folded in again and the loader retracted.

Process and apparatus for loading a tire press

A time curing press includes an upper mold part which is movably arranged by means of long-stroke cylinders relative to a lower mold part. Extending at a central area of the upper mold part and connected thereto is a vertical guide bar which is supported in a headpiece of the frame of the press. The guide bar is provided with a vertically adjustable not which is engaged by clamp jaws to lock the mold, i.e. the upper mold part with the lower mold part in the closed position of the press.
