Method and device for post-treating tyres

A device for post-treating tyres after a vulcanization process, comprising:

• at least one post-cure inflator (PCI) for pressurizing an interior of the tyre with support gas during a tyre cooling phase;
• and, a post-cure device (PCD) that at least partially surrounds the at least one PCI, wherein the PCD has at least one insulating chamber for accommodating at least one tyre and the insulating chamber has structurally produced insulating properties by virtue of a double-walled construction to ensure slow cooling, defined as cooling lasting at least 20 minutes, of the tyre from a first to a second temperature level, wherein an interior of the insulating chamber is temperature-controlled by a temperature control medium that circulates within the double-walled construction, wherein the insulating chamber is constructed from at least one first chamber element and one second chamber element movable in an axially linear manner relative to one another in a vertical direction along a longitudinal vertical axis of the device, wherein the first chamber element provides a top part of the insulating chamber and the second chamber element provides a bottom part of the insulating chamber, and wherein a third chamber element formed as a concentric ring is arranged between the first chamber element and the second chamber element, wherein the concentric ring is concentric with the first and second chamber elements, wherein the first chamber element is arranged vertically above the second chamber element, and wherein the third chamber element is movable in the vertical direction, wherein the third chamber element forms a portion of a wall of the insulating chamber at least in a closed state of the insulating chamber.
