Abstract
An apparatus for cooling tires at the end of their vulcanization which includes: a frame having a base intended to be mounted on the ground, defining a horizontal orientation; two shafts mounted for rotation on said frame, substantially parallel to each other and substantially parallel to the horizontal, at a distance from each other less than the outside diameter of the tires to be handled; a drive for rotating at least one of the two shafts; so that, when a tire is placed on said shafts with the axis of rotation of said tire arranged substantially parallel to the axes of said shafts, said drive for placing in rotation being activated, said tire is subjected to a gyroscopic force and remains in equilibrium.

An apparatus for the cooling of vulcanized tires comprising:
- a frame comprising a base intended to be firmly mounted on the ground, defining the horizontal direction;
- two shafts mounted for rotation on said frame, substantially parallel to each other and substantially parallel to the horizontal, at a distance from each other less than the outside diameter of the tires to be cooled;
- means for placing at least one of the two shafts in rotation;
- wherein each shaft includes at least one group of two adjacent frustoconical bearing surfaces inclined towards each other, the groups of each of the shafts being disposed facing each other so as to define a groove receiving a tire, so that, when a tire is disposed on said shafts with the axis of rotation of said tire arranged substantially parallel to the axis of said shafts, said means for placing in rotation being activated, said tire is subjected to a gyroscopic force and remains in equilibrium and is subjected to forced heat exchanges to cool the tire.
A process for the cooling of a tire after the vulcanization thereof, comprising the following steps:
- using two rotary shafts substantially parallel to each other and arranged at a distance from each other less than the outside diameter of the tires to be handled, the axis of said shafts being disposed substantially perpendicular to the direction of gravity, each shaft including at least one group of two adjacent frustoconical bearing surfaces inclined towards each other, the two groups of each of the shafts being disposed facing each other so as to define a groove receiving a tire;
- placing at least one of the two shafts in rotation;
- depositing at least one tire at a temperature close to the vulcanization temperature on said shafts, disposing the axis of rotation of said tire substantially parallel to the axis of said shafts;
- so that the rotation of the shaft causes the placing in rotation of the tire to produce a gyroscopic effect sufficient to maintain the tire in equilibrium and a heat exchange by forced convection to cool the tire.
An apparatus for the cooling of vulcanized tires comprising a pair of longitudinally extending rotatable, parallel shafts for supporting a cured tire during cooling, said shafts having a loading end and a discharge end, means for driving at least one of the two shafts at a speed necessary to subject the tire to a gyroscopic force so that the tire remains in equilibrium on the shafts, and means for displacing a rotating tire in equilibrium longitudinally along said rotating shafts from the loading end toward the discharge end for cooling the tire.
A method for the cooling of vulcanized tires comprising supporting a cured tire for cooling on a pair of longitudinally extending rotatable, parallel shafts, loading a cured tire to be cooled at a loading end of said shafts, driving at least one of the two shafts at a speed necessary to subject the tire to a gyroscopic force so that the tire remains in equilibrium, and displacing a rotating tire in equilibrium longitudinally along said rotating shafts toward a discharge end for cooling the tire.
