The plant is characterised by a unit 1 that automatically applies the filler to the rubber coated metallic rings and by an apparatus 9 that automatically feeds the rubber coated metallic rings and that takes back the metallic rings once the filler has been applied on them. Same apparatus 9 transfers the rings with filler to the unit 11, which feeds the assembling unit of the tyres.

A succession of superposed digitized sections of an object are produced from a three-dimensional representation of the object. A powder or a mixture of powders is spread in the form of a fine layer and heated to a temperature close to solid phase sintering temperature of the powder or the mixture of powders. The layer is brought to the sintering temperature by scanning with a laser beam the layer ...
