Abstract
A tire curing apparatus in which a number of mobile curing units, each designed to house a respective green tire, are selectively and independently fed along a loop circuit having at least two parallel branches, the ends of which branches are connected to a common section extending through a station for loading and unloading tires on and off respective curing units; each curing unit incorporating a mold for a respective green tire, a closed pneumatic circuit designed to receive, at the loading/unloading station, a given supply of curing medium under pressure, a fan device for force circulating the curing medium supply inside the pneumatic circuit, and individual elements for heating both the mold and the curing medium supply.
Claims11
A tire curing apparatus comprising a number of mobile curing units, each designed to receive a respective green tire;
- loading means and unloading means for respectively loading said tires on and unloading said tires off respective ones of said curing units, inclined guide means defining a loop path for said mobile units;
- said path extending between said loading means and said unloading means;
- means for feeding the said units along the said path;
- and individual coupling means provided on each said curing unit for releasably and independently coupling the same to said guide means;
- each of said curing units incorporating a mold for a respective green tire, a closed circuit means designed to receive, at the said loading means, a given supply of curing medium under pressure, means for circulating the said curing medium supply inside the said closed circuit means, and individual heating elements for both the said mold and the said curing medium supply.
A tire curing apparatus comprising a number of mobile curing units, each designed to receive a respective green tire, means for loading and unloading the said tires on and off respective ones of said mobile curing units cooperating with an inclined loop track for the said units, said track including at least two branches arranged in parallel, means for selectively feeding the said units along the said track and switching means for selectively excluding one of the said two branches;
- each of said curing units incorporating a mold for a respective green tire, a closed pneumatic circuit means designed to receive at the said loading and unloading means, a given supply of curing medium under pressure, a fan device for force circulating the said curing medium supply inside the said closed pneumatic circuit means, and individual elements for heating both the said mold and the said curing medium supply.
