Method for controlling a conveyor for conveying hollow bodies through a heating station for an installation for manufacturing containers made of thermoplastic material, having: - a heating tunnel defining a heating path; - a conveyor having at least one running rail forming a circuit and shuttles that are able to circulate along the rail while carrying at least one hollow body , each shuttle being commanded for movement individually, the rail having a heating section for transporting the hollow bodies along the heating path; - a device for inputting the hollow bodies to be heated that brings the hollow bodies as far as a loading section of the running rail so as to load them onto the shuttles , two successive shuttles circulating with a determined first, input spacing (E1) on this loading section ; - a device for outputting the hot hollow bodies that recovers the hollow bodies carried on the shuttles circulating on an unloading section of the running rail ; wherein: at least from their entry on the heating section , the shuttles are controlled so that the spacing between two successive shuttles is reduced with respect to said first, input spacing (El); when the shuttles arrive on the unloading section , they are controlled so that two successive shuttles circulate with a determined third, output spacing (E3); the spacing between two shuttles remains reduced with respect to said first, input spacing (E1) as long as they are circulating on the heating section ; the spacing between two successive shuttles remains equal to a second, constant spacing (E2) as long as they are circulating on the heating section ; the second, heating spacing (E2) is smaller than the first, input spacing (E1) and the third, output spacing (E3) . - a heating tunnel defining a heating path; - a conveyor having at least one running rail forming a circuit and shuttles that are able to circulate along the rail while carrying at least one hollow body , each shuttle being commanded for movement individually, the rail having a heating section for transporting the hollow bodies along the heating path; - a device for inputting the hollow bodies to be heated that brings the hollow bodies as far as a loading section of the running rail so as to load them onto the shuttles , two successive shuttles circulating with a determined first, input spacing (E1) on this loading section ; - a device for outputting the hot hollow bodies that recovers the hollow bodies carried on the shuttles circulating on an unloading section of the running rail ; at least from their entry on the heating section , the shuttles are controlled so that the spacing between two successive shuttles is reduced with respect to said first, input spacing (El); when the shuttles arrive on the unloading section , they are controlled so that two successive shuttles circulate with a determined third, output spacing (E3); the spacing between two shuttles remains reduced with respect to said first, input spacing (E1) as long as they are circulating on the heating section ; the spacing between two successive shuttles remains equal to a second, constant spacing (E2) as long as they are circulating on the heating section ; the second, heating spacing (E2) is smaller than the first, input spacing (E1) and the third, output spacing (E3) . <EOS>
