Disclosed is a method for controlling a conveyor for conveying hollow bodies through a hollow-body heating station including: —a heating tunnel defining a heating path, —a conveyor including at least one travel track and shuttles capable of moving along the track while picking up at least one hollow body, the movement of each shuttle being controlled individually, —a travel-track loading portion on which two consecutive shuttles move at a first predetermined input separation, and a travel-track unloading portion. Two consecutive shuttles moving on this unloading portion are spaced apart by a predetermined output separation that is different from the first input separation.
