Abstract
In a process for heating an object made of thermoplastic material along a predetermined zone, a ring of burners arranged in series is guided along the zone and heats this zone, the zone forming a closed path and approximately matching the outer contour of the object; in a device for implementing the process, series-arranged burner units circulate on a path covering the zone to be heated, the units being guided along a closed loop.
