Abstract: Containers are conveyed through an oven on a conveyor to cause a foamable material on each container to foam and become a heat insulative layer. The containers are supported on respective holders of the conveyor, which prevent the containers from contacting one another. Preferably, the holders support the containers loosely, to enable the containers to wobble relative to the holders under the influence of oven air currents and conveyor vibration. The holders thus do not make contact with any given point on their respective containers for a time period that is sufficient to enable the holders to draw enough heat away from the container to adversely affect the foaming operation. The containers are conveyed in single file, along a serpentine path through the oven.
