Claim:
A system for treating a plurality of workpieces, each workpiece comprising a first body having a thickness and a lateral area and a second body having a lateral area larger than the lateral area of the first body, the system comprising: four substantially identical stations, comprising a pair of loading stations and a pair of unloading stations, distinct from the loading stations, and each configured with an upper heat-transfer body and a lower heat-transfer body; a base, disposed between the lower heat-transfer bodies and the upper heat-transfer bodies; two nonoverlapping pairs of substantially identical sites on the base, arranged analogously to the stations, each site comprising a shelf having a horizontal ledge and a vertical wall, accommodating an interior space above the base, and configured to bear one of the workpieces, wherein the base is rotatable about an axis to align each of the pairs of sites in turn with the loading stations and the unloading stations, and the stations are operable simultaneously to lift respective lower heat-transfer bodies into respective interior spaces of respective aligned sites while heating the lower and upper heat-transfer bodies.
