Abstract

The apparatus has a cylindrical housing with an opening at an end face for introducing and removing workpieces (4). The workpieces are held between support plates (6, 7) and air-guiding plates (14, 15) that are formed adjacent the support plates for exposing the workpieces to cooling gas conveyed by blowers (10, 11). Reversing flaps (18-21) arranged at upper and lower ends of the guiding plates control the flow of cool gas.
