Abstract
An appliance for the simultaneous tempering and processing of a plurality of process items with the aid of electromagnetic radiation. The appliance is a stack oven, the process items and the energy sources being arranged on one another in such a way that a process item is present between two energy sources and an energy source is present between two process items. The appliance is particularly suitable for tempering the process items in the presence of a process gas. Using the appliance, a variable heating and cooling profile with variable process parameters is possible. In particular, reliable tempering of a process item in the form of a large-area multilayer body with layers of different physical properties is possible.
