The efficiency of regenerative heat exchangers with heat storage nozzles made of rolled corrugated tapes depends on the type of their corrugation profile. The most effective form is a triangular one with sharp peaks and troughs. It is technically advisable to get corrugations of a given shape by rolling between two rollers. Determining the required contact load and forces is one of the main tasks when rolling corrugated belts. Insufficient load leads to incomplete formation of the profile, and excessive load leads to warping of the belt. The article presents the results of an experimental study aimed at determining the required load when rolling a corrugated heat exchanger belt for wind tunnels. Experiments and force measurements are carried out on a standard milling machine with a spring dynamometer. The results of the experiment are applied to stainless steel strips with a thickness of 0,3 to 0,4 mm and triangular fluting
