With lightweight construction in mind, aluminium as well as highstrength magnetic and nonmagnetic steels have a high development potential. For the automation process in blank stacking and destacking systems in the press shops, the overhead and vertical transportation of steel and aluminium blanks on conveyor belts is necessary. The belt conveyor system according to the principle of centre suction consists of a pair of toothed belts and fixed centrally positioned suction nozzles. Depending on the requirements, vacuum is created using the venturi principle or with high-performance fans.
