Abstract

A transfer device for press systems has cross traverses with at least one suction unit swivellably held thereon. The suction unit has an electric drive for coordinating the swivel movement with the transfer curve (horizontal and vertical movement) to be travelled. As may be required, two or more suction units can be independently swivellable on a cross traverse. A retrofitting and retooling of existing cross traverses can be carried out by the replacement of non-swivellable suction units used so far by swivellable suction units. Other changes on the mechanical structure of the transfer device are not required.
