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.

[ What is claimed is:] [1.] Transfer device for transfer of workpieces between press stations along a given transfer direction, comprisingsupporting and guiding devices which extend essentially along the transfer direction and which carry therebetween cross transverses equipped with gripping devices arranged to be engaged with and disengaged from the workpieces, anddriving devices configured to be operated independently of the supporting and guiding devices and configured to act upon the gripping devices for swivelling the gripping devices about an axis of rotation transverse to the transfer direction,wherein at least one of the cross traverses carries a bearing device on which the associated gripping device is operatively disposed to be swivelled about the axis of rotation, and is configured to carry the associated driving device for swivelling the gripping device such that the gripping device and its associated bearing device, can be installed or replaced completely independently of the supporting and guiding devices.
