Apparatus and methods for loading parts in a press wherein a conveyor transports the parts in a forward movement direction towards the press. An optical measuring device determines the real position of the parts on the conveyor. At least two transfer devices are configured to grab the parts off the conveyor and place them directly on a first surface of the press. A control unit is configured to receive the real position of the parts determined by the optical measuring device, and to compare the real position with a theoretical loading position of the parts on the first surface of the press. The control unit determines a deviation between the real and theoretical loading positions and uses the calculated deviation to command the transfer devices to correct the deviation and to place the parts on the first surface of the press in the theoretical position.

Method and installation for cutting a sheet metal format
Disclosed is a method and installation for cutting a sheet metal format with a predetermined contour from a sheet metal strip supplied in a forward movement direction. The sheet metal is cut by means of a cutting head. A distance is measured from a point of an edge of the sheet metal strip aligned with the cutting head in a direction perpendicular to the forward movement direction is measured with respect to a reference point and in perpendicular direction. A corrected cutting path is calculated from a predetermined cutting path depending on the measured distance, and the cutting head is caused to follow the corrected cutting path.
