ABSTRACT:
In a procedure for feeding two limp workpiece sheets intended to be treated together and/or connected with each other and positioning them with respect to each other, it is provided to clamp them in a planar suspended position in clips of trolleys guided by rails. They are moved by the trolleys to scan their contours in a scanning station and to align them relative to each other in an alignment station. The alignment position of the workpiece sheets is fixed through a coupling device, which acts upon clip holders on the trolleys and can be moved together with them. This simultaneously connects the trolleys assigned to each other in pairs into a structure moving as a unit. The workpiece sheets are subsequently guided in their fixed alignment position to a treatment or processing station.
