A system for carrying out a method for producing stacks of laminations, in which at least one adhesive is applied onto annular laminations with at least one application device and laminations are stacked into a stack of laminations, the method comprising: rotating each of the laminations (5, 6) about its axis (17) in an application area of the application device and/or moving the application device about the axis (17) of the lamination (5, 6) in order to apply the adhesive; wherein the system comprises:
at least one punching tool configured to punch the laminations out of a sheet metal material;
a station (4a, 8, 9) comprising the application device comprising at least one application nozzle (16) configured to apply the at least one adhesive onto the laminations (5, 6), wherein the application device further comprises at least one cleaning nozzle (14) arranged upstream of the at least one application nozzle (16) and configured to clean the laminations (5, 6);
wherein the station is arranged downstream of the punching tool (4).
