The invention relates to a method for connecting sheet metal parts (4) to form a laminated core (11), wherein sheet metal parts (4) are separated, in particular punched, from a sheet metal strip (2) that has, at least in some areas, a layer having curable polymer adhesive (12), and the sheet metal parts (4) are preliminarily connected to form a laminated core (11), the preliminary connection comprising plasticizing the adhesive (12) at least in some areas and joining the sheet metal parts (4) in order to connect the sheet metal parts by means of the plasticized adhesive (12) of at least one of the sheet metal parts (4), and in a subsequent step the laminated core (11) having preliminarily connected sheet metal parts (4) is subjected to a curing of the adhesive (12). In order to create an advantageous connection between the sheet metal parts, the plasticizing of the adhesive (12) comprises the introduction of a softener (16), in particular H2O.
Method for connecting sheet-metal parts (4) to form a laminated core (11), comprising removing sheet-metal parts (4) from a sheet-metal strip (2) having a layer that contains a thermally curable polymer adhesive (12), at least in certain regions, and these sheet-metal parts (4) are connected to form a laminated core (11), which preliminary connection comprises plastification of the adhesive (12), at least in certain regions, and
