Abstract (en)
[origin: WO2021047788A1] In order to provide a method by means of which stacks of metal sheets can be produced in a simple and efficient manner, it is proposed that the method comprise the following: Coating one or more metal sheets with a bonding substance; bonding a plurality of metal sheets to form a sheet-metal laminate by first activation of the bonding substance; splitting the sheet-metal laminate to produce a plurality of sheet-metal laminate units and/or separating a plurality of sheet-metal laminate units out of the sheet-metal laminate; and bonding the plurality of sheet-metal laminate units to form a stack of metal sheets by second activation of the bonding substance, wherein one or more parameters differ from one another in the first activation and the second activation.
