Abstract
A method and a device for connecting sheet metal parts to form lamination stacks, wherein a sheet metal strip whose top and/or bottom surface has a hardenable polymer adhesive layer is transported continuously through an application device in which a fluid that contains an activator is applied to the adhesive layer, the applied fluid is dried, the sheet metal strip that is coated with the dried activator is continuously fed to a strip accumulator, the sheet metal strip from the strip accumulator is fed to a cyclically operating cutting device in which sheet metal parts are cut from the sheet metal strip and stacked on one another, and the cut and stacked sheet metal parts are connected to one another to form lamination stacks by means of the adhesive layers that are coated with the activator. The invention also relates to the lamination stacks produced according to the method.
