Abstract

The invention relates to a method for the bonding (baking) of magnetic steel sheets provided with an adhesive insulating layer (baking coating) and punched in an automatic machine, the individual punched parts being placed on top of each other and being bonded (baked) together under the influence of heat and axial pressure. In order to provide a method and an apparatus, with which the time and energy expenditure can be substantially reduced, it is proposed that each individual punched part is heated to the reaction temperature of the baking coating during stacking and is then immediately pressed onto the previously stacked punched part, and that subsequently the stack having the desired height is cooled. <IMAGE>
