摘要： Plate packs are produced from a sheet-like starting product (1), which is cut to form plates, which are stacked to form a plate pack. The plates within the plate stack are joined to one another by a bonding agent. The bonding agent used is a cyanoacrylate adhesive with a high temperature stability rating. It is applied to a wetting layer (14) for the adhesive. The wetting layer (14) is formulated to a pH in a region >7. The cyanoacrylate adhesive with a high temperature stability rating is able to spread on the wetting layer (14) such that effective wetting takes place, thus achieving quick and secure joining of the plates to one another.

摘要： In order to produce a clutch pack (3), clutch plates are cut from an electrical steel strip or sheet, arranged on top of one another to form the clutch pack (3) and connected to one another within the clutch pack (3). The material of the clutch plates is locally plasticised in the edge region via the generation of frictional heat by means of at least one tool (9'), in such a way that the material of at least adjacent clutch plates is mixed with the tool (9') such that, after the plasticised material has cooled, these clutch plates are integrally connected to one another. The device used for this purpose has at least one punch press and/or at least one receiving means for one or more clutch packs (3). In addition, the device has at least one welding tool that is rotatably driven about its axis and can be moved in a transverse direction to its rotational axis.
