Method, tool and device for producing a stack of laminations and stack of laminations

摘要

The method involves partially and contactlessly applying adhesive (16) on an upper and/or lower side of a lamination (24) by using an integrated system based on a piezo-electric technique, where the application of the adhesive is interrupted by a signal. A base material (1) e.g. continuous strips, is supplied in the form of a coil or individual sheet metals. Materials of different quality, thickness, characteristics and coating are added to the laminations. Independent claims are also included for the following: (1) a tool for manufacturing lamella packages (2) a device for manufacturing lamella packages (3) a lamella package, which is manufactured with the procedure.
