Lamination stack made by segments

摘要

The stack has two segments (2) with a side edge (11) providing a groove (12) and on an opposite edge (9) a corresponding projection (10) is provided. The two segments are connected to a construction unit. The projection and the groove (12) are separated by a distance in such a manner that by inserting the projection into the groove plastic portion is deformed, so that the projection intervenes in the extended section of the groove.
