LAMINATED CORE AND METHOD FOR CONNECTING SHEET METAL PARTS TO FORM A LAMINATED CORE

摘要

A laminated core and a method for connecting sheet metal parts to form a laminated core, wherein sheet metal parts are separated from a sheet metal strip having, at least in some regions, a layer of curable polymer adhesive, and the sheet metal parts with adhesive-coated sides facing one another are provided above one another and are bonded under pressure to form a laminated core. In order to create advantageous method conditions, according to the invention a mixture comprising water and a thermoplastic and/or cross-linkable adhesion promoter is provided on at least one of the adhesive layers facing one another during bonding of the sheet metal parts.
