FIELD: sheet forming, namely manufacture of laminate blanks for drawing parts, mainly with damping properties in machine engineering. SUBSTANCE: method comprises steps of making shaped blank and joining its layers at blanking process due to formation of vertical burrs on separate portions of blank perimeter. Layers of blank in the form of two sheets or strips with synthetic film placed between them are loaded to blanking die set. Portions with vertical burr are arranged in zones of minimum displacement of blank flange at process of successive drawing. Length value of portion with vertical burr is selected equal to 5-7 thickness values of laminate blank. Said vertical burr is formed due to provision of increased gap between die and punch. EFFECT: enhanced efficiency. 3 cl, 3 dwg
