Abstract: A method for manufacturing a rotor for an electrical machine having a rotor support and a laminated core includes positioning the laminated core on a first component of the rotor support, where the laminated core at least partially radially encloses the first component relative to an axis of rotation of the electrical machine. The method further includes welding an axial end face of the first component of the rotor support with a second component of the rotor support to form the rotor support by friction welding, where the laminated core is fixed on the rotor support by fastening elements which respectively enclose the laminated core on both sides of the laminated core in an axial direction. At least one of the fastening elements is formed by a weld bead.

Abstract: A description is given of a document with a hologram as a security feature, in particular an identity card (12), consisting of a polycarbonate card body (10), which has a volume hologram label (2, 9) embedded therein. A description is additionally given of a method for producing the document, in which volume hologram labels (2) arranged on a carrier sheet are brought into contact with adhesive regions (4) on a thermoplastic sheet (5.1), the adhesive surfaces are cured and the carrier sheet is then removed. A second plastics sheet (5.2) is then adhesively bonded onto the first plastics sheet (5.1), bearing the hologram labels, using a second adhesive (7) in the region of the hologram labels (2) to form a two-layered sheet composite (6) which, finally, is laminated, together with further thermoplastic sheets, in a card-lamination press, under the action of pressure and temperature, to give a card body (10), individual identity cards (12) being punched out.
