Abstract

A first sleeve and a second sleeve are put onto the shaft at a predetermined axial distance apart and are pressed radially. The shaft is encapsulated between the first and the second sleeve with a thermoplastic in such a way that a vane body, which has at least one aperture, is formed. The vane body is encapsulated with a sealing compound in such a way that a sealing lip is formed on the vane body at the margins.
