The subject matter of the invention is a pressing module for the press-forming and curing of impregnated conductor bars for large electrical machines, such as for example hydro generators, which is distinguished by an improved closing system for applying the pressing pressure, and a pressing apparatus equipped therewith, the handling of which involves significantly reduced work. A pressing module (1) according to the invention comprises a pressing vat (2) for applying a horizontal pressing force and a pressing yoke (3) for applying a vertical pressing force. The closing units (6) and (7) for applying the horizontal and vertical pressing forces thereby comprise a housing (20), which receives, slidingly mounted therein, a pressing piston (21), which is in operative connection with an axially fixed, rotatable threaded bolt (27) in such a way that a turning movement of the threaded bolt (27) brings about an axial movement of the pressing piston (21). An axial bearing (3), supported on a spring assembly (35), provides a flexible mounting of the pressing piston (21). The threaded bolt (27) protrudes on the rear side of the housing (20) and is provided there with a contour (36) for receiving a tool, for example a pneumatic screwdriver.
