The method involves loading a prestretcher (12) by a prestretcher drive device (1), and guiding the prestretcher into an associated downholder unit in a sealed manner. The prestretcher is moved and maintained from an initial position (OT) to a lower end position (UT) and back into the initial position after a molding process, without application of forces against developing backing force to the drive device, where the forces against the developing backing force are developed by form air on the prestretcher. |
