<p>The machine has a stretching rod (4) with a drive unit (A) comprising an electric servo motor (M) i.e. rotary motor, coupled for transmitting linear movements for electrically stretching a preform. The stretching rod is changed in a defined axial direction, and a stretching rod quick change device (W) is provided in a blow molding station (S) that is transferred between a centered operating position and a change position. The drive unit with the motor is mounted at a bearing support (1) of the blow molding station. The motor is coupled with the stretching rod to a stretching slide (6).</p> |
