Abstract

An apparatus () for the shaping of plastics material pre-forms () into plastics material containers () with a movable carrier () on which is arranged at least one shaping station (), wherein the shaping station has a blow molding device (), and wherein the shaping station additionally has a stressing device () which acts upon the plastics material pre-forms with a flowable medium for their expansion, wherein the shaping station additionally has a rod-like body () which is capable of being inserted into the plastics material pre-forms in order to stretch them in the longitudinal direction (L) thereof, wherein the shaping station has a drive device () which moves the rod-like body () with respect to the plastics material pre-form. According to the invention a coupling device () is provided which couples a movement of the rod-like body () with respect to the plastics material pre-form to a movement of the stressing device () with respect to the plastics material pre-form ()—in particular in a mechanical manner—at least for a time, and the apparatus has an influencing device () which influences a supply movement of the stressing device () towards the plastics material pre-form at least locally.
