Blow moulding machine with controlled movement of the stretch rod and blow moulding nozzle

An apparatus (1) for the shaping of plastics material pre-forms (10) into plastics material containers (20) with a movable carrier (2) on which at least one shaping station (4) for shaping the plastics material pre-forms (10) into the plastics material containers (20) is arranged, wherein the shaping station has a blow moulding device (6) which forms a cavity inside which the plastics material pre-forms (10) are capable of being shaped into the plastics material containers (20), and wherein the shaping station additionally has a stressing device (12) 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 (14) 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 (24) which moves the rod-like body (14) with respect to the plastics material pre-form, wherein a coupling device (30) is provided which couples a movement of the rod-like body (14) with respect to the plastics material pre-form to a movement of the stressing device (12) with respect to the plastics material pre-form (10)—in particular in a mechanical manner—at least for a time, and the apparatus has an influencing device (40) which influences a supply movement of the stressing device (12) towards the plastics material pre-form at least locally and/or at least for a time.
