A method for blow-moulding containers, and a machine for said method. A method for producing thermoplastic containers by stretch-blow moulding which involves selecting at least one characteristic point of the pressure (Prt) in the container, for each selected point, defining a triggering criterion (∆P, P'), and a pre-defined value of the criterion, during a production and data acquisition cycle, measuring the pressure (Prt) in the container. For each selected point, the method involves defining a setpoint time for triggering, in the subsequent production cycle, the switch to the sub-phase after the characteristic point, such that: if the actual value of the criterion is less than or equal to the pre-defined value, the setpoint time is the time at which the criterion has assumed a value equal to the predefined value, and if the actual value of the criterion is strictly higher than the pre-defined value, the setpoint time is after the actual time and is defined such that, at that time, the criterion assumes a value close to or coinciding with the pre-defined value. |
