Abstract
A method and machine for blow-moulding containers, the method involves selecting at least one characteristic point of the pressure in the container; for each selected point, defining a triggering criterion, and a pre-defined value thereof; during a production and data acquisition cycle, measuring the pressure in the container; for each selected point, 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 ≤ 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.
