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.

Abstract: The invention relates to a fluid flow control assembly for a container blowing machine, comprising: a blow pin (1); a plurality of pipes for the circulation of a blowing fluid, which enable the blowing fluid to flow between at least one blowing fluid source, at least one fluid discharge outlet and the aforementioned blow pin (1); and valves which can control the flow of the blowing fluid inside the plurality of fluid circulation pipes. The invention is characterized in that the valves are all placed on the front of a body (3) housing the blow pin (1).

Abstract: Device for moulding thermoplastic containers by blow-moulding hot preforms, comprising a mould (1) and blow-moulding means (2) comprising a bell nozzle (8) which is axially displaceable between a raised position and a blow-moulding position in abutment against the mould; the driving means comprising mechanical means (12) with a cam follower roller (13)/cam (14) and pneumatic means (16) with a piston (18) integral with the upper end of the nozzle and sliding in a fixed enclosure (17), defining therein an upper chamber (19) connected to a source (24) of control fluid and a lower chamber (20) connected to this source and to the upper chamber via a solenoid valve (26); the upper face of the piston has a surface area which is greater than that of its lower face and that of the bell (9) of the nozzle.
