<p>#CMT# #/CMT# The method involves introducing a bolt blank in a mold, and controlling opening of a solenoid valve for communicating the blank with a gas source at a pre-set blowing pressure, during a pre-blowing signal (tp). The pressure inside the blank is measured, and a real instant (tA) of starting of preblowing is detected, where the pressure starts to increase. The instant is compared with a theoretical instant of starting of preblowing, and the signal is advanced if the real instant is later to the theoretical instant. The signal is delayed if the real instant is prior to the theoretical instant. #CMT# : #/CMT# Independent claims are also included for the following: (1) a machine for fabricating a container from a bolt blank, comprising a mold (2) a computer program product to be implemented on a container fabricating machine, comprising instructions for controlling opening and closing of solenoid valve. #CMT#USE : #/CMT# Method for manufacturing a container from bolt blank. #CMT#ADVANTAGE : #/CMT# The method manufactures the container with good quality in industrial production, while limiting scrapping of the container and increasing global production of container. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graphical representation of a curve illustrating variations of pressure in blank during pre-blowing operation. tA : Pre-blowing starting real instant tb : Development instant tc : Expansion end instant tp : Pre-blowing signal tS : Blowing signal.</p> |
