METHOD AND MACHINE FOR MAKING CONTAINERS COMPRISING AN INTERMEDIATE DEPRESSURISING OPERATION |
摘要 |
The invention relates to a method for making a vessel (2) by blowing in a mould (11) and from a preform (3) made of a plastic material, that comprises: the operation of inserting the preform (3) into the mould (11); a blowing operation that comprises pressurising the preform (3) by feeding therein a gas at a so-called blowing pressure; a scanning operation subsequent to the blowing operation that comprises partially pressurising the vessel (2) by feeding therein a gas at a so-called scanning pressure lower than the blowing pressure; the operation of at least partially depressurising the vessel down to a pressure value lower than the scanning pressure, wherein said depressurising operation is carried out after the blowing operation and before the scanning operation. |
