摘要：
Method for producing a vessel (2) by blowing in a mould (11) from a preform (3) made of plastic material, comprising the operations consisting in: introducing the preform (3) into the mould; at a predetermined moment, called pre-blowing cue (tP), controlling the opening of an electrovalve (22) for establishing a communication between the inside of the preform (3) and a source (20) of gas at a predetermined pre-blowing pressure; measuring the pressure (P) inside the preform (3); detecting the so-called real moment (tA), of the beginning of the pre-blowing, at which the (P) in the preform (3) starts to increase; comparing this moment (tA) with a theoretical pre-blowing beginning moment; if the real moment (tA) of the beginning of the pre-blowing follows the theoretical pre-blowing beginning moment, advance the pre-blowing cue (tP); if the real moment (tA) of the beginning of the pre-blowing precedes the theoretical pre-blowing beginning moment, delay the pre-blowing cue (tP).
摘要（中）：
通过从由塑料材料制成的预成型体（3）吹入模具（11）来制造容器（2）的方法，包括以下操作：将预成型件（3）引入模具中; 在预定时刻，称为预吹提示（tP），控制用于在预成型件（3）的内部和气体源（20）之间建立预定预吹气的电气阀（22）的开口 压力; 测量预成型件（3）内的压力（P）; 检测在预成型件（3）中的（P）开始增加的预吹开始的所谓的实际时刻（tA）; 将此时刻（tA）与理论预吹开始时刻进行比较; 如果预吹开始的实际时刻（tA）遵循理论预吹开始时刻，则提前预提示（tP）; 如果预吹开始的实际时刻（tA）先于理论预吹开始时刻，则延迟预吹提示（tP）。
