Abstract: Method for producing a vessel (1) by stretch blow-moulding in a mould (11) from a preform (3) made of plastic material, comprising the operations consisting in heating the preform (3) to a predetermined heating temperature (T); introducing the preform (3) in the mould (11); stretching the preform (3) by means of a rod (16) displaced at a predetermined stretching speed (VE); 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 (PP) and a pre-blowing flow rate (DP); measuring the pressure (P) inside the preform (3); detecting a pressure peak; memorising the moment (tB) at which this pressure peak occurs as well as the corresponding pressure (PB) inside the preform (3); comparing the moment (tB) and the pressure (PB) of the peak detected with, respectively, a predetermined moment and pressure for a theoretical pressure peak; if

Abstract: The invention relates to a method for producing a vessel (2) by blowing in a mould (11) from a preform (3) made of a plastic material, comprising the following steps: placing 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 (PP); measuring the pressure (P) inside the preform (3); at a predetermined moment, called blowing cue (tS) and following the pre-blowing cue (tP), controlling the opening of an electrovalve (26) for establishing a communication between the inside of the preform (3) and a source (24) of gas at a predetermined blowing pressure (PS) higher than the pre-blowing pressure (PP); memorising the variations of the pressure (P) inside the preform (3) at least during the interval between the pre-blowing cue (tP) and the blowing cue (tS); detecting in said interval a so-called expan

Abstract: The invention relates to a device (10) for loading containers (12), which are provided with a neck (20), on an transporting element (14) comprising a member (28) for individually grasping the container (12) by the neck thereof (20), wherein said grasping member (28) is used for catching or releasing the neck (20) of a preform (12) by the vertical slide of said preform (12) with respect to said grasping member (28) during an operation for catching or releasing it, the loading device (10) comprises means (42, 68) for selectively ejecting the container (12) from the transporting element (14) during the releasing operation and the inventive device is characterised in that said means for ejecting the container (12) is provided with container (12) reception means (42) which are used for catching the container (12) prior to the releasing operation and are mounted in a horizontally movable manner in such a way that the trajectory of the receiving means (42) are vertically superimposed and synchronised with the trajec

Abstract: 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).
