A method for regulation of the angular position of hollow bodies in an installation for production of containers. The hollow bodies are moved by individual support members each of which is equipped with means for causing the hollow body to turn about its axis. The method includes a first step of measuring an angular offset of at least one particular hollow body relative to a reference angular position in a measurement zone. The method also includes a second step of compensating of the angular position of the subsequent hollow bodies in a compensation zone upstream of said measurement zone as a function of the angular offset measured for the at least one particular hollow body.

Method for angular orientation of hollow bodies in a plant for manufacturing containers

A process for angular indexing of a pre-form having a body and a neck. The process includes a step of marking the neck of the pre-form which consists of production of at least one reference point on the neck of the pre-form. The process also includes a step of a heating station taking charge of the pre-form, during which the pre-form is transported along a heating course by a support unit, known as a spinner, which makes it possible to turn the pre-form around its axis, and during which the body of the pre-form is heated. The marking step is carried out during the step of taking charge, when the pre-form, supported by a spinner, travels along the heating course.

Method for angular indexing of a preform

A method for producing a container from a blank, inside a forming unit having a mold and a movable insert controlled by a variable-flow solenoid valve, a control unit linked to the solenoid valve. The method comprises developing a boxing curve characterizing the successive positions of the insert; determining, based on a reference blowing curve, points of inflection; measuring, on the boxing curve, distances actually travelled by the insert between points in time, some of which correspond to these points of inflection; and comparing the values of the measured distances with nominal values. If there is a difference between a measured value and a nominal value, controlling, by the control unit, a modification in the flow rate setpoint of the solenoid valve for the next production cycle.

Disclosed is a method for manufacturing a container from a blank in a mold provided with a movable insert, wherein the method includes the following phases: pre-blowing; blow molding; boxing; and the following operations: measuring the prevailing pressure in the blank in real-time and storing the measurement in a memory; measuring the position of the insert in real-time and storing the measurement in a memory; detecting a time tindicating the actual start of the blowing phase and moment tindicating the actual start of movement of the insert and storing same in a memory; calculating T1=t&#x2212;t; comparing T1 with a predetermined non-zero reference T1, as long as T1 is different from T1, and delaying the start of the boxing phase.
