A method of starting a machine comprising a plurality of modules, each module having a standard run-up time until optimum operating conditions are obtained. The method includes acquiring for each module of an initial state at a time Tand a run-up time to reach the optimum operating conditions from the time T. The method also includes identifying a slow module having the longest run-up time and determining a time Tof optimum operation, following run-up, at which said slow module has its optimum operating conditions. For each module () other than the slow module (), the method establishes a starting or run-up time set point for which its optimum operating conditions are reached only at the time Tor in the immediate vicinity of the time T

Start-up method for multi-module machine

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.

A method for regulating a facility for processing a series of containers includes an operating phase during which a first machine for processing containers that is equipped with a number of first stations is driven in rotation, and a second machine for processing containers that is equipped with a number of second stations is driven in rotation. The facility has a transfer point from the first to the second processing machine. The operating phase includes a synchronized and paired operating step in which the synchronized rotation of the first and second machines is accompanied by a repetitive series of pairing partners at the transfer point, each pairing partner including a first station arriving at the transfer point coincidentally with a second station, enabling transfer of a container from the first station of the pairing partner to the second station of the pairing partner.

Disclosed is a maintenance method for an installation for production of containers from blanks made of plastic material, which includes: a blow-molding machine including a rotating carousel and a plurality of forming stations, each including a mold; a primary power unit connected to the carousel; a transfer device suitable for inserting a blank into a mold or for withdrawing a container therefrom; and a secondary power unit connected to the transfer device. The method includes the detection of a misalignment of the transfer device with the carousel, and, therefore, operations for desynchronization of the power units, for realigning and then for resynchronization of the transfer device and of the carousel.

Disclosed is a method for adjusting the travel of a stretching sliding rod that belongs to a device for forming hollow bodies made of thermoplastic material by stretch blow molding, with the stretching rod being controlled cyclically in terms of sliding from a rest position to an adjustable stretching end position by stretching the malleable wall of a hollow body, before returning to its rest position to begin a subsequent stretching cycle of another hollow body, with the method including a control step that consists in detecting whether an axial force that opposes the sliding of the stretching rod at the end of travel is above a determined upper boundary. The stretching end position is adjusted automatically by being subjected to the axial force that is detected during the control step.

A method of manufacturing a container from a blank in a stretch blowing assembly equipped with a mold provided with a wall and a mold bottom axially movable between an extended position and a retracted position and a stretch unit having a rod axially movable with respect to the wall and a device for controlling the movement of the rod. The method involves a stretch blowing phase; a boxing phase during which the mold bottom, initially in the extended position, is moved towards its retracted position, the boxing phase having a retraction operation including controlling a movement of the rod in synchronization with the movement of the mold bottom, or releasing the rod to allow the free axial movement thereof.

Method for the stretch-blowing of a container, comprising a retraction of the stretch rod during a boxing operation

Method of manufacturing a container from a blank of plastic material, within a mold provided with a wall defining a cavity with the impression of the container, and a mold bottom that is movable with respect to the wall between a retracted position and a deployed position in which it extends protruding into the interior of the cavity in order to form a hollow recess in the container. The method includes inserting the blank into the mold; a pre-blowing operation including injecting a fluid under pressure into the blank, at a pre-blowing pressure; a blowing operation including injecting a fluid under pressure into the blank at a blowing pressure that is greater than the pre-blowing pressure; and a boxing operation, initiated prior to the blowing operation, and including moving the movable mold bottom from its retracted position to its deployed position.

Method for manufacturing containers, including an anticipated boxing operation

Conveyor for transporting articles such as a chain conveyor that can be changed between a stretched configuration and a compact configuration, the chain being formed from a plurality of articulated links. Each link includes a trolley provided with lateral guide mechanism cooperating with a track defining a predetermined trajectory, a support carrying a nozzle for the releasable attachment of an article, the support mounted rotatably with respect to the trolley between a straight position corresponding to the deployed configuration of the chain, and an oblique position, corresponding to the compact position of the chain and in which the support is inclined with respect to the straight position; and an actuator coupled to the support, capable of driving the support in rotation from its straight position to its oblique position, and reciprocally.
