An apparatus for producing plastic containers includes: a forming machine for producing plastic preforms; a blow-molding machine for blowing the preforms to obtain containers, provided with a blow-molding carousel having a plurality of blow-molding molds that expand the preforms to obtain the containers; a thermal conditioning station interposed between the forming machine and the blow-molding machine; a storage station, configured for receiving and containing preforms; a supplying system for feeding the thermal conditioning station with preforms contained in the storage station.

Apparatus and method for producing plastic containers

An apparatus for producing plastic containers includes: a forming machine for producing plastic preforms; a blow-moulding machine for blowing the preforms to obtain containers, provided with a blow-moulding carousel having a plurality of blow-moulding moulds that expand the preforms to obtain the containers; a thermal conditioning station interposed between the forming machine and the blow-moulding machine; a storage station, configured for receiving and containing preforms; a supplying system for feeding the thermal conditioning station with preforms contained in the storage station.

An apparatus includes a first operating machine arranged for processing objects, a second operating machine positioned downstream of the first operating machine and arranged for further processing the objects, an accumulating arrangement interposed between the first operating machine and the second operating machine and arranged for receiving the objects, and a command and control arrangement arranged for detecting a parameter indicating the quantity of the objects contained in the accumulating arrangement and regulating the operation of the second operating machine on the basis of the parameter. A method includes dispensing synthetic plastics in a pasty state, compression-molding the plastics to obtain a perform, blowing the perform to obtain a container, and filling the container with a product. Each step maintains its own regulated temperature so that the dispensing temperature is greater than the blowing temperature and the blowing temperature is greater than the filling temperature.

Method and apparatuses

A device for transferring objects, in particular parisons () or bottles (), has a carousel () able to rotate about a predetermined axis (X), an object () pick up element (), a supporting arm () for the pick up element () connected to the carousel (), the pick up element () having at least three degrees of freedom relative to the carousel (), a cam () for guiding the arm () and the pick up element (), having a predetermined number of tracks (), for moving the pick up element () along a predetermined path (P); the cam () has a fixed portion () and at least one removable portion () connected to the fixed portion (), the removable portion () having a predetermined profile and there being the possibility of substituting it with other removable portions having a different profile to the portion ().

Transfer device

Filling valve () for the aseptic filling of alimentary liquids characterized by the fact that the product stream flowing from the valve, in the area near by the filling mouth of the container underneath, is isolated from the atmosphere through a coaxial flow of sterile and/or inert gas () fed by an auxiliary circuit () surrounding the outlet conduit of the flowing product.

Filling valve for the aseptic filling of alimentary liquids

Improvements to isobaric aseptic filling machines are related to processing fluids that are not contained in a rotating tank but in a fixed tank. Such improvements also include a number of coil tubes generating high flow resistance during the filling phase of the process fluid.

Filling machine

Improvements to filling valves of bottling plants in which the interruption of the processing fluids' flow happens automatically when the level of the liquid inside the filled bottle reaches the lower edge of the vent tube and the air trapped in the filling valve prevents the coming out of the liquid from the tank even if the external membrane ( ) is still in the open position.
