Invention patent: "method to inspect the material distribution of a sequence of blow molded containers in a production process contu00ecnuo; the method to control the distribution ofThe material of a sequence of containers molded by stretching and blow in a production process contu00ecnuo; control system for.Control the material distribution for a sequence of containers molded by stretching and blow in a production process contu00ecnuo ".A method to inspect the material distribution of a sequ00b3u00eancia containers or other articles molded by drawing and blowing in a continuous production process.By providing parisons injection molded, each parison possessing at least one indicator, typically two or more indicators.To detect the distribution of material in a predetermined position along the axial extent of the parison.Each of the parisons is subjected to a heating stage in the continuous production process, generally by exposure to heating by infrared radiation.Each parison heated is next subjected to a blow molding process, which can be a stretch blow moulding process.So that each indicator of material distribution is changed to a corresponding position along the axial extent of the article molded by the blow.A detector is positioned to detect the location of each indicator on each article molded by blowing from a mold in the production process.A computation is performed for determining, for each article molded by blow molding, a result or distribution pattern of material based on the detected locations of each indicator.Such information about the distribution of material are then compared to a profile required for the specific design of the container and any discrepancy beyond certain values pre adjustedTolerance is used to reject the item out of the tolerance of the production line and to change a phase of the production process as the configuration of the heating by infrared radiation.
