A method of conveying plastics material pre-forms includes the plastics material pre-forms supplied to a conveying device by a supply device. The conveying device has a first roller body and a second roller body. The plastics material pre-form is conveyed between these roller bodies. A portion of the plastics material pre-forms is supported by the two roller bodies. A further portion of the plastics material pre-forms passes through between the roller bodies. At least one first value characteristic of a state of occupation of the plastics material pre-forms is detected by a first measuring instrument. A second value characteristic is detected by a second measuring instrument downstream of the first measuring instrument in the conveying direction of the plastics material pre-forms. A setting variable of the supply device or the conveying device is controlled on the basis of the two values.

An apparatus for processing containers having a transport device which transports the containers to be processed along a predefined transport path has at least one processing device which is configured to process a container in a predefined manner, wherein the apparatus has a movement device, having at least one first guide cam and at least one guide roller which is configured to roll relative to the guide cam. The apparatus also has a detection device which is configured to detect at least one measurement value which is characteristic of a running property of the guide roller relative to the guide cam, and an evaluation device which is configured to evaluate this detected measurement value taking into account at least one further operating value characteristic of the operation of the apparatus.

Provided is a method for verifying holding members in a heating station equipped with a device for transporting the preforms. The device includes a plurality of movable supports circulating in a closed circuit and members for individually holding the preforms by their neck, where each of the holding members is borne by a movable support. The method includes setting the movable supports in movement to bring them successively into an acquisition zone, acquiring an image of each individual holding member in the acquisition zone, and automatically verifying the presence of a holding member on each of the images taken.

A preform is heated, the heated preform is sealed in a sealing apparatus including a neck portion mold, a trunk portion mold and a bottom portion mold at a predetermined temperature range, and the heated preform sealed in the molds is blow-molded into a bottle. Any molded bottle is removed if the mold surface temperature of the neck portion mold, the trunk portion mold and the bottom portion mold are outside of the predetermined temperature range. A sterilizer is blasted to any molded bottle not removed when the mold surface temperature of all of the molds is in the predetermined temperature range.

An operation abnormality detection method for detecting an operation abnormality in a molding device having a movable part includes: acquiring a prescribed measured value relating to operation of the movable part and calculating, as statistical information, an average value of prescribed information values based on the prescribed measured values: calculating a first threshold and a second threshold; acquiring a current measured value and comparing a current information value based on the current measured value with the greater of the first threshold and the second threshold; and issuing a warning if the current information value at least exceeds the greater of the first threshold and the second threshold.

Provided is a thermal conditioning method of preforms. The method includes heating each preform by transport along a heating path exposed to heating radiation with a determined production rate; transporting the preforms (in line along a diffusion path; transforming the preforms in forming units at the determined production rate. The diffusion path includes a final buffer section along which the preforms travel for an adjustable duration.

A manufacturing apparatus and method for a resin container. The apparatus includes at least: a heating unit configured to heat a preform; a blow molding part configured to mold a plurality of the preforms into a container; and a conveyance member configured to convey the plurality of preforms that has been heated to the blow molding part. The conveyance member includes: a plurality of holding arms each configured to hold one of the plurality of preforms; a connecting member configured to connect together the plurality of holding arms at equal intervals; and a pitch changing mechanism configured to change a pitch between the plurality of holding arms, and the pitch changing mechanism includes a stopper mechanism configured to position the plurality of holding arms at a predetermined wide pitch when an interval of the holding arms is changed from a narrow pitch to the predetermined wide pitch.

A container treatment system includes a production machine for preforms, a blow molding machine and at least one heat exchange device. The production machine and the blow molding machine are interlocked with one another, and the at least one heat exchange device is configured for heat exchange between the production machine and at least one component of the container treatment system.

An installation 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 installation includes a means for measuring, in a first step an angular offset of at least one particular hollow body relative to a reference angular position in a particular measurement zone. The installation also includes a means for compensating, in a second step the angular position of the subsequent hollow bodies in a compensation zone upstream of said measurement zone during which the angular orientation of the subsequent hollow bodies is modified by an updated compensation angle that is a function of the angular offset measured for the at least one particular hollow body.
