摘要： Method for manufacturing plastic bottles, including the step in which respective preforms are removed from the respective moulds, and the step in which said preforms are transferred into temperature conditioning stations for a predetermined period of time, during which said preforms are caused to undergo an asymmetrical heat treatment that is effective in heating in a different manner a preform sector having an angular spread of a definite value that is anyway not less than 180 the method includes the step in which said surface sector of the preform is heated up with the help of heating means (2b, 2c) that are partially arranged in a crown-like manner around the respective preform. The blow-moulding process comprises the sub-steps in which: the stretching rod is inserted into the preform up to the point in which it almost comes into contact with the bottom thereof; a stretching counter-rod is approached from the outside of the preform up to the point in which it almost comes into contact with the bottom of the preform; the preform undergoes blow-moulding while, at the same time, said stretching rod moves further forward into the preform and, by in this way pressing against the bottom of the preform, pushes the stretching counter-rod in a direction of ejection from the blow-moulding cavity.

摘要： Apparatus for continuously transferring orderly sequences of preforms, comprising a closed-loop conveyor belt that constitutes guiding means for a closed-loop moving conveyor chain, which is adapted to be driven into a continuous motion and comprises a plurality of support and forward carrying elements (3, 3a) capable of carrying respective preforms by means of appropriate pick-up plugs, a loading station and an unloading station. The loading and unloading stations are arranged so as to enable the preforms to be loaded onto the pick-up plugs, and released therefrom, in a vertical position with their neck portion turned upwards. The support and forward carrying elements are in turn rotated so that, when they move into the conditioning station, the respective preforms are positioned vertically with their neck portion turned downwards. The apparatus further comprises two horizontal stretches that follow a conditioning station and precede the preform loading station, respectively. Said two horizontal stretches are capable of being lengthened and/or shortened so as to be given a predetermined length in accordance to the time specifically assigned to the particular types of preforms for covering the stretch from the conditioning station to the unloading station, wherein the overall length of said conveyor belt and the related chain must however remain constant.

摘要： Single-stage method for the production of resin preforms, comprising the phases of: filling a plurality of multiple-cavity moulds, holding and cooling down said resin inside said moulds, removing the moulded preforms from said moulds, subjecting said preforms to a subsequent temperature conditioning phase, transferring said preforms to appropriate blow-moulding tools and clamping them therein for the final blow moulding operation, and wherein each one of said multiple-cavity moulds comprises a plurality of cavities defined in several (A-N) distinct clusters belonging to the same mould, said cavities being cooled down by means of a forced circulation of cooling medium through appropriate cooling conduits, wherein the cavities belonging to a same cluster are cooled in a distinct and differentiated manner with respect to the cavities belonging to the other clusters of cavities provided in the same mould. Said clusters of preforms are subjected individually to said temperature conditioning phase in an orderly sequence, so as to cause said clusters of preforms to queue up for reaching said temperature conditioning phase after a differentiated time.

摘要： Method for pre-treating a mass of fiber-grade PET (polyethylene terephthalate) resin in granular form, wherein said pre-treatment method is carried out before a drying treatment and includes keeping said mass of PET resin in a stream of air heated to a temperature of substantially 170°C through a period of not less than 1.1 hours in such a manner that substantially the entire mass of resin is exposed to and affected by said stream of hot air and is stirred continuously.
In a preferred manner, said air is then removed from said mass of material and exhausted in such a manner that it is prevented from mixing up with the air taken in to form the stream of air being again blown into said mass of material. The purpose of the method is to convert fiber-grade PET into a polymer having properties that are very close to the ones of bottle-grade PET and, in particular, having an acetaldehyde content that is lowered from approx. 60 ppm to approx. 3 ppm, as well as an ultimate crystallinity of approx. 35% over the whole mass of treated material.

摘要： Apparatus for blow moulding hollow plastic bodies from plastic preforms, or parisons, which is adapted to detect bursts occurring in plastic bottles. To this purpose, the apparatus itself comprises a differential pressure transducer arrangement (10, 11), a low-pressure gas supply source (103) along with a related first supply channel (101), a high-pressure gas supply source along with a related second supply channel (105). The differential pressure transducer arrangement is made up by one or more tubes (3, 4) arranged crosswise in the second supply channel; these tubes contain respective separate chambers opening (5, 6) into the interior of said second supply channel (Pitot tubes). Two sensors (7, 8) adapted to detect respective pressures are connected in a distinct manner to said respective chambers. Any possible pressure variation at pre-determined moments during the blow-moulding cycle is processed and compared, and the result is an indication of whether a serious irregularity, such as a burst or a silent gas leakage, took place during the blow-moulding process of a given bottle.
