Method and a machine for the production of hollow glassware articles

Abstract

A method and a machine for the production of hollow glassware articles, by the blow-and-blow, press-and-blow, press-and-blow paste mold and direct-press processes in a glassware forming machine including single or multiple machine sections each having single or multiple-cavity, comprising: forming a parison in an inverted orientation, into a blank mold and a first transferable and open-able neck ring mold held by an inverting apparatus having a first and a second diametrically opposed arms, each arm holding a transferable and open-able neck ring mold; inverting the parison held by the first transferable and open-able neck ring mold, by rotating the first arm 180° to an upright orientation at an intermediate station, while the second arm with a second transferable and open-able neck ring mold is simultaneously placed at the parison forming station; transferring the first transferable and open-able neck ring mold holding the parison in an upright orientation, from the intermediate station, to a blow mold station, by a transference apparatus; releasing the first parison into a blow mold, and turning back the first transferable and open-able neck ring mold empty to the first arm of the inverting apparatus, at the intermediate station to be placed again at the parison forming station by rotating the first arm additional 180°, completing a 360° turn, while the second arm reaches to the intermediate station; blowing the parison into a blow mold to form a finished article; and transferring the finished article in an upright orientation, once the blow mold is opened, by a take out apparatus, to place it at a dead plate or at a carrying conveyor.

       182 . A guide-funnel apparatus for guiding a molten glass gob feed to a glassware article forming machine having single or multiple forming cavities, of the type including a blank mold forming station, an intermediate station, and a blow forming station, and a take out station, by the blow-and-blow process, press-and-blow wide mouth or narrow neck process, press-and-blow paste mold process and direct press, comprising:
 funnel-carrier means, supported and operated by an oscillating mechanism mounted on an apparatus support frame of the machine, comprising a funnel-carrier arm supported and operated by the oscillating mechanism, including an annular funnel protector holder to be retained by a clamp on the funnel-carrier arm, by which the funnel-carrier means are simultaneously oscillated and lowered from an upper retracted inactive position to a lower active position and, after a molten glass gob is fed, its is simultaneously lifted and oscillated to the retracted position, and a guide-funnel carried by the funnel-carrier arm, including a flange to mount the guide-funnel on the funnel-carrier arm to be retained into the funnel protector holder for guiding a glass gob into the blank mold; and   a rotolinear oscillating mechanism for simultaneously oscillating and lowering one of said guide-funnel arms with its guide-funnel, from an upper retracted inactive position to a lower active position, to guide a molten glass gob feed through it and, afterwards, its is simultaneously lifted and oscillated to the upper retracted position.
