Claim:
A machine for the production of hollow glassware articles, by the blow-and-blow process, press-and-blow wide mouth or narrow neck process, press-and-blow paste mold process and direct press process in a glassware forming machine including single or multiple machine sections, each section having single or multiple cavities, comprising: a) a parison forming station including a blank mold apparatus, an inverting apparatus including at least one open-able horizontal holding arm, and at least one transferable and open-able neck ring mold, per cavity, removably held by the horizontal holding arm of the inverting apparatus, to be initially placed under the blank mold apparatus to form a parison which is held by said transferable and open-able neck ring mold once formed and transferred by the inverting apparatus from this parison forming station to an intermediate station at an upright orientation; b) an intermediate station including a transference apparatus to transfer the parison held by the transferable and open-able neck ring mold from the inverting apparatus at the intermediate station to a blow forming station, said transference apparatus comprising holding arms normally closed, gripping fingers coupled to the holding arms for internally gripping the transferable and open-able neck ring mold at said intermediate station, and a two-positions opening mechanism which, at a first position, partially opens the gripping fingers to grip the transferable and open-able neck ring mold gripping the parison, while simultaneously the inverting apparatus release them to be retained by the gripping fingers of this transference apparatus at said intermediate station and, at at the blow forming station, the gripping fingers are additionally opened, opening the transferable and open-able neck ring mold releasing the parison at said blow forming station, but still keeping the transferable and open-able neck ring mold held by the gripping fingers of the transference apparatus; and in an inverse way, said gripping fingers of the transference apparatus turn the empty transferable and open-able neck ring mold closed from said blow forming station, back to the intermediate station, and are further closed, releasing the empty transferable and open-able neck ring mold at the open-able horizontal holding arm of the inverting apparatus to be held thereby for a following forming cycle; and a blow forming station comprising a blow mold apparatus, to receive the parison from the transference apparatus, and form a finished article, and a take out apparatus, to transfer the finished article from the blow mold apparatus to a dead plate or to a carrier conveyor.
