Abstract
The invention relates to a method and a machine for the production of hollow glassware, such as bottles, jars, glasses and other glass items, by means of the following processes: blowing-blowing, pressing-blowing, paste mould pressing-blowing or direct pressing, in glassware-forming machines comprising multiple sections. The inventive method comprises the following steps: a first preform or parison is formed in an inverted orientation in a parison mould and a first transferable crown mould which is supported by an inversion apparatus comprising a first arm and a second, diametrically-opposed arm which can be rotated by 180 DEG in an indexed manner, each of said arms supporting a crown mould; the parison supported by the first crown mould is inverted by rotating the first arm by 180 DEG at a vertical orientation towards an intermediary station, thereby enabling the parison to be reheated and stretched in said station, while the second arm with the second crown mould is simultaneously positioned at a parison-forming station in order to perform another parison-forming cycle; the first crown mould supporting the first parison in a vertical orientation is transferred along a semi-circular trajectory from the intermediary station to a blow-moulding station by means of a longitudinal transfer apparatus; the first parison is removed in a blow mould and the first crown mould is returned to the first arm of the inversion apparatus at the intermediary station in order to be repositioned at the parison-forming station by rotating the first arm by an additional 180 DEG , thereby completing a 360 DEG rotation, while the second arm reaches the intermediary station in order to perform a transfer cycle; the first parison is blown in a blow mould in order to form a finished product; and the finished product in a vertical orientation is transferred along a semi-circular trajectory, once the blow mould is opened, by means of an emptier such that said finished product is positioned on a dead plate for cooling and transferred to a conveyor belt.
