Abstract: In a glassware molding machine, the half-molds of a mold are moved between an open position and a closed position and cooled by an actuating and cooling assembly having a fixed supporting structure and, for each half-mold, a respective supporting and actuating arm fitted to the relative half-mold and hinged to the fixed supporting structure to rotate about a fixed hinge axis; each supporting arm internally defining a chamber communicating with a ring of cooling conduits formed through the half-molds, and the chamber having an inlet formed through an outer lateral wall of the supporting arm to receive cooling air from a compressed-air tank of the machine.

Abstract: A push device, for transferring glass articles from an intermediate supporting plate to an unloading conveyor, has at least one seat bounded by two flat supporting surfaces converging with each other and forming between them an angle of over 90°, and by at least one further supporting surface adjustable in position with respect to at least one of the two flat supporting surfaces; the article being retained close to a convergence area of the two flat supporting surfaces by a circuit for feeding compressed air between the two flat supporting surfaces.

Abstract: In a transfer unit for transferring glass articles from a supporting surface to a carry-off conveyor, a pickup member, for engaging the articles for transfer, is moved between a pickup position and a release position by an actuating device having a single articulated arm, and two electric motors activated independently to move the pickup member with respect to the articulated arm, and to move different portions of the articulated arm with respect to one another.

Abstract: A method and device for transferring glass articles from an intermediate supporting plate to an unloading conveyor, wherein the article to be transferred is positioned and retained inside a seat on a movable member by feeding compressed air through the movable member; the compressed air being fed in close to an edge of a dihedron formed by two plates of the movable member, and being oriented upwards towards the article to divide the incoming compressed air into two lateral streams laterally and at least partly surrounding the article, and into an upward-directed rear stream.
