The present invention relates to a roto-linear mechanism for a glassware forming machine adapted to be connected to a funnel-holding arm, a shutter arm, an arm for a blowing head or a similar mechanism, to simultaneously perform an axial and radial movement to each of such arms from a first position to form glass articles to a second position outside the forming process thereof.

The present invention relates to a support block with individual hollow sections, for a machine for forming glass objects, and to its manufacturing method. The support block comprises: a single-piece support body formed by a front wall, a rear wall and lateral walls, thus forming a hollow rectangular body; an intermediate wall and a plurality of cross walls located inside the internal periphery of the support body, in a grid arrangement, forming a first plurality of hollow sections aligned along the front wall and a second plurality of hollow sections aligned along the rear wall, each first hollow section and each second hollow section being aligned and disposed one behind the other; a support section for each first hollow section and each second hollow section, each support section being connected near to the bottom part of each of the walls forming each first hollow section and each second hollow section, to support the different mechanisms of the machine for forming glass objects; tubular cavities located in a vertical position for each plurality of cross walls, for inserting lubricating pipes or cables, the tubular cavities being formed between each of the cross walls located inside the periphery of the support body; and aligning means located in a bottom part of the support body, for aligning the support block with respect to a determined installation area.

An inverting mechanism of a glass forming machine includes: a supporting structure; a shaft horizontally located over the upper portion the supporting structure; drive means coupled to a shaft to provide rotational movement to the shaft; a cylindrical body having a longitudinal opening in an eccentric reference axis, which is coupled to the shaft through its longitudinal opening, in an eccentric position; at least one hollow cylinder coupled with each cylindrical body having attached supports to its outer part which are connected to neck ring holder arms so that, by means of a first sliding movement of the hollow cylinder on the cylindrical body, it provides a lateral movement to open and close the neck ring holder arm supports in parallel and, by means of a rotational movement, it moves the neck ring holder arms with a 180° movement from a parison mold to a finish blow mold.

This invention eliminates the need for a manual work of applying a mold release lubricant to blow molds and bottom molds by workers and reduces a burden on workers involved in the mold release lubricant application work while also increasing the safety of workers during mold release lubricant application, reducing downtime associated with the mold release lubricant application work, reducing changes in the mold release lubricant application locations and variations in amount of application for the blow molds, and, furthermore, contributing to a glass bottle quality stabilization. The application equipment (40) for applying the mold release lubricant is structured to apply the mold release lubricant to at least either a part of blow mold forming surfaces (31f) provided on the blow molds (31), or the entire surface of bottom mold forming surfaces (32f) provided on the bottom molds (32) located in the lower part of a finish molds (31), or both.

There is provided a method of manufacturing a glass container that can manufacture a glass container, which includes a bubble formed in a bottom portion and independent of the outside, with high yield by accurately controlling the position and size of the bubble. A method of manufacturing a glass container that includes a mouth portion, a body portion, and a bottom portion, includes: a step of molding a glass container, in which a bubble is not yet formed, from molten glass; a step of forming a bubble-forming passage by pulling out a needle-like member after inserting the needle-like member into a bottom portion of the glass container in which a bubble is not yet formed; a step of injecting air from an inlet of the bubble-forming passage to form a reverse teardrop-shaped internal space, which is widened in the bottom portion from the bubble-forming passage as a starting point, in the bottom portion of the glass container in which a bubble is not yet formed, and to obtain a glass container that includes an internal space communicating with the outside; and a step of closing an inlet side of the reverse teardrop-shaped internal space by flow of not yet cured glass, which is caused by the potential heat of the not yet cured glass, to obtain a glass container that includes a bubble formed in the bottom portion and independent of the outside.
