摘要:
A method of and system for forming a glass container, and an apparatus for sensing elongation of a parison in a blow mold of a glassware thrilling machine. A suspended parison is allowed to elongate in a mold along a central longitudinal axis. At least one position of a closed end of the parison is sensed within the mold before the closed end of the parison contacts a transversely extending surface in the mold. A process parameter is adjusted responsive to the sensing step.

Disclosed is a method by which a transparent object can be manufactured, in which transparent object an inclusion is arranged. A spherical object can be a substantially two-dimensional or three-dimensional object. The method includes the following steps, to be performed in suitable sequence, of: a) providing two complementary halves of the object such that at least one of two contact surfaces of the respective halves to be directed toward each other has a central recess which also forms a boundary of a cavity for accommodating at least a part of the inclusion; b) arranging at least said part of the inclusion in said recess; and c) mutually adhering the two halves, for instance by means of the parts of the two contact surfaces extending around the central recess, in order to form the object.

The invention relates to a method, comprising: feeding at least one molten-glass parison into a parison mold; forming, in the parison mold, a blank of an item from said at least one parison; transferring the blank of the item into a finishing mold; and forming the item in the finishing mold. While forming the item in the finishing mold, excess glass is directed out of the base of the item so as to form a convex bulge, and said bulge is removed such that the thickness of the base of the item is substantially constant.

Vertically aligned first (30) and second (32) combined blowhead and takeout mechanisms are provided to sequentially blow glass parisons (P) into containers (C) in a mold set (22) and to transfer blown containers to a deadplate (40) of a glass containing forming machine (20). Each of the combined mechanisms is pivotally suspended about an axis A from a carrier arm (36) that is pivotally attached to an end of an oscillating arm (38), an opposed end of which is pivoted about an axis (B). The axis (B) of each combined blowhead and takeout mechanism is periodically raised and lowered to permit the other combined blowhead and takeout mechanism to oscillate therebeneath, to thereby permit overlapping cycles between the blowhead and takeout mechanisms. Each blowhead and takeout mechanism is provided with a chuck or tong assembly (54) to engage or release each container by its finish (F). Each tong assembly has a plurality of tong elements (74) that are simultaneously moved radially in or out by oscillation of a cam (50) that has a non-circular slot (78) in which a pin (76) carried by each tong element rides.

An I.S. machine is disclosed which has a plurality of individual sections arranged side by side. Each section has a section box for supporting a blank mold opening and closing mechanism and a blow mold opening and closing mechanism. These section boxes are supported on a bed which has a top wall underlying the section boxes. A passages are provided through the bed, beneath the top wall of the bed, from one side to the other side of said I.S. machine and these passages slidably receive a plurality of adjacent fluid ducts. The top wall of the bed further includes openings for exposing each fluid duct within each section so that fluid connections can be established from these fluid ducts through the openings in the top wall of bed.
