摘要:
A neck ring mechanism of an H-28 glass forming machine is operated by a neck ring lever which is pivotally supported and controlled by a cam roller which is displaced along a timing cam. To precisely define the timing of the lever, the lever is displaceable relative to a sleeve which is secured to the shaft and a control knob operating through an adjuster plate assembly adjusts the axial location of the lever.

A bottom plate for an H-28 machine is secured to a post which is received within a hollow stud and sits on a ball bearing supported within the stud. The post which has an annular groove cooperates with a plurality of locking pins which can be held in operative relation with the post groove or released by a rotatable collar.
摘要:
A glass forming machine of the rotary table type which utilizes a plurality of individual forming units each of which has a plurality of blank molds and a plurality of blow molds whereby a plurality of glassware articles may be made in a single unit during a cycle. The machine also incorporates an improved neck ring structure, a neck ring quick disconnect, a unique rotating bottom plate structure, a unique blow mold spraying and an improved blow head operating mechanism and an approved structural arrangement. Additionally, a unique delivery system for delivering gobs of glass to the blank molds of the individual forming units is disclosed. The takeout mechanism and transfer mechanism also have unique characteristics.
摘要:
A method of blow molding hollow ware in a paste mold machine includes positioning a blow nozzle in spaced non-sealed relation to the neck ring. During the blowing portion of the molding cycle, air is continuously flowed into and out of the ware so as to simultaneously cool and shape the ware.

A work table in a glass forming unit in apparatus for producing hollow glass articles has an orifice plate which is loosely fitted in a recess of the work table. Therefore, the orifice plate can be removed or mounted on the work table instantly while the orifice plate is firmly secured to the work table during the operation of the work table because the orifice plate expands by the heat of the handled molten glass to be friction-fitted in the recess. The orifice plate is formed of material having a coefficient of thermal expansion equal to, or relatively larger than, that of the work table.
摘要:
An automatic temperature control system for the forming units of a machine of the press and blow type. It comprises a system for automatically sensing the need for and supplying cooling air to the individual forming units, in accordance with heat transfer therefrom, so that controlled temperatures can be maintained in the various units to thereby form ware of uniform characteristics in the various units.
摘要:
In a machine for making bottles or similar containers, from vitreous or plastic material in which a plurality plungers or of rams and tongs cooperating with molds are connected to a turntable for movement with the latter about the axis thereof, a drive for moving the ram parallel to the turntable axis toward and away from the respective mold and the tongs between open and closed positions for holding neck molds and the other mold parts coaxially aligned. The drive for the rams comprises a first cam track arranged stationarily about the axis of the turntable and a roller follower for each ram to move the latter toward and away from the respective mold during movement of the followers along the first cam track and the drive for the tongs comprises a second cam track also arranged stationarily about the turntable axis and a roller follower for each tongs to move the latter between open and closed positions during movement of the roller followers of the tongs along the second cam track. In order to relieve the cam tracks and the followers from excessive strains, to reduce wear of these elements and to make the connection between the follower and the movable elements operated by the same as light as possible to reduce mass forces during fast operation of the machine, a servomotor is arranged between each of the followers and the element moved thereby. Each servomotor is controlled so that the main forces for moving these elements are provided by the respective servomotors.
摘要:
A method of manufacturing hollow glass articles in which glass charges which are severed from a glass stream are shaped into blanks which are deposited on carriers and which are formed in a subsequent forming operation into hollow articles having an open end; because according to the invention the formed articles are removed from the carriers in a position in which their open end is directed downwards, glass chips cannot drop and adhere in or on the articles.
摘要:
Apparatus for feeding gobs of molten vitreous or plastic material into molds of a machine for forming bottles or similar containers from such material in which the molds are moved along an endless path past a loading station at which gob-feeding means are stationarily arranged above the path of the molds, and in which each mold is momentarily arrested when axially aligned with the gob-feeding means so that a gob may be dropped in vertical direction into the respective mold. The molds are transported along a major portion of the endless path with uniform speed equally spaced from each other, but upstream and downstream of the loading station decelerated or accelerated in such a manner so as to arrive at a point downstream of the loading station at the same time as if they would have been moved continuously with said uniform speed.
