The vacuum passage 196 is connected by a flexible pipe (not shown) and an on-off valve (not shown) to a supply of vacuum. There is a period during which the parison is stationary at the intermediate station and is reheating, between the first and second cycle portions. For example, to manufacture very light containers a parison is required which is, proportionately, shorter than normal in relation to the final container. Bag Text 10 shows a timing diagram of operation of the section in which a comparatively short period is allowed for reheating of the parison. xapMM Schema internal Contains list of priorities (country code, publication number and date) of the patent Maschine zum Herstellen von Glaswaren, Timing d'arrive d'une paraison dans une machine I.S.

Seq Text Application Individual section glass container forming machine, Application filed by Emhart Glass Machinery Investments Inc. Therefore, as soon as the path is clear, neck ring mechanism 19 is positioned to move immediately fully back into blank station A ready to receive the next set of gobs to be formed into parisons. 7 In an individual section (IS) machine glassware forming system (10) that includes a gob distributor (16) for delivering glass gobs to individual machine sections (20a, 20b---20n) in sequence, blank molds (30) at each machine section for forming gobs into blanks and blow molds (32) at each machine section for forming the blanks into hollow glass containers, apparatus for timing arrival of the gobs at each machine section and terminating operation of a section in the event of an imminent gob misload comprises gob sensors (40, 42) and associated electronics (44, 46) for determining gob arrival timing at each machine section. The gob arrival timing so determined is compared to a preset shut-down limit at each machine section. As will appear, the carriage 100 is in the form of a closed box and air is supplied to the carriage through flexible bores 185 to provide air for cooling the mould member 13, and vacuum is supplied to the carriage through a flexible bore (not shown) to provide for the supply of vacuum to the mould cavities. classification-ipcr/text, or B511, B512 - See WIPO ST8 for content structure description The air is supplied to each passage 175 from the plenum chamber at substantially the same pressure. 3, FIG.

N')].uJr 3). en The carriage 100 is then caused to move by the piston and cylinder device 106 to carry the initially formed containers from the intermediate station B to the final forming station C. While this movement takes place the vacuum applied to the mould cavities is maintained-and thus the initially formed containers are held firmly in the mould cavities and can move without any risk of distortion. external In an individual section (IS) machine glassware forming system (10) that includes a gob distributor (16) for delivering glass gobs to individual machine sections (20a, 20b---20n) in sequence, blank molds (30) at each machine section for forming gobs into blanks and blow molds (32) at each machine section for forming the blanks into hollow glass containers, apparatus for timing arrival of the gobs at each machine section and terminating operation of a section in the event of an imminent gob misload comprises gob sensors (40, 42) and associated electronics (44, 46) for determining gob arrival timing at each machine section. The plenum chamber comprises tapering walls 176 extending downwardly from the supporting plate 174 and a tubular portion 177. endstream No. CountryCode Consequently there tended to be inadequate cooling of the finish end portions of the parisons, resulting in damage and distortion firstly when the parisons were transferred from the neck-ring mechanism to the intermediate jaws and again when the reheated parisons were transferred from the intermediate jaws to the blow moulds. Air under pressure is supplied to the bore 70 on both sides of the piston head 74 through bores (not shown) in the block 2. KindCode European Patent Office After the potentially misloaded glass is cleared and any necessary repairs are made, the machine section may be restarted employing normal restart techniques. bibliography In this way, damage to the blank molds and generation of tramp glass are prevented while the section is cleared of acceptable glassware.

DocId InstanceID Property a blank station having mold means for forming a gob of molten glass into a parison. Contains list of proprietors of the patent document No. Should the takeout mechanism be of a conventional type which takes the containers out from final forming station C in an arcuate path it only has to raise the containers a short distance upwards before the bases of the containers are clear of the base plates 108 and the carriage 100 can start its motion towards intermediate station B ready for mould members 13 to receive the next set of parisons. Each blow mould also comprises a base plate 108. The carriage 100 is arranged to be moved between an intermediate position, in which it is at the intermediate station B, and a final position, in which it is at the final forming station C, by a piston and cylinder device 106. This plenum chamber 172 is arranged to supply air to each of a plurality of passages 175 defined by and passing through the supporting plate 174. 9 Assignors: EMHART GLASS MACHINERY INVESTMENTS, MANUFACTURE, SHAPING, OR SUPPLEMENTARY PROCESSES, Blowing glass; Production of hollow glass articles, Blowing glass; Production of hollow glass articles in gob feeder machines, Blowing glass; Production of hollow glass articles in gob feeder machines in "blow" machines or in "blow-and-blow" machines, Blowing glass; Production of hollow glass articles in gob feeder machines in "blow" machines or in "blow-and-blow" machines in machines with turn-over moulds, Details of blowing glass; Use of materials for the moulds, Glass-blowing moulds not otherwise provided for, Mould holders ; Mould opening and closing mechanisms, Mechanisms for holders of half moulds moving by rotation about a common vertical axis, Mechanisms for holders of half moulds moving by linear translation, Blow heads; Supplying, ejecting or controlling the air, EMHART GLASS MACHINERY INVESTMENTS INC., DELAWARE, ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNOR:JONES, STANLEY PETER;REEL/FRAME:007770/0873, ASSIGNMENT OF ASSIGNORS INTEREST;ASSIGNOR:EMHART GLASS MACHINERY INVESTMENTS;REEL/FRAME:009845/0879, Improvements in the manufacture of glass containers, Invert arm assembly for glassware forming machine, Glassware forming machine molds opening/closing device, Mold actuating and cooling assembly for a glassware molding machine, Method and apparatus for making wide mouth hollow glass articles, Individual section high speed glassware forming machine, Apparatus for forming glassware with shifting invert and revert mechanism, Plural glass forming machines with lehr conveyor, Transfer means of glassware forming machines, Cyclic process of forming glassware in an individual section glassware forming machine, Parsion transferring and article removing in glassware forming machines, Moulding mechanism for a glassware forming machine, Transfer mechanism for high speed press and blow individual section glassware forming machine, Device for the production of hollow glass articles, Glassware forming machine of the I.

FIG. Provides a structure for describing bookmarks of a patent document [<>] 1 external The mould mechanism in the carriage 100 also comprises a plenum chamber 172 extending downwardly from the supporting plate 174. Alternatively, a downward movement of the base plates 108 can be obtained by the motion of the piston and cylinder device 178, 180 to allow the containers to be removed horizontally from final forming station C. The single cycle of the section just described will be understood to provide a method in which the following steps are carried out: (a) supplying a gob of glass to a parison mould at the blank station of the section; (b) forming a downwardly facing parison at the blank station with a finish end portion of the parison in contact with a neck-ring mould of an invert mechanism; (c) inverting the parison held by the neck-ring mould to transfer it to the intermediate station of the section; (d) closing blow mould members about the parison at the intermediate station, performing an initial forming operation on the parison to force it into contact with the interior surface of the blow mould members to provide an initially formed container and releasing the parison from the invert mechanism; (e) moving the blow mould members linearly from the intermediate station to the final forming station and performing a final forming operation to produce a formed container; and.
