摘要:
Apparatus (10) for forming a cased glass stream that includes at least one pair of aligned orifices (22, 28) coupled to sources (12, 40) of core and casing glass such that glass flows by gravity from the glass sources through the aligned orifices to form a cased glass stream. The orifices are carried by an orifice housing (44) mounted on a frame (46) for movement into seating engagement of the orifice housing against the core and casing glass delivery mechanisms. A fluid manifold (50) is mounted on the orifice housing, with an inlet (53, 56) for connection to a source of cooling fluid such as air. A plurality of outlets (58) on the manifold are directed toward the area of seating engagement between the orifice ring housing and the core and casing glass delivery mechanisms for cooling the seating area and thereby reducing leakage of glass between the housing and the glass delivery mechanisms. Inasmuch as the cooling air manifold is mounted on and carried by the orifice housing, the manifold outlets are automatically directed toward the seating area upon seating of the orifice housing against the glass delivery mechanisms, and do not require separate replacement or adjustment.
摘要:
A method and apparatus for delivering a coated glass stream having a first inner layer and a second outer layer wherein the method comprises providing a vertical orifice (20;100,102), delivering molten glass from a first source (22) through the orifice, providing a gap (G) about the orifice intermediate its upper and lower ends, delivering glass from a second source (24) about the gap such that the glass from the second source flows through the gap to provide an outer layer about the glass from said first source as it flows through the orifice, and controlling the size (L) and shape of the gap parallel to the flow and the size (G) of the gap perpendicular to the flow such that the gap provides sufficient flow resistance and the gap is of sufficient size and shape to prevent clogging. The method includes the step of providing passages (65) for the flow of the glass from the second source (24) and controlling the size and shape of the passages such that the passages are sufficiently large to minimize flow resistance therein and to provide sufficient pressure to force the glass through the gap and provide less resistance than the metering gap. The method also includes providing a plurality of orifices (100,102), each having a gap, delivering glass from the first source (22) through each of the orifices, delivering glass from the second source (24) to the gaps and controlling the size and shapes of such gaps.

摘要:
Die Aufgabe besteht darin, in einfacher Weise eine Ermittlung des Gewichtes von Hohlglasartikeln bereits während ihrer Herstellung zu ermöglichen, so daß frühzeitig in den Herstellungsprozeß eingegriffen werden kann, mit der Folge einer Reduzierung oder Erhöhung des Gewichtes der herzustellenden Glasartikel. Erfindungsgemäß wird dies dadurch erreicht, daß nach Einbringen des flüssigen Glastropfens in die Vorform eines IS-Maschine die Messung seines Volumens erfolgt. Die Volumenmessung wird durch Bestimmung der Eindringtiefe des Preßstempels in den in der Vorform befindlichen Glastropfen vorgenommen. Die Messung der Eindringtiefe des Preßstempels erfolgt durch Erfassung des vom Preßstempel beim Preßvorgang zurückgelegten Weges. Die erfaßten Werte dienen zur Regelung der Größe der den Vorformen zugeführten Glastropfen.
摘要:
The process uses an Individual Section machine with at least a feeding spout, a plurality of sections comprising molds for forming the containers and a conveyor for transporting the formed containers. Each section operates in a independent manner with its own feeder spout and conveyor to allow an independent production of containers by each section.
