Systems and methods for measuring the temperature of glass during tube conversion
A system for producing articles from glass tube includes a converter having a base with a plurality of processing stations and a turret moveable relative to the base. The turret indexes a plurality of holders for holding the glass tubes successively through the processing stations. The system further includes a thermal imaging system that includes a thermal imager coupled to the turret for movement with the turret. The thermal imaging system may also include a mirror coupled to the thermal imager and positioned to reflect infrared light from one of the plurality of holders to the thermal imager. The thermal imaging system may measure one or more characteristics of the glass tube during the conversion process. Processes for controlling the converter using the thermal imaging system to measure one or more process variables are also disclosed.
Tungsten containing forming mandrel for glass forming
A molding tool, a method, and an apparatus for hot forming of glass are provided that provide glass products used for pharmaceutical packaging. The molding tool includes a forming mandrel for reshaping at least a portion of a heated region of a glass precursor. The mandrel has a temperature-stable core material and an alloying element. The core material is made of precious metals, in particular of platinum group elements, and the further alloying element is made of one of tungsten, zirconium, rhodium, molybdenum, and rhenium.
Lead Insertion System
A lead insertion system adapted to insert a lead into a glass tube includes a first robot on which a first gripper is mounted and a second robot on which a second gripper is mounted. The first gripper grips the glass tube and the second gripper grips the lead. The lead insertion system includes a flame heater heating the glass tube gripped by the first robot and the lead gripped by the second robot with a flame. The second robot inserts the lead into the glass tube held by the first robot with the lead heated by the flame and the glass tube heated and softened by the flame.
HOT-FORMING TOOL FOR PRODUCING GLASS CONTAINERS
A hot-forming tool for producing glass containers is provided. The tool includes a forming roller, a holder, and a heat sink. The forming roller has a forming surface. The holder receives the forming roller with the forming roller rotatably mounted on the holder. The heat sink is directly or indirectly connected to the holder. The forming roller is in thermal contact with the heat sink and the heat sink has an internal cooler so that process heat can be transferred from the forming roller to the heat sink.
METHOD AND APPARATUS FOR THE HOT FORMING OF GLASS WORKPIECES, AND HOT-FORMED GLASS CONTAINER
An apparatus for producing a glass workpiece includes: a device configured to heat a glass until it softens; an inner molding tool configured to mold inner lateral surfaces of the workpiece; an outer molding tool configured to mold outer lateral surfaces of the workpiece, the outer molding tool having a shaping roller with a shaping surface; an accommodating device configured to accommodate the shaping roller, the shaping roller being mounted in a freely rotatable manner in the accommodating device and is fixable during a shaping process by a lockable locking device, the shaping roller being locked with a releasable connection such that the shaping roller can be released and rotated through an angle in the locking device between individual shaping processes; and an apparatus configured to apply a lubricating oil to the shaping surface of the shaping roller and having an outlet opening configured to dispense the lubricating oil.
Method of making a disposable vial for packing tobacco to be smoked
A vial for packing a substance to be smoked from the vial and a method of manufacturing the vial, the method of manufacturing including providing a glass vial, the glass vial having a first end portion and a second end portion connected by a tubular portion having a hollow interior, the first end portion being open and the second end portion being closed; applying heat to a section of the tubular portion to heat the section of the tubular portion; applying a pressure around the heated section of the tubular portion to collapse the section of the tubular portion into the hollow interior of the tubular portion; pressing the first end portion and the second end portion together until an exterior surface of the tubular portion surrounding the collapsed section is level with a remaining exterior surface of the tubular portion; and forming an opening in the second end portion.
METHOD OF PRODUCING GLASS VIALS
A method for producing glass vials, in particular pharmaceutical vials or pharmaceutical ampoules, from a glass tube is provided, the method including the following steps: (a) rotating the glass tube about a longitudinal axis thereof; (b) locally heating the glass tube from one side by means of at least one burner to at least the softening temperature of the glass; (c) reducing the diameter by pressing at least one forming body laterally against the heated region; and (d) separating the glass tube by means of a burner. A glass vial produced in such a way releases a reduced amount of alkali in accordance with ISO 4802 and has a decreased delamination tendency. Furthermore, in the hot-formed peripheral region, the alkali content is only slightly reduced when compared with the alkali content in the glass interior.
Method of making a disposable vial for packing tobacco to be smoked
A vial for packing a substance to be smoked from the vial and a method of manufacturing the vial, the method of manufacturing including providing a glass vial, the glass vial having a first end portion and a second end portion connected by a tubular portion having a hollow interior, the first end portion being open and the second end portion being closed; applying heat to a section of the tubular portion to heat the section of the tubular portion; applying a pressure around the heated section of the tubular portion to collapse the section of the tubular portion into the hollow interior of the tubular portion; pressing the first end portion and the second end portion together until an exterior surface of the tubular portion surrounding the collapsed section is level with a remaining exterior surface of the tubular portion; and forming an opening in the second end portion.
A TAPERED GLASS TIP FOR USE WITH SMOKABLE SUBSTANCES CONTAINED WITHIN A WRAP AND METHOD FOR MANUFACTURING THE TIP
A tapered tip for being attached to a wrapper containing a smokeable substance. The tip is formed by a tube having a conical frustrum shape having two ends forming first and second openings at opposite ends of the tube. The openings are fluidly connected to each other by a chamber disposed between the two ends. The chamber and the two are axially aligned. The tip is formed by rotating a tube while applying heat to a section. The heated section is squeezed and a pivoting rod is inserted. The rollers and rod are removed and heat is applied. The heated portion is squeezed a second time and the rod is reinserted. The rollers and rod are removed and heat is applied. The heated portion is again squeezed and the pivoting rod is again reinserted. The rollers and rod are removed and heat is applied to the end of the tube.
Method for laser-assisted reshaping of glass bodies
A method is provided for reshaping a glass body rotating about its longitudinal axis. The method includes using a means for establishing a temperature profile, a radial forming tool and an axial forming tool. In the method, a first temperature profile is established and the glass body is reshaped by engaging the radial forming tool. Then a second temperature profile is established and the glass body is reshaped by engaging the axial forming tool.
