    摘要: In a method for producing glass bottles having a flat base and an opposite filling opening, the base of the glass bottles is further formed at a plurality of processing positions. During the entire further forming of the base, with the aid of a purge gas which by way of the filling opening of the glass bottle flows in or out in a centric manner and flows out or in in an eccentric manner, a purge gas flow is generated in the interior of the glass bottle in order for delamination effects to be reduced. A tube or a nozzle serves for blowing in or suctioning out the purge gas. Various geometries and arrangements of the tube or of the nozzle are disclosed. A multiplicity of geometric constellations of the tube diameters and various mass flow settings are disclosed.

    摘要: A glass tube, such as a glass tube for the production of containers for storage of pharmaceutical compositions, facilitates production of pharmaceutical containers with high quality. The glass tube has a relative cross-sectional area deviation defined as QF max - QF min 1.5 ⁢ ⁢ m . QF max - QF min 1.5 ⁢ ⁢ m is less than k*x+t. QFmax is the highest cross-sectional area and QFmin is the lowest cross-sectional area of at least two cross-sections of the glass tube, the cross-sections being spaced apart from each other along a length of the glass tube, and k is 0.0023 m−1, t is less than 0.15 mm2/m and x is QF max + QF min 2 .

    摘要: A method for producing ceramizable green glass components provided, as well as apparatus for performing such method and ceramizable green glass components producible by such method. The method is a redrawing process in which a preform is heated, in a deformation zone, to a temperature that enables redrawing of the glass. The deformation zone is particularly small, which permits redrawing of the ceramizable green glass bodies while avoiding ceramization during the redrawing. The method provides plate-like or sheet-like green glass components that have a particularly smooth surface.

    摘要: An apparatus is provided for producing thin glass ribbons from molten glass. The apparatus includes a drawing tank, a direct heater, and an indirect heater. The drawing tank has a lower elongated nozzle opening through which the molten glass can exit downwards. The direct heater has one or more heating circuits operable to heat the drawing tank in a first heating zone. The direct heater has a power source for each on the heating circuits. Each heating circuit has connections to connected to a wall of the drawing tank so that current from the power source flows through at least a portion of the wall and heats the wall. Each heating circuit also includes current-carrying portions of the wall. The indirect heater has one or more heating elements to heat the drawing tank in a second heating zone.

    摘要: A method for controlling the thickness of a glass ribbon and an article produced thereby are provided. The method includes: providing a glass ribbon by drawing from a melt or redrawing from a preform; predefining a nominal thickness of the glass ribbon; determining the thickness of the glass ribbon over its entire net width; determining at least one deviation of the thickness of the glass ribbon from the predefined nominal thickness; identifying the area of the thickness deviation in the glass ribbon; and heating the area of the at least one thickness deviation in the glass ribbon using a laser, so that the glass ribbon attains the predefined thickness.

    摘要: A process for producing glass tubes includes: applying a glass melt onto an outer surface of a rotating conical mandrel by guiding the glass melt from a feed tank through an outlet; forming a hollow glass melt body on the conical mandrel; drawing the hollow glass melt body from the conical mandrel in a predetermined direction toward a front end for forming a glass tube, the outer surface having a wetting zone where the glass strand first contacts the conical mandrel, a spatial variation of the wetting zone of the applied glass melt being monitored by measuring a horizontal movement of an edge of the glass strand; reducing the spatial variation by adjusting one or more process parameters; cooling the hollow glass melt body; and cutting the cooled glass melt body into glass tubes.
