Abstract: A glass tube semi-finished product or a hollow glass product manufactured from the glass tube semi-finished product is provided with a first marking with information on the origin and/or tube-specific production data of the glass tube semi-finished product, which marking is read from the hollow glass product after its manufacture to determine the origin and/or the tube-specific production data of the glass tube semi-finished product, e.g., to identify the semi-finished glass tube from which the hollow glass product has been made, and/or trace the tube-specific production data of this glass tube semi-finished product. This means that the entire supply chain for the hollow glass product from the supplier of the originally used glass tube semi-finished product up to the end product can be determined. The physical and chemical characteristics of the glass tube semi-finished product are not altered for producing the first marking.

Abstract: An apparatus and method for the inspection of a circular elongated element, and bundles of such elements, are provided. The method includes the steps of illuminating the circular elongated element with a first light beam emitted by a first light source; acquiring a first image of at least a part of the first light beam reflected by the circular elongated element; and comparing the first image with a first set point to obtain information about an orientation of the circular elongated element.

Abstract: A method for processing glass elements is provided. The method includes introducing a perforation line for parting a glass element introduced into the glass element during or after a hot processing process at an elevated temperature of at least 100° C. Spaced-apart filamentary flaws are introduced into the glass element along the predetermined course of the perforation line by a pulsed laser beam of an ultrashort pulse laser, and, during or after the introduction of the filamentary flaws, the glass element is cooled down so as to produce a temperature gradient, which induces a mechanical stress at the filamentary flaws, whereby the breaking force required for parting the glass element along the perforation line is reduced.

Abstract: A method for further processing a glass tube semi-finished product includes: providing the glass tube semi-finished product, along with defect data for the glass tube semi-finished product; reading the defect data for the glass tube semi-finished product; and further processing the glass tube semi-finished product, for example by cutting to length or sorting out. The further processing of the glass tube semi-finished product is adapted to the defect data, which were read out for the glass tube semi-finished product. In this way, the further processing can be more efficiently adapted to the respective characteristics of a glass tube semi-finished product to be processed or a specific sub-section thereof, and the relevant defects of the respective glass tube semi-finished product do not need to be determined or measured again.

Abstract: A process for producing a glass tube 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, the glass melt forming a strand of molten glass that flows from the outlet onto the outer surface; 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 strand of molten glass first contacts the conical mandrel, the wetting zone being at a vertical distance from the outlet and a vertical movement of the conical mandrel is monitored; reducing vertical movement of the conical mandrel; cooling the hollow glass melt body; and cutting the cooled glass melt body into glass tubes.

Abstract: A cleaning system for cleaning the inside of a glass element with a fluid includes a nozzle head including a cleaning opening for releasing a part of the fluid and pointing in a first direction and a pressure balancing opening for releasing a part of the fluid and pointing in a second direction. Two half spaces including a first one and a second one are separated by a plane which is perpendicular to a center axis of the nozzle head. A first direction vector of the first direction points in a direction at least one of towards the first half space or away from the second half space. A second direction vector of the second direction points in a direction at least one of towards the second half space or away from the first half space.

Abstract: A glass tube element having a hollow cylindrical section with a shell having an outer diameter is provided. A first ratio is a difference value to a mean value. The difference value is a difference of a minimal and maximal value of the outer diameter. The mean value is a mean of the minimal and maximal values. A sub-section having a start, an end, and a distance of 1 meter measured along a straight line from the start to the end and intersecting with a center axis of the sub-section at the start and the end. The sub-section having, for every point of the center axis, a shortest distance to the straight line. A second ratio of a specific distance to 1 meter, the specific distance being defined as a largest of all shortest distances. A product of the first and second ratio is smaller than 4×10−6.

Abstract: An apparatus and to a method for imaging the inner contour of a tube are provided. The method includes radiating light having a first polarization direction onto a first tube end in the longitudinal direction of the tube; reflecting the light downstream of a second tube end, wherein the light that is returning through the tube due to the reflection has a second polarization direction that is orthogonal with respect to the first polarization direction; and filtering the returning light with a polarization filter to transmit only the returning light.
