  • Patent number: 12071362
    Abstract: The invention relates to a system for producing a particularly rotationally symmetrical glass container, such as a glass syringe, a glass carpule, a glass vial, or a glass ampoule, from a particularly rotationally symmetrical glass tube blank, which defines a rotational axis, comprising a chuck for mounting the glass tube blank in a rotating manner, a length-cutting device for cutting to length glass containers of predetermined length from the glass tube blank, and an air bearing, which is arranged downstream of the chuck and upstream of the length-cutting device, for contactlessly mounting the glass tube blank.

  • Patent number: 11851359
    Abstract: The invention relates to a device for reshaping a rotating glass intermediate, in particular a glass tube, comprising at least one shaping roller, which is translationally displaceable into a shape-rolling contact with the glass intermediate for shaping, and comprising at least one linear motor for the translational positioning of the at least one shaping roller in such a way that the shaping roller directly follows a translational positioning movement of the translator of the linear motor.

  • Patent number: 11827554
    Abstract: The invention relates to a method for producing glassware, in particular rotationally symmetrical glassware, such as a glass syringe, a glass carpule, a glass vial or a glass ampule, wherein the method comprises the steps of rotating a glass intermediate, in particular a glass tube, with a receptacle rotational speed about a receptacle rotational axis, rotating at least one forming roller with a roller rotational speed about a roller rotational axis, and displacing the at least one forming roller and the glass intermediate for shaping in a forming roller contact, from which the receptacle rotational axis is spaced in a radial direction about an intermediate radius and from which the roller rotational axis is spaced in a radial direction about a roller radius, wherein the ratio of the roller rotational speed to the receptacle rotational speed during the method is controlled as a function of the ratio of intermediate radius to roller radius.

  • Patent number: 10981822
    Abstract: A device for producing a high-purity medical glass container from a hollow cylindrical glass blank extending along an axial direction (X) and having at least one open end, wherein the glass blank has a mouldable moulded section extending in the axial direction (X) from the open end. The device comprises a first moulding tool and a second moulding tool, where the first moulding tool has a moulding pin. The moulding pin can be moved via the open end of the hollow cylindrical glass blank in the moulded section thereof along the axial direction (X), wherein the moulding pin is fixed in a fixing unit of the first moulding tool. The moulded section can be deformed by the second moulding tool in such a way that an inner surface of the moulded section is in contact with the moulding pin, whereby the moulded section forms a channel.

  • Publication number: 20190030564
    Abstract: A coating method is provided, in which at least one emulsion and/or one solution is applied at least to a first partial area of a surface of a component, said emulsion and/or solution containing at least one layer-forming substance, and then the component is heat-treated, wherein at least one second partial area of the first partial area is subsequently exposed to a plasma, wherein the carbon content of the coating decreases to less than about 80% or less than about 75% or less than about 70% or less than about 60% of the initial value prior to the plasma treatment. A workpiece and a method for the production thereof is provided.
