摘要： The present invention relates to a process for the preparation of a glass container from a glass tube in a glass processing machine,
wherein the glass tube comprises a first portion with a first end, a second portion with a second end and a longitudinal axis L tube that passes through the centre of the first and the second end,
wherein the glass processing machine comprises a plurality of processing stations, first and second clamping chucks which are adapted and arranged to hold the glass tube while rotating the glass tube around its longitudinal axis L tube and to transport the rotating glass tube from one glass container processing station to the next one, a heating device and a mold matrix,
wherein the process comprises the steps of
I) heating the glass tube at a defined position between the first portion and the second portion to a temperature above the glass transition temperature while the glass tube is rotating around its longitudinal axis L tube and pulling apart the first portion and the second portion thereby separating the first portion from the second portion and forming a closed bottom at one end of the first portion;
II) moving the mold matrix towards the closed bottom and bringing the mold matrix into contact with the closed bottom;

wherein, while bringing the mold matrix into contact with the closed bottom in process step II), a distance Y m between the mold matrix and the first clamping chuck is decreased stepwise.
The present invention also relates to glass containers and to a glass processing machine.

摘要： The present invention relates to a glass container (100) comprising as container parts
i) a glass tube (101) with a first (102) and a further end (103), the glass tube (101) having a wall thickness d w and an outer diameter d c ;
ii) a glass bottom (104), wherein the glass bottom (104) closes the glass tube (101) at the first end (102);
iii) a curved glass heel (105) extending from an outer area (106) of the glass bottom (104) to the first end (102) of the glass tube (101);
wherein the curved glass heel (105) is defined by an outer radius (r o ), an inner radius (r i ) and a thickness of the glass (d h ) in the curved glass heel and wherein the following condition is fulfilled: 100 × d h 3 × r i / d w × d c 2 + 4.4 mm 2 / d c > 0.55 mm .
The present invention also relates to a process for the preparation of a closed glass container (121), to a closed glass container (121) obtainable by this process and the use of a glass container (100) for packaging a pharmaceutical composition.

摘要： Apparatus and method for producing elongated glass components with low bow. The apparatus may include a heating element to heat a bulk glass component where a strand may be drawn from the bulk glass component in a downward direction and a gripper device including a clamping element to support the strand while pulling or drawing it from the bulk glass component in a linear motion, and a low-friction mounting element attached to the clamping element which allows translational movement of the clamping element in an x-y plane. The gripper device may further be used to reduce bow in the strand while it is being drawn by moving the clamping element on the mounting element in a direction opposite the direction of any measured transverse acceleration.

摘要： Ein bekanntes Verfahren zur Herstellung eines Rohres (22) aus Glas umfasst ein zonenweises Erhitzen und Erweichen eines um seine Rotationsachse (6) rotierenden Hohlzylinders (2) mittels einer bewegbaren Heizzone (20), wobei durch radiales Dehnen des erweichten Bereichs unter der Wirkung einer Zentrifugalkraft und/oder eines in der Hohlzylinderbohrung anliegenden Innenüberdrucks kontinuierlich das Glasrohr (22) geformt wird. Um hiervon ausgehend, ein Verfahren anzugeben, das es erlaubt, einen Hohlzylinder (2) in einem einzigen oder in möglichst wenigen Umformschritten zu einem Glasrohr (22) mit großem Außendurchmesser und hoher Maßhaltigkeit umzuformen, wird erfindungsgemäß vorgeschlagen, dass das Bereitstellen des Hohlzylinders (2) das Ermitteln einer Umfangsposition umfasst, an der die Wanddicke gering ist, und dass beim Erhitzen und Erweichen des rotierenden Hohlzylinders (2) ein Kühlmittel (18) auf die Umfangsposition mit geringer Wanddicke im Bereich der Verformungszone (14) periodisch einwirkt.
摘要翻译：提供一种方法和装置，用于通过在围绕其旋转轴线旋转的同时通过可移动加热区域的中空圆筒的加热和软化进行加热和软化来制造玻璃管。玻璃管在离心力作用下和/或内部超压施加在中空缸孔中的作用下，通过软化区的径向膨胀连续地形成。该方法和装置使得可以通过确定壁厚相对较小的圆周位置，将单个或少数成形步骤中的中空圆筒变形为具有较大外径和高尺寸精度的玻璃管，以及在加热和软化旋转中空圆筒期间，只有当主要是具有较小壁厚的圆周位置通过冷却剂源时，冷却剂才从冷却剂源分配到变形区上。
