Abstract: The invention relates to a method and apparatus for shaping an elongated glass body 81, which is a glass tube or glass rod and has an initial profile, to an elongated glass body having a different profile. In order to be properly shaped, an elongated glass body 81 passes through, in a hot malleable state, a nip, which is formed by squeezing rollers 1 and which has a nip width which is less than an outer dimension of the initial profile.In order to accomplish an enhanced precision of the shaping process, according to the invention the position of at least one of the squeezing rollers is varied continuously so that a contact area between the respective squeezing roller and the hot glass body is varied cyclic reciprocating movement. Disturbing effects such as local overheating of the squeezing rollers or an accumulation of dirt or glass particles on the surface of the squeezing rollers can thus be effectively prevented.

Abstract translation: 本发明涉及一种用于将具有初始轮廓的细长玻璃体81（其为玻璃管或玻璃棒）成形为具有不同轮廓的细长玻璃体的方法和装置。 为了适当地成形，细长的玻璃体81以热的可延展状态通过由挤压辊1形成并且具有小于初始轮廓的外部尺寸的辊隙宽度的辊隙。 为了实现成型加工的精度提高，根据本发明，至少一个挤压辊的位置连续变化，使得各挤压辊与热玻璃体之间的接触面积发生循环往复运动。 因此可以有效地防止诸如挤压辊的局部过热或者挤压辊表面上的污垢或玻璃颗粒堆积的干扰效应。

Abstract: A drinking implement includes a first end section with a first opening and a second end section with a second opening. A wall made of glass extends from the first opening to the second opening. At least one of the first end section or the second end section is designed as a specific end section having at least partially a ridge, an outer edge, and an inner edge. An outer transition angle and an inner transition angle both have absolute values of less than 90 degrees.

Abstract: A glass rod includes: a glass including a glass composition, wherein the total relative length variation of the semi-major axis tlvmajor is determined as an absolute difference between (a) a smallest semi-major axis length Imajor(n) and (b) a largest semi-major axis length Imajor(n), normalized by the average semi-major axis length lmajor(a); wherein the 50 equidistant cross-sections are positioned along the length lrod of the glass rod, starting at a position of 0.01*lrod as a first position and employing a plurality of additive increments of 0.02*lrod for each subsequent position; wherein the relative local area variation lav is determined as an absolute difference between (c) a cross-sectional area that has the largest semi-major axis length Imajor(n) and (d) an average value of the cross-sectional areas, normalized by an average value of the cross-sectional areas; wherein the quality index (tlvmajor+lav) is 0.090 or less.
