摘要： A method for producing glass vials, in particular pharmaceutical vials or pharmaceutical ampoules, from a glass tube is provided, the method including the following steps: (a) rotating the glass tube about a longitudinal axis thereof; (b) locally heating the glass tube from one side by means of at least one burner to at least the softening temperature of the glass; (c) reducing the diameter by pressing at least one forming body laterally against the heated region; and (d) separating the glass tube by means of a burner. A glass vial produced in such a way releases a reduced amount of alkali in accordance with ISO 4802 and has a decreased delamination tendency. Furthermore, in the hot-formed peripheral region, the alkali content is only slightly reduced when compared with the alkali content in the glass interior.

摘要： Disclosed is a method for the production of a tube having, in sections, a non-circular profile by deforming, comprising: a) providing a tube, which has a circular initial profile; b) conveying the tube in a hot, malleable state through a nip, which is formed by squeezing rollers and has a first nip width, which is larger than or equal to an outer dimension of the initial profile; c) adjusting the squeezing rollers for setting a second nip width, which is smaller than the outer dimension of the initial profile, and deforming the initial profile in said hot, malleable state for obtaining said non-circular cross section; and d) adjusting the squeezing rollers for setting a third nip width, which is larger than or equal to the outer dimension of the initial profile, and severing said tube in a region having a circular cross section; so that respective end portions of said tube have a circular cross section According to the invention, the tubes can be connected reliably with connecting-members or other tubes via the end portions having the circular profile using proven tube connection technologies. At the same time there is at least one central section having a non-circular cross section which is of advantage, for example for applications in photobioreactors.
