Abstract
A method for the sealing of glass tubes in a hot softened state is provided. The method includes softening the glass at a severing zone adjacent to an end portion of the glass tube and rotating the glass tube about its longitudinal axis while being heated until a hot softened state is reached in which the end portion is severed off. The hot softened end portion of the glass tube can be pulled-off from the severing zone by a pulling-off device in such a way that the glass tube is simultaneously heat sealed at the severing zone during the severing process.
