Abstract
An apparatus and process is provided for the deformation of the heat-softened end of a glass tube. In the formation of hollow articles such as, for example, vials from glass tubes, either large processing pauses occur or the formation elements have to be moved with high speed to the next tube being processed. To keep the processing pause short a forming roller is provided, which is shifted back and forth relative to the glass tube. Shifting of the forming roller takes place in such a manner that the forming roller, toward the end of the rolling, is at the starting position for forming the next glass tube.
