ABSTRACT:
A device and forming finger for forming a mouth area on a glass vial and a process for forming the glass vial wherein wear of the finger is reduced to a minimum so that better production tolerances for the formed mouth is possible. This is achieved by a forming finger being allocated either to each glass tube of a vial machine, or by providing play to the forming finger, or by providing the forming finger with lateral recesses. Preferably, the forming finger has a ratio of cross-sectional surface to circular segment area of the forming finger which is larger than or equal to 0.55.times.r. The aforedescribed forming fingers are used in all vial machines, in which from many glass tubes in a cycle, step by step vials are produced by rolling and melting the tube pieces.
