The invention relates to an installation that is used to perform operations for forming glass or crystal pieces (21), comprising: at least one drive wheel and at least one idler wheel (3); a support element which is driven by the drive wheel; main mandrels (7) which are supported by the support element and which, in turn, each support a first end of a glass or crystal piece (21); and work stations. According to the invention, at least one wheel takes the form of a carousel (2) which comprises secondary mandrels (8), numbering fewer than the main mandrels (7), and which co-operates with the moving support element. Each secondary mandrel (8) opposes a main mandrel (7) along a common axis (23) and supports the second end of the glass or crystal piece.
