Abstract

Apparat for å henge en glass- artikkel (3) som skal varmebehandles i en varmeovn fra en roterende kvartsaksel (1), for å understøtte artikkelen (3), hvor forbedringen omfatter et spor (lb) for å motta et sylinderformet fremspring (3a) på den øvre ende av glassartikkelen (3), som har et elliptisk tverrsnitt og som er utformet i den nedre ende på den roterende aksel (1) og et pinnehull (le) for å feste glassartikkelen (3) til den roterende aksel (l), som er utformet på den roterende aksel (l) langs den minste aksen til sporet (lb), hvor klaringen mellom en perifer overflate på sporet (lb) og på det sylinderformede frem- spring (3a) langs den minste aksen til sporet (lb), er satt slik at den ikke er mer enn 0,2 mm, mens klaringen mellom den perifere overflate i sporet (lb) og på det sylinderformede fremspring (3a) langs den lengste akse for sporet (lb) er satt slik at den ikke er mindre enn 0,4 mm.
