A method of producing support pillars for use in the fabrication of evacuated glass panels and, in particular, for use in the fabrication of evacuated glazing. The method comprises the steps of: (a) forming in opposite surfaces (15, 16) of a metal blank (10) periodically spaced pairs of aligned linearly extending indentations (13, 14 and 17, 18) and, as a consequence, creating regions of weakness (23) that extend between troughs (24) of the respective pairs of indentations, and (b) parting individual support pillars (28) from the metal blank (in which the indentations are formed) at the respective regions (23) of weakness.

L'invention concerne un procédé d'obtention de colonnettes intervenant dans la fabrication de panneaux de verres sous vide et plus particulièrement, de vitrage sous vide. Ce procédé consiste a) à former dans des surfaces opposées (15, 16) d'une tôle (10) des paires périodiquement espacées de rainures alignées s'étendant linéairement (13, 14, 17, 18) et à créer des zones de faiblesse (23) qui s'étendent entre les creux (24) des paires respectives de rainures et b) à séparer les colonnettes individuelles (28) de la tôle (dans laquelle sont ménagées les rainures) au niveau des zones de faiblesse (23) respectives.
