Title (EN) EMBOSSING FOR ELECTRO DISCHARGE TEXTURED SHEET
(FR) EMBOSSAGE POUR FEUILLE TEXTURÉE PAR DÉCHARGE ÉLECTRIQUE
Abstract:
(EN) An apparatus and method for applying an EDT texture to an aluminum sheet has a rolling stand with at least one EDT surfaced roll capable of rolling the sheet at reductions < 1 %. The rolling is conducted with residual or no lubrication and imparts a texture on the scale of about 1 pm to the surface of the sheet at low roll force.
(FR) L'invention concerne un appareil et un procédé pour appliquer une texture par décharge électrique (electro discharge texture - EDT) à une feuille en aluminium, présentant une cage de laminage pourvue d'au moins un rouleau à surface EDT pouvant laminer la feuille à des réductions < 1 %. Le laminage est effectué avec lubrification résiduelle ou sans aucune lubrification et confère une texture sur l'échelle d'environ 1 pm à la surface de la feuille à une faible force de laminage.
