The corkscrew spiral of the invention can be mounted on any conventional corkscrew device and has a pointed extremity to facilitate its introduction into the cork in a known manner, and the opposite extremity is conformed as substantially joined turns (1a) having a diameter which is equivalent to the remainder of the spiral and forming an axial orifice to which a roller bearing (2) has been coupled externally, with its central axial orifice facing said group of turns in order to provide for the passage of an element (3) intended to fix the roller bearing to the spiral.
L'invention concerne une spirale perfectionnée pour tire-bouchons pouvant être montée dans tout tire-bouchon conventionnel, présentant une extrémité en pointe destinée à être introduite dans le liège et une extrémité opposée formée par diverses spires (1a), sensiblement unies, dont le diamètre est égal au reste de la spirale. Ces spires forment un orifice axial et sur leur partie externe est accouplé un roulement (2) dont l'orifice axial central se trouve face à l'orifice de ce groupe de spires permettant ainsi le passage d'un élément (3) de fixation du roulement à la spirale.
