Abstract

La présente invention concerne une aiguille de machine à coudre (1) comprenant une tige (3) située dans le prolongement d'un piston (2), ladite tige présentant sur sa surface périphérique - à partir du chas (8) situé côté pointe - au moins une rainure de fil (11) s'étendant en direction du piston (2). Ladite rainure possède un fond de rainure (12) qui se présente sous la forme d'une surface incurvée (W) disposée en direction transversale de la tige (3), et des parties latérales (15) s'étendant à partir du point terminal de zone incurvée et formant une section de rainure (16) s'élargissant en direction de la surface périphérique (4). L'invention a pour objet l'obtention d'une structure stable à l'utilisation, ayant un contour de rainure adapté au guidage de fil, de sorte que le diamètre (D) de la courbure en arc de cercle de la surface incurvée (W) correspond approximativement au rayon (R) de la tige (3).
