The L 83 TOP SUK needle (needle system L 83 TOP) has a medium ball point for working knit fabrics, without damaging the loops. It is used in Schiffli embroidery machines. Suitable machine classes are found, among others, at Futura (classes CE, CE - 10/ 75-F TOP, CE - 10/108-F TOP, CE - 15/108-F TOP) and Lässer (classes L 200, 400, L 83, L 93).
Thinner needle sizes are used, among others, for fine embroidery on light fabrics, and the thicker versions for standard embroidery on medium-weight fabrics. As embroidery thread, a size No. 60 to No. 30 thread matching the needle size chosen is usually recommended, e.g. Amann Isacord. The ball point glides between the loops instead of piercing them, keeping the seam clean and undamaged.
