The needle of system 134 has a normal round point for working woven and knit fabrics. It is used in industrial lockstitch and general-purpose sewing machines, here mainly for technical applications such as footwear and luggage, bags and leather accessories rather than classic garment production. Suitable machine classes are found, among others, at Pfaff (classes 1243, 2081-748/…, 2083, 2083-748/…), Juki (classes DDL-5550N, DDL-5550N-7, DDL-5550NA, DDL-5550NA-7) and Singer (classes 107-W1, 107-W10, 107-W100, 107-W102).
Thinner needle sizes are used, among others, for light, fine woven and knit fabrics such as blouse and shirt fabrics, and the thicker versions for heavy, multi-layer woven and knit fabrics as well as technical textiles. As sewing thread, a matching thickness is usually recommended depending on the needle size chosen, e.g. from Amann Serafil or Rasant (polyester).
