The needle of system 34 has a wedge point (pearl point) for working coated and synthetic materials as well as synthetic leather. It is used in industrial sewing machines for coated and synthetic materials, where a cutting point would damage the coating. Suitable machine classes are found, among others, at Singer (classes 45231, 13820, 11, 15), Pfaff (classes 21 FOR LEATHER, 22 FOR LEATHER, 23, 24) and Minerva (classes 326, 521 bis 522, 3216, 72122).
At strength NM:75/SIZE:11, this version is especially well suited to thinner films and light synthetic leather. A sewing thread in the range Nm 80/2 to Nm 50/2 is usually suitable, e.g. from Amann Rasant or Serafil (polyester); for heavy-duty use, a bonded nylon thread. The wedge point displaces the material's fibres instead of cutting them, protecting the coating.
