The 34 D needle (needle system 34) has a triangular point for working leather, synthetic leather and other coated materials – never for woven fabric, since the cutting action would sever the weave threads. It is used in industrial sewing machines for leather and synthetic-leather work, where the cutting point produces a clean puncture. 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 to 522, 3216, 72122).
In size NM:90/SIZE:14, this version is especially well suited to thinner to medium-weight leather. A sewing thread in the range Nm 80/2 to Nm 50/2 is usually suitable; a bonded polyester or nylon thread such as Amann Serabond, Amann Strongbond or Coats Dabond is recommended. A cutting point is required here to create clean puncture channels in firm materials.
