The 328 LL needle (needle system 328) has a left cutting point (135°) 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 Dürkopp Adler (classes 069, 104, 105, 166), Singer (classes 45, 46, 47, 132) and Textima (classes 200, 211, 221, 223).
In size NM:160/SIZE:23, this version is especially well suited to very thick, firm leather and multi-layer leather joins. A sewing thread in the range Nm 40/2 to Nm 20/2 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.
