The 134-35 LR needle (needle system 134-35) has a right cutting point (45°) for working leather, synthetic leather and other coated materials – never for woven fabric, since the cutting action would sever the weave threads. In the SERV 8 version, it has an extremely reinforced blade. 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 100-69, 527i-811, 527i-847, 550-867), Pfaff (classes 38 BIS 1937, 39 BIS 1937, 1245, 1295) and Rimoldi (classes 229 ALL CLASSES, 421 OTHER CLASS, 530 ALL CLASSES, 840 - 104).
The available needle sizes are used, among others, for medium-weight leather for everyday leather goods and saddlery work. As sewing thread, a bonded polyester or nylon thread such as Amann Serabond, Amann Strongbond or Coats Dabond is usually recommended, in a thickness matching the needle size chosen. A cutting point is required here to create clean puncture channels in firm materials.
