Abstract: Metal sleeves are used as carriers for the abrasive layer of sawing beads. Such sawing beads are threaded on a steel cord and are separated by a polymer thus forming a sawing cord for sawing of hard and brittle materials such as stone or concrete. These metal sleeves have a large influence on the overall performance as well as on the cost of the sawing cord. The inventors propose the method of metal injection moulding to make the metal sleeves in large quantities with an optimised geometry which is not possible with the current methods for making the metal sleeves. Over and above the inventive sleeves are particularly well suited for application of the abrasive layer by means of laser cladding. Beads made by laser cladding on the inventive metal sleeves as well as sawing cords comprising such beads are therefore part of the invention.
Abstract translation: 金属套筒用作锯切磨料层的载体。 这种锯齿形带螺纹在钢丝帘线上并由聚合物分离，从而形成用于锯切硬质和脆性材料如石头或混凝土的锯切线。 这些金属套筒对整体性能以及锯线的成本影响很大。 发明人提出了金属注射成型的方法，以使金属套筒大量地具有优化的几何形状，这对于制造金属套筒是不可能的。 超过本发明的套筒特别适用于通过激光包层施加研磨层。 因此，在本发明的金属套筒上由激光熔覆制成的珠以及包括这种珠的锯线是本发明的一部分。

Abstract: A rope (210, 310) having a three-layered structure comprising a core layer, an inner layer and an outer layer, the core layer comprising one strand (225, 315), the inner layer comprising multiple strands (220) with an amount n and the outer layer comprising multiple strands (215) with an amount m, wherein n is an uneven number, and m is a number which has no common divisor with n, each strand is formed by multiple twisted metal filaments. By this structure fretting of the strands is reduced and the life time of the rope is improved. Also, the use of the rope in lifting application and an elevator system comprising such a rope are disclosed.
Abstract translation: 具有三层结构的绳索（210,310），其包括芯层，内层和外层，所述芯层包括一股（225,315），所述内层包含多股（220），其量为 n，外层包含数量为m的多股（215），其中n是不均匀数，m是与n不存在公约数的数，每股由多个扭绞的金属丝形成。 通过这种结构，绞线的磨损减少，绳索的使用寿命得到改善。 此外，公开了在提升应用中使用绳索和包括这种绳索的电梯系统。
