原地橡胶处理的基础线股为双层帘线的多线股帘线
摘要：
本发明涉及一种K×(L+M)结构的多线股帘线，其特别能够用来增强工业车辆的轮胎带束层，该多线股帘线由以捻距PK螺旋组装的K根基础线股构成，每一根基础线股：包括进行了原地橡胶处理的具有L+M结构的两层(Ci、Ce)的帘线(10)，这两层(Ci、Ce)包括直径为d1的L根丝线(11)构成的内层(Ci)以及直径为d2的M根丝线(12)构成的外层(Ce)，L从1至4变化，M不小于5，这M根丝线(12)围绕所述内层(Ci)以捻距p2螺旋组装在一起；并且具有如下特征(d1、d2和p2以mm计)：-0.10＜d1＜0.50；-0.10＜d2＜0.50；-3＜p2＜10；其内层(Ci)包覆有称为“填充橡胶”的橡胶混配物(14)；沿着等于K乘以PK的基础线股的整个长度，所述填充橡胶(14)存在于由所述内层(Ci)的L根丝线(11)以及所述外层(Ce)的M根丝线(12)限定边界的每一个毛细管(15)中，而且在L等于3或4时该橡胶存在于由所述内层(Ci)的L根丝线(11)限定边界的中心通道(13)中；所述基础线股(10)中的填充橡胶(14)的水平为在每g基础线股中5至40mg。
摘要（英）：

The invention relates to a multistrand cord with a K x (L+M) construction, which can be used in particular for reinforcing the belts of tyres for industrial vehicles, consisting of K basic strands helically assembled at a pitch P , each basic strand: comprising a cord (10) having two layers (Ci, Ce) with an L+M construction, rubberised in situ, comprising an inner layer (Ci) made up of L wires (11) with a diameter d1, L varying from 1 to 4, and an outer layer (Ce) of M wires (12), M being no lower than 5, with a diameter d2 and helically assembled at a pitch p2 around the inner layer (Ci); and having the following characteristics (d1, d2 and p2 being given in mm): - 0.10 1 2 2 < 10; the inner layer (Ci) thereof being sheathed by a rubber composition (14) referred to as filling rubber; along the entire length of the elementary strand equal to K times P , the filling rubber (14) being present in each of the capillaries (15) delimited by the L wires (11) of the inner layer (Ci) and the M wires (12) of the outer layer (Ce) and, when L is equal to 3 or 4, the rubber being present in the central channel (13) delimited by the L wires (11) of the inner layer (Ci); the level of filling rubber (14) in said basic strand (10) being 5 to 40 mg/g of basic strand.
