摘要：
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
κ , 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 d
1 , L varying from 1 to 4, and an outer layer (Ce) of M wires (12), M being no lower than 5, with a diameter d
2 and helically assembled at a pitch p
2 around the inner layer (Ci); and having the following characteristics (d
1 , d
2 and p
2 being given in mm): - 0.10 1 2 2 κ , 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.
