    Abstract: A steel cord for reinforcing rubber articles comprises one wave-form or helical core steel filament and a plurality of sheath steel filaments disposed around the core steel filament, the pitch Pc of the core steel filament is 3.0 dc/0.34 ≦ Pc ≦ 10.0 dc/0.34 (dc = diameter of steel core filament) and the core forming ratio Rc = Lc/dc (Lc is an amplitude of the wave or helix of the core steel filament) is within a particular range varying depending on the number of sheath steel filaments. The rubber articles containing the steel cord have an improved resistance to corrosion propagation and a high strength. A pneumatic tire is reinforced with the above-mentioned steel cord and contains a cross belt layer where

    (i) an angle 0 formed by a reinforcing steel cord and the equatorial plane of the tire is :
    (ii) a gap between adjacent two steel cords in the same layer, I, is :
    (iii) a gauge of the gum between two facing cords, G, is :

    The pneumatic tire exhibits suppression of development of crack at the belt end in addition to the advantages as above.

    Abstract: A steel cord (7) comprises a plurality (from 3 to 27) of component steel wires tightly twisted at a regular pitch P from 5 to 20 mm in the same direction. Each wire has a diameter d from 0.1 to 0.4 mm. At least one of the wires (1) includes a spiral portion having a spiral pitch P₁ from 0.1P to 0.7P and a spiral diameter d ₁ from d + 0.02 mm to d + 0.2 mm. At least one other wire (2) includes a straight portion. At any cross section of the cord, 25 to 66% of the wires are spiral and the other wire(s) is (are) straight. The stretch of the cord under a load of 5 kg is from 0.10 to 0.40%. A method of an apparatus for producing such steel cord are described and claimed.

    Abstract: L'invention concerne un cordage flottant utilisé notamment comme cordage de tête d'un filet, l'intérieur dudit cordage comprenant une matière flottante (1) dont la densité est inférieure à 1,0. La matière flottante (1) est en matière plastique thermoplastique réticulée ou non réticulée, comportant des espaces vides pour diminuer la densité et formant dans le sens longitudinal du cordage une région centrale continue de section transversale constante, ou une région centrale s'élargissant et rétrécissant à la manière d'une vague.
