Abstract
A steel structure adapted for the reinforcement of elastomeric members has steel elements containing a plurality of steel filaments at least one of which filaments is provided with first and second crimps. The first crimp lies in a plane that is substantially different from the plane of the second crimp. Application of the both crimps can be carried out efficiently using two pairs of toothed wheels which are not externally driven. This arrangement renders it possible to obtain steel structures with an increased penetration of rubber or with an increased elongation at break.
Claims12
A steel structure adapted for the reinforcement of elastomers, said steel structure comprising one or more steel filaments, said steel filaments having a diameter ranging from 0.04 mm to 1.10 mm, said steel filaments having a steel composition comprising a minimum carbon content of 0.60%, a manganese content ranging from 0.20% to 0.90%, and a silicon content ranging from 0.10% to 0.90%, said steel filaments being covered with a corrosion resistant coating or with a coating that promotes the adhesion to rubber, wherein at least one of said steel elements is provided with a first crimp and a second crimp, the first crimp lying in a plane that is substantially different from the plane of the second crimp.
