A STEEL WIRE FOR THE REINFORCEMENT OF ELASTOMERS

摘要

A substantially rectangular steel wire with a microroughened surface for reinforcement of elastomers is disclosed. The bare surface of the wire (from which the metal coating for increasing the adhesion to the elastomers is removed) has a brightness factor L between 40 and 55. The continuous and controllable micro-roughening treatment is e.g. an etching operation during pickling and before applying metal coating. Such wire is particularly suitable for use as bead wire.
