Abstract:
A method of producing a spirally-shaped wire filament for reinforcing rubber or plastic articles, in which at least two individual wire filaments are twisted together and plastically deformed and then separated from each other, said method comprising the following steps:A1: uncoiling at least two single wire filaments (2) from reels (10),B1: twisting and plastically deforming each of said wire filaments (2) in first false twisters (20),C1: combining said twisted and plastically deformed wire filaments (2) in parallel,D1: intertwining said twisted and plastically deformed wire filaments (2) in a second false twister (40) in a direction of twist opposite to the direction of twist of said first false twisters (20) and means for separating said return-twisted wire filaments (2) to provide at least two single-shaped wire filaments (8) and,E1: separating said twisted and plastically deformed wire filaments (2), after said intertwining in said second false twister (40), to provide at least two single spirally-shaped wire filaments (8).
