ABSTRACT:
A metallic cable (10) suitable for reinforcing elastomeric articles comprises two or more substantially identical, helically disposed filaments (11, 12, 13) nested together and twisted together, such that the cable has a lay length (L) that is at least two times greater than the pitch length (P) of the filaments. The cable is manufactured by drawing metallic filaments from a bobbin means (31, 32, 33) and then guiding them through a means for deforming (34) that shapes the filaments into helixes. The filaments are positioned beside and against each other such that each filament is in contact with at least one other filament. After a sunken rotating pulley (37) guides the filaments through the hollow bearing (23) of a first flyer (21), first and second rotating flyers (21, 22) twist the helically disposed filaments together to form a cable.
