ABSTRACT:
A tire cord which is improved in rubber penetration. The cord has at least four filaments twisted together so as to form a core and a sheath surrounding the core. The filaments change place repeatedly along the longitudinal direction of the cord such that one of the filaments forms the core in a portion, but in a different portion of the cord, the same filament forms part of the sheath.
