摘要:
A cord for reinforcing rubber items, e.g. pneumatic tyres for passenger and goods wehicles, consists of at least three wire filaments (2) arranged around a continuous core filament (3). According to the invention, the core filament (3) consists of a non-metallic material capable of contracting longitudinally when a rubber item (5) to be reinforced is vulcanised. Such a material is, in particular, undrawn nylon. When the rubber item (5) to be reinforced is vulcanised, the core filament (3) contracts and its diameter increases.
