Abstract
Official abstract text for this publication.
A rubber-steel hybrid cord of the present invention is characteristically formed by twisting a plurality of sheath filaments or sheath strands around a core in which a periphery of and space surrounded by one or a plurality of core filaments or a core strand are coated or filled with a filler rubber (A) containing an adhesion promoter, thereby forming a multilayer-twist steel cord or a multi-twist steel cord, and coating an outer surface of the multilayer-twist steel cord or the multi-twist steel cord with a coating rubber (C). Further, an amount of an adhesion promoter contained in the coating rubber (C) is equal to or more than an amount of the adhesion promoter contained in the filler rubber (A).
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber-steel hybrid cord formed by twisting a plurality of sheath strands around a core strand in which a periphery of and space surrounded by a plurality of core filaments constituting the core strand is coated or filled with a filler rubber (A), thereby forming a multi-twist steel cord, and coating an outer surface of the multi-twist steel cord with a coating rubber (C), wherein an amount of an adhesion promoter contained in the coating rubber…
