Abstract
Abstract Reinforcing elements comprise a plurality of elongated metallic members, with substantially rectangular cross sections, having parallel longitudinal axes and at least one of the wide sides of each being contiguous with a wide side of another of said elongated metallic members. A single wrap member is helically disposed around the elongated metallic members such that each turn of the wrap filament member is spaced apart from the next adjacent turns of the wrap member. Elastomeric articles reinforced with these reinforcing elements are also disclosed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
145 words
A reinforcing element for an elastomeric article comprising a plurality of elongated metallic members having substantially rectangular cross sections of identical width, the longitudinal axes of said elongated metallic members being parallel to one another, a wide side of each said elongated metallic member being contiguous with a wide side of another of said elongated metallic members, the ratio of width to thickness of each said elongated metallic member being at least 2 to 1 but no greater than 10 to 1, and a wrap member helically disposed around said elongated metallic members such that each turn of said wrap member is spaced apart from the next adjacent turns of said wrap member a distance, as measured in a direction parallel to the longitudinal axes of said elongated metallic members, that is at least equal to the width of one of said elongated metallic members.
