Abstract
Reinforcing fabric for articles made from elastomeric material, particularly for pneumatic tires, comprising a plurality of filamentary elements having at least tensile strength, parallel and adjacent to each other in a plane, lying in a predetermined direction. The reinforcing elements, preferably cords, are incorporated in an elastomeric material and constitute at most the 40% of the volume of the fabric.
