<p>A die structure for forming a composite rubber-cord strip is provided having a die throat whose aperture width at entry is greater than at exit, while its height at entry is smaller than at exit, thus providing a substantially constant cross-sectional area of the throat throughout; rubber is supplied to the entry along a path parallel to the cords, and from a cord guide whose hole spacing is greater than the cord spacing in the ply at the die exit.</p> |
