<p>The parent patent described tyres prepd. by injection of liq. rubber moulding matls. into a mould cavity previously lined with two layers of reinforcing matls. comprising net structures of filaments which can be welded together at their cross-over points. This addn. describes such tyres where on of the two layers of net is complemented by at least one additional textile layer having parallel cords of elastic matl., weldable to those of the net, and having a cord axis offset at a greater angle to the circumferential axis of the tyre than are the crossed arrays of the cords of the adjacent net. The extra layer(s) of cords help maintain the orientation of the net cord axes against disorientation by flow of the moulding matl. during injection, esp. if rapid filling cycles are used.</p> |
