Source sentences:
text: the outer structure is formed by at least two plies formed by threads (cords) of material different from that of the inner structure, the said material having elongation values from 2 to 5 times greater than those of the aromatic polyamide for loads proportional to that of the breaking load, said threads being furthermore arranged in alternately crossing directions from one ply to another, so as to form angles from 7° to 35° with the radial planes, that is angles from 14° to 70° between two successive plies;
text: The outer structure is instead formed by two or more plies having essentially a stabilizing function, in as much as it reduces or opposes those lateral flexures of the tire which take place as the vehicle is driven around a curve.
text: Returning once again to the scope of this invention, all the arrangement obtainable by combining the characteristics described in the text and illustrated in the Figures, which comprise a radial carcase formed by a resistant inner structure formed by one or more plies of threads of aromatic polyamide and by an outer structure formed by at least two plies, in general an even number of plies, formed by woven artificial or synthetic threads with a high stretchability, placed in an alternately crossed configuration, the angle of crossing between the successive plies being from 14° to 70°, and outer structure forming furthermore an element stabilising the lateral flexure of the tire, which opposes the forces directed along the axis of rotation.
