二輪車用タイヤおよびその製造方法
Document Type and Number:
Japanese Patent JP2012513334
Kind Code:
A
Abstract:
In the manufacture of a tire, a belt structure is made by means of strip-like segments or elements, each comprising parallel cords embedded in an elastomeric layer, sequentially laid along the circumferential extension of a toroidal support, in such a manner that: each strip-like element is laid in a laying trajectory defining, at each point, a laying angle; at each point of the laying trajectory a laying gap is formed between adjacent strip-like elements, the laying trajectory being formed starting from preselected laying angles on the shoulder and on the crown of the tire, the laying gap between adjacent strip-like elements varying along at least one section of the laying trajectory between crown and shoulder so as to cause variation of the laying angle and to obtain the preselected angles on the shoulder and on the crown.
