Abstract (en)

[origin: WO9965713A1] The inner (1) and outer (3) peripheral elements are interconnected with cross chains (2) mounted in V-shape. The two free ends of these V-shaped cross chains (2) are fixed to the steel wire rope (1) which is the inner peripheral element, whereas the intermediary parts forming the pointed tip of 'V', pass freely through the eyelet of a particular hook (7) which is twisted 90 DEG and provided on the outer peripheral element (3). Thus the intermediary section forming the pointed tip of 'V' shaped zigzag cross chain (2) being the tread, slides freely through the ringed hook (7) and thus provides the variations in the lengths L1 and L2. During the fitting and stretching procedures, L1 and L2 lengths are changed by sliding the zigzag cross chains through the ringed hooks (7) and thus the chains can adapt themselves to the geometry and tensile force of the tire.
