METHOD OF FORMING A BELT STRUCTURE FOR A PNEUMATIC TIRE
20210197510 · 2021-07-01 ·

A method of forming a belt structure for a tire includes providing a drum having a center section. A first drum edge is near a first edge of the center section and a second drum edge is near a second edge of the center section. A first end surface extends from the center section first edge to the drum first edge and a second end surface extends from the center section second edge to the drum second edge, and a radius of each end surface is smaller than the center section radius. A rubber strip reinforced by a plurality of cords includes an outer edge and an inner edge. The strip is wound about the drum, turning from a first winding angle to a second winding angle on an end surface to reduce the tension and length differential between cords at the outer edge and inner edge of the strip.

PNEUMATIC TIRE

A pneumatic tire is described which includes a tread, a carcass and a belt structure interposed between the carcass and the tread. The belt structure includes a first and second working belt, wherein the angle of the working belts range from about 12 degrees to about 30 degrees, wherein the belt structure further includes a low angle belt located between the working belts. The first working belt is the radially innermost belt, and is the widest belt. The second working belt is radially outward of the low angle belt, and has first and second lateral ends that are located adjacent first and second lateral belts. The first and second lateral belts are low angle belts. The pneumatic tire may further include an optional third working belt, that is the radially outermost belt.

System for monitoring the inflation pressure of the tires of an aircraft
11110758 · 2021-09-07 · ·

System for monitoring the inflation pressure of the tires of an aircraft comprising a pressure sensor carried by each of the wheel rims of an aircraft and delivering an inflation pressure for each of the tires mounted on these rims, a processing unit ensuring the conversion of the different tire inflation pressures into values that can be used by a display device making these different tire inflation pressures available to a pilot or a maintenance operator, the processing unit being distributed in each of the aircraft wheel covers and configured on the one hand to communicate with the wheel pressure sensor via a short-distance wireless communication link and on the other hand to ensure the transmission of the tire inflation pressure coming from the pressure sensor towards the display device via a medium-range wireless communication link.
