PROCESS TO CONNECT TOP TO TOP AND PARALLELLY TO THE REINFORCEMENT ELEMENTS, THE RIMS OF A FABRIC INTENDED FOR THE MANUFACTURE OF A RADIAL AND PNEUMATIC HOUSING ARMATURE HAVING TWO FLANKS GATHERED BY A RAIL FLOOR, A TOP AROMATOR AND A ROOF ARMOR

摘要

The method for end-to-end joining of the edges of a rubberised fabric formed from reinforcing elements which are parallel to each other and separated by a distance p, consists in injecting, under pressure and hot, between the reinforcing elements of the edges separated by a distance having a value d greater than 1.5 p, a rubber mix having cohesion and green strength properties superior to the same properties of the mix embedding the reinforcing elements. In the pneumatic tyre produced from a single fabric, the joining mix has a tensile modulus of elasticity greater than the same modulus of the mix embedding the reinforcing elements of the radial-ply carcass strengthening. …IMAGE…
